                      I flashed it with this dump, the password remained

                      When you try to enter the BIOS, the data is automatically restored and again requires a password. Could there be a problem with volf security?

                                      your files maybe work for 450 G9 with U85 family bios, but there are also 450 G9 with U72 family bios, so I recommend users to check which bios family version they have. Also they have to write back MAC Adress and win key.

                                      TONGFANG "GM7TG7P" Bios Password Problem?

                                      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...

                                      Hello,😇😇😇
                                      I need help unlocking the BIOS password on my HP ProBook 11 G2 laptop.

                                      🔧 Model: HP ProBook 11 G2
                                      📦 Serial Number: 8CG72478MY
                                      🆔 UUID: 6F5ED686-5532-11E7-A2E2-911C6404E011
                                      🔒 BIOS Status: Locked with password

                                      The laptop is no longer under warranty and HP refused to help me.
                                      I’m looking for a custom SMC.bin file.

                                      I don't have a CH341A programmer, so it's difficult for me to provide a BIOS file.

                                      Thanks a lot for your help!🙏🙏🙏...

                                      HP Omen 15-dh0052nf power-on & bios password

                                      Hello everyone, I come here to tell you my problem regarding the power-on password. It is not a bios reset demand, and i can't have any access to windows. This is the bios and power-on password that is blocking all other things.

                                      My Omen 15-dh0052nf purchased second-hand was configured with the bios password upon purchase (very simple password :P ).

                                      Having decided to sell it in order to get something more powerful, I reset all BIOS settings and set a blank administrator password. But the power-on password cannot be changed to a blank one so I let the actual password set....

                                      Should I buy a Lenovo Thinkpad E495 with bios password?
                                      by RMDUiFT
                                      Good day. I apologize if I posted this in the wrong topic. I saw somebody selling a Thinkpad E495 with a Ryzen 3500U CPU near me. In the pictures the laptop is running windows 10. I contacted the seller and asked a few questions about upgradability and if it has a bios password on it. He confirmed it has a bios password. I searched through the forum, I found a guide regarding removing the bios password using the autopatcher, I also found a thread with the e495 where people requested help with unlocking the bios password.

                                      I have a few questions:
                                      • If I would buy this laptop and have
