On power-up, desktop appeared, but no response to

you should see a small pop up when you run your mouse around the rim of the desktop then you click start webcam

I suggest you try a manual reset. Please remove battery and AC Adapter and hold down power button for 30 sec. and then put battery back in and AC adapter and try starting.

The problem is with your RAM. Dust it and re install it. It may work. If you cant get it fixed get your friends RAM and see if it is working. Check if you get any beep sound from the PC. If so the problem is with RAM and need to be changed. Thanks!

Try buyin a USB Mouse.
It will work n if yew want to solve the problem go out Acer Showroom or Serive center.

when u power up the computer u heared any beep check then num lock if u abkle to num lock on and off your cpu is ok.then tv to cpu connection we have to check.
also press F8 key when u power the cpu then go to enable vga mode.
then change resolution to 800*600 or 1024 *768

Go to control panel. Select Add hardware. Select that you connected the hardware. Find the device you need to update and tell Windows that your drivers are located on the desktop using the browse option.

I have had the same problem than djlimit.
I have contacted ACER service on line (in France, were I live) . They propose a quotation for repair against 60 Euros.
I shipped the product through (prepaid) express parcel service. I got it back 10 days later. They simply exchanged the main PCB.

I THINK YOU NEED TO UPGRADE MEMORY AND RELOAD YOUR SYSTEM FROM YOUR RECOVERY DISC THAT CAME WITH YOUR COMPUTER.

IF TIS DOESENT WORK REPLACE YOUR HARDDRIVE

Does it appear to be doing anything. Is there a flashing "_" at the top left of your screen. If not try hooking a monitor up externally and turning the laptop on.

U have a problem with hdd

 

Check RAM
