This didnt work . just random reboots and no post
You need to write these two bios at same time if you did this then there will no bios problem
Verify problem by beep codes.
In this model you should get beep errors sound in speakers
 
Then check replacing bios chips and check motherboard
There is a bios file i got here that worked with your ec bios bin but there is a manufacture unlock mode message . can you fix it with my information , thank you .
