ps2 dead

By ogie_2001 ·
I have an old Tekram P6b40-A4X motherboard that the ps2 connectors on seem to have died. All of a sudden i get "no keyboard attached" error on bootup even though i've tested it with 2 known good keyboards after the problem showed up.

I just wantto know if anyone has had this problem before and is it an indication that the entire board is about to die or is it possible it will work for quite some time.

Thanks in advance to anyone who answers

I have seen this happen several times, half the time it is just the keyboard or mouse plug not being fully seated and a bit loose in the socket. About half the time it was the BIOS setting for using PS2 keyboard having to be set properly (never did find out how they changed).

Only time it turned out to be the PS2 sockets going faulty I solved the problem by adding USB ports and getting USB keyboard and mouse (was cheaper than a new motherboard).

PS2 ports rarely go faulty, clean, check seating, sheck BIOS, should solve the problem.

Thanks for your quick reply.
It was working but just stopped all of a sudden without any changes. The plug is seated firmly and no keyboard will work in the socket. I do have a usb keyboard that does work. I just wanted to know if I will soon be changing motherboards.

I wouldn't worry too much about the motherboard going bad. The diagnostic and corrective steps you've taken so far are right on target. My guess would be that one of the solder connections for the PS2 port broke free or something tiny is shorting the connector. If you're going to mess around more with it, you might try getting some canned air and blowing out the area where the connector joins the motherboard. Otherwise just continue using the USB keyboard and move on.

The electronics for the PS/2 port can be damaged if the mouse or keyboard are "hot-plugged".

Like all over-stress damage, the failure may not show up right away.

Since the PS/2 port has it's own controller IC, it is likely that the rest of themotherboard will continue to function properly.

So, go ahead and use your USB keyboard and mouse.
