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.

Re: need bios on Asus Q552U
Your bios is definitely bricked. try this bios(your bios merged with asus web update) -
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

With ASUS, not everything is quite so simple. I will show you my way. It may be longer or harder but it is the right way to do it in my humble opinion.
For example, you can have 3 similar ASUS motherboards, all being the same model, all of which will have different BIOS versions.
I will give you an example and my version of preparing BIOS from ASUS website and in the process I am always cleaning Intel ME while doing it so you have fully cleaned BIOS, no DMI data, no password, nothing.

Hi all, I've spent the past week digging through the forums and guides to try correct my foolish mistake of changing hidden settings while tinkering around, and to be honest my heads overloaded so I'm hoping you'll be able to help.
I used a tool called 'Smokeless-UMAF' to access usually hidden settings in the bios. I tweaked one or two 'safe' things but made the mistake of tweaking a lot of settings under 'USB/Thunderbolt Configurations' when I didn't know what they did. For... -
I had 3 people contact me in a week because Windows suddenly didn't boot:
As you can see, all 3 are ASUS computers, but I believe the common factor is the BIOS being American Megatrends (AMIBIOS/APTIO).
The first two recovered just fine after a restart, but the third one didn't and was brought to me. The model is F541UV (X541UV).
Setup allows to add a boot option manually and the operating system boots just fine from both bootx64.efi and bootmgr.efi. However, there is no way whatsoever to save the option(s): upon a reboot the machine goes straight... -

Hi, I hope some one has some advice for me. I searched the forums but didn't see anything relevant. I acquired two identical Dell 9010 Mid Tower computers from a business office upgrade (they were going to throw them out). Both of them have the same motherboard (00F82W). One of them works flawlessly. The other one had a corrupted BIOS. I tried flashing numerous main BIOS and EC files from the internet, but none of them worked. I decided to copy the main BIOS and EC from the working 9010 computer and successfully flashed the corrupted BIOS. This got the computer able to boot again and run norm...04-23-2025, 04:30 PM
