S7-392 blank screen on boot

playdefense · February 2017

I have an older S7-392 - I had this problem for about a year, but haven't had a chance to deal with it as I've been busy at work and have a Macbook that I use there.

I'm trying to bring it back to life, but whenever I start it up, it just remains blank. Blue power light comes on, but no Acer logo, nothing. Tried connecting to an HDMI monitor, but to no avail.

There were posts elsewhere about updating BIOS. Mine originally came with 2.07. I see 2.12 as the latest, but there's no way for me to flash it as I don't get any screen. Trying to use Fn-Esc, or Fn-F2 with the extracted .exe (.fn files, etc.) didn't seem to do anything.

Any ideas of what's going on here? I haven't opened it up yet, but one of the possibilities from other posts is a blown capacitor maybe?

Any thoughts are appreciated.

Thanks for these links, but these are the same three I tried already to no avail. It doesn't matter if I plug in directly or not. I'm not even getting to the Acer logo on start-up. And, any amount of holding the power button doesn't seem to have any effect. I've tried tightening the screws with the T9 torx too. No luck...

Even fully re-charged it last night, until the battery light was blue. The other blue light for the system power seems to be coming on normally.

The only other things this could be is BIOS, which I can't seem to access. Or a hardware issue, which would be sad since we only used this laptop sporadically and took pretty good care of it.
