Battery life is decent but by no means stellar given the rest of the Ultrabook class. The battery is a 54Wh 6-cell Li-ion (not lithium polymer, it should be noted) pack of the sealed-in, non-removable variety. Our battery life testing showed a hair over six hours in the internet benchmark and an idle life of close to eight hours. You can reliably expect at least 5.5-6 hours of runtime in light usage scenarios, about average for 14” Ultrabooks but well behind class leading 13”ers like the old Zenbook UX31E.

As I go through more Ultrabooks, I’m finding that the larger 14” and 15” models are not nearly as power efficient as the 13” Ultrabooks, so you find many more data points in the 4.5-6 hour range than in the 7-9 hour range that most of the 13”ers fall in. It makes sense, given the larger and more power-hungry display panels (which easily account for 30-40% of power consumption in our web-browsing test), but unfortunately, manufacturers aren’t putting in larger batteries to compensate. The U845’s battery is a meager 4Wh larger than the 13” Zenbook and Zenbook Prime. Also not helping here? The list of Toshiba services that drain even more power should you not disable or uninstall them first (I uninstalled Norton and ran the battery test with all unnecessary and easily killable processes disabled).

    At $600, I can almost forgive the bad screen, but the fact that cheaper tablets are shipping with vastly superior displays want to make want to go to a Best Buy, and smash all their laptops (with eww displays) with a baseball bat.

    the funny(actually it is ridiculous) thing is that a smartphone at this price range has a 720p screen that costs about 30 $(not retail).
    imagine how people would react to a product that has 4 of those screens, even if there are bezels in the screen and give you a 1280+1280X720+720 screen, that's a 2560X1440.
    we have seen many crazy staff going on with the computers, that's one that is going sell like hell.

    I think you are very ignorant and should do some research on everything you just said.

    At least the RAM is a little better than the pathetic 4GB machines have been shipping with since 2009.

    I have been playing around with computers for almost two decades and as a role of thumb a computer should support three times what can be considered a 'normal' amount of RAM to not be memory starved before the rest of the system has reach it's useful end of life.

    So in 2012 a laptop should support 12 GB of RAM even if only 4 GB is needed right now. But who knows, maybe we have made computers disposable too a much larger extent since they are so much more affordable today than ten years ago.

    "it’s quite disappointing to see the lack of emphasis on notebook display quality. Let's hope Windows 8 changes that."

    Why would windows8 change anything? It's software. The point is to get sales from people who tend to not know the difference. Same with the $1200-1500 slates with windows7... How is 8 going to change the price of the hardware... It doesn't.

    Hence win8 tables are already fail.

    Just from the Windows 8 systems that have debuted, it should be pretty clear that manufacturers are completely rethinking the way PCs are designed and built. If you haven't realized that yet, I'd suggest paying a bit more attention.
  • Belard - Wednesday, October 10, 2012 - link

    I've been paying attention.

    MS came out with the Surface, blaming their partners for making crappy tablets... in which case, please point out a tablet-oriented OS MS has ever shipped? WP7 was only for phones.

    I completely understand WHAT and WHY Microsoft is doing with Windows 8. They did it wrong. They hired untalented brain-dead middle-management to design a new OS UI called Metro, which at best - works on phones.

    I too think the Desktop as we know it, will become a very rare thing in the homes 5+ years from now. Win8 is a bad mixture of a consumer mobile UI and a classic desktop that has been cut off at knees.

    Ultrabooks are just think notebooks, nothing more. For 1/3 the price you gain about 1.5lbs and about 3/4 of an inch. They have been selling badly since Intel has started pushing it. Typical PC notebook sales are in the $350~500 range. A low end gamer notebook can be had for about $750~900. If you really want something thin and light, a tablet with a keyboard will do.

    WART tablets are really no different than WP7/8 are "Windows". They are going to sell for $400~600 to go against Android and iPads... *yawn*. bait and switch there, when the buyer realizes he doesn't have a "windows" device at all and would need to spend $1000~1400 for a good Slate.
    (In case you missed it, Ultrabook sales are tanking) So with ZERO compatibility with actual Windows Software, why bother? Then why bother with a $1200 Win8 tablet when you can get an iPad with a better screen for $500?

    Lets see those Win7 tablet sales... not exactly flying off the shelf there, are they?

    The same people who didn't buy WP7 phones, won't be buying WP8 models either. MS is in a battle 3rd place with RIM... and that is sad.

    The bad consumer experience many/most people will have with Win8's METRO will NOT generate sales of WP8/WART devices.

    The success of WP8/WART *IS* based on the reception of Windows 8. (Which I have running all by itself on a notebook)

    How do I feel about Windows8? I finally replaced my Q6600 desktop with a new i5-3570K build with SSD, 16GB of RAM, etc this week. Installed with a $140 Win7Pro, as I have ZERO plans of spending a dime on Win8. I have 4 various WinXP Retail discs from PC's retired long ago. So getting the $40 Win8 is a none issue. I would like to have gone for the deal, but Win8 isn't worth $1 to put onto my hardware.

    So again... Windows8 *WILL NOT* change the sales of Ultrabooks.

    Well, let's put it this way. Windows 8 is Microsoft's first REAL entrance into the consumer touchscreen market, so now, we're talking touchscreens aplenty on not just laptops. Secondly, you get tablets with extremely good screens and resolutions and you're not having to spend the earth on them anymore. Finally, Microsoft Surface is coming in two flavours, and chances are it's going to rip Intel's Ultrabook strategy out from under its own feet. Why wouldn't you at least attempt to make a viable product?
  • Belard - Wednesday, October 10, 2012 - link

    Ultrabooks are bombing... What Win8 tablet sells will only eat into Ultrabook sales.

    Remember the Netbook craze from 3~4 years ago? Cute little portable notebooks that were $250~300. The iPad murdered the market.

    I was in FRYs yesterday... the Ultrabook section has lighted displays... $$$ being spent by Intel. I was the only one there, I walked by - I think I touched one. *meh*. Most of the customers and sales staff were in the $350~500 notebook isle and I saw two people at the gaming notebook area.

    Ultrabook is sad.
