Keyboard failure

By computab ·
I have a Windows 98 Toshiba 4100XCDT notebook, which was working fine till last week. Then gradually the system became slower, and then the keyboard failed. I fitted a new keyboard, but no change. I ran Pc-Check which reported the keyboard controller was ok. CAn anyone help?

If the program says the keyboard controller is fine then make sure you have properly installed the keyboard (also try using another PC Diag program to verify it is not the controller). Not sure about Toshiba but most notebook manu. have their keyboard connected with a cable to the board which very easily becomes undone when the unit is put back together.

its a ribbon cable which I ensured was pushed well into the socket before pushing down the retaining clips. this ensures that it cant get detached. I dont have another PC diag program. Can you recommend one?

Just a reminder, the socket for the ribbon cable holds pretty good but it doesn't take much for the cable to come out. As mentioned often when the unit is being put back together the cable puls free.

Also make sure you've got it connected correctly. They can go in backwards with the contacts facing the wrong way.

this only fits one way, unless you put the keyboard upside down.

I know this is gonna seem out of left field but have you checked the power to the logic board? I ask this because I had a friend's computer do the exact same thing. It turned out that the logic board was failing. With this Keyboard failure the system did not boot and just sat there getting hot. We tried switching out the keyboard and it didn't help. Like I said it turned out that the power handler on his logic board went out and casued the whole thing to end up going bad. Just a thought.

This problem righted itself after a few days. But it may be an intermittent problem
