Nobody knows ? I may be in the wrong place ? how to move this post to "Troubleshooting Laptops, Portable, and Mobile Devices" instead of " Abit - Asus - Aopen" ?

Re: Asus EeePC 1005HA blown component

It is PQ50 on the board view ref 1.3
and it seem to be a the same for 1.1 motherboard

Ref is PMBS3906 PNP transistor

Hi everybody.
my motherboard is dead , i look at the repair guide , and conclude the +3VA_EC was short to ground, remove all caps , and disconnected sub circuit did not solve the problem. The only thing that worked for removing the short was to remove U3001
(Embedded Controller , ITE IT8985E.)

I have no data sheet for IT8985E so
My question is : If i buy a new IT8985E on aliexpress or eBay or whatever , Do I need to program / flash this chip ? Or does it execute its firmware from the external EEPROM U2801 (Winbond W25Q64FWSSIG 64MB) ?

Thank...
