I have a UPS 650. When it runs off the battery and it is time to shutdown the PC, seconds after I receive a pop indiciating the computer will shutdown in 30 seconds, I get an error message saying unable to shutdown due to the keyboard PS2 101/102, must update driver. There is nothing on their website for this issue and when I wrote to them, they replied back, not really knowing what i was talking about. Any ideas what could be wrong? Thanks.
