Attempted to install a serial mouse this morning and computer asked for driver (computer off and plugged in device). Tried to configure but it said driver in program not compatible. Proceeded, but weren't able to get the mouse to work with proper functionality (didn't have a mouse driver either).
Was able to turn computer off successfully. Removed mouse.
Attempted to turn computer on later in the day and was not able to get to Windows. While initializing a warning came on the screen saying there was internal stack overflow ("NAVAP" - I guess this is related to the Symmantec application in the system) and to change settings in config.sys.
Now can't seem to do anything. Screen is frozen, no DOS prompt, nothing. Have the original documentation and emergency boot disk but there is no help here. How do I turn the computer off. I want to take it to a technician for review tomorow. Do I have to let the battery run itself out for it to die? Any help appreciated. Thanks.
