Sattusime üsna intrigeerivale videotestile, kus astuvad Windowsi käivituise kiirust mõõtes vastamisi arvutid odava Celeroni ja kalli i7 protsessoriga, mõlemal SSD-kõvaketas.

Arvutiteks on täpselt sama Windowsi kasutavad HP ProBook 4530s Celeron, millele lisatud 120 GB SSD SATA3 kõvaketas (200 eurot), ja Dell Precision M4600 i7, millele lisatud 256 GB SSD SATA2 kõvaketas (240 eurot).

Kui kallid on masinad ise? ProBook maksab soodushinnaga hetkel 469 eurot, Dell aga 1899 eurot. Nii et hinnavahe on märgatav.

Testi autoritelt saabus veel selline kommentaar:
Kui Windows kiirelt käivitub, teevad seda ka brauser, Word, Excel ning filmid ehk see, mis 90% sülearvuti kasutajatest tähtis on.
Enamus tavakasutajatest mängib flashimänge ega tee videotöötlust, neile see äriklassi odavama otsa HP 4530s ongi just mõeldud. SSDd ei pea täna juurde ostma, selle võib vabalt osta ka aasta pärast, kui see on umbes poole odavam ning arvuti kiirusest puudu hakkab jääma. 256 GB SATA2 SSD maksis alles aastake tagasi üle 600 euro.
Test näitab lisaks, et tavakasutaja arvutis on megabaitide ja gigahertside tagaajamisest hoopis tähtsam kõvaketta kiirus. Revolutsiooni ei too mitte uued i-seeria protsessorid, vaid SATA3 SSD kõvaketta kiirus.
Võrdluseks veel kõvaketaste lugemiskiirustest:
3a vana SATA1 5400 rpm kõvaketta kiirus on ~30 MB/s
3a vana SATA 7200 rpm kõvaketta kiirus on ~40 MB/s
uue SATA2 5400 rpm kõvaketta kiirus on ~60 MB/s
uue SATA2 7200 rpm kõvaketta kiirus on ~70 MB/s
SATA2 SSD kiirus on ~200 MB/s
SATA3 SSD kiirus on ~500 MB/s
Samas ei maksa arvata, et SSD SATA3 tähendab automaatselt 500 MB/s kiirust, nii kiire on see ainult Sandy Bridge'iga arvutites ehk kõige uuemas Inteli seerias. Mõni aasta vanas arvutis jääb kiirus 250 MB/s kanti.
Ning SSD-ketast valides tuleb kindlasti lugeda spetsifikatsioone, kuna turul on palju SSD-kettaid, mille kiiruste vahed erinevad kordades.

Specview test results

Update is here http://www.laptopid.ee/leht/81/Workstation-seeria-sulearvutid/
If there are desktop Archicad, Autocad, Solidworks, 3ds Max, SketchUp, Maya, etc.. Icon and go to work and carrying out the three dimensional world, the following story is for you.
Having sold more than 10 years, laptops, and often encountering 3D draftsman, whose work is a computer video card, which is a good case for playing, but certainly not a serious work in OpenGL, I decided to enlighten a bit workstation series notebooks worldwide.
Broadly speaking, the video cards can be divided into three groups, some of which are designed for office, home, and the other third, which is designed to work in 3D. Office is typically a laptop computer RAM that uses a video card that it is mainly due to the relative slowness of the computer's memory to the video card is capable of running HD videos and Internet sites. Home computer can find a suitable video card to play, which is several times faster than the memory of the computing processor. And 3D work for a computer is often the same video card, faster gaming PCs, with the difference that the processor is attached to the 3D processing commands in hardware-based, and if the program is able to use these commands work is generally 4-5x faster, sometimes even 10 -15x faster. And if we now take into account the net work time into money, rendering the computer screen waiting for 4-5 minutes several times a day is kinda much. However, a fast video card, the computer would do the job in 30 seconds - 3 minutes vs. 50 minutes! In addition, the high-speed computer workstation video card, drawing up to 15x faster and smoother turning. Most workstation series notebooks have two hard drive slots (can be RAID 0 or 1 set), 16GB + of memory and an optional FullHD RGB LED screen that displays 100% of the colors at the same time as a normal LED display shows the ~ 70% of the colors, and this difference in eye already be seen from afar.
The following is a comparison test using SpecView perf 11 programs that will test a 3D video card using the capability.

And finally, a series of workstation laptops generally cost very much, often 3-4x more than the conventional model, it is Laptopid.ee a lot over the years contributed to their sales and now we have several contacts with factories and wholesale warehouses, thanks to which we can offer competing places, more than half of favorable prices. Workstation series laptops are the producers of another label, as the models -
Dell Precision M series (such as the Dell Precision M6500)
HP NW and W series (such as the HP EliteBook 8740w or HP nw8430)
IBM Lenovo W series (for example, the Lenovo W510)
Fujitsu Celsius series (eg Fujitsu-Siemens Celsius H265)

Lenovo T420 vs HP 8640p vs Dell E6420 test

One day, when I read about yet another superlative overview of the computer, I decided to do something about it.
Often reviews are compiled by a computer journalist who is one of the company's näppimiseks laptop (usually with a free nänniga), will write it here and there, and based on technical data that it is a very, very good computer. The result is the manufacturer of the peace, happy with the tester and a satisfied customer, because the test was positive, and her 4-year-old rüperaaliga compared to the layman, even a significant step forward. To remedy the situation and decided to give an objective evaluation of 34 Stone extraction Laptopid.ee laptops lobby that put themselves in a thorough review. Virgo testers and Revo are both engaged in the sale and repair of laptop computers for 10 years, 3 years Karmo. In addition to long experience, we are also unbiased, because Laptopid.ee does not have binding contracts with producers, and there is no definite preference.

We opt out of the test to
As Laptopid.ee is Estonia's largest seller of laptops in business class, we have a wide selection of laptops available locally. After over 10 years of laptops sold in the consumer desires, and knowing we chose the test ostetumad models - 14 "business class.

Selected was the Dell Latitude E6420, HP EliteBook 8460p and the Lenovo ThinkPad T420 (former IBM). A few years ago it would have chosen here to be sure the company of Fujistu Lifebook S series of high class companionship and maybe even Toshiba would fit. Unfortunately, over time the computer manufacturing and service quality has fallen, and fallen, because they no longer Dell, HP, and Lenovo does not offer the competition. Some perhaps will ask now that the Asus, Samsung, Acer, or even Ordi, because these are, after all, a series of business notebooks. The answer to this is simple: your maimukesi the manufacturer wants to appoint both ways, but the essence remains unchanged. Business class is one of the most important features of stability, so these manufacturers can not be guaranteed. For example, if the weight is small and looks good, but the body is like a meat jelly, then unfortunately this machine is 2 years later nothing left. For more information about who and what is the business class, can be read here Link
But we will return to the test. The three laptops, which we chose to test out, the producers of the latest models. Here we had a question: is the latest is still the best? He is definitely faster, no doubt. However, for many, the primary importance of this, the internet page opens in 2.1 seconds or 2.5 seconds? Thus, manufacturers have added a test in the same three of the previous generation of notebooks. A total of 12 laptops were even:

These laptops are the three manufacturers of large competitors with each other, each model can be found in the vihkajaid lovers. Parallels the automotive world would be like to compare each audit, BMW and Mercedes. Ex-husband bemmi try to say that Mercedes or Audi is better. Competitors, people know how easily mistakes to point out your pet's problems in front of the eye squeezed closed. The same owners also have a laptop, if you have such as IBM's fans, all that is black and square, are often unacceptable.
What is important to the computer?
Computer-satisfaction depends on several levels. What ühejaoks is important, it is not necessarily a second vajadagi. I placed the most important durability and ergonomics, which was followed by the weight, price, battery resistance, interface, sound and wifi. Test we compared it to that time the producers have gone better and much worse. In our view, the least affected by the outcome of the ranking - the speed, the thing which is usually the most emphasis placed on testing. The reason is that since all the laptops were tested, and is highly competitive with each other, then their content is also configurable according to customer requirements. More: the processor, memory, hard drive, chipset and video card is often possible to all producers at the factory exactly the same place. It is therefore pointless to test practically the same quick change things. In addition to the fact that the computer will not notice the speed difference between the work, even if it is different from 10% in some tests. It also did not take into account in the assessment, we look, because it is a matter of taste. HP metallic owner often does not want to think about the ugly black and 15 or more years, and Lenovo-IBM Lenovo computers used by a person disagrees with its sophisticated black notebook in some kind of trinket to change color.
Start testing
The test started with the producers of the selected uuematemudelitega: Dell Latitude E6420, HP EliteBook 8460p and the Lenovo ThinkpadT420.


Dell Latitude E6420




Dell struck the deck of taking us to a barrage of emotion: "Oh my god! Onsaanud what they do now?" Run from the Old and the many beautiful view About Dell business class has become Inspironi rounded corners (the cheapest Dell Series)-like model. The manufacturer to be square with rounded corners better, because they do not cost, durable, and of course look better and be. But the manufacturer has forgotten the fact that the LED-LCD displays are today still means a lot of co-oval, square, and the unused space. The result is that the top of the screen edge of the cover is a staggering 2 cm of free space (screen side), 3 cm (top of the screen) and 4 cm (bottom of the screen)! However, had the same characteristics as the previous model E6410 1.5 cm, 2.2 cm and 4 cm. As a result, the 14.0 "screen of the older E6420 14.1" screen E6410-ie, about 2 cm wider, although the screen itself is 2.5 mm smaller than the diagonal.
Another thing that is immediately visible, the hands, or rather, a greater weight. It appears that even smaller screen E6420 weighs 164 g more than E6410 (both 6cell battery). However, the positive side, we find the cause of weight gain - much better screen design strength is gone. In addition, Dell igipõline "bucket" is now scoring the cover, or the receiving end, since the cover is a thin sheet on top. In previous models had a soft color instead of plastic. So often, we saw a pile of new computers, and scratches at the age of having a computer could look even at the age of 5 seem.


Another positive surprise hit browse the price lists. Fresh Blood for the model with prices starting at EUR 940 (financed under the old 14700krooni). So cheaply has never been sold before the market received a business class models (3-year warranty, WXGA, Windows, and a fast processor). In addition, we like Dell at the keyboard. Ennegi It was good, but now we can say that very good - soft, vintage, buttons, and lack of rattling the exact things that make the best of good keyboard. Fortunately, the keys are modified material. This gives hope that the E6420 does not cost 2kuuga buttons shine as much as 2 years old HP's. The downside is that the keyboard is that the keys are attached at the bottom of a small bead, making cleaning more difficult. At the same time it makes a small dash rounded off by the fact that Dell's keyboard is the only spot you can subscribe to the Estonian capital letters. If you wish, even in backlight - something that is hard to give up, if you exercised.


Dell Displaypordist have given up and replaced it with HDMI. It is gratifying that for home users, but some business users with all the technology on displaypordi, E6420st to give up. It is also not standard USB3 interface, you can request at additional cost, fortunately, DVD-RW replaced frequently. When compared to competitors, even when the screen is all LED WXGA +1600 x900, uses a third-party panel of the Dell tulemusekson that the white is whiter and colors brighter. The positive news About Dell also believes the new fluid drainage facilities - things that were there for 4 aastavanusel Lenovo. Better late than never.






HP EliteBook 8460p



When HP first time we put on the table, sounded a man's mouth: "Wow!" So from the outside, the inside of your computer quite nice, although perhaps a bit too MacBook copy-paste.

HP 6930p model from advertising that they are scratch-resistant casing. It should be noted, however, that 6930p is not very resistant to scratches, but really scratched much less than competitors. So näevadki Elitebookid 2-3 years old when the newly-emerging from the factory. As the 8460p seems to cover the same material, the older models, it is hoped that a strong metal used is the same. Also, HP Palmre (this, on top of which rely on typing hands) is metal - this is for two plus in addition to HP. First, the cost Palmre shine like Dell and Lenovo, and a second computer and draws heat from the metal cooler and quieter. Has been a wonderful soft cover release button, and unlike their competitors, the cover into the metal. Jookul plastic attachments may fluctuate and may be resistant to damage caused thereby shattering the screen. HP is the latest model added to the rubber band around the screen. This reduces the shock on the screen and keyboard dust between the screen when the computer is busy. This bar is also available in Dell, but their HP is a little better.

The touchpad as well as a pleasant surprise, it has been much higher than the average laptop, and it is very convenient to use.

HP is the only test participants who have a USB3, powered eSATA, DisplayPort, and the ID-card reader. Now it is perhaps not a very common USB3, but after 2-3 years is probably difficult to find a USB2 device, but the business-class computers tend to last 4-5 years while life expectancy to rise.
Like Dell, the new HP with a fluid drain. These can be helpful, if someone happens to drinking around the computer to fill up. Based on our experiences we can say that almost every week, no one wants us to save your computer drowned. Often the client sad, because most kallimasi computer - the motherboard to be exchanged around, because the liquid is almost impossible to repair the damage.
On the downside, it is clear that the computer is more difficult than the previous model 8440p gone. Weight gain is a 144G. However, we remain unclear, the increase has come at the expense, because the structure is about as strong as in previous version. Our phone has been sold to 8460p, the BIOS defaults "Fan Always on", we hope that HP will be a future update. Currently, this means that if the power cord is left, undab HP fan constantly trying to keep the system at low temperatures. Fortunately, it is possible to turn it off, but it must be admitted that the BIOS is not exactly the place where the user would be able to spend your time.


If previous HP models looked like Christmas trees in the dark - blue, orange flashing tulukesi full, the model has been lights nõelapea sizes. So even need to be put on the table, to verify that the HDD LED is still flashing, or the computer crashed. Bothered by the fact that the power plug is the left edge of the back, where it remains constant for

In addition to raising questions about the keyboard lights flash. In order to push the brightness of the image sensor (which Dell does not at all), which pops up onto the side of the lamp. We tested this lamp was repeated several times and needed to burn klõpsimist. Fortunately or unfortunately, HP's top-lamp for the biggest thing anyway, so no big loss if it should go for broke.

Put one's head against scratching, as much by its own software, HP is able to put up - a staggering 92GB. Inside the spare partition, in case the computer breaks down, driver and HP's own soft brightness of the screen, security software and the like. Not only that, the more the software installed on your computer is slower and shorter battery each, for example, 128GB SSD is quite a good choice on the computer hard drive, but Windows will remain free to buy the 36GB is still something very wrong.
Unlike About Dell HP and Lenovo have remained faithful to the AMD-ATI video card. Unfortunately, the vain - 3D PC can be 10% said the weaker performance of the battery must be less controversial. Unlike competitors who use Intel-nVidia video cards, the first of which is active in games and other office applications, will use ATI's own power saving technology, which unfortunately is not as good as their Intel graphics cards.
HP is still a major drawback of the price. Local wholesale stores can be the cheapest model available with Windows 7 in 1225 against the euro compared to Dell, it is almost € 235 more expensive. Here we give hope to people interested in the near future Laptopid.ee through the same computer can be available for less than 1000 €.





Lenovo ThinkPad T420



Lenovo out of the box will not we have any emotions, because the computer has the appearance of exactly the same as pre-T410, which was very similar to the T400-ga, which was confusingly sarnaneT61 with that, resembling an IBM T21, which has over 10 years old Thinkpadide ancestor . For some, the appearance of IBM's ugly, very ugly for some. In particular, women rarely seen people who would not start against IBM. However, it must be acknowledged that IBM has done a very good computers and Lenovo computers just good. Therefore, angular body is black probably the most ardent fans, who probably put an end to the Lenovo purchase, if it should ever be silver with rounded corners, or from computer to change. I myself do not agree that business-class notebook should be modest and IBM in particular has always liked my appearance.


Lenovo has remained true to the super-good rubber-coated body, which remains firmly in hand and which can be small scratches on your finger off the spy. For years, the shell can be seen Lenovo's done wonderful things and make a new appearance, such as using gasoline for aviation.

In addition to the previous model's appearance is not seen in the interior side of special distinction. The difference appears only in the fact that the screen is 0.1 "lower. It seems to be the new standard. The keyboard is also a good old Lenovo's. You might think that it takes the shine quickly than L-T410. The same may be afraid of the computer on the corners. Thankfully, only noticeable wear to look far.
Having a computer available is hitting us a pleasant surprise. Weight compared to its competitors in the computer seems to lower. Our mind does not deceive us, 1888g vs. 2170g is the difference between 200g (without batteries).


The difference is so great that we decide to leave the computer attached to the protruding battery cellise 9, even as it is easier for a computer, the test involved six batteries celliste HP and Dell.
Thanks to an extensive test battery, the battery can achieve incredible results, and 12h is a brand new battery (batteries need 4-5x a full cycle empty, to achieve täismahtuvust).


Another pleasant surprise is hitting us carrying out the noise test. Lenovo computer is quieter than its competitors and, most surprising - and cooler! This all shows one thing - a well-compatible components and radikate fans a good layout. Here, too, lies perhaps one reason why Lenovo's design is left unchanged - why change things that work?
Although all manufacturers have a hard drive software shock protection (this is gürosensor which tilt feeling increases the hard disk heads up - as grammofoonil needle), the fact that the majority of cases, where the computer is dropped, they have to have it already up, because who is virtual machine still walks around. Instead of playing a role in shock a lot cheaper and easier to do the trick, what is the use of rubber. If Dell is just the hard drive screws and a rigid frame attached to each hard drive below the shock goes through the rubber, and HP has used very little, if Lenovo has no rigid connection to the computer hard drive enclosure and is positioned between the rubber gasket. This is nicely reflected in the statistics of a hard disk failure. Laptopid.ee perform data recovery in broken hard drives, and it should be noted that Lenovo's notebook hard drives rarely see here. This of course does not mean that Lenovo laptop owner can forget the Backup.

Last remarkable advantage over the other before the computer was that our cabin was Lenovo laptop wifi at most sites. However, it may not yet Lenovo just to show great strength, because in addition to the antenna affects the outcome of the wifi card. They may be 4-5 different from manufacturer to manufacturer. But Lenovo also found a series of mistakes that can scare buyers away, to deduce that the Dell or HP with purchase. Appearance has already been said. Now we know that the weight has come at the expense of savings. In this case, is strongly affected by the screen design, which has been tested that in a comparison of the weakest computers (I am not thinking only of the 2011 models, but all 4 generations!). However, this is for us, repairers, useful, because the screen is physically broken down, and go from 100 to 200 € guarantee a good service. Representation can ask the same thing for € 400-500. Anyway, such a test as the IBM salesmen never did that, went down to the laptop onto the screen and remained healthy, due to possible.
Women are not a target group of relative firm Lenovo. In addition, a rectangular layout is unchanged at Lenovo to use the power of man. Natural button Wi-Fi goes so heavily that I am quite sure that any gel and artificial nails snapped it in half simply by switching.

Lenovo still has not learned the ID-card reader as standard equipment to include. Fortunately, this can be added later, but in this case is asked in addition to about 100 €.
T420 is a computer that can not be any trick USB3 külgepookida. Fortunately, there is attached to a computer powered e-Sata, välisedkõvakettad where you can connect, and even 300MB / s data transfer rate to enjoy.




Test table, and how we tested.

Test table can be found here LINK

We put a table in the manufacturer's data and our assessment of the three 5-point scale (1-min 5-max).

PRICE
Laptopid.ee price in 2011 is a price for the end of May. Computers as we tried to find the same configuration and price, HP's got much more expensive, unfortunately.

Factory Information
Sandy Bridge processors are all computers based on Intel technology, the latest version: i7-2620 3.4GHz processors with two cores and 4MB 35W cachet. Dell's got a i7-2720 3.3GHz 4 core, 6MB and 45W max power consumption cachega processor. The manufacturer of processors involved in the comparison test can be found here But as mentioned, the speed test results did not influence the final assessment, as well as provide a faster processor, and HP Lenovo.

RAM memory, which all have DDR3. MHz, the table was not going to bring, as well as all producers have the same model vary. In addition, the memory speed is not noticeable from a small difference in the work.
The screen is all 14.0 "1600x900 LED. But you should not forget that in 9 cases out of 10 have a higher resolution screen for better image than a smaller one, ie choosing 1280x800 screen picture is probably worse. Also, use a different region and keeping the same exactly the same patterns different types of screens. This time, though Dell was noticeably better screen, but the second half of the year, after commissioning the factory configuration of a computer can get the same third-party panel, and the picture is just a second.
Video card was a Dell and Lenovo nVidia NVS 4200, which was supported by the Intel 3000 graphics card at times when speed is needed, and it is essential to use a quiet computer, and a long battery time. HP uses AMD's ATI 6470M-i. However, it should be noted that äriarvuti for 5500 points in 3D Mark 2006 performance, until a few years ago aspired to the top playa laptops.
The hard drive is also the thing that all of the same type may be different on your computer, and a 160GB HDD is generally a weaker result, the 500GB. The difference is particularly well observed, with the monthly võrrdelda SSD.
Weight has been taken from manufacturer's data. As you can see, is a manufacturer of gravity + /-500g-face lie to the consumer, it's a hidden "from ..." want, or you will be considered for any additional PC cards, etc will be the smallest of the battery.
Battery weight and capacity indicates the battery is effectively done. Wh shows that when the computer to 1W per hour, you should 55Wh battery in 55 hours, tested that was consumed by computers minimaalseimalt 8-12W, while the full power of the processor, Dell is able to consume only 45W.
Depth, width, thickness as well as the manufacturer's data. They measured the above, the manufacturer is lying in that spot a little bit, but the difference between just a few mm.

PORTS
USB3 onedasiarendus USB2-ie, after the ~ 10x faster (ie about 300MB/sandmeedastuskiirusega to be helpful, such as copying movies to 1080p and 3D).
Powered by e-SATA is an interface that is present on all hard drives, only to have e-SATA hard drives and separate power cords.
DisplayPort is designed for an image from your computer monitor into a TV or projector to send, it allows for better quality and higher resolution than HDMI.

Audio line-out Dell and Lenovo have been one of the slot. This means that the microphone-headphones were the two pre-wired, but now they must exchange a circle. However, the fewer wires the better.
Production of the market, the computer shows the first time, business-class models, the CA1-year life cycle - when it is completed, the new model.
Links from the manufacturer takes the data on your computer.

DETAILS OF TESTS
Weight. Meiemõõtsime weight removed from the computers, because computers can buy a business class 4, 6 and 9celliste batteries. Used the kitchen as a measurement of weight (+ 5gr).
Chargers, most manufacturers have two versions of 14 "laptops - 65W and 90W, goes lower than Intel's more powerful video card and Nvidia / ATI video card.
Perfomance index shows Windows 7 to Windows built-in test results - processor, memory, graphics, games and hard drive. This is not exactly the most accurate test, however, gives an overview, especially in older models for comparison.
Speed ​​games. 3D Mark 2006 is a program for testing graphics cards. Laptops achieve top-class gamers in more than 20 000 points, while 17 "and weigh 5kg +. More details on the test table 3d brands can be found here

3D brand of heat at the end. Computer mõõtsimenatukene heat before the end of the test, all the laptops had been on the table before starting the test at least 1 hour. The results measured the center of the keyboard and the left-paremaltpoolt Palmre and bottom of the same locations.

The sound quality of audio shows from a distance of 30cm, sitting at the computer. Table is from the sound of our opinion. Pulled down the score as always, the speakers were located under the front panel of the computer. In this case, the sound is reflected off the table and is distorted
The sound from 2 meter to measure the sound turned up and listened to 90% at a distance, imitating such a meeting or presentation, music and friends.
We tested the strength of the structure housing the computer and it twisted the arms of the strong force. This test would probably be a lot of non-äriklassisülearvutid easily broken.
Screen test vastupidavuspaindele twisted my screen from different angles, as well as tested the LCD panel and cover the distance between the pressure immiteerides after the withdrawal.

The cover material is a metal from any computer, Lenovo is pelae plus you put a layer of rubber. It also has a metal frame with slats of all business-class manufacturers sülearvutiteljuba long been inside, even when placed onto the plastic, and plastic at first glance seems to be a computer.
Palmre material significance will emerge over time, namely the plastic will take a smooth and begins to shine, metal generally does not change its appearance.
The screen is a confirmation of assistance to transport your laptop. Car passenger's seat vedeledes cheaper laptops will bray, while he himself spending ugly. It is also convenient to go to the proper approval and closing.

Drain the fluid will greatly benefit if someone something other than laptop drives and there is a rule, the more holes the better.

Closed computer dust cover is a small strip of rubber in recent models of the screen, which prevents the dust between the keyboard to get into.
Rubber feet must be such as to remain firmly under the floor to hold the computer firmly attached to the table.
HDD padding is the padding around the physical hard drive that can shock your computer to save the data.

ERGONOMICS
Tested by pressing the buttons on the keyboard keys move.
Quick typing keyboard buttons klõbinat tested.
The screen of the straight and looked at from different angles.
Wi-Fi mark catching was the largest and strongest most wireless broadcast networks have found a computer.

FURTHER TESTS FOR NEW MODELS
HDD full when new liitsime and subtraction, a lot of factory partitions, windows and the software supplied by the manufacturer shall take a new computer room.
Battery life 100% -> 5% of the computer loaded the battery fully charged, I turned to a dark screen brightness, wifi and bluetooth off maxbattery setting. As the batteries were brand new, the result after 4-5 charging ~ 5% increase.
3DMark tests measured the noise in the middle of the computer side (at the openings in the fan), and sitting down, above the ears. The normal operation of computers is much smaller and should have gone to measure the sound-proof room.

TEST WINNER
Our winner, this time turned out to Lenovo T420. The second place was the HP 8460p and the third must accept Dell E6420.
Lenovo earned first place in the low weight, good battery life, low noise and the appearance of a solid. Dell was the last because the weight is a big, ugly, and many believe that the appearance of large dimensions. HP remained in first place on a better price and lighter weight.
However, it must be admitted that we were confident at the start of the test, the Dell, and forlornly põrub will fight for first place in the HP and Lenovo, Dell showed the test had identified several positive aspects for the choice was a difficult and contentious pikke. In fact, all three models tested that was a very good computers.
However, do not believe that the ancient headlines Dell's supporters would now buy a Lenovo, but perhaps there is some hesitancy present, acquire new business-class model to test the person making the choice easier.

As the story was much more than expected, we decided to test divided into two. The second part will appear in the near future - there can be read, which is the better models from different years are gone and the winner of each vintage.
In the meantime, those interested can look great just looking at the table with the current test comparisons, avutite LINK

Part II is here Link
