The power is on but the screen is black

In the first instance, try a Power Reset

The "black screen of *****" is usually very easy to repair on a laptop. First turn your computer off by pressing and holding down the start button. Next unplug the computer and then remove the battery. Press and hold down the start button for about 60 seconds. Release the button and plug in the computer. Press the start button and the display should return. Replace the battery. If this does not work, try it again up to four times. No results usually indicates a bad mother board.

If that doesn't fix it, it may be the power adapter that lights the screen.

remove the battery from bottom, plug into ac power pack, and try it that way

Have you tried plugging in an external monitor to the graphics port?
This would get you going again and would help reduce the possibilities of what is wrong.

You turned on your laptop and horrors upon horrors, the screen is BLACK! You see that the laptop has power but besides that nothing is happening.
I want you to know that there is a very good chance you can get out of this situation quickly and without any cost. This fix works on all brands of laptops:


• 1) TAKE OUT YOUR LAPTOP BATTERY
• 2) REMOVE YOUR AC ADAPTOR CORD, that's the wall power, remove it.
• 3) NOW HOLD DOWN THE POWER BUTTON FOR 30 SECONDS
That will drain any static electricity that has built up on your laptop system board and many times fixes the problem of a black screen.
After the 30 seconds re-connect your laptop to the wall power and hit the power button normally and see if the laptop comes back up.
Replace your battery.
or if wont start
Here are the fix steps:
1. Turn off your computer
2. Disconnect every wire from it (including power)
3. Disconnect the battery from the bottom of the computer.
There will be two tabs labeled 1 and 2.
4. Re-plug in the power wire. (the battery should not be in the computer)
5. Turn on the power. The screen will work. Choose start windows normally. (if you get that screen)
6. Go to Control Panel -> (Mobile PC) -> Power Options -> Under Balanced choose change plan settings
7. Choose Change advanced power settings
8. Find Processor power management and change the minimum processor state from 5% to 100% for each On battery and Plugged in.
9. Click Apply then OK
10. Shut down you computer.
11. Disconnect the power cord.
12. Re-install the battery on the bottom of the laptop, plug in the power cord, and restart the computer.

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

Dear friend you mention long beeps/few times beeps.
Its mean its RAM problem, Remove the ram from the ram slot & clean it by napkin & use a brash for cleaning ram slot. Then fix it back again. After that power on the laptop & see what's going. If the same sound again , that's mean the ram not working, its damaged. So buy/ arrange a working ram and fix it on the slot. Now power on and run the laptop for work.
Thanks & waiting for your reply.

go to power setting and see if ur pc is set to sleep....if so change it....
u will find the power setting in control panel

Hi guys!
I think your problem is one of the following:
1- AC Device or Batteries.
2- RAM.
3- Graphic Card.

So, plz check them by order.
I hope this problem is solved.

Check Acer's website for a BIOS update. I've seen a LOT of laptop's screen issues been related to the power saving settings in the BIOS. Sometimes screens going black very fast and not working properly can be caused by that.

The Power Inverter could also be the problem which you wouldn't be able to repair yourself. If you purchased it at Best Buy you can take it to them and they could get that fixed for you (at a charge if there is no warranty with that).
