If that is consistently 35 minutes then it makes me wonder how the
BIOS power saving settings are configured.  I would guess that the
BIOS is not seeing any input and therefore turning the machine off
because it thinks it is idle.  I believe that after the OS is booted
it takes over these things.  But memtest may not be programmed to do
this for that machine while the linux kernel in knoppix does.

Just a guess...

Not a bad guess. But if that's the case, it must be firm-coded into the BIOS; I could find no power-saving options in the BIOS setup screens. I had not thought about memtest86 perhaps looking idle to the system whereas sitting at a Knoppix boot prompt would not. Your idea gives me an idea for another test; tomorrow I'll see if I can load memtest86 but pause it so it doesn't check memory, and see if it still powers off at 35 mins; if so, that would seem to eliminate faulty RAM as being the cause of the power-down.
