My laptop is dying - the jack where the power cord plugs in is loose, so the power will randomly disconnect. And since my battery is old, it's really not strong enough to make the screen readable. This is the 2nd HP laptop in a row to pull this with me. So, I'm staying away from HP this time. I'm looking at a Toshiba, Acer or Sony. All are under $500 - necessary when you don't have a job, but I NEED a computer. Anyone have any experience with any of those brands?
