I've got an A70z just out of warranty and its failing to start up. I get a green light on the on/off button, the fans start and the screen displays the 'Thinkcentre - To interrupt startup press enter' message and that's it. No beeps and no response to any keys.
Any ideas? I've tried removing the hard disc (no difference) and the memory chip (lots of beeps), so I can only conclude its the motherboard. Anything else I can try?
Kindly remove the hard disk cable from the system board and check if the desktop can enter into BIOS
If the issue persist then it could be system board which has issue. You may contact the Lenovo service center to get the part replace.
