Why does my laptop freeze up?

Episode 1181 (1:53:38)

Jane from Redding, PA

Jane's laptop consistently freezes up when she's doing things. Can that be caused by the battery? Leo says one way to test it is to remove the battery and plug it in to the AC adapter. If that resolves the issue, then it probably is the battery. But the battery is one of those that either works or doesn't work at all. It could be the power supply that is failing.
