    this strange acer 5100/3000 series common issue - occurring few days after the warranty went out - has the only fix by replacing mo-bo or (even better) trying elsewhere for the next laptop to buy. I did the 2nd, of course, Sony Vaio here now.
    btw, just to be clearer: no other ext usb keyboard nor mouse "fixed-the-prob" so far and mobo isn't forced anyway to see usb devices.
    that's why I guess it could be a usb ports issue, since my acer stopped to work after I've plugged in an usb device (ipod).
    it could be interesting if some skilled mate of us would try to hard "deactivate" usb and look out for what happens then...

Dear fix-the-prob Unfortunately there is no magic key to enable you to do this. Computers do not have 20 backup systems like airplanes. Which would be nice but it would cost like one too! You have two options though to solve this,

  1. Firstly either change the laptop’s keyboard (which is a bad solution if the keyboard is fine and the problem is actually the motherboard)
  2. Second is to find any USB keyboard (easy these days) plug it in an USB port at the side of the laptop. The bios is forced to see this keyboard instead of the laptop’s.
Regards Please don’t forget to rate this solution if it was helpful, it keeps us going!

In the case of my Acer, this touchpad and keyboard problem was related to ACPI and the battery. In order to get into Windows with your mouse and keyboard fully functional, remove the battery and keep your laptop plugged into the wall. When you get in, everything should be fine (you don't need safe mode for this). Once you're in, go to your Control Panel, go to System. In that pop-up, go to the hardware tab and click Device Manager. In the Device Manager, click the plus sign next to Battery. In there, right click "ACPI-Compliant Battery" or something like that and choose Disable.

Reboot with your battery in place. It should work just fine. Replacing the battery with one from eBay solved the problem on mine. Without ACPI your computer cannot go into standby and doesn't have all those nice power-management features associated with it.

Hope that helps. Your issue might not be ACPI-related. :\

Another suggestion would be to re-plug the cable that connects the keyboard to the motherboard

hope this helps

Had a problem with when I booted the Aspire 5050 laptop. The keyboard and mouse would not work after windows xp loaded. I obtained the solotion from the following link and took the below steps ->

1) Followed the acer website link and downloaded the appropriate keypad drivers by looking for Aspire 5050 (5050 is the model)

2) Put it on a pin drive.

2.5) Unplugged the acer 5050 battery and still allowed the power cord to be plugged in (in effort to save time)

3) booted the acer 5050 laptop and kept hitting F8 to go into safe mode

4) logged into safe mode as 'Admin' and ran the setup from the drivers after inserting the pin drive.

5) shutdown windows

6) plugged the battery back in, turned the power on, everything works fine.

Thanks, Rusty!

Try starting in safe mode. If it does boot in safe mode then go to HELP, THEN SYSTEM RESTORE, pick a date before you had these problems. Good luck. You start in safe mode by pressing F8 then selecting SAFE MODE from the menu.

Cant hear sound off my laptop


There are two possible reasons why your laptop is experiencing from this kind of problem.

1. Hardware problem - you need a technician to fix it.
2. Software issue - you can do it yourself

Here's how to isolate the reason why you are having this issue.

Boot to safe mode.

Restart your computer and tap F8 until you see the options to boot to safe mode. Use the arrow keys to highlight safe mode with networking. Hit enter

Once you are in safe mode, check if the sound works. If yes, then update the sound driver. You can find the sound driver in the website of the computer's manufacturer. Or you can use RadarSync to search the driver and update it without you doing anything at all. I will also scan the other drivers which are outdated.

You can also go back to the normal mode by restarting your computer and go to the device manager. Uninstall the sound driver from there and restart your computer.

I hope this helps!

If you have any questions, please drop me a line.

Vistas explorer restarting

try booting into safe mode by turning on the laptop and keep on pressing F8. It should bring you into a menu. Choose safe mode. If you can get into safe mode then click on the windows icon in the bottom right hand corner and then in the search box, type in MSCONFIG. Click on msconfig when it pulls it up and when you go into that program then choose the startup tab and disable all.

This will stop all of your programs from starting up when you go into windows. Reboot the computer from this point and see what happens after you get back into windows. If this solves the problem then that means a program starting up is the problem.
