Sorry Edster, no I don't know of any. You can do a google search, that might help. I did a google search for your laptop. Similiar problems were found with other models. Could be a power supply going/gone bad (no, not the charger).
Ah, not to worry, I shall see about investing in a new computer. Desktop I think this time!

Thanks to all who offered help and advice. Much appreciated.
