Hi all,

A friend of mine brought me her laptop (Acer ES1-512-C6SJ) which doesn't boot at all (no bip, nothing on screen).
When I press power button, screen remains black, cpu fan works only for a few seconds and power led blinks (1s on, 4-5s off) for ever.

What I've done:
- Tested power adapter ok with another laptop
- Unpluged power cable and battery, pressed power button for 30s, then plugged back power cable -> still no boot
- Tested RAM ok with another laptop
- Removed RAM -> still no boot but power led doesn't blink, it stays on in this case
- Tried flashing bios following theses instructions -> USB key blinks only for a few seconds (stop blinking when cpu fan stops)

Seems to be a dead motherboard, how can I be sure of that ?
If you have other tracks, I would really appreciate. I would like to avoid replacing motherboard by a new one (quite expansive).

Thanks for your help and sorry for my english, I'm french ;-)
Pierre
