I haven't had much experience soldering surface-mount components. You
need a soldering iron with a fine pointed tip, not big and stubby, and
having some small-diameter solder also helps. If you've got an old junk
network card or hard drive or something kicking around, you might
practice unsoldering and resoldering components on that before attacking
the laptop. http://www.repairfaq.org/REPAIR/F_ts...tml#TSHOOT_029
has good information on soldering and desoldering.


The correct method of removing the old chip is to get a pair of fine
anti-shock diagonal cutters and cut the remaining legs off the chip at the
package. You can then carefully unsolder the cut off legs from the
motherboard, one at a time. Position the new chip with a bit of double
sided sticky tape (or suitable substitute) and then carefully solder the 8
legs.

Attempting to unsolder all the remaining legs in one go (unless you have the
correct tools) is asking to destroy the motherboard.
