I have a Toshiba Satellite that has vista installed on it. It's 3 years old and the battery lately hasn't been working very well. Recently though, I've had a problem of the battery indicator saying "plugged in not charging". I've taken out the battery and reinstalled the Microsoft ACPI-Compliant battery device. What should I do?
Depending on its size, use pattern and the type of battery, 3 years is not a small age. It is possible that this battery is indeed at the end of its useful lifecycle.
This is probably not the answer you want to hear, but it's time to buy a new battery.
