I have no plan at all. I shut down my Acer aspire 5 earlier and after 10 minutes it started to ventilate extremely loudly. At first I thought he was doing an update or something but when I press any buttons there's no reaction. The monitor is black. Would be pretty important because I have a conference in half an hour…
Hm if you don't get a picture it may be because of your graphics card. You should go to the conference with your cell phone and maybe examine your laptop
Have you ever tried turning off the laptop? As a last solution, I try to hold the power button down for about 10 seconds in such cases. Then the laptop turns off. Then wait about 10 seconds and switch it on again. Does it work?
