As the title says my laptop (Compaq Presario r3000 WinXP Pro, Pentium 4) shuts down at the oddest times. Now usually it happens when I accidently move the charging/power cord. (I need to leave the cord in because my battery has been shot for a while.) So I think it might have something to do with the power connection but then sometimes it just shuts down when I'm not even touching it.
Could it be that the cpu is getting too hot? I've tried taking the back cover off to clean out the fans but I couldn't get one of the screws out because my screwdriver broke. So I figure I'm going to try that first when I find a new screwdriver thats not a piece of junk.
Any other suggestions?

You've stated the 2 most obvious places to start looking. Heat could cause it, or the power connection inside the laptop could be loose. Possibly where it's soldered to the board

Gently wiggle the cord - does it shut down whenever you do this? If so, it's either the power cord or the connection inside the case. Test the power cord (while wiggling it) with a multimeter to rule out the power cord.

it does shut down when I wiggle the cord. Where could I get one of those multimeters? Would the people at Best Buy be able to resolder the connection or do I need to take it to a specialist?

You can get a multimeter almost anywhere that sells tools - mine cost $10 at WalMart. But you can probably get Best Buy to check it for free with their multimeter if you ask.

BestBuy won't be able to solder the interior connection - but if you bought the computer from there they can send it out for repair. If you have one of their service plans this may be covered under it (but you'll have to check) - if not, the repair would be pretty expensive. Generally, the service center will replace the motherboard rather than solder the connection - that runs $300 to $600!!! :thumbsup:

If it's not covered under their service plans, I'd suggest a smaller, local repair shop that does work on laptops. I've seen this done once, and the total cost for parts was around $50 - so the repair should run around $100 or so.
