What you need to ask yourself is Why did the IC burn out. You may risk replacing the ic and some other fault with the motherboard burns out the new IC.

Work on daynow it don't

The modern motherboard performs many functions and connects to a wide variety of devices, but the hardware's most basic role is to connect the system's microprocessor to the rest of the computer. The central processing unit, otherwise known as the CPU, is typically housed in a socket on the motherboard. From there, the motherboard receives electrical power from the system's power supply and distributes it to the CPU.

What if the power ic of philips freevents x60 was burned?is it repairable? the value of the power ic cannot be recognized. is there a way to find what value it is?how?

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.

Regarding BIOS

BIOS stands for Basic Input/Output System.

It's a 64MegaByte (MB) program, that is 'burned' into the BIOS chip, on the motherboard.
(Chip is slang for IC.
Integrated Circuit. I suggest you go to, and in their search bar, type -> Integrated Circuit. Also look up -> BIOS)

When you push the Power On button, the Soft Power On, part of your power supply, is momentarily connected to Ground. This makes the power supply come on.

Power is supplied to the motherboard, through the 20/24-pin ATX motherboard power cable. (Also, some processors require a separate power cable, connected to the motherboard. Either a 4-pin ATX power cable, or an 8-pin EPS +12 volt power cable)

The BIOS program, on the BIOS chip, on your motherboard, receives power.
BIOS then looks to see what devices are connected to the computer, (Peripheral, and what's in the Expansion slot/s), does a Ram Memory count, then turns the processor on, and hands the computer over to the Operating System. (Windows XP is an example of an Operating System. O/S)

For more info, I suggest you check out Wikipedia. Start with Motherboard. Anything you see in Blue, is a link you click on, for more info about it.

Also check out "Computer Channel"
