    My colleague's T61p used to sip its brand new 6-cell battery at the 1%/h rate (in both hibernation and turn-off states).
    I examined all the known tips'n'tricks (see T61p battery leakage in hibernation site:forum.notebookreview.com/lenovo-ibm/ - Google search) but to no avail.

    I therefore decided to turn off (using Windows' Device manager applet) the 'usual suspects': Bluetooth, modem, FireWire, LAN and WLAN cards.
    Once the leakage stopped, I begun to successively turn them on - and revealed that the Intel 82566MM Gigabit Network Connection card was the culprit.
    Are the LAN modules integrated with the mainboard or rather removable/replaceable?

    LAN module is integrated.

    What you describe sounds like normal battery discharge.

    it could be that option for turning the computer on via LAN signal. I would try to disable that in bios first to see what happens.

    but thanks for pointing out the problem though

    ♬ ♪ It ain't no good ♪ ♬ - Nick Cave would have sung :wink:
    I do not agree! 1% per hour means, for instance, that the laptop hibernated/turned off for a weekend will only have half of its battery charge ready to work next Monday, doesn't it?!
    Besides - after a full charge and the all night long hibernation - it stays at 100% now...
    Thanks - I had tried all these 'routine tricks' (I mean: disabling Wake on LAN in both BIOS and Windows, switching all USBs not to be ON, etc. etc.) before...
