Laptop problem: freezing mouse cursor
I received a new old Compaq 6715b laptop via TradeMe today. It has a problem which I haven’t yet solved: the mouse cursor freezes. Sometimes when the computer first starts both the trackpad and USB-connected optical mouse work fine, then after a short time either or both will respond jerkily, and then stop moving altogether. Even after the cursor has stopped moving, the trackpad buttons still work. I’ve updated the video driver (ATI Radeon Mobility x1250) and uninstalled mouse drivers from Device Manager, but to no avail. Suggestions welcome.

The trackpads have a feature called “palm check” which ensures that it doesn’t move the mouse when your palm is on it. Sometimes this can be triggered incorrectly causing the mouse to stop responding if the trackpad is warm or has too much moisture on it. You can disable the feature from the trackpad software called Synaptics (download from hp.co.nz if it’s not installed). I had this issue on my hp tablet pc (which is actually very similar to the 6715b), when the lid was closed the “palm check” was triggered after time due to warmth build up.
Thanks Aidan, I’ll try that out. One more bit of data to add: the trackpad and mouse always work fine when the laptop is running on battery power only.
