sounds like your video card is dead ... without computer Specs can't tell you what video card to get but your local computer shop can fix for you

correodemie, Your ACER AL2016 will need to have it's "switch-mode-power-supply/CCFL inverter supply" trouble shooted and repaired. DIY repair cost less than $30. Out of warranty service $35 to $75, more if circuit board replaced. Read my and other techs FIXYA profiles to discover all the options you have for your BLACK screen symptom. Follow the links to other web sites for even more useful info. DO THAT before you do anything else. 12fixlouie

morinj_04, "Switch-mode-power-supply" going into partial shutdown mode. Read more of my BLACK screen and BLACK and BLANK screen responses in my profile. You will get the hint as to what to do!!!

Seem that your screen resolution changed. Turn off the notebook and again switch it back press F8 until it shows a list of option and then select SAFE MODE. Select it and enter into safe mode.

After welcome screen Right click on Desktop and select properties.

You will get Display Properties window.

Then select the Settings TAB in Display Properties. There select the screen resolution as low as you can 640by480 or 800by 600 then select apply and restart the Laptop.

The notebool should work normally as previously it work.

Hope this will be usefull

Thanks & regards

I've got the same situation. I think it is old enought to break. I just can't turn on the light behind the screen.

two case trouble reason and need to do:
1) back light driver (inverter) works not stable and DC power protect. it near some component damage, should repair inverter by egineer.
2) back light (lamp) over life cycle so protect by the inverter, should change new lamp (regular parts)
3) DC power supply not stable or component over life( wave filter capacitor), should be replaced

most common lcd monitor break down, check all electrolytic capacitors for leakage and loose board solder specially on the ccfl inverter section.
