Hi,

I just made an experience on my T61 (8897-CTO). I put the laptop to
sleep this morning and then resumed it this evening. I took the battery
status before and after, and here is the result:

corsac@hidalgo: date -R
Thu, 13 Nov 2008 08:19:06 +0100
corsac@hidalgo: acpitool -B
  Battery #1     : present
    Remaining capacity : 52430 mWh, 99.77%
    Design capacity    : 56160 mWh
    Last full capacity : 52550 mWh, 93.57% of design capacity
    Capacity loss      : 6.428%
    Present rate       : 0 mW
    Charging state     : charged
    Battery type       : rechargeable, LION
    Model number       : COMPATIBLE
    Serial number      :    38

[asleep for a day]
corsac@hidalgo: date -R
Thu, 13 Nov 2008 21:35:46 +0100
corsac@hidalgo: acpitool -B
  Battery #1     : present
    Remaining capacity : 42890 mWh, 81.62%, 02:28:25
    Design capacity    : 56160 mWh
    Last full capacity : 52550 mWh, 93.57% of design capacity
    Capacity loss      : 6.428%
    Present rate       : 17339 mW
    Charging state     : discharging
    Battery type       : rechargeable, LION
    Model number       : COMPATIBLE
    Serial number      :    38

So 52430 =E2=86=92 42890, that means 10W just while asleep. I find that way=
 to
much, but I'm not sure how this could be fixed.

BIOS is 2.21 (latest version afaik), kernel is 2.6.28-rc4.

If anybody has some info on this, it'd be appreciated.

Cheers,
