powerbook 2400c tip of the week
during startup, just after the "welcome to mac" screen… the powerbook will attempt to initialize the pc card cage, and eject any inserted cards.
if this fails for whatever reason, the computer will instantly shut down.

after much messing about I mostly succeeded in performing a polarizer replacement on this 2400c panel

\

the soap method @jmacz mentioned was indispensable... highly advise removing the backlight first though...not perfect, but sure beats a crackled smelly vinegar panel

check your PowerBook Duo trackballz... earlier revs seem have a radial lytic cap that leaks

disassembled a 2400c trackpad. yuck! crumbly foam! and some mystery stickyness. i suppose this explains why some 2400c have floppy trackbuttons
