The rest of the chip. Could it be sy8386arhc (rN marking)...

Hm, cant be an 51393p. The chip on the board has only 16 pins, 51393 has 20 pins. Do u have a detailed picture of that area?

Ya, i killed it accidentally by my self, shorting with probes. Thank you!

​​​

Does somebody know, which IC this is?

Here are the files of the non-working board. Just amber light when power key pressed.

You patched file work like a charm, thank you. What about this "Absolute" thing, what is it used for?...

OK, i have backups of UC5 and UC6 and will upload them tonight....

Thank you, so can i also use this for the second Board?...

Can someone please unlock the attached BIOS?

Mainboard: FDW50 LA-J381P
Service Tag: 7GQG8D3

I bought use used replacecment, which is BIOS locked. BIOS taken from UC5.

Another question, is it possible to get a clean BIOS for the same model? The old board does not boot, may the BIOS is corrupt, Service Tag: HHW4Q73

Thank you friends...

Hi Larry,

yeah, mine too. Used some UV mask and still waiting for the replacement chips (ITE and TPS). But i wonder, what caused that burning.

What are the values for the big too caps? The right one is completely missing, the left on was blown.

And is there another component? Resistor or something? Or another small cap?

It that a common fault in this laptops? Have exactly the same burned chip/area. Does i have effect on the ITE8750E and 3.3V rail? 3.3V rail was shorted, the ITE getting hot, when in injected voltage. 3.3V Up again after removing the ITE. But still have to fix the burned 1.2V area.
