      Make a crisis recovery drive and try to flash bios.If it doesn`t work you need to clear the cmos.Remove the battery and dismantle the laptop ,remove the top case.Desolder plus side of the cmos bios battery and lift the leg or put a piece of card under it, then place the top case on,but don`t clip it down.Attatch the power button ribbon cable, with no adapter or battery press and hold the power button for 1 minute. Resolder the cmos battery, connect power button cable again and also the keyboard, and try to start with adapter , tapping f2 to enter bios. If it doesn`t enter bios or start you will have to flash the bios with a hardware bios programmer .

              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...

              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...

              NEC VersaPro PC-VRT42FBFR22B BIOS problem
              by trouble55
              Hi All,

              V-VE212(U3E1)

              [Serial number]

              [BIOS chip model]
              Macronix MX77L12850F

              I am having some problems with the BIOS of my Versapro PC-VRT42FBFR22B.

              I extracted the BIOS file (versapro001.bin 16MB) from PC-VRT42FBFR22B ROM (MX77L12850F) using CH341A and NeoProgrammer V2.2.0.10, but I don't know how to remove the BIOS password, so I can't open the BIOS even if I boot with F2.

              I also downloaded the BIOS update package (933A0400.zip) for PC-VRT42FBFR22B from the official...
