Something's going wrong with my laptop's power, but I can't figure out what.
Fully charged, a battery will say it's got three hours of power. Forty minutes later, the laptop will shut down. Restarted, it says it has about thirty percent power. Right now, running on AC, it says that the battery is 75 percent charged. If I unplug, it says it has about nineteen minutes of power left. I thought maybe its the battery itself?, so I switched to an alternate. Same performance.
Yuck. It feels as if a new laptop may be in my future.
