If the adapter works on other model adapters fine.
when you try to power up does the comp beep a few times.
first off disconnect power and remove battery,reconnect battery and adapter and try to power up.
could be build up off dust (bad connection with power button)
just press it hard and try to wriggle it about .all pc 's especially laptops are dust collecters.on the the outside they may look mint but on the inside you got a mini sahara going on

Try removing the battery and try it just on AC.

What happens exactly? Does it turn on but nothing happens or is it not even powering up at all?

If it doesnt power up at all then try another AC adapter.

Screen stays black, despite computer is on antivirus program is working


Hello,

The screen might be in sleep or hibernation mode, try move the mouse, and check if it will respond. If not forcely turned OFF the laptop, remove the power sources ( charger and battery) and hold down the power button for 10 secs. Put the power sources back and turn ON the laptop.

Hope it works :)

Acer Laptop Black Screen


Just to be clear this is not a fix for screen problems, this is a fix for a problem that prevents the laptop from booting at all. The laptop would not even attempt a POST and so would not even get as far as trying to output anything to the display.

I'm no expert but just wanted to share a fix that worked for me. For me it was a problem with the laptop not coming out of hibernation properly and completely freezing, the only option was to power off. On reboot nothing would happen, the screen would not even be initialised so it is nothing to do with the screen.

I can only theorise what the problem may be. As the solution is to remove the power lead, remove the battery and hold down the power button it would seem to be an issue with the laptop retaining some residual charge which is preventing the laptop from booting. I've heard of other poeple who have managed to fix this by simply letting the battery run out and then leave it overnight, this will again dissipate any residual charge but is just a much slower way of doing it. Holding the power button down with no power sources attached will dissipate this charge and allow the laptop to boot when a power source is reattached.

Unfortunately if the laptop boots and the screen is blank then it is a different issue, if the image on the screen is faint it is most likely a problem with the backlight and in these instances this fix will not work. Before posting this I thought this was an isolated incident but there have been so many replies it would appear to be a more common issue than I thought and works on many different models, not just the DV6599 that I've tried it on

Keyboard & mouse are dead


I just fixed this problem by doing the following:

Hard power-off (hold the power button until the laptop turns off)
Unplug the AC adaptor
Remove the battery
Plug in the AC adaptor
Hold ctrl and turn the power on. You should arrive at a black screen.
Hard power-off again, then turn the power on.
