    HP Pavilion 15 bc400ns - Complete Black Screen - Only video on live usb
    by iZakre
    Hello everybody!

    To put you in context I recently replaced the battery from my HP Pavilion 15 bc400ns with a used one, everything was going good. The same day, I decided to update the BIOS, everything went good. The thing occurred after I let the battery drain iddling on Windows 11 for the second time to calibrate it that the screen did not turn on again, the computer was on but the screen did not turn, like it would not wake from hibernation. I decided to restart the computer but got no video.

    The thing is that I had installed TeamViewer and could log into the computer...

    Lenovo laptop does not turn on, what does this number mean in a BIOS chip?
    by thxd43
    Hello, first of all, excuse me, I am using the translator, English is not my native language.

    I have a Lenovo ideapad 330S - 14IKB laptop.



    The tablet did not recognize me when I connected it, so I checked the device manager and I realized that there were many with the exclamation mark, so one by one I began to update their drivers until the sign disappeared of admiration, I even updated the BIOS, and the laptop rebooted normally and worked, so far so good, but the tablet still did not recognize me, I read on the internet that it could be due to a...

    ASUS TP500LA BIOS request/repair/merge?
    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...

    [REQUEST] Dell G3 3579 BIOS Password & AMI Protected Range/BIOS Guard Unlock
    by zenius
    Hello, I have an old Dell G3 3579 (ST: 2WQ7LP2-8FC8) with a newer 8FC8 BIOS password. I have successfully attached to the flash chip (W25Q128JVSQ) on the motherboard with a CH341A programmer and made several modifications using Intel FIT (e.g., allow software SPI write) without bricking. I was also able to boot to a modified GRUB shell where I attempted to edit many BIOS security related options like BIOS Guard/Lock, Flash Signature Override, ME FW Image Re-Flash, etc.

    Unfortunately, some of these modifications like to Intel BIOS Guard failed because it is fused into the PCH. Also,...

    Changing BIOS Serial Number After Motherboard Replacement on EliteBook x360 G3
    by Friend33
    Hello,

    I have an EliteBook x360 G3 where I had to replace the motherboard. Everything is working fine and there are no errors during boot. However, I have the issue that the serial number in the BIOS is incorrect. When I run the DMI tool under Windows, I get an error stating that I am not in Unlocked Mode and therefore cannot make any changes. I was able to change the Asset Tag directly in the BIOS. Now I am wondering, can I simply read the BIOS chip, change the serial number with a hex editor, and write it back, or what other options do I have? The old motherboard did not work at...
