In the spirit of this, i propose a list of compatible laptop chips.
Here's one to get you started:
Richtek RT8206 = Intersil ISL6236
Have just performed a replacement of a RT8206M with a ISL6236IRZ in a Fujitsu Lifebook AH531 which had no power. No 3.3v or 5v standby present, no shorted mosfets, no other damage to the board. LDO 5v was present, but no output. Replaced and it fired right up.
