IMPORTANT!
I have this issue with my Acer Laptop... It suddenly goes blank. I tried checking what could be the cause but found nothing. Part of what i've done is check the display which is working fine, I've tried pressing the power button to drain the power option, and RAM change which it doesn't work.
One important, yet confusing thing I noticed is that the computer works "at its will". I can remove the two RAM and put one back and it starts and also displays and works properly, but then fails to display when I shutdown or restart. I've tried this with both RAM and RAM slots and its same. Even when I fix the two RAMs, it will boot normally, but then fails to display at next booting and will require lots of exchange of RAM before it suddenly displays again even with RAMs that seems not to work before.
The cycle continues like that.... PLEASE, WHAT COULD BE WRONG?
