Laptop powers on and all power lights come on accordingly. Fan powers on OK. But no BIOS or anything else comes on screen and HDD does not power up, HDD light does not come on either. I have taken out HDD, tested it and reseated it, it appears to be working fine. I have re seated the RAM. I have taken the battery out and discharged the power holding down the power button for 60 seconds. Nothing has worked. Any ideas?
