Can't turn off mouse pad, i use a wireless, aspire 5720

do you have disassembly it????? try to reconnect cables in right position .

put your mouse over the item then press down and hold left key then use your finger on the pad and just slide your finger across the pad,then when you get to were you want the item togo then just lift your finger off and let go of the left key.

This can be accomplished a couple of ways. Depending on the model of your computer there may be a pressure sensitive switch under the mouse pad that pressing a little harder will actuate. Another method is there might be 'virtual' mouse buttons on your trackpad. Put one finger in the flower left corner and drag on the pad with another. Finally, there is a setting for a double click drag and drop. Tap the mouse pad twice and on the second tap keep your finger on the pad and move it. Good luck!

goto control panel and accesibility then mouse'
Do the settings.
Hope it works

On touchpads if you touch the pad twice in quick succession it acts as a click and the cursor will move to the mouse pointer location. In mouse settings disable "tapping"

Try going to Control Panel > Mouse and "enable" Touch Pad Actuation

Try the F9 key(hold the FN key and tap F9)

Fn+F7 is the key combo to enable (and disable) the touch pad. Try it and see if it wakes the mouse up again.

check driver in device manager update
in control panel check the settings for mouse.
clean the mouse pad
let me know
