Any advice on taking apart and repairing/replacing the hinges?
The display will not stay in one position. There is no
tension/friction in the hinge so the display falls horizontal or has
to be propped up on a pillow.

Any sources for maintenance/service manuals? IBM provides service
manuals for THinkpads. Toshiba says to call a service center...I can
see doing that while products are under warranty, but this is a
PIII-500.
