    To be honest I'm not sure! How do I tell or what does it look like? Thanks alot :o)

  • bbmnearly26 Nov 19, 2008

    Yes mate all are connected correctly. There was no power going through the old board so I'm assuming because it has power now the board is working! Would I be wrong? How do I test the board if I am wrong? Thanks alot :o)

  • bbmnearly26 Nov 19, 2008

    Its a laptop mate sorry I should have said that. I know where they are in a PC but not a laptop! Is it the little thing I had to place in another compartment next to the ram compartment on the back? It slotted into place and 2 little screws hold it in place if that helps. Thanks again :o)

  • bbmnearly26 Nov 19, 2008

    The power supply works for sure as it was tested on another laptop. Thanks

  • bbmnearly26 Nov 19, 2008

    I left my laptop in to get fixed and 2 different places and both told me it was the motherborad but they wouldnt do it. So I replaced it myself. I put everything back where it was meant to go but now when I switch it on the screen blinks once and then stays black. I had no power before I change the board but now I do. Apart from that I know nothing! Thanks

  • bbmnearly26 Nov 19, 2008

    No didn't work but thanks for trying ;o)

  • bbmnearly26 Nov 19, 2008

    Unfortunatly still no luck but Thanks for trying :o)

  • bbmnearly26 Nov 19, 2008

    well everything lights up, I don't know if they work. I just connected a monitor but it didnt work. If it was an inverter problem shouldn't I hear windows starting? I don't hear anything. All that happens is the lights light up but they didnt do that before I replaced the main board. Thanks for your help :o)

    there could be a problem with the PSU ( power supply unit ) and this may have been the original problem, so you could have wasted your money on a new motherboard.
    check the power supply to make sure it works

    ok, the next thing for you to do is check all connections to the display, also check the inverter (underneath the monitor display) and check that they are snug and plugged in properly, after that check that the memory to make sure its inserted properly and not defective

    this could possibly be an inverter problem ( display ) does everything work appart from display? connect an external monitor to check this !!!

Did you connect the screen cables on the right way? Inverter cable?
Did you test the new motherboard before replace it?

I HAVE A ACER ASPIRE 5100 & WHEN I TURN IT ON THE SCREEN IS BLACK & WONT DO ANYTHING. THEN ABOUT ONCE EVERY SO OFTEN IT DOES BOOT UP BUT TELLS ME THAT I HAVE TO REINSTALL WINDOWS & WHEN I GOT...


You might have a bad AC adapter, bad Battery or bad motherboard.
1.) AC Adapter about $60
2.) Battery around $100.00
3.) Motherboard around ?

I would start with adapter first. If you see that you have to go to Number 2 or 3. You might to just get a whole Laptop, if this one is not still under warrenty.

To list all of the specifications for your Aspire here would take too much space.
You can download the manual directly from Acer for your 5100 series notebook. The manual will provide you all of its specifications. (Click on the link to open Acer's web site);

Once the site opends click, Driver Download located at the left side.
Under, Select Product Family click Notebook. (Not Netbook)
In the next window click, Aspire.
In the third window scroll down & click on, Aspire 5100.
Click the Document button. Lastly, click on the white arror to download the manual. File named: AS5110_5100_3100-ENG-OLM_0616.zip

Acer Aspire 5101 Laptop, powering but nothing else


If it won't go past the login screen, you should try restoring it from CD first, and then replacing the hard drive if that doesn't work. I don't have all the details, but from what you describe I don't agree with the motherboard diagnosis.
