My computer screen continuously turns black and the only way to get it back to normal is to press the little rubber button near the power button. After it returns to normal, it turns black within 5 seconds, so I have to keep pressing the rubber thing (sorry, I don't know what that's called). My computer is the Acer Aspire 5100. Can you please help me?

I think the little rubber button must be the one in the lower corner of the plastic face that goes around the screen? If so you have one of several problems.

1. That little rubber button is a screw cover and it conceals a small Phillips head screw that may be loose and shorting the wire that carries the signal to your screen. Gently pry out the little button and carefully tighten the screw.

2. If that doesn't solve your problem, here is the first of the further possibilities. A little panel behind that same screen border of plastic (it called the "bezel") named the "inverter" has a loose plug or is wearing out.

3. The LCD (screen) has a plug attached to the wire that runs by the screw behind the bumper which is loose inside where it plugs into the motherboard.

These problems need to be checked by someone very familiar with taking apart and repairing laptops. But at least now, you know what the problem might be and can talk to a repair guy about it and not get taken advantage of.

Best of Luck!

It should be a loose connection. Try to get it repaired from the nearest computer shop or contact acer support
