    It works also for my Acer 5742z.Thanks !

  3. I just replaced my hard drive on my acer aspire 4743. How do I get the computer to recognize the disk that Acer sent me? Or maybe I should ask what do I do next. The computer turns on but I get this black screen with scrolling data going fast and then it stops and asks “Do you want to set up VLANs now y:n?” At the top of the screen is says “Welcome to pfSense 2.1.5-RELEASE …”
    Some other things it says: “No core dumps found.” “Creating symlinks……done.” “External config loader 1.0 is now starting…” Launching the init system… done.” “Initializing…………………done.” “Starting device manager (devd)…done.” “Loading configuration……done.” “Default interfaces not found — Running interface assignment option. alc0: link state changed to DOWN”
    Any help would be fantastic. Thanks

  4. Thank you.. Just now wanna open all of it just because want to change the keyboard only. Luckily bump this webside.

  5. Thank you very much. Its help me changing the CMOS battery easily. Your sharing really helps me.

    My acer was working great one day then we turned it off and tried to turn it on again and no power. The 2 lights come on but it won’t boot. We get like one click from the hard drive that’s it. I’ve pulled it all apart as you instructed looking for some obvious flaws but all looks good. There’s a bit of fluff in the fan and dirt in places but no corrosion or hot spots. Could it be one of the small coin batteries? or the power jack like you said you could put a new one in??? I know its an old computer but its been great and we love Win 7, hate the new 10, just want my computer back.
