Asus Eee 900 – Battery Drain while Power off

 eee battery

Several eee 900 users experimented this problem when they left their fully charged Eeepcs with the battery plugged in and the power turned off.

After a day resting it went down to 50% and after a couple of days it was all consumed.

It might be a feature of the bios because when you have your laptop turned off you can charge your gadgets and ipods using the usb ports.

The webcam is also a big sink where battery life leaks through so i turned it off in the bios quite easily as i wasnt using it regularly.

I then went and disabled the memory card slot and i experimented a big difference in my power.

So:

  • Don’t panic if your eeepc discharges if you leave him resting with the battery plugged.
    Disable those features that you won’t be using in a daily basis (you can turn them on again when you feel the urge).
    Keep your battery unplugged and in a cold place, if you are not going to use it in a long time keep it charged at 40% level.
    Try installing the 802 bios, they might have solved this issue (not tested yet though).
    Get yourself a more capacity battery at eBay.

    Hello, I have the battery drain problem (as many others). It drains by about 10% every day, while powered off. Disabling the camera does not help at all. I haven’t tried disabling usb and card reader, but I don’t think it makes much sense having to enable them everytime you want to use them (Which is most of the time).

    The EeePC 900 is just faulty. Yes, I do panic, this shouldn’t be happening. ASUS should acknowledge the problem and solve it.

    Bought in good faith for its battery life of up to 3 hours – nothing like it. I have other laptops for work so I know how to treat them correctly battery wise.

    I haven’t disabled the SD as I presume just taking the card out should solve the exit of power????

    hi… i had the same drain problem with my toshiba nb200… it used to drain about 10% when it’s off about 12 hours… i’ve just tried to turn off wake on lan and usb sleep & charge (both on the software and bios)… and it works… thanks for your blog… i never had this problem anymore…
