5/10/98: Me
Last midnight, losing of some key input response occurred frequently, and I judged that keyboard was damaged. I planed to take the machine to NCR quick-garage (one of the most famous repair service provider in Japan) next morning, let it go to sleep.
When I checked the machine with Key Caps, \-key (ideintical with back-slash key) had been held down, and Control-key and right side shift-key did not respond. Further more, the machine did not start up when it was powered by the battery, and if the AC adapter was pulled out after starting up, the brightness of sleep indicator light went very weak. The keyboard and logic board were exchanged at an NCR quick-garage, and it went back normal.
