it's very tricky to fix.... because the ic is so small

I have a Dell 1150. Bought it used. Someone tried to repair the jack before - and used ACID core solder. I can tell the difference. Close inspection of the circuit traces reveal the traces eaten away at the jack connections.
They then connected the center ground of the jack to the four outer lug grounds of the DC jack, and the end positive trace jumped across with a bridged glob of solder to the surface mount component directly in front of the positive end line of the DC jack where the on board circuit line runs to.
It ran O.K. and charged the battery - but only installed Windows XP (Non-Dell) completely one time, and other times it would fail and blue screen on a 0000000A error or NTFS.sys error. (After I had upgraded the BIOS to A07) When I copied a complete working XP O/S to the drive and booted it that way, (and fixed the config and system32 errors) I got an inaccessible boot device error (missing specialty driver). O.K. I expected that and ordered a Dell XP install CD
When I upgraded the BIOS from version A03 to A07, It went fine. Then I tried to upgrade the processor from a 2.66 to a 3.06 SL7A non HT and replaced the DC jack soldering job at the same time. It wasn't until I got a good look at the traces under magnification that I felt the thing would not likely charge again - because the surface mount component directly in front of the jack looked damaged and lifted from the board.
I put IT BACK LIKE THEY HAD SOLDERED IT and sure enough it would boot, but no video with out a jumper from the on board video ground to the DC jack ground, and it will not charge now.
Is that surface mount component something you can fix? It is the one directly where the positive trace line leads to. (It looks like a surface mount resistor - even the equivalent in a regular carbon resistor would be acceptable)
