SITUATION
Just had a situation where the TOUCHPAD on an HP G65 laptop wasn't working. Here's the short answer.
SHORT ANSWER
- uninstall the drivers
- restart
- install drivers that came with laptop: c:\swsetup\drivers\touchpad
- restart
- click CONTROL PANEL > MOUSE. You should be able to enable the touchpad (LuxPad) in there somewhere.
LONG ANSWER
Initially, I updated the drivers to the newest on the hp.com/support website. That didn't work. Then I tried to use the drivers directly from SYNAPTIC website. That didn't work.
The light in the upper-left wasn't working at all, so I thought it was a hardware issue. I finally tried the drivers that came with the laptop. Bingo. It's just bad drivers.
You'd think by 2011 these things would get easier. Shees.
FINAL SOLUTION
Buy a DELL LATITUDE if you're going Windows. Click here to see how: http://screenr.com/xVG
PS -I am no way affiliated with DELL, it's just a recommendation from experience. You don't have these types of issues. Spending 1 hour on a trackpad is ridiculous.
