Battery Life

The ThinkPad Edge offers solid battery life, with nearly eight hours of runtime in our idle battery life test and over six hours in our internet battery benchmark. Unfortunately, this doesn't hold a candle to some of the other CULV notebooks on the market. With the same size 6-cell 5600 mAh, 63 Wh battery, the Acer 1810T gets a full two hours more idle runtime and 84 minutes more in the internet battery benchmark. The same trend holds for the Gateway EC5409c and Dell Inspiron 11z - the Edge simply cannot match their power consumption, even with similar components and an equal battery size.

Relative Battery Life

Curiously, the Edge has better battery life numbers under HD video playback than the other 6-cell CULV offerings, but that could be explained by various differences in screen, hard drive, and memory, as those are the mainly stressed parts of the video benchmarks. The disparity in power consumption and battery life becomes even larger when you compare the Edge to notebooks with 8-cell batteries, like the UL30/80Vt and Alienware M11x. The UL80Vt we tested last year offered significantly better battery life than the Edge in IGP mode, and similar battery life when running on the dedicated NVIDIA G210M graphics card.

    That intel gpu is just garbage.. not asking for much, just something that can play 1080p content without stuttering and using up the CPU like crazy.

    You are so "off topic" here dude. Please concentrate on the topic.
  • wicko - Wednesday, April 7, 2010 - link

    Uhh, right, so commenting on the laptop being discussed at hand is off-topic? Right.. I suggest laying off whatever it is you're smoking.

    Maybe he means you're off topic because the G45 does in fact do video acceleration?

    My point exactly! And also, these CPUs are not garbage. I am not content with the word "garbage".
    The CPU is great in what it does. And would you play a 1080p movie on a 13' notebook? If you have a HD screen at home you could get a HTPC for cheap these days and do whatever you like with 1080p. The CULV is better than the Atom and everything else AMD has to offer in that range...

    Im loving all the notebook reviews you guys have been pumping out lately.

    If I may make a request, could you look into the Sony CW line? It offers a i5 520, Geforce 330M and 1600*900 screen and is selling very well. I think a lot would be interested in a review on it. Its just a request though, I'm loving what you guys already put on the site.

    You guys are the gold standard for laptop review for me, you cover everything, and then back it up. I love it!

    Just like to add to the notebook list the Lenovo X201. Curious to see how it stands from the T410 you guys just reviewed.

    I own x100e... it has the same keyboard and it is horrible. I also own a T400 and T60 with IPS Flexview screen -- best laptop ever, but getting old. The standard ThinkPad keyboards are miles better... This new fashion of square boxy keys introduced by the shape-obsessed and ergonomics-retarded Apple designers is a nightmare for the industry -- I am really scared the ThinkPad T line will now go the same route... it is a clear regress.

    The new keyboard is physically monotonous -- the feeling of physical articulation is completely lost. Lenovo, please fire your originality-lacking marketing and design people. They will poison your technological marvels with the dumb Apple tricks tailored for the mindless masses...

    A cry of despair...

    Hopefully Lenovo won't mess with the T-Line... I doubt it... They are one of the important hold-outs with the CTRL-Fn key switch...

    They are proud of their new keyboards, introduced in the T400s with the enhanced ESC and DEL keys.

    The things I'd like to see with ThinkPads: switch Ctrl<>Fn (so CTRL is on outside) - some purist will complain which is WHY they haven't... but having a BIOS option to switch the keys would resolve that.

    I like the new power & VOL button... easier to find the power button.
    The new keyboard standard on ALL Thinkpads, including the SL series.

    Stop using decals on keys... which is what EVERYONE does nowadays :(
    Wouldn't mind the keyboards having LED lighting (like Apple) so the keys stand out in low-light environments. That would remove the need for the think light :) I'd pay an extra $50 for that option.

    Get rid of the stupid USB "expansion" bay which is supposed to replace a true docking bay, it sucks.

    Move the EDGE over to IdeaPad or cancel it out.... they have the S-series (netbooks), general notebooks and gaming/multimedia noteboos ($950 for 15" ATI 5730... not bad)... so keep only the AMD Edge version as a very portable notebook between net-book and the mid-range.

    Also be cool is Lenovo was clear that which notebooks didn't have ANY horrible GLOSSY screens.

    OH... we have some X200s, which are Core2 with 13" screens.

    It doesn't have any of the good Thinkpad features, except for the track point which I don't use. Why the **** is it called Thinkpad? And why didn't Lenovo at least try to stand out of the CULV croud and offer something they already have: the excellent keyboard and matte screens. That could be enough to tip the balance in favor of the Edge.
    Now give it an e-IPS panel and you've got a really nice machine.
