I have an interesting problem that has me beat. I am running 4 older AT style systems, 200Mhz AMD K6’s, as point of sale stations. I use PS2 keyboards on them with built in touch pad, utilizing a PS2/AT adapter for keyboard connection to MB. They have been working fine for the last 4+ years. 3 days ago, one of the stations lost keyboard connection. Unplug, plug – it worked for a day. Then it lost completely and I’ve been unable to get it to connect.
I switch one of the other stations over there, it also fails to work. I switch keyboards from other system. Same thing. I pull both systems out and place in storage. I pull a different station out of my shipping department which has not had this problem(same build system) place on my cashiers stand – it does the same thing. I now have 4 stations that will not boot without this keyboard error (sounds like a key is stuck) I’ve tried brand new keyboards, swapped hard drives, brand new adapters, etc. I am baffled. I now have 4 stations down and cannot get either of them to boot past that keyboard error. I pull the keyboard, and it boots up fine except for Keyboard not found message on screen.
I bring one of the stations (most recent out of shipping dept) over to my office to work on, plug it in – it works. I test it, change harddrives, put it through the paces, change keyboards with ones from the store – no problem. It works. I take it back to the store, plug it in – doesn’t work. Swap keyboards, try new adapters, etc. Doesn’t work. Grrrrr. I bring it back to office – doesn’t work over here now. Nothing I do can get it to work.
What am I missing? Does anyone have any ideas? Why did they all quit at the same time. Am going to clear the CMOS right now to see if that helps. Don’t see why it should, but it’s my last idea.
Thanks all.
