    Zbook 14 problem after bios unlock

    I had a couple of older off lease Zbook 14 and 15u g2(I think) laptops that I got from an auction that I have been sitting on until I had time to mess with them. I unsoldered the bios chip, read, and went through rc and it said I was successful after which I programmed the bios chips and resoldered them. I believe it was successful because I was able to enable the USB port for a boot option. After I select the drive on the USB port to boot from I get a black screen for about 5 minutes and then it goes to a black screen with a pattern of gold or yellow dots. At that point any key reboots the machine. I am getting the same result on all of the laptops I tried unlocking with rc. Did I do something wrong or have I just got more problems?

          [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,...

          Problem with PANASONIC CF53 laptop after changing BIOS settings
          by AquaMan Ua
          Hello. I am asking you for a hint on how to solve the problem with my touchbook Panasonic CF53-2 standart model. After setting up the BIOS, the laptop displays the wrong image until Windows loads. (More precisely, it displays, but distorted, instead of the Panasonic image immediately after turning it on, it displays what is in photo #1 in the attached file) Then the image appears when Windows starts loading and then there are no problems with the screen until the reboot. If you enter the BIOS, just a black screen. If you connect an external screen, the image on it is the same as on the built-in...

          BIOS Unlock for HP zbook studio x360 g5
          by Andrew Bower
          Hi,

          I've been working on this for about a week. I've read the threads and ordered and attempted to use a programmer to pull the BIOS dump from the laptop with no luck. I tried using RcUnlocker, but keep getting a dll error even after reinstalling the C++ Redistributable. I also tried NeoUnlocker and another program. None would pull up the chip.

          That leaves me asking for help unlocking this BIOS. The laptop boots up to the Domain login with no issue. I can pull up the boot menu. Any attempt to open the BIOS or the BIOS upgrade menu is met with a password request....

          by traxformania
          Hello,

          I'm using TONGFANG "GM7TG7P" model laptop for over 3 years and i'm entering the same bios administrator password everyday. My laptop has Aptio BIOS (American Megatrends, AMI).

          But today it's not accepting my password. I'm %100 sure i'm entering the correct password.

          I'm trying to reset my bios without success.

          I tried :

          -I removed the BIOS battery and main battery. Waited for a long time but it didn't work. They already stated in the user manual that the password will not be reset even if the batteries...
