Title:
  painfully slow recharge time when booted off battery

Status in “linux” package in Ubuntu:
  Incomplete
Status in “linux” source package in Oneiric:
  Invalid
Status in “linux” source package in Precise:
  Confirmed

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.
