Yes it does! That's a good point! I should have thought of that after posting in this thred [webmasterworld.com] a couple of times today! I wonder the battery is getting hot because it's bad. It only lasts about 10 minutes. Maybe that's what's heating up the machine. I'll give it a shot w/o the battery in tonight. We'll see if it locks up. Maybe shopping for a replacement fan would help too.
