[comp.sys.ibm.pc] Reverse Num-Lock problems

bobc@killer.Dallas.TX.US (Bob Calbridge) (04/19/89)

Here's a problem that has started to pop up lately at our school district.
Under certain circumstances the numeric key pad acts contrary to what the 
numlock light says.  We suspect anything from the keyboard to the software.
So far this has happened using two different software packages that do totally
different things.
Personally, I don't know why these people don't shift their interpretation of
the numlock light.  However, I would like to be able to provide some explanation
for this phenomenom.  Does anyone have anything to offer?

Thanks,
Bob

      My guess would be that you are running some software that
      talks directly to the 8041 ( or 8042 ) keyboard controller,
      and that software may have 'mistakenly?' switched on/off the
      numlock light.  If you look in the tech ref for your machine
      you will find that its a fairly easy task to turn  on/off the
      keyboard lights, and that their state relative to the actual
      state of the keyboard is one of convention not requirement.
      This is the most probable explanation of your problem...
      Hope it helps..
