PCH should be $12-15 maybe a bit more last I've seen for sale, nothing near $100 or even $50 Buy one on ebay from China, ask seller to ensure no FPF burned in before shipment

* edit @Dan_422 - Hey Dan! I found your thread again after PM, now I know what we're talking about. Give me the PCH info and I'll see if I can find you one on ebay cheap.
Did you replace yourself, or someone did for you? If someone did for you, that may be why price is so high, 20% for the chip 80% for their time/work etc.

Try what plutomaniac suggested above, you might get lucky and it's fixed!

i paid that much because here in Brazil one guy only had it in hands to deliver imediatly, i had sold that notebook when it got in trouble, now i lost the sell, but no problem, since i solve the issue all will be fine... i did the replace by miself, i have bga machines etc... i will check for a new pch from china

I understand. Yes, best bet now is to buy cheap, ask for please no burned PCH Fuses, and wait for long China delivery.

I bought another chipset from china, did the procedure to clean ME of bios file, now that is working. But i don't know if the old chip came with burned fpf or it burned in first run due to the bios being in original settings (for first chip i didn't clean that before trying to boot),so for new chip i have started the mobo with me cleanned bios to avoid that possibility, wdyt ?

The old chip came with FPF already burned in, this is done manually with ME FW tools at a command prompt, not the BIOS or anything already set in BIOS or ME FW.
Nice you finally have good working system now!
