Keyboard/Input problem(s) on W500

[westsailor]

Not long ago my 'end' key stopped working. It was pretty sudden because it use it a lot to dim the screen. About the same time my left arrow key became intermittent.

Then, the right button on my (wireless) mouse stopped working and also seemed to generate 'random' left button signals (i.e. it would suddenly select text, or select shortcuts on its own). lately I've begun to notice I sometimes cannot switch to a window/close/minimize FireFox (3.6.23). In order to 'regain control' I either have to switch tasks via task manager or 'show desktop'. then it works fine again.

I first thought the mouse was dying on me but it seems to work fine on my T60.

Makes me think I'm having some kind of 'input' problem on the W500.

Any ideas?
