My acer aspire 7520-5185 will not turn on


Take out the battery then press and hold power button for about 30 seconds, then put battery back in again and try to turn on. Might as well leave it without the battery for some time after holding the power button. If that doesn't help try removing RAM and turning it on without it.
By the way.. any beeps?

Acer Aspire 7520 doesn't start up!


There should be a F key option at start up during the bios side of boot up. Look closely and quickly at the screen when starting up. You should see on that says retstore maybe.

if not just press all of the F keys skiping the ones listed for start up options and bios option.

If you have no video at all then turn off the laptop. Reseat the memory and then turn the laptop back on with just the AC Adaptor hooked up to see if you get video if not then try reseating the memory into the other slot and try turning it on again to see if you get video. If not then your motherboard may be bad. Just curious though after you turn on the laptop, does the hard drive light keep flickering like its trying to load windows?

Mine does this but what I found was that if you hold the power button down for about 10 seconds when you are turning it on, it works.
