Obviously, YMMV, but in my 2100 one of the three solder lugs had
actually broke. The price for the part on eBay was dirt cheap, quick
to arrive, and worth the comfort of a solid repair.

In my case the laptop wouldn't even run, and once the repair was
effected, the unit booted up under battery power (must have been a
short?). Whew!

Good luck with those screws...let us know if you still need help
finding them...I needed it.
