Hi I have the above laptop and it will not work, but sometime it will get as far as the windows desktop before it shuts down. I have tried with the battery in battery out battery only mains only hard drive removed Ram removed almost every combination you can think of. Press the on button and it will switch straight back off, sometimes it will stay on and you can here the DVD drive start up and then the CPU fans come on but no screen, sometimes it will get passed the P.O.S.T stage and start to boot up but then switch off. I even managed to get into the BIOS screen and reset that to the default setting, but alas it still won’t switch on correctly. Anyone any ideas please
