Acer Aspire 7720 powered off won't power on

[Ohmboy1976]

My Acer Aspire 7720 powered off by itself and won't power on. No power at all(no lights, no fan, no noise, no nothing) I tested the power supply and it is working. I tried unplugging it, taking out battery holding power button for 30 secs. Plugging it in without the battery and turning on. Still nothing.

Hi,

Here are some other troubleshooting steps that may help.
- Start by trying a different AC adapter while the battery is still out of the laptop and see if that will work or not.
- Proceed with reseating the RAM's if trying a different AC adapter will not work, remove them all for couple of seconds then put them back in making sure everything is seated properly.
- If it will still not work, connect an external monitor and see if you'll get any display from it. If there's a display on the external monitor that could mean that the problem is the built in display.
- But if there's still no display on the external monitor that means the problem lies in the motherboard.
