T440 some keys are working and others are not

#1 Post by trott3r » Mon Sep 14, 2020 2:45 pm

Hello,

An odd problem in that some keys are working but others do not respond at all.
I thought it might be the ribbon cable not seated correctly.
So i took the keyboard out and reinserted but the same keys dont work.
I even started holding down the bad keys and stretched and wiggled the ribbon cable but not even a temporarily that
a key worked.

I assume this must mean something internal on the keyboard has died?
It cant possibly anything else can it?

thanks for your time
Martin

Have you tried cleaning the ribbon cable? The blue-colored tip of the ribbon cable might be heavily stained with dirt, so I would suggest cleaning it.

The contacts look great on the ribbon cable of the keybarod and the connector on the motherboard.
The blue bit is just coating and does not conduct as far as i know.

The machine while second hand is in good condition with no keyboard wear evident

Thanks
Martin
