HP Admit it's a hardware problem, Good job we have a 2 year warranty through John Lewes. But we fear the John Lewes repair centre as last time we had a device back I had to open it to see why the sound wasn't working... at the same time I thought I would renew the Thermal Paste. well new laptop boards have a clear stick over the cpu/gpu which was still in place, I would call it a lucky find: rant over!
