Continuously the letter 'z' is pressing and beep sound is coming during restart acer aspire one laptop. pls do the needfull

1. Check if the 'Z' key has got stuck within so that its getting pressed continuously. 2. If so, life it up using any appropriate tool and try restarting your machine. 3. connect any external keyboard and try if the same problem continues. 3. If still problem continues then the probability of having a hardware defect is more and I would suggest you to have a service professional to fix it.
I hope this is helpful to you Thanks

Does Saitek M80X wireless notebook mouse need special drivers for Acer Aspire 5742 running Win 7 64 bit?

No, the mouse is plug and play.

You have to manually pair the mouse with the dongle.

Follow this steps and retry them a few times and it will work:

  • Plug the dongle in.
  • Press the button on the dongle for two seconds so that the green light flashes on and off.
  • Press the button on the underside of the mouse once (short press).
  • Wait for the mouse to pair.
  • If it doesn't pair, press the button underneath the mouse once to continue scanning.
The whole process shouldn't take longer than 10 seconds

Hope it helps...

How do u d0 a facrory restore on an acer 9500


Start the computer, once the ACER logo appears, simultaneously press ALT + F10 to start the restore utility and follow the on-screen instructions.

If you don't have a recovery partition then you will need to use the recovery disks that you may have got when you first got the laptop.

My laptop to do inhales 5520 leaves a blue screen to me with a message stop 0x0000005x. Sometimes Windows raises but in the short while it goes out and when attempt to catch it returns to me again to leave...

the error code "HAL initialisation failed" shows that something is going really bad with your Windows installation.

Try starting the computer, while tapping the F8 button, once ever second, until you meet the windows startup menu. Select "Safe mode with networking" and see if it starts.

>two ways to go from there:

>Get a backup and reinstall Windows according to manufacturer's manual

>Try to use "System restore" and go back to a date before the occurence of the problem.

hope that helps.

Suddenly,nearly half of the keys type other characters !!!

You have a numeric keypad built into the keyboard, press the function button (FN) followed by the number lock button (num lock). Hope this helps.
