(I hope this is the correct place to post this question. It is getting increasing hard to know which website to post questions.)
My daughter's HP Pavilion Entertainment laptop, about 3 years old, started acting funny today. She had been using it to do some work, and then closed it. Later when she tried to open it to get back to what she was doing, it wouldn't come up. She shut it down, and when she tried to bring it back up it started acting very strangely. The lights along the keyboard would flash on and off, and that is all it does.
So, what's causing it to do this and why? And what do I do about it?
