My MSI Wind touchpad started drifting towards bottom-left corner, when untouched. It's useless, the cursor runs away before I click on a selected point. I suspect hardware problem, it has been unstable since the beginning.
Reading between the lines here, I realized that it might be moisture. Is there a way to fix this without taking the whole thing apart? (Warranty is void already due to upgrade, but I would have to unscrew the mother board.) How to handle this anyway, if the disassemble is necessary? Should I use alcohol or something different?
Is there another possible cause?
I tried to use a blower brush on external case surface without success. The device looks clean: no dust, no grease.
EDIT: I looked inside and found no signs of damage. The touchpad area is actually just an imprinted in a case, so no moisture could have gotten there.
SOLVED: It turned out to be software problem. After installing a driver (
xf86-input-synaptics), the touchpad not only behaves, but also gets scroll and tap features. The problem was that the default driver seemed to work at first not raising my suspicion.
