My touchpad is spinning lately… If I just hold my finger on it, then the mouse pointer jumps wildly from top to bottom or the zoom gets out of focus. What can you do about it?
Recalibrate?!
And how does it work?!
You can't say that flat - which brand / model is it?
Sony Vaio SVE14A3M6EB
Maybe it can be the driver - these are all installed correctly?
Here you can find eg. A calibration tool: https://www.sony-asia.com/electronics/support/downloads/Y0005992
Check also if updates are available - these are sometimes also miraculous.
Reinstall the driver / update, keep the touchpad clean.
Most touchpads are not very good and muck over time.
