I have recently purchased a secondhand compaq presario 1246 from e-bay. When I use it, it frequently switches itself off. Once it has switched itself off it wont switch back on. It sometimes wont switch back on for days. I think it may have a problem with overheating, but dont understand why it doesn't switch back on once it has cooled down. I got 2 batteries with it and have tried both. I have also tried it with the power supply connected and unconnected and it still does it.
Any help would be very much appriciated. I have some university course work i need to get off and finish for next week and am starting to get a little worried.
The idiot who sold it me on e-bay wont reply to my e-mails and has now been removed as a member so no chance of a refund
