Thanks very much! I appear to have not got the emails before this one, so I
will try and answer here.
Also, in the meantime, I run tests from the BIOS but all passed (except for the
battery which has now been removed).

Generally the only thing that could be screeching is the fan or maybe a
DVD drive. Can you listen to localize more specifically where the sound
is coming from?
There is no DVD. It is possible that it is the fan, and that is my suspicion
but I can not tell. It does happen only when there is some sort of activity in
the disk. This is not the usual mild rattling sound that happens almost all the
time, but screeching at times.
Seems like it would have to be moving parts like that.
Agreed, but the BIOS passed it FWIW. The fan also appears to blow air all
right, with a lot of gusto, but that is usual.
Or maybe there is a screech virus playing screech noises from the
speakers :-).
Possible, but it is not in the speakers. And sound plays fine.
You can't determine where on the laptop the sound is coming from?
With spinning hard disks and failing (or just poor) electronics
somewhere, I have had disk access noise feeding through the sound
output. That's much less likely with an SSD because of the very low
power usage and lack of head movement actuators.
