what kind of battery is this?<br>
If it is a Lithium-ion, it may in fact be empty and ... dead.<br>

Quote:<br>
<font face="Verdana, Arial, Helvetica, sans-serif" size="2"> Some
lithium-ion batteries fail due to excessive low discharge. If
discharged below 2.5 volts per cell, the internal safety circuit opens
and the battery appears dead. A charge with the original charger is no
longer possible. Some battery analyzers (Cadex) feature a boost
function that reactivates the protection circuit of a failed battery
and enables a recharge. However, if the cell voltage has fallen below
1.5V/cell and has remained in that state for a few days, a recharge
should be avoided because of safety concerns. To prevent failure, never
store the battery fully discharged. Apply some charge before storage,
and then charge fully before use.</font><br>

i'm having a similar issue now: the battery claims it is totally empty (0 mW 
remaining) altough it was connected to the power for the whole evening. i 
disconnected the power now, and the laptop keeps working, so the battery is 
definately not empty ...

one week ago, i updated the embedded controller program to the latest version.
i have a R51.

i'm going to try the let-it-run-down trick too (running glxgears or 
something). i hope it'll work
