Recently I got the problem with this motherboard when I try to fix ec error. with updating the bios via windows. The ec error seems from ec chip or ec memory, because the keyboard disable seconds after windows start or wake up from sleep, except the display on-off key(Fn+F9).
Windows event viewer also give error message something like "ec firmware give information even windows not request it".

Hoping the problem solved by updating the bios, I got the failure when bios updating. At step bios updating ec firmware, my laptop won't to restart for hours.
Desperately I cut the process, and I got my laptop cannot started anymore, even light at start button dont come up.

So I conclude, NEVER UPDATE THE BIOS IF THERE ARE SIGNS OF HARDWARE FAILURES.

Now I want to replace my ec chip or ec memory (if this is the culprit) and reflash my bios and ec.
A. Is it the right move?
B. Is it right bios memory is 25q64fw and ec memory is Pm25lq512
C. Is flash with stock bios will not work ? What or how the right step to do?
