If the above suggestion does not work, try this:
- unplug every cable / peripheral from the laptop, including battery and power supply.
- push the "on" button for 5 secs (optional)
- plug everything back, replace battery and power cable.
-restart the laptop.
In my experience, this should bring back your keyboard, it's weird that some of our 2650 here at work do the same thing. Maybe static electricity build-up, I don't know.
Anyways, I hope this helps,
You are my HERO for the week! I almost bought a new keyboard! Your suggestion was the only thing that worked. The keyboard works great.
Stop by and I'll wash your car.
