I fixed my computer. The laptop screen had been going dark. When I replaced the screen, I lost the little rubber covers of the screws that hold it in place. They'd been coming a little loose... so I just tightened them up with a little Phillips screwdriver and it all went back to normal.
My Dad used to spend Saturday evenings cursing under the bonnet of his many secondhand cars (all rubbish of course). For me computer hardware fulfils the same role. I (heart) my little Toshiba.
