OS?
10.4.11, and currently with a reformat and then clean install of system
that came with it, 10.4; no difference.
InputManagers?
None that I can see.
which periodically stops responding to keyboard and trackpad input.
External keyboard and mouse can be plugged into the USB ports when
this happens, and the PB will respond to them.
Do the built-ins subsequently respond after the externals are used?
As mentioned below, no, not without a restart.
Are any errors being thrown into the system log?
"IOUSBfamily is having trouble enumerating a device"
There are no visibly loose connections, and it runs fine for varying
periods of time between these episodes, but once it stops recognizing
the built in kb and trackpad it does not recognize them again without
a restart.
What is likely to cause this behavior?
Might be worth disconnecting the built-ins and reseating their cables.
Tried that already, with no change. I also find it suspicious that they
both always quit working simultaneously.
I'm thinking maybe somehow the logic board is failing, but AHT detects
no problems.
thanks,
