RE: Toshiba A665 laptop mouse freezes (Synaptic Trackpad) [resolved]
Toshiba Satellite A665 laptop Synaptic trackpad (mouse freeze) understood after about 10 years.
Many people had this problem.
I had inadvertently solved it, but I didn't know why or how until I went back to using the OEM laptop power supply PA3716U-1ACA because the other power supply developed a break in the DC cord.
I had two laptop bricks that I used and kept them at two locations. The OEM being near a leather recliner where the mouse would freeze.
When I used that power supply exclusively in the other location, the freezes occurred daily.
I then ordered two laptop bricks with a grounded plug because the one that worked had a grounded plug.
The problem is now fixed.
