Using Oxelon Media Encoder, the T420 transcoded a 114MB MPEG4 to AVI in 43 seconds, 15 seconds less than the thin-and-light average, and on a par with the Toshiba R840 (41 seconds) and the HP 8460p (42 seconds). That's a rate of 27.5 MBps, a little higher than the 26 MBps category average but well behind the 34.6 MBps provided by the Dell Latitude E6420 and its 7,200-rpm drive. The drive took a modest 3 minutes and 5 seconds to complete the LAPTOP File Transfer test, which involves copying 4.97GB of mixed-media files.

The 500GB, 7,200-rpm hard drive booted into Windows 7 Professional in a speedy 48 seconds, much faster than the 65-second category average. On PCMarkVantage, which measures overall performance, the T420 scored a strong 8,197, much higher than the 5,596 thin-and-light notebook category average, the 7,728 turned in by the Toshiba Tecra R840, and the HP EliteBook 8460p (both have the same Core i5-2520M CPU).

With its 2.5-GHz Core i5 CPU, 4GB of RAM, an Nvidia NVS 4200M graphics chip, and 7,200-rpm hard drive, the ThinkPad T420 was strong enough for anything we threw at it, from playing 1080p video to spreadsheet crunching and light gaming.

The software also allows you to configure the dual-array microphones for a single voice or group chat. Lenovo's conferencing software features a unique keyboard noise suppression feature that, on our tests, completely muted the sound of our typing as we chatted on Skype. However, like with many other webcams, our face appeared shadowy if there was a bright light source directly behind this occurred when we tried snapping a photo while sitting in front of a window with sunlight coming in. In our dark living room, fine details of our face were visible when we snapped a picture at 1280 x 720 and chatted on Skype in standard def.

The 720p webcam provided sharp images even in low-light situations. Considering that we've been seeing notebooks with USB 3.0 for over a year now and that Lenovo offers USB 3.0 on many other ThinkPads (the X1 and W520, for example), this is a pretty glaring omission. Conspicuously absent are USB 3.0 ports and HDMI-out, neither of which are even available as options. The left side houses VGA, DisplayPort, Ethernet, and one more USB port (for a total of four). On the back are a FireWire port and a powered USB port that allows you to charge devices with the system off. On the right side are an Express Card 34 slot, a 4-in-1 memory card reader, a USB port, and a USB/eSATA port. The ThinkPad T420 has plenty of connectivity options, but it's missing a couple of the obvious ones. We could even make out a solid separation of sound between the speakers, which sit on either side of the keyboard. Whether we were playing Kool and the Gang's jazz-oriented 'Summer Madness,' the bass-heavy 'Between the Sheets' by the Isley Brothers, or Motley Crue's guitar-laden 'Looks that Kill,' sound was accurate and loud enough to fill a medium-sized room. While not as high fidelity as audio-focused consumer notebooks such as the Dell XPS and the HP Envy series, the Lenovo ThinkPad T420 provides surprisingly good music playback. We highly recommend the 1600 x 900 panel, a $50 option, because it shows a lot more of your favorite web pages and documents without forcing you to scroll. However, when we streamed a 720p Flash episode of Fringe from Fox.com, the edges of objects seemed a little pixelated, perhaps because the screen had a higher resolution than the video.

When we watched a 1080p QuickTime trailer for the movie Point Blank, images were sharp and motion smooth with viewing angles solid up to 45 degrees to the left or right. The 230-nit, 14.1-inch matte display provided sharp images and plenty of desktop real estate thanks to its optional 1600 x 900 panel. We consider temperatures below 95 degrees comfortable. After streaming video for 15 minutes, the touchpad measured a frigid 82 degrees, the keyboard an icy 81 degrees, and the bottom a cool 87 degrees Fahrenheit. The ThinkPad T420 stayed pleasantly cool throughout our testing.
