Lenovo ThinkPad X1 Carbon Ultrabook Review
by Dustin Sklavos on May 15, 2013 12:01 AM ESTSystem Performance
By this point, Ivy Bridge is old hat. We have a fairly common ultra low voltage Intel Core i5 and a speedy Intel SSD; no dedicated graphics required. This isn't Lenovo's fault, it's just the result of catching a product this late in the refresh cycle. Performance testing winds up being more of a sanity check to make sure everything is running smoothly.
That said, I did run into a hiccup during testing. In BIOS, the CPU was set to "Battery Optimized," which locked it at 600MHz. The setting labeled "Maximum Performance" actually just allows the CPU to turbo the way it's been designed to, and I feel it's worth pointing out that the "Battery Optimized" mode actually had worse running time than "Maximum Performance." This is easy enough to explain; modern processors are designed to finish tasks and go idle as soon as possible, so capping the CPU's top speed prevents it from doing exactly that and forces it to work longer.
System and CPU testing yields absolutely no surprises; the ThinkPad X1 Carbon's i5-3427U falls in line exactly where it's supposed to.
Graphics results are more of the same. The HD 4000 in the X1 Carbon puts in a strong showing (comparatively) in 3DMark's Ice Storm test, but it's basically still an Ivy Bridge HD 4000.

Lenovo needs to fork their Thinkpad line into two, one for enterprise (what "Thinkpad" used to be) and one for consumer/prosumer. I thought the "Thinkpad Edge" branding would have been good for this. Taken as such, this should be called the "Thinkpad Edge X1."If they want to keep using "Thinkpad" the way they have been the past few years, why not separate out a line called "Thinkpad Pro" for diehards like me? Give us an X series, a couple T series, and a workstation replacement W series. Give us the keyboard back, magnesium rollcage design, IPS displays, charge $1800 for it. Roll back the numbers a bit; I want mine to be called Thinkpad Pro T30s. It has Haswell.
A guy can dream...

Dustin, I have a suggestion.Anandtech is a general hardware site, so you don't have to review all laptops. How about just making it a rule that you unless special circumstances are in place simply won't review laptops with 1366x768 or lower resolution?

Stay Away!I purchased 2 of these for my company (about 3 months apart.)
Normally I would never buy a non-upgradable & difficult to service laptop for the company, but what management wants . . .
The newer of the two laptops had its battery stop holding a charge after about 6 months of use. The older unit's battery stopped holding a charge 5 days after the 1yr warranty expired. Lenovo will not replace it and referred us to a local 3rd party service center (who wants ~$600).
I can't speak on the newer unit, but the older unit that just crapped out shows 84 cycles on the battery. The only good thing out of the whole mess: Management will stop arguing with me when I say no (for now at least). A T430S is close in weight and size, and lacks the repair / mid-cycle upgrade headaches that are sure to happen in any environment.
How they every marketed this to businesses is beyond me!
PS: Only good thing about Lenovo (besides the T series) is they document the hell out of everything. Replacing the batt. will be a headache, but is doable. Anyone who's repaired a laptop shouldn't have to much difficulty, and the service manual tells you exactly what components to remove to get to it.

This is the kind of info I was looking for. Thanks.I am still waiting for something that is closer to my T60 notebooks with the 4:3 SXGA+, nice keyboard, TrackPoint, and runs Linux, though some compromise seems necessary. Perhaps the next version of the Chromebook Pixel.

Nobody is making 4:3 screens. 16:10 was fine... but now its 16:9... it sucks. And when I'm ready for the next monitor upgrade... it will be 16:9 ugh... but it will be at least 2560x1400 res (I'd like for it to be 2560x1600 thou)... and be only 27" to get the higher dot pitch.jmsb - Saturday, May 18, 2013 - link
"stopped holding a charge 5 days after the 1yr warranty expired"The x1 carbon has only been out since August 2012 - 9 months at best.

There are other Carbon series notebooks.eviljav - Thursday, May 16, 2013 - link
The keyboard layout is terrible. The should put page up and page down back in the top right corner, in a block with delete, home, & end.CrazyElf - Thursday, May 16, 2013 - link
Yeah, it's really the price that kills this laptop. It's not a bad laptop per se, but for the money ... it's really hard to justify.One huge advantage I suppose of getting this over the Mac is that laptops like these are more durable - Lenovo Thinkpads in general are well built (although their cooling solutions could be better). I think they do pass MIL-SPEC 810F (not 100% on this one).
Battery is just so, so. And for the price they ask, I expect a better LCD panel.

I wonder if they cheaped out on the battery - not able to hold a charge after only a handful of cycles. This is an example of saving a few dollars here and there for a laptop that costs over a thousand dollars.
