My partner is just about to throw it out the window.
He has an old Compaq laptop (it's a dinosaur) about a month ago he had to send it to the repair people at comet (it has a long warranty) as it wouldn't hold any power in the battery, they returned it with a new electrical lead and told us to buy a new battery, so we did and it worked for 10 mins before dying. After an argument with comet they came back to pick it up and replaced the harddrive, but since then the laptop keeps turning itself off every couple of minutes and re-setting.
Any ideas?
