I still wouldn't rule out PowerManager problems before I suspected the hard
drive
This is a clip from Sydney Ho, who is one of several savants who've written
on this common problem. I strongly recommend everyone clip this as it's
come in handy for me many times.

disassembly

>Now, because I've troubleshot my own 2400s, back to back, I want to relate

After
