View Full Version : [ubuntu] Battery charge drops seriously around 70% (ThinkPad)

My Lenovo ThinkPad T500 is only about a year old. Consistently, when the battery gets to about 70%, the charge drops suddenly to around 10%. This happened when I was running 10.04 under Wubi, and is still happening now that Ubuntu has its own partition. It has never happened in Windows. Screenshot included.

EDIT: It also seems to happen faster now that Ubuntu has its own partition. Under Wubi, it might go 50 min to an hour before plummeting. For comparison, Windows always got me at least 3 hours.

Time to get a new battery. If your laptop is less than a year old, your battery might still be under warranty, and you could get a new one for free.
