Replace the power adapter completely - dont remove components as there are no user serviceable parts inside it.

1.If the power IC is burned, it isn't the only IC that's going to be defective now. Kind of like a 'domino effect'.
2.It isn't a simple fix, of just un-soldering a component from a motherboard, when dealing with a laptop motherboard. All motherboards are built in layers, (Desktop and Laptop), but laptop motherboards are even more layered.

(Scroll down to the heading -> Lamination, then read the entire article. Also check the links at the bottom)
This means the actual circuit trace may be between layers. (Circuit trace. The thin strip of copper, left behind after the Printed Circuit Board is etched)
You won't be able to un-solder it without burning the board, (Motherboard, or also called PCB), and re-soldering is twice as tough.
You need a reflow machine, high magnification, a precise soldering station, and highly developed soldering skills.
Not trying to ruin your day, or offend your computer repair skills.
Replacing the motherboard may be the only viable option. Check Ebay-> Computers and Networking>PC Components>For Laptops and Notebooks.
Also > Laptops for Parts.
You have seen that this IC is burned? I ask because the X35, and X55, had a bad problem with the On/Off switch going bad.
