Ремонт: Ноутбуков, Компьютеров :: Acer DA0ZAWMB8G Rev G IT8987E-CXA EC firmware needed..

EC Dump is in the BIOS. search at 300000h. if necessary, cut out from the BIOS. hex editor can be cut out.
Here is an example of the beginning of the EC firmware in the BIOS.
Attachment:

ec.JPG [ 99.34 KiB | Viewed 2 times ]

p.s.
If we don’t know how, send the BIOS from the board to me in a private message (ЛС). I'll cut it out.

Here is my original bios

is everything right ?

P.S I have a bunch of BXA versions instead of CXA, do you think it should work ?

1. It’s better not to make the BIOS public here. there is a windows key. I wrote what to send in a private message. Better remove the file.

I can't edit my post, I've sent a report but still not answered..

PU3002 = TMP708AIDBVR
any analogues ??

P.S I have a bunch of BXA versions instead of CXA, do you think it should work ?

It’s better to put what was standing. after all, the revision version of BXA is lower than CXA. Here's the service firmware to try. cut out EC. bios from here.

thanks for the links.. Serguz05 писал(а): 1. It’s better not to make the BIOS public here. there is a windows key. I wrote what to send in a private message. Better remove the file. I can't edit my post, I've sent a report but still not answered.. the BXA version made the "ITE Busy" on the SVOD3, replaced with a new CXA version and filled with my dump but still no reaction to the power button.. EC_PWROK = 0v traced to SYS_SHDN# = 0.4v traced to Thermal Sensor PU3002 which was shorted, removed and +5VPCU appeared but no +3VPCU 3V_LDO became 0.6v, found a knocked-out capacitor PC6022, installed and 3V_LDO became 3.3v again and +3VPCU appeared EC_PWROK = 3v and the board started PU3002 = TMP708AIDBVR any analogues ??
