    Having trouble with an Acer Aspire 5742. After pressing the power button the screen backlight comes on but it stays black. The Windows(7) chime sounds and when plugged into an external VGA display everything shows fine. I've checked all the ribbon connections and also just replaced the screen. Have run Malware Bytes too. Display is still not working.

    Any ideas?

    Thanks.

    Check if the laptop has a button usually on the F1 to F12 buttons. It will say LCD or show a picture of external display. Press the blue function or FN key with that button until the display show again.

    I have an Acer Aspire 5532 and am having a problem with turning it on. If you hit the power button to turn it on, it will light up and go to a black screen, no Acer logo or anything. You have to then hold the power button to turn it off, then turn it on again and it will turn on and load into Windows like normal. It has Windows 7 Home Premium, everything is stock from Acer.

    Any idea what would cause this?

    This happened to me too once or twice.. I think it may have to do with the battery memory. What I did was keep windows on without power saving anything, and let the battery completely die.. take out the battery and smack the power button a few times. put the battery back in, with the power plugged in, and let it charge completely. No problems yet..
