Touchpad And Keyboard Suddenly Stop Working

A couple weeks ago while using my laptop, the keyboard and mouse pad suddenly froze up/lost power. No response to usb ports or cd drive. The screen stayed on, fan, power, even wifi connection stayed on, but couldn't get anything moving. The power button didn't respond so I had to unplug power and remove battery to shut it down. Worked fine after I restarted it.

Now, the same thing just happened again, on a DIFFERENT laptop with a different OS, browser, everything.

WTH?

Thanks
