Laptop new Model by Lenovo: T400 Review

Posted by: admin  :  Category: Computers, Uncategorized

The Lenovo ThinkPad 𔦰 proved to be an exceptional 14″ business notebook, giving almost unheard-of battery performance under modest running conditions. Nearly 10 hours of runtime with the extended battery easily puts this notebook into the all-day computing category. System performance with the Intel 󏗸 processor and ATI 3470 graphics was great, handling everything we threw at it, even some video games. The 𔦰 is not without its flaws though, having a decent amount of keyboard flex and a keyboard light that blinds you. Even with its flaws, with a starting price under $1,000 this notebook easily outperforms any other computer in its category.

• 10 hours of battery life with the 9-cell battery!
• Very bright LED backlit LCD
• Under normal conditions is very cool and quiet
• Hybrid graphics that let you switch between great 3D performance or great battery life
• Keyboard flex in a ThinkPad … the end of an era.
• Keyboard light that blinds you instead of just illuminating the keyboard

Performance

Lenovo ThinkPad T400 came with the Intel T9600 processor, clocking in at 2.8GHz, and jammed packed with 6MB of cache. For graphics, Lenovo included an ATI Radeon 3470 video card with 256MB of GDD̷ memory. A speedy 160 GB 7200 RPM hard drive was also included, which helped applications load without much lag. This notebook was outstanding for day to day use, and had enough power to handle most games around the office to kill some time. Half-Life 2 in native resolution (1440×900) kept above 30FPS even in heavy action scenes. Portal was another favorite that worked very well at native resolution, keeping framerates above 40FPS throughout most of the game.

For users who don’t wish to have as much 3D acceleration (or power consumption) during day to day work, you can switch between the Intel X4500 integrated graphics and ATI 3470 dedicated graphics. This switch can be made on-the-fly without a reboot. Not using the dedicated graphics resulted two hours of additional battery life.

wPrime is a program that forces the processor to do recursive mathematical calculations, the advantage of this program is that it is multi-threaded and can use both processor cores at once, thereby giving more accurate benchmarking measurements than Super Pi.

Battery Life

To get 10 hours of battery life from a notebook this size, most people think you would need a huge battery attached to the bottom of the case, another battery taking the place of the optical drive, and a big battery sticking out the back. With the T400 you can reach 9 hours and 41 minutes with the wireless enabled, screen backlight at 60%, and the laptop in integrated graphics mode using only the 84Wh 9-cell battery. In this situation the notebook is only consuming roughly 8.5 watts of power. In dedicated graphics mode under the same settings battery life falls by exactly 2 hours down to 7 hours and 41 minutes, and power draw increases to 10.5 watts. The 6-cell battery managed 6 hours and 4 hours and 28 minutes respectively.

Ports and Features

Port selection rates average on the T400, with 3 USB ports and no digital video output. You do have VGA, but it is not the best option if you want to hook the notebook up to an HDTV. As mentioned about in the Build and Design section, the T400 with the SD-Card reader option nixes one the PC-Card slot. For those thinking about using legacy external cards, you may want to reconsider that option.

One feature that has been on ThinkPads almost forever is the ThinkLight, which is a small white LED located above the screen that illuminates the keyboard. On every other model we have reviewed that has this light, it works as intended and gives a little light on the keys. On the T400 the shroud in front of the LED isn’t big enough, and the end result is a light blinding you. Your night vision is taken away and in the end it is a useful feature turned worthless by lack of proper design. Not exactly sure how it made it past quality control, but unless you have the screen tilted forward to an extreme degree you end up as blind as a bat.

Heat and Noise

The cooling system seemed greatly improved over the prior generations, letting the notebook run whisper quiet and very cool to the touch under most circumstances. I say most, since gaming did seem to make it run on the high side. When not gaming, one thing really working towards the system temperatures advantage was the very lower power consumption. Consuming almost half the power of the previous generation really helped reduce overall temperatures.

Google Chrome

Why Google Chrome ?

Three reasons why it matters3. Because Windows needs more competition
Nearly two decades after Microsoft Windows conquered the PC, very few real challenges have been mounted against its dominance. Long-time rival Apple Macintosh has recently had a resurgence, but it’s still hovering at less than 10% of the total market. This market is ripe for innovation and a new competitor. In many quarters, Windows fatigue has set in, especially in the notoriously price-conscious consumer market and in light of the Vista debacle. The virus, spyware, and security troubles of Windows are its biggest weaknesses and Google is wise to target those soft spots with Chrome OS.

2. Because Chrome OS will be cheap
Google has confirmed that the Chrome OS will be open source and will not have any licensing fees. That will enable Chrome OS-based netbooks to be cheaper than both Windows-based netbooks and ARM-based smartbooks from Qualcomm. Plus, once we start talking about nettops, it’s entirely possible that we could see a $100 PC (without monitor) running the Chrome OS.

1. Because it’s from Google
Google is the 800-pound gorilla of the Internet. Because of its brand strength and star power, it’s always a big deal when Google enters new markets. Nothing that Google does will go unnoticed or fail simply because it didn’t get enough exposure.

Four reasons why it’s virtually irrelevant4. It’s running Linux
So is 2010 going to be the year of Linux on the desktop since Chrome OS is based on Linux? Every year for the past decade was supposed to be “The Year of Linux on the Desktop.” It hasn’t happened and it’s not because it was an idea ahead of its time or it needed a stronger champion. The mass market has rejected Linux on the desktop. Linux is nothing more (or less) than a niche OS loved by a loyal group of highly-technical users. Even Google can’t change that, unless it’s prepared to write Linux device drivers for all of the world’s printers, digital cameras, keyboards, and mice.

3. It’s too late
By the time Chrome OS is released, Windows 7 will be everywhere (at least in the consumer market) and Mac OS X will be faster and simpler with the release of Snow Leopard. If Google really wanted to make a powerful entrance into the OS market, the time to do it would have been mid-2007 when it was obvious that Windows Vista was a failure and it would take Microsoft a couple years to fix it. The opportunity for an OS to make a major impact on the PC market has passed. The OS just isn’t that important anymore. Windows and Mac both do a pretty good job of making the OS get out of the way as quickly and easily as possible. Chrome OS probably won’t be able to do that because it will start out with massive device driver incompatibilities with PC accessories.

2. Google hasn’t proven it can build an OS
Google hasn’t exactly knocked anyone’s socks off with Android, its mobile OS. While Android has potential and still has time to develop, it feels like beta software in a market that demands greater “finish” and attention to detail (see iPhone and Palm Pre). Plus, Android itself was originally touted to be a netbook OS. Therefore, the release of Chrome OS is a de facto indictment against Android, despite the fact that Google executives have tried to downplay it. Maybe Google has realized that the Java software sitting on top of a Linux codebase in Android would have severe performance limitations on a PC. Whatever the case may be, the fact that Google will have overlapping netbook operating systems does not inspire a lot of confidence that Google knows what it’s doing in the OS market or has a sound strategy.

1. It’s limited to netbooks
So here’s the skinny on netbooks. They have two great features: They are small and cheap. They also two big drawbacks: They are terrible and a lot of consumers regret buying them (verified by a recent NPD survey). The consumer backlash against netbooks has already begun and by the time we see Chrome OS netbooks from Google’s hardware partners in the second half of 2010, the netbook phenomenon will either have retreated into the background or morphed into something better. And then Google will have to scramble to make Chrome OS available on a wider variety of notebooks computers, as well as on nettops.
