Hi guys! I had a client bring this in stating "I did an update, it lost power during it and now it wont turn on" he wasn't sure if it was a bios update but I assume it is because I get no charge indicator or anything... power is measured to the board so it seems to be getting power. I pulled the bios chip and have a dump of the current state it is in. I compared it to one downloaded from Asus in a hex editor and from my understanding you are supposed to combine the two somehow but I am not 100% clear on how to do that.. I'd love for this to be a learning experience for the next time it pops up so any information is greatly appreciated.

That worked!! You are great, thank you.Originally posted by mcplslg123 View Post
Can you point me in the right direction to learn how to combine them in the future? I am going to sit down this afternoon and compare the two just to try and see the difference.
Thanks again!Comment

Re: need bios on Asus Q552U
Its simple. Extract bios region from your non working dump with UEFI tool and save it as "OLD BIOS REGN". Now download asus update file and compare size of both the files-it has to be 100% same. IF same in size, you can replace bios region with asus update in uefi tool and save the new bios and flash.
In your case, the file was not same size. You need to compare both the files in hex editor and chop off extra bytes from web update to make it same size. To make matters worse, your old bios region header is corrupt-so it will be difficult for you to understand the beginning of file(in asus update). A little bit of experience will help but atleast you can try to understand by comparing the two files.Comment
