My sister gave me this laptop, but not before dropping it a number of
times. After going through dell tech support, they said that the
motherboard of the laptop was damaged, and so, i would have to shell
in 400-500 bucks to fix it. Yeah right! I disassembled the thing
according to
Dell's
Service manual. but i could determine the problem. Until, i
stumbled across
this website, it describes the exact symptoms of my 600m (it's
at the top of the page, i have ALL five problems listed there). The
site says the problem is with DC Power jack on the mainboard, and
that it can be replaced without installing a new motherboard.

Sweet! I've found
this
website, which sells the part for $50 bucks. Also,
eBay,
has 'em for even cheaper. Since i'm about 90% sure the problem is with
the DC Power Jack, i need help installing it. I've found
a
site that tells you how to do it, but, although it mentions my model
(600m) i'm not sure if the instructions apply to me. Anyway, i'm
wondering if there is a way to actually repair the DC Power jack
itself, or at least, find out what is wrong with it; or would i just
be wasting my time.

Thanks a lot.
