I have an Acer Aspire 3620 Notebook with some strange keyboard and touch pad behaviour. Touch pad and keyboard don't function at all. Also if I plug in an external USB keyboard still don't function at all. thanks Marco

You mean touch pad is not working? Try to press and hold Fn key (bottom left side on keyboard) and one of the function keys F1 - F8 on which is engraved picture of touch pad.

Ubuntu may not supports touch you must or must install our touch drivers which would had been given you with your motherboard cd when you buyed the laptop

1 . Look for Fn function key - Most laptops have this special key Fn that is next to the Ctrl key on the keyboard. It should have a blue or green color, easy to find.

2 . Look for F1 to F12 functions keys, they are on the top row of the keypad. Look for one has an icon that looks like the touch pad, which is to control the touch pad of your laptop. It maybe F8 or F9 depends on each make of your laptop. These function keys also control the brightness, sound, wireless etc.

3 . Now hold down the Fn key and the F10 key to enable the touch pad, in this example, the Toshiba laptops. You press them again to disable it

4 . If none of the above works, plug in an USB mouse, then check into the Control Panel -> touch pad or mouse configurations. Also, check Device Manager if the touch pad driver is installed and working properly.

Thanks.Have a great day.

if you plug usb keyboard onto your laptop it will probably turn the touch pad off.
If no other keyboard is attached there is usually a switch to turn off the touch pad.
also if you attach a mouse this may disable the touchpad so you dont move the mouse pointer when you are typing

Make sure the mouse pad is enabled. Check the manual or web site for your model. Generally, the mouse pad (and other functions) can be accessed by pressing the Fn key + a specific F_ key (1-12).

Sometimes this device or others can accidentally be disabled.

when you start your system , press f1 continously on your keyboard to check ur cmos settings if they are not disable

Sorry, no solution ! it is a mother board problem in IC U22 ENE( KB910QF)
Strange, freshing the IC , it restart, but it fail again at the next boot.

Try Function-F7. That should re-activate your touchpad.

hi

your touchpad may not be working due to following reasons.

1. the touchpad driver not installed or corrupted. try reinstalling the driver.
2. due to improper usage of the pad it is demaged.
3. the button which activate the tochpad is off.
4. the sensor got weak due to degradation with time.

call the customer care and they will replace it if its under warranty.

if you find the solution useful plz rate me carefully

for aspire 3050, try to remove the battery, battery can cause many strange thing.
if you still got problem after removing battery, it's look like motherboard need repair.
