Touchpad or keyboard not working

Hello,

Sometimes it differs but you can try pressing FN and F7 together on your keyboard to see if that will enable the touchpad again.FN should be next to your left-ctrl on your laptop keyboard.

On other Acers, there's either a seperate button to enable the touchpad or a different Function key. See on your keyboard the function keys and choose the one that looks like a tochpad, with a pointing hand. Sometimes the icon on the key just looks like a mini-touch-pad.

If the touchpad has gone bad there's not much you can do, unless it just happens to have a loose connection. You can try disassembling the keyboard to get access to the touchpad cable and verify it but to be honest, that's an unlikely scenario.
Can you plugin a usb mouse? Or you could try an external touchpad like the Bamboo made by Wacom although that's a bit expensive. Again, it would need a usb connection though.

Bad motherboard or a failed attempt at a bios upgrade/flash

the keyboard is defective. I would suggest ordering one off ebay and getting a computer shop to install one

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

Aspire D250.....

Hold down function key fn (lower left on keyboard) and tap F7 key once..

please replaced the laptop ,other option u r put the button & clean the button

have you tried updating the driver
or go to control panel and mouse and check the settings in there
does your laptop work with a normal mouse

attach a usb keyboard to the laptop, then check

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
