                        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

                        [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,...

                        Help needed in unlocking BIOS Supervisor password - Lenovo X1 Yoga 5th Gen
                        by baaligoga
                        Good day, everyone!

                        I'm encountering an issue with my Lenovo X1 Yoga 5th Gen laptop related to the BIOS supervisor password. I'm seeking assistance and guidance from the knowledgeable members of this community in resolving this problem.

                        I am no expert and cannot perform soldering or unsoldering of the chip from the board. Therefore, I attempted to use an EZP 2023 programmer with a clip to extract the BIOS bin file without removing the BIOS chip from the motherboard. The BIOS chip has the following letters imprinted on it: "Winbond 25Q80DVNIG 2026". I used the...

                        Bios password Lenovo Legion 16IRX8H
                        by darknwo
                        Hi, can someone help me please with the removal of the bios password of this dump.
                        Someone desoldered the bios chip, tried several "methods" but with no luck, and he gave me the dump to try to search some help.
                        For now he deleted more things and bios password is gone but laptop doesn't show serial, model etc.

                        Also, I updated bios to latest version, when he will write the dump again without password, it should be better to put back the old version that was orignally or doesn't matter? Because from what I've read this laptop has 3 bios chips, don't know if has...

                        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...
