It could be the RAM. Try taking the Ram out, clean it and the slots it fits into, (with a soft dry paintbrush) then replace it again. If you have more than one Ram stick, put one in first. Then restart your computer, if it does not work, take it out and put the other one in.

If it does work with the first one, then put the other one back in too and try to reboot again.
If it does work but only with one, then the other one is faulty.

Always make sure that you disconnect the computer from the mains before opening it.

I hope this helps

Return the laptop to the place of purchase because you still have warranty coverage, any tampering will void warranty.

When i power up my hp pavillion laptop the screen stays black and it beeps 3 times and does nothing


3 beeps is usually related to the memory.

Try re-seating / booting with just one stick of memory and see what happens.

Acer aspire one power button comes on but screen doesn't come on.


1/ Take a close look at the display in bright light; can you see anything there? (If so then the CCFL (or its power supply) needs replacing on the display
2/ hook up an external monitor and see if that works (or at least if the light stays green on the monitor)
3/ Any boot beep? any "Windows sound"?
4/ try removing the battery and (using only external power) see if it starts.
4/ remove the battery AND the external supply, hold the power switch in at least 30 seconds. Hoojk it up again, try it.
