IBM Thinkpad T42 Review -- T42 Good for Gaming?


I received the IBM ThinkPad T42 (2379R9U) notebook in the mail last week along with all the accessories After powering the notebook up and going through the initial boot process, I was immediately impressed. I remained impressed from that time on, and...

After looking at every possible notebook I came to the following conclusions: if I went with HP I might have achieved "OK" performance, but poor build quality, as many readers of this website are aware about. Dell notebooks in my opinion just look...

IBM ThinkPad T42 with Biometric Security Review (pics, specs)


IBM can unjokingly claim that its middle name is Business, and that's what they're all about when it comes to security. The latest ThinkPad T42 refresh features biometric security that is squarely aimed at business buyers. Fingerprint security...

The best keyboard around, combined with TrackPoint navigation allows for easy use and input Tough case (titanium reinforced plastic) and rugged design, yet still relatively thin-and-light. Good bright screen. Using finger scanner as a substitute for...

Pricey, you'll pay $2,000 and up for a good configuration No FireWire port or media card reader, only two USB 2.0 ports Battery life suffers with the 15.0-inch screen, expect 3-hours or less if screen is at full brightness and wireless is on

If what you are looking for is a highly durable laptop, with great performance, great service and great usability then the ThinkPad T42 is for you -- if you're willing to pay the price that is. This laptop is particularly good for business related work...

IBM's new ThinkPad T42, is a healthy 5.4lb boy!


Okay, we don't really know if it's a boy-it can be really hard to sex these things sometimes-but what we do know that is that the ThinkPad T42 has got WiFi and Bluetooth, a relatively lackluster 15.1-inch screen, up to 2GB RAM, the trademark IBM...

ThinkPad T42 Notebook


IBM creates another fast, well-equipped business notebook.

IBM's latest slim corporate notebook has the same great keyboard and expandability as its predecessor. The ThinkPad T42, a peppy performer, offers a strong value for $2299. Business application software is not included in the price

Great value; excellent performance; bulletproof IBM design; Gigabit Ethernet; long battery life; great service and support.

Lacks FireWire; no flash media slot.

IBM ThinkPad T42 2378-EXU


Business users take note: IBM has added a 15-inch display to its flagship ThinkPad T42 line. For an additional $50, you can get even more of the T42 you already know and love, which includes 15 percent more screen space—if you don't mind a bulkier...

Gorgeous 15-inch display. Same great fit and finish, manageability, and protection of other ThinkPads

Below-average wireless throughput. Marginally heavier, one-quarter bulkier than the 14.1-inch T42

IBM ThinkPad T42


The IBM ThinkPad family has always been highly regarded for its reliability and dependability, and their keyboard feel is unmatched among its peers. ThinkPads have also had the rap of being pricey, so we were surprised to see that... click here for

Sharp screen; great ThinkPad keyboard; one-button access to self-serve help and diagnostics

Getting a wireless connection profile to work can be tricky

We couldn't have guessed the ThinkPad T42 would be the value leader in the crop of new Dothan-based portables. It's well-priced for a system of this caliber, but note that others deliver better performance and more features (albeit for more money).

The T42 is the Place to Start


When I set out to research a new laptop, I quickly had the reaction that many in my position probably do: nausea. There are so many laptop brands, so many proprietary technologies, so many marketing ploys - it's a thicket. The chain stores (Best Buy...

Powerful, Relatively Light, Good Battery Life, Good Value, Amazing Engineering

No dedicated 'Windows' shortcut key. I hate that!

Laptops are portable, they're stylish, and let's face it: the opposite sex will think you more sophisticated when you're suavely tapping out your latest blog entry at the coffee shop. Okay, that's probably not true, but they are fun to have for both...

Become more productive by taking your digital life with you. Whether for business or leisure, laptops allow you to carry your information with you, all in a lightweight and compact design

Product Specifications

The unique Embedded Security Subsystem, a ThinkVantage Technology, is available on select models.

Rapid Restore PC, another ThinkVantage Technology, is preloaded - giving you the power of a one-button recover and restore solution to save time and frustration.

This can improve signal reception whether you choose models with integrated 11a/b Wi-Fi wireless, Cisco Aironet Wireless 802.11b or when used with compatible options on wireless-upgradeable models. Choose ThinkPad T40 notebooks - the perfect balance of performance and portability.
