Hello,My laptop has decided to turn off and on until it runs the power down. It did it last week I left it unplugged and an hour later it had decided to stay on. I carried on using it all last week when yesterday it did it again. Only this time it didnt right its self. Help.

Maybe its overheating. Can you open the cpu bay and check for dust blocking the vents or fan?

I dont think so I have a feeling it was one of the updates ?
I have tried it again but it just lights up clicks then turns off.

Have you tried running Windows repair from the Windows install cd?
If it is a bad update, the repair process should fix it.
