Power on, black screen, no hard drive signal

[chekwech]

Hi,
My Acer Aspire One mini laptop gives me a black screen after powering on. Power light on, battery light on, NO hard drive light on and never shows anything but black. I have tried a lot of the strategies I've read here (remove battery, replace, unplug, etc., pressing various function buttons, holding power button down), still nothing. This happened once about 2 weeks ago and then it came back on after being off for a couple hours but that has not worked this time.
I do not know how to take out/replace ram (is that for Random Access Memory? I can't find anything on it that I could unplug), and I am too afraid to remove the hard drive but will do it if necessary.
Any advice???
Thanks

Hello,

Have you tried connecting your laptop to a monitor to see if it is the laptop display?

Hi there. have a good look to see if the back light of the monitor isnt going out. I have worked on a few models that have had the back light issue. After turning the unit on it displays for a short period then blanks out but if you look closely you can see the screen is working just without the backlighting.
