'Looks like you have to insert the tip of an

It will probably uglify the screw caps though.
Luckily, the caps are sold as part of P/N 26P9654

Thank you for that URL!
The step by steps are easy to follow.
However, for some reason after getting to the inverter PCB, replacing
with 'new' one from eBay, the LapTop still does not light up the
screen.
Whups. *Sounds like the backlight itself is worn out
or is turned off.
I take it you can bounce light off the screen to see that
an image is presented on the display, yes?
*From page 28:
"Screen blank mode
Screen blank mode has three variants, as follows:
If you press Fn+F3, or the time set on the “LCD off
timer” in IBM BIOS Setup Utility expires,
v The LCD backlight turns off.
v The hard-disk drive motor stops.
v The speaker is muted."
Also see p. 54 for LCD troubleshooting tips.
Worrisome is the fact that I have a bracket, screw, and a broken off
boss left over after re-assembly.
But that's only mechanical stuff.

pg 54 doesn't say much, just reseat connectors, hmmm
I did finally verify the image is appearing ON the LCD, all I need now
is the backlight and I'll have a working Laptop again, plus free parts-
bracket, boss, and screw.
