Battery Life, Heat, and Noise

Despite the incessant griping about the pokey Intel Core i3-2367M beating at the heart of the Toshiba Portege Z830, there's one place where a low-powered processor can pay dividends: battery life. The Z830 may have a weaker processor than the competing ASUS Zenbook UX21, but it also has a bigger battery. Check out this running time.

Relative Battery Life - H.264

For sheer running time, the Portege Z830 lives up to the promise of ultrabooks, being an incredibly mobile notebook that lasts for a long time off the mains. When you look at the relative battery life, things get even better, with even the Optimus-enabled ASUS Eee PC and HP's E-350-based dm1z putting in weaker showings. Intel's CULV chips have historically been big winners, and suddenly the i3-2367M doesn't look so bad anymore: it's faster in every way than Atom or Zacate, and more frugal with power to boot. That said, the Z830 also benefits from having an mSATA SSD which is also going to sip power.

All that battery life wouldn't amount to much if the Z830 was noisy or hot in the process, but surprisingly it's neither of those things. The fan has a very low whine when the system is idling that isn't particularly intrusive, and while that whine does increase in volume under load, it's still nowhere near as irritating as the fan noise is on most notebooks. Better still, despite the thin, flimsy chassis, the Z830 remains fairly cool to the touch as well. During our stress testing loop, no hot spots really surfaced: this is a very cool, very quiet notebook that's definitely fine for using as an honest to goodness laptop.

    1st page, 3rd paragraph. Is Turbo Boosy the drunk abusive cousin of Turbo Boost? Cuz I rather quite like the name. Reply

    That's what I get for editing in the engine. Though I'm not sure how I hit the "y" instead of "t" given I have a split keyboard. Probably being bad and typing with one hand or something. Reply

    192:1 contrast ratio and 40% of AdobeRGB ? Even my 12 year old eizo has better display quality.

    Also I don't get their obsession with the hideous sticker spammed all over the keyboard. Why is it only Apple that gets it?

    They probably get paid some money to put stickers on there. Reply

    Apple doesn't do co-branding, ever. If you buy a Mac, it's all about Apple and you don't need to know whether it has an Intel or Motorola CPU, an ATI or NVIDIA GPU, or any other details. You also shouldn't know whether the SSD is a decent quality Samsung a much slower and lower quality Toshiba. And for all of that, you get to pay a price premium.

    At least Apple knows how to select a good quality LCD and build everything well, but again, that's part of the price premium. The interesting thing is that Intel defines a price to qualify as an ultrabook, and everyone cuts corners to get there and thus kills the screen quality. And in this instance, build quality as well.

    I am definitely sure "Turbo Boosy" exacerbates the issue!

    Not a bad ultrabook (if one can get past that cheap display), but I like the battery life on the Zenbook UX31 better. I'd can't stress enough that I'm willing to have a heavier machine if it meant more battery capacity... one criteria most ultrabooks aren't meeting. Regular laptops which have the room, or in some cases the battery capacity just fail to meet any of the criteria an ultrabook excels in.

    Notebook vendors are still swinging and missing that niche market...

    Honestly, I would prefer the dm1z at half the price. Saw it in best buy a long time ago, but it appears to have disappeared off the shelves.

    And it seems there is a dearth of netbook size devices using the E350, which seems an ideal chip for a small portable. At least in retail stores around here, what I see is Atom netbooks and E350 15.6 in laptops. Seems a mismatch for both. Why would anyone want atom over the E350 in a netbook, and if I am going to get a 15.6 in "full size" laptop, I either want Llano for the graphics and decent CPU performance, or an Intel i3 or i5 for better CPU performance.

    Go for the Thinkpad X121e instead. With TPFanControl it's nicely quiet and the only negative point is the horrible touchpad (can't really click with it). Otherwise it's almost perfect for such a small machine (can't expect a good screen at that price point).

    Since some think that 1600 is too large a resolution for 13 inch, and alot seem to agree that what most of them have now is pretty lame, why can't more of these ultrabooks have the same screen as the mackbook air, which has a 1440 x 900 resolution? Reply
