Long evening ahead it seems Wink

I would just cut the pins close to the chip's casing and then desolder pins by gently pulling them from the other side. This does not damage the board as much as the attempt to desolder the whole chip...

Clean resoldering here! Desoldering is often the most tricky part. Did you use a solder pump or absorbing/fiber thing (don't know the english name for that) ?

It's called "desoldering pump" and that's the great tool. But you have to keep it clean and lubricated so it sucks well. Big smile

Congratz on fixing your computer! Always nice to have more of them alive. Smile

Yes, you need to keep certain things (and sometimes - people) clean and lubricated so they could work well. Wink
