Lenovo's 14.1in. ThinkPad T61 shaves a few millimeters off the company's more mainstream R-series notebooks, but still boasts the same, solid ThinkPad DNA along with IT-friendly features by way of Intel's new Centrino Pro platform.

Despite the new technology, this is still largely the same black, boxy ThinkPad you've come to know and perhaps love. However, Lenovo is starting to add more mainstream features such as optional webcams and media card readers. It's still pricey when configured for power users, but the typical excellent ThinkPad build quality makes this a system that should enjoy a long lifespan.

Like the ThinkPad R61, the T61 features a wide-screen display, which is fast becoming the norm even in business-minded notebooks. The chassis itself has been reinforced with a new internal roll cage, replacing the traditional solid magnesium alloy cover. The slightly concave roll cage, hidden under a composite cover, protects the LCD, while helping Wi-Fi reception, which Lenovo claims can be negatively affected by an old-fashioned full magnesium alloy cover.

We're also firm fans of Lenovo's extremely small AC adapters. After all, there's little point in carrying around a lightweight notebook if all the extra room in your bag is taken up by a huge power brick. Lenovo's two-prong adapter, in contrast, weighs around 225g and the brick itself measures just 10.2cm long by 3.8cm wide by 2.5cm thick.

The road-ready design includes sturdy steel hinges and a shock-mounted hard drive. The ThinkPad keyboard is still one of the best notebook keyboards available, offering an extremely comfortable typing experience. The T61, in true Lenovo fashion, also features both an eraser-head pointing stick and a touchpad, each of which has a set of mouse buttons (the top set includes a scroll button in the middle). Above the keyboard are three handy volume buttons — the extent of the system's dedicated multimedia controls — and a blue ThinkVantage button, which summons Lenovo's helpful preinstalled support-and-configuration utility. Our T61 review unit was missing the optional webcam found on the R61.

The 14.1in. wide-screen LCD display offers a 1,440 by 900 native resolution, which is a bit finer than the 1,280 by 800 resolution commonly found on 14- and 15in. systems. Text and icons are highly readable and the screen has a matte finish, which we generally prefer to the glossy screens found on many consumer notebooks.

The ports and connections on the T61 are in line with what you'd expect from a mainstream business notebook, although we'd have liked to see one more USB port and an S-Video output. The ExpressCard slot can be swapped for a media card reader in Lenovo's online configurator for no extra charge. Our review unit didn't have Bluetooth (which is an available option), but it did offer a built-in 802.11n antenna, for the very latest in fast Wi-Fi connection speeds. You will, of course, need a Draft 802.11n router to take advantage of it.

One major feature the Centrino Pro ThinkPad T61 has over the Centrino Duo R61 is the inclusion of Intel's Active Management Technology, where your IT department can remotely fix, update or even recover your system after an OS failure, if you're still connected to your company network — even if the system is in sleep mode. It's a boon for large, enterprise organisations because your IT staff can push updates to all of the systems on your network at once; it saves you from having to physically visit offices or cublicles where the PC or notebook isn't running.

The ThinkPad T61 can be configured with any of Intel's Santa-Rosa-compliant Core 2 Duo CPUs, from the 1.8GHz T7100 to the 2.4GHz T7700. Our review unit included the middle-of-the-road 2.0GHz T7300, along with 2GB of RAM (expandable to 4GB) and a 100GB 7,200rpm hard drive. You can bump the hard drive up to 160GB, but the larger drives run at the slower 5,400rpm speed.

Like the other Santa Rosa systems we've tested, including the Gateway E-475M, the T61 offered excellent performance, but fell slightly behind its less-expensive cousin, the ThinkPad R61, because our build of that model had a faster T7500 CPU. It was also slower than the non-Santa-Rosa ThinkPad T60, a long-time notebook favourite. The T60 has a slightly faster, although older, T7600 CPU, showing that the new Centrino Duo platform won't drastically change your computing experience. We expect to see larger performance gains once 800MHz memory is available for notebooks later in the year.

Overall performance differences were minor between the largely similar Gateway and Lenovo Santa Rosa systems we tested. In anecdotal testing, the T61 felt fast and was stutter-free, even while multitasking — but we'd expect nothing less from any recent notebook.

Although the 128MB Nvidia Quadro NVS 140M graphics card is an option in both the T61 and R61 ThinkPads, our T61 used the integrated Intel X3100 GPU, which Lenovo says will give you better battery life than running a high-powered graphics card. The system ran for an impressive 2 hours and 29 minutes on our DVD battery drain test, using the included six-cell battery, which sticks out a few inches from the rear of the system. That's a little more than 20 minutes more than the R61, which has the discrete video card option. Bear in mind that our DVD battery-drain test is especially gruelling, so you can expect longer life from casual web surfing and office use.

Lenovo provides a three-year warranty, which is standard for business notebooks. You can choose from several different warranty extension options. The preloaded suite of ThinkVantage applications helps users troubleshoot problems; the company's support web site also has an extensive support section.
