My system specs:
thinkpad r61 type- 7743- a17
nvidia quadro nvs 140m graphics chip
120 gb hdd
4 gb ddr2 ram
intel core 2 duo 1.8 ghz
my r61 motherboard's northbridge and southbridge is glued to the motherboard. the glue is a white semi-transparent hard fluid which is difficult to remove.This glue under the chip is making it hard to remove it. Could anyone please suggest me a solvent or anything which would help me take out the aforesaid parts without damaging the motherboard.
p.s. these are the faulty parts due to which i am experiencing power issues on my motherboard

Unless you have *professional* re-balling equipment, you should NOT be even thinking about touching these chips.
You most certainly WILL damage the motherboard in the process.

I'd be doubtful of the original diagnosis in the first place...
My opinion - and I've worked on thousands of ThinkPads over the past decade - that your "tech" has absolutely no clue what he/she is talking about.
