Is there some'secret' way to easily remove screw cap covers

On IBM's Thinkpad T22 there are mounting screws that are covered by
black color-matching plastic 'covers' These covers provide a
csometically flush surface over the top of the screws. The covers
appear to 'glued' in place with double sided tape?

The cap covers along the bottom were oval shaped and came off by
gently pushing in the middle, distorting its shape. Once distorted it
was easy to then lift it out of the hole by inserting into the gap the
side of a single edge razor blade. The covers covering the hinge
screws again came out easily due to their oval shape.

However, now I'm faced with bezel screws which have round covers.
These covers I'll be looking at every time I use this thing in the
future, so don't want to destroy the covers.

Thus, the question, is there some secret to getting these cap covers
out without destroying them?

It will probably uglify the screw caps though.

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.

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.

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.

Check for volts input to the inverter board.
I had one laptop that had a blown fuse.
Fuse was near the graphics chip and looked like a cap.
Chased my tail on that one for a while.

Hook the ground clip of your scope probe to the tip to
form a loop.  Waive it around in the vicinity of the inverter.
You'll be able to tell if it's running.

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.

The irritating factor in the excess parts is that the bracket was left
on the 14mm screw that holds down the keyboard bezel, and appeared to
fit in that area EXCEPT that with the bracket in place where it fits
comfortably, the screw does NOT reach ?! I think it is an EMC
grounding bracket and probably won't have much to do with the
operation [I hope}

Post a link to a picture, please.
Is it the little bracket shown on the top of page 85?http://download.lenovo.com/ibmdl/pub/pc/pccbbs/mobiles_pdf/62p9631.pdf
