Lenovo G70 touchpad reacting slow and on its own

From time to time the touchpad mouse can have some weird issues, recently it was reacting automatically and slow at the same time making it difficult to use at all.

It came all of the sudden: After booting my Lenovo G70 one day the above described things happened. The touchpad mouse reacted weird and unfortunately I did not have another external mouse to test.

The settings in control panel still seemed normal.

I know this laptop had some mouse issues sometimes such as that the mouse suddenly froze and needed to be reactivated again.

This time it was something else, so I rebooted and it didn't change at all. So I got to use an old trick:

• turning off
• removing the battery for a few minutes
• pressing the power button for 30 seconds
• waiting little bit
• putting back the battery
• turning on again

And then the issue was gone. Easy and efficient!

Mouse gone in Windows 10

You're using Windows 10 with your laptop and suddenly you can't see and move the mouse with your touchpad anymore. Here's a way out.

A first attempt would be to just reboot your computer, even though it's unlikely to work. Another idea is to plug in a USB mouse, unplug it and hope that the touchpad is now working.

If that also doesn`t work go to the control panel or Settings. Select 'Mouse' (or 'Mouse & Touchpad'). Go to the Mouse properties ('additional mouse options').

Select the ELAN tab (maybe called differently on another laptop, this was on a Lenovo one) and enable the device which should be disabled at that point.

I also experienced similar issues with Windows 8 and it could be solved in more or less the same way. This issue can occur from time to time.
