The U772 is clearly on the high side of Ultrabook pricing; it starts at higher than what most Ultrabooks sell for. That said it has some impressive specifications; the Intel Core i7-3667U (a $150 option) is the fastest dual-core processor available in an Ultrabook and the included 128GB Micron C400 Solid State Drive ($230 option) is blazing fast. Everything else on our review unit is standard. The base customizable U772 is equipped with a 320GB hard drive and an i5-3427U dual-core processor. I think the SSD is almost certainly worth the upgrade (no noise, less power consumption and eons better performance vs. a hard drive) though the i5 processor is more than sufficient; chances are the i7's extra power will go unnoticed and $150 is a lot of money for such a moderate increase in performance.

The U772 packs some business friendly functionality I have not seen on many Ultrabooks, namely Intel vPro remote management technology and a fingerprint reader. Also note the U772 comes standard with Windows 7 Professional; Home Premium isn't even an option. Lastly I'll point out the standard Bluetooth and better-than-average Intel Centrino Advanced-N 6205 wireless card.

The U772 performed admirably in our benchmarks; it is more than capable for everyday tasks, even the occasional use of Photoshop.

Heat and Noise

There's a single cooling exhaust vent on the left side of the notebook. The good news is that most of the time it stays off; this notebook produces little heat except when watching HD video. The fan gets rather noisy when it turns on however; it has a slight whine and can be heard across a medium size room. The left side of the notebook around the fan gets not quite hot but close to it. I can't say I'm impressed with the U772's thermal management.

Battery Life

I measured six hours, 14 minutes of battery life during our standard battery run-down test (Windows 7 Balanced power profile, 70% screen brightness, wireless active and refreshing a web page every 60 seconds). This is about in the middle compared to other Ultrabooks we've reviewed; the Dell XPS 13 for example achieved 7:23 but the Samsung Series 9 just 4:55.
