Bug Description
Recharge times under Oneiric for my thinkpad w520 is _painfully_ slow. Estimates for recharging from around 50% is pegged at 12.5 to 13hrs. Under Natty, I was seeing recharge times around 1 to 2 hours for a 50% charge.

Thank you for taking the time to file a bug report on this issue.
However, given the number of bugs that the Kernel Team receives during any development cycle it is impossible for us to review them all. Therefore, we occasionally resort to using automated bots to request further testing. This is such a request.
We have noted that there is a newer version of the development kernel currently in the release pocket than the one you tested when this issue was found. Please test again with the newer kernel and indicate in the bug if this issue still exists or not.
If the bug still exists, change the bug status from Incomplete to Confirmed. If the bug no longer exists, change the bug status from Incomplete to Fix Released.
Thank you for your help.
