Why my computer can't power up?
Why my computer can't power up?
Hello everyone! I bought a Lenovo PC two years ago but hadn't used it since the last year. Then I found I even can't power it up a few days ago. Who can tell me the reason? Thank you!
1. Is the PC totally "dead", or when you hit the on-switch are there any signs of life whatever?
e.g.
(a) Any LED's blinking?
(b) Any fans running?
2. If it is dead:
(a) Is the mains power getting to the PSU?
Plugged in at the wall, and switched on, and connections all good?
Is there power output at the wall-plug?
(b) Is the on-switch on the PC OK?
If it isn't:
Tried shorting the pins on the mobo?
(c) PSU voltages OK?
e.g.
(a) Any LED's blinking?
(b) Any fans running?
