I had a friend bring me a Acer Aspire 1640 laptop that was having problems with the touchpad working "jerkily" and the Keyboard getting slow or not working at all. I found that if I took the battery out and just had the AC cord plugged the problems went away! We're ordering a new battery and in the mean time she can use the laptop with just the power cord (and battery removed).

in my opinion. your touchpad driver is defected by virouse /re install once time it, second your computer touch pad hardwere is damage,check it using by another keyboard and mouse. then u can get result --thanks
Just resolved same problem on Acer Aspire 5000 by removing the battery, then goto device manager and disable "Microsoft ACPI-Compliant Control Method Battery" you can then put your existing battery back into the latop with any problems with the keyboard and touchpad. Mad solution I know but it worked for me
I SOLVE THIS ISSUE 100% WORKING THE MAIN PROBLEM IS ON THE CONTACT BETWEEN THE BATTERY WIRES AND LAPTOP IF YOU MOVE THE BATTERY IT WILL WORK SO SURE THE PROBLEM WITH THE LINK BETWEEN THE BATTERY AND THE LAPTOP SOLUTION : TO MOVE THE IRON OUT OF THE LAPTOP TO THE RIGHT TILT THEM TO RIGHT SIDE A LITTLE BECAUSE THE BATTERY WIRES IS TO THE RIGHT SIDE (WATCH THEM) NOT IN THE MIDDLE AND AFTER THAT PUT A STICK ON THE BATTERY TIGHTED IN ITS PLACE SO IT WILL NOT MOVE ITS NOT FREEZING NOW THANKS
