Thank you! And yes, this is true.

Once, on a customer's PC, I did this, in their office.

The fault was due to a cheap old HP LaserJet printer, with a parallel
Centronics connection. If the laser printer was connected to the PC,
whether it was turned on or not, the PC would not turn on.

Even stranger, it had worked for years.

Connected to another PC, it was fine, and without the Laserjet, the PC
was fine. Since both PCs were on the same network, I just shared the
printer when it was connected to the other PC, and from the one that
originally hosted the Laserjet, I made a network connection to the
printer. Both could print, all was working, and the customer was happy
and paid my invoice no problem.

But I had the PC totally disassembled -- RAM, everything -- before
tracing this problem. If I had disconnected the printer *first* it
would have saved me about 2 hours' work. But then, it would also have
made me about £150 less on the job.
