    Problem with my ASUS X51R bios

    Hello to everyone. I have a problem with my ASUS X51R laptop. A few months ago, the system did not open because the CMOS battery is low (?) and asked for the CMOS password. I couldn't find the password and I had to replace the bios battery (took me a few hours). It worked well for the past 2 months.

    Now it says the same thing: CMOS battery low and asks for the password. I finally found the password for the laptop, but after I enter it, it goes straight to the BIOS setup where I have no idea what to do. I thought that after I enter the bios password it will enter Windows, but it enters the BIOS setup.

    Do you have any idea what should I do in the bios setup to make the windows run? Or do I have to change the bios battery again (once every 2 months...)? Thanks a lot!

    Place a new RTC battery, enter the BIOS, load BIOS defaults and Exit Saving Settings. If the problem persists the there are faulty components on the motherboard.

      The other option is to flash the BIOS. If anything goes wrong though, you will need a programmer and skills to take the BIOS chip out, program it and solder it back.

        [TUTORIAL] fix asus bios with bios from asus web support (by razor_amd)

        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.

        This is the picture of 3 similar ASUS motherboards, all of them being X555LD...

        ASUS Zenbook Pro Duo UX8402ZA BIOS
        by pirati
        Hello everyone,

        I recently bought a non-working Asus Zenbook Pro Duo OLED UX8402ZA that was listed for parts only. The seller mentioned that it had no display output but that the charging lights worked.

        When the laptop arrived (without a charger and SSD), I connected a charger and confirmed with a multimeter that it was charging the battery. However, when I tried to power it on, only the backlight of the secondary display came on. There was no image, and it didn’t boot into the BIOS.

        I decided to try flashing a new BIOS, but since I didn’t want to desolder...

        [Problem/ Request] Bricked TongFang GK7MRFR BIOS
        by cr4zychriss
        Hello everyone,
        I am requesting urgent assistance to unbrick my laptop, a rebranded TongFang GK7MRFR chassis. The laptop is completely dead following a faulty in-OS EC flash attempt.
        I have successfully used a CH341A programmer and can read/write/verify both flash chips, but using my backups/extractions has failed to restore power. The root cause is likely a corrupted Intel Management Engine (ME) region or an incompatible EC/BIOS pairing. System & Hardware Details

        by jbonavita
        Hi, my laptop wont boot at all
        With original bios no POST, only LED lights
        With alternative BIOS from model TP500LN (flashed via programmer) the notebook works again
        Some issues
        A- with bios from 500LN, it won't update from bios of model 500LA (from 500LN v203 to 500LA v300)
        B- If updated from 500LN version 203 to 300, the battery stops being recognized

        Things I tried

        1- Update / clear ME: Took the non working bios, made a backup, and did this: https://www.badcaps.net/forum/troubl...theory/trouble...
