Our laptop has been starting to mess up lately.
The battery doesn't charge when it's plugged in. We're thinking it's the ac adapter.
About a week or so ago, I was on it, and the space bar kept going like it was being pushed. I couldn't type anything. Even the password when trying to log in. So we had to push the power button.

Now, as we click on the desktop. Every single icon starts flashing at the same time and we can't do anything.

Does anybody have any idea of what it could be, and how it can be fixed?
