According to Power Manager (2.5) my battery is in good condition. But, when I'm running on the battery fully charged, it all goes off after a few minutes when the gauge says that the battery is about 85% charged. Then I plug it in, turn it on, and the battery gauge says that it's 8% charged and charging. This is extremely bothersome. It happened to me before and I updated the power management software and things got better. I updated again (to 2.5) and I have this problem all over again. What to do? Richard
I'm on an X61s and the battery is about 22 months old. However, I had this problem before and it improved with the new update. Furthermore, the IBM/Lenovo Power Management software claims that the battery is in good condition.
The software is not always accurate. So how many charge cycles have you gone through? You can try to boot into the bios, then leave it on using battery power only, to see how long the battery last, if it is the software problem, then the battery discharge normally. If it is the battery problem, then the odd discharge behaviour will remain.
