Acer Keyboard Mouse Problem

By jzurb ·
I am using a Acer 5672 with Synaptics drivers and XP pro sp1 for both the keyboard and mouse. I don't know what happened recently but now my keyboard and mouse are not working. I have not installed any new software before this happened. I am able to use a usb mouse with no problems. And the keyboard and mouse on the laptop work in the bios and in safe mode. I have done a chkdisk and a thorough virus and spyware scan with no results. I have reinstalled the latest synaptics drivers but no change. Under device manager there is no mouse driver listed for the laptop only the external usb mouse driver is there. It used to be listed under mice as a touchpad. I have performed a system restore to an earlier date and it still is not working. It appears Windows is not even seeing the touchpad anymore. Any suggestions Thanks

A client of mine has a different brand of notebook, but similar problem. He was sent a bootable CD that re-installs the touchpad, from the manufacturer. Problem occurs occassionally and the CD fixes it.

Do This !! ..

by lafernando In reply to Same problem i am facing

I had the exact same problem and after much confusion i found out what the problem is, it's the BATTERY .. i guess somethings wrong with it and the ACPI functionalities in the computer .. after removing the battery, everything works fine ..

NHC use

by chrishonson In reply to Do This !! ..

I had the same exact problem and pulling the battery out fixed it. I'm wondering how you knew this. Did you ever use NHC or mess with ACPI on your own. I upgraded to a newer version of NHC at right about the same time that i had the problem so it's likely the culprit. Now the question is: how do i fix it so the battery works.

Hello ..

by lafernando In reply to NHC use

Yeah I installed NHC sometime back .. no idea if that's the problem or not .. but i can't remember changing any settings with that or anything. I guessed it's something to do with ACPI cos one time when i booted with a linux live cd, it had the option to turn off ACPI functionalities, after that the computer worked fine. that's how i guessed somethings wrong in that area ..

Fixed Problem

Thanks for the tip. This piece of advice saved my sister $1500 to buy a new laptop. The "expert" at her local computer shop told her to buy a new laptop. I spent five minutes googling the problem and now the problem is fixed. Thanks for the help.

by ramirez_818 In reply to Fixed Problem

i have an acer aspire 3650. the touchpad and keyboard do not work. i suspected overheating when i took off the bottom panel and the heat sink fan had been covered in dust. i removed the dust, put back the laptop, same problem. no touchpad or keyboard. so i booted it up without the battery. still same problem. cant boot of any OS disc since i cant change boot sequence or press a key to boot off disc..... any solutions ?

I thought it would be important for people to know that this has worked on several different systems. This worked for me on the first try. Thanks for posting the solution. I'm sure it will help others too.

Hi guys,

I just wanted to confirm as well that it worked for me. I'm also wondering if any of you guys bought a new battery for the computer and if you had the same problem with the new battery.
