Lenovo ThinkPad X1 Carbon Ultrabook Review

Display Quality

I don't know about the rest of you, but I'm pretty happy to be getting notebooks in for review that don't have lousy 1366x768 panels. I desperately want to believe this is the direction the notebook market is heading in, though a pair of $1,500+ notebooks don't really constitute a trend, and I'll be a lot happier when $600 notebooks have gotten past 1366x768.

The Lenovo ThinkPad X1 Carbon employs a 14" 1600x900 display standard; Lenovo lists it as "wide viewing angle" but it's still most definitely a TN panel. That said, viewing angles are definitely good, and it exhibits none of the "no sweet spot" issues that plague lower quality displays. Lenovo's pseudo-glossy finish isn't as brilliant as typical glossy finishes are, but it's also not as reflective.

The X1 Carbon's display quality is acceptable, but take a look at the contrast graph to get a really good idea of how much of a difference spending just a little more on a display can make. The HP Folio's display has such horrible black levels that its contrast ratio is actually lower than its maximum brightness. Meanwhile, the X1 Carbon has a display that's both lovely and functional, and 1600x900 is about right for a 14" panel before you get into having to mess with the broken dpi settings in Windows.

Battery Life

While most of the Lenovo ThinkPad X1 Carbon's user experience is at least solid, battery life is one area where it falls horribly short. That Lenovo doesn't offer any extended battery option of any kind turns out to be a major problem.

The X1 Carbon's battery life isn't horrible, but it's way out on the bottom end of competitive. Dell's two "prosumer" XPS notebooks both offer superior efficiency and running time, and the XPS 13 in particular can offer you a stellar 1080p IPS display in the process.

Heat and Noise

Sporting a larger chassis than most Ultrabooks, the Lenovo ThinkPad X1 Carbon is able to do a fantastic job of keeping the ultra low voltage Core i5 running cool. There's definitely a high-pitched whine to the fan when it spins up, but it's not especially loud under extreme, sustained load.

Thermally the X1 Carbon is almost boxing under its weight. None of the surfaces of the chassis get hot, and it's actually difficult to get either core of the i5 to break 70C. I think you could probably make a case for using a higher powered CPU in the Carbon's chassis, but I'm honestly happy just to see a notebook that not only doesn't have heat issues, it doesn't even flirt with them.
