My Dell model is Inspiron 640m. The problem is my touchpad is working beyond my control. Sometimes it don't move and sometimes it hard to moves. The worst is that, it click automatically........ Please...


I would recommend either to have the laptop disassembled & replace the touchpad with a good one, or alternatively disable the touchpad in the Mouse applet in Control Panel & use an external USB mouse.

Inspiron 640m


Portable batteries are considered a consumable item because as they are used, there is some degradation to the battery. The average life of a portable battery is 300 to 500 discharge/recharge cycles. After that point, the battery's ability to hold a charge slowly decreases, to where it will only power the system for 10 to 15 minutes even when indicating a full charge.

If this is the Original System Battery, then you will need to get a replacement battery to have the system run for a longer period on battery only.

Computer does not work anymore


You could have a faulty adapter. Get it checked out and or borrow one to test your laptop to determine whether the laptop or adapter is at fault.
