    Greetings .
    Can someone help me fix the bios on lenovo Thinkpad P50 type 20EQ-S20D00.
    With the original bios, the laptop cannot turn on at all, and does not turn on any lights. With a bios dump from another laptop (same type), everything works normally, the only thing that is problem is a delay in turning on the screen for about 20 seconds after pressing turn on button.

                    Thanks for the effort.
                    It doesn't work with this bios. it turns on for 3 seconds and then turns off. So every time I press the power button.

                                        Hi, I have a ThinkPad P50 I bought used on eBay, with an invoice from the seller. The seller doesn't know the password, and I need to remove the BIOS password. I have the CH341 flasher purchased from Amazon along with the 8-pin clamp. Can you tell me how to extract the BIOS and then decrypt it?
                                        I also need to identify the correct chip to read.

                                                Summary of BIOS Whitelist Removal Problem


                                                Problem:
                                                I am attempting to remove the WWAN card whitelist from my Lenovo ThinkPad T560.
                                                Initial Findings:
                                                • My current BIOS version is N1KET58W (1.45).
                                                • I have a CH341A programmer and have successfully created two full backups of my BIOS.
                                                • I have the ability to use command-line tools on a Linux machine.
                                                Troubleshooting Steps & Conclusions:
                                                • I attempted to use several automated and manual patching methods on my N1KET58W (1.45) BIOS, including using hex strings. These attempts all failed.
                                                • I concluded that the

                                                Hello everyone,

                                                First, the data in brief:
                                                Manufacturer: Lenovo
                                                Model: ThinkPad L15 G3 21C3-0016GE

                                                IC Bios 2​: MX25L25673G
                                                EC Chip: NPCX997KAABX

                                                So far I've been a silent reader, but now I need your help

                                                I bought a laptop. The seller said the bios was locked. I was looking for a way to remove this ban.
                                                I then got the CH341A and pulled the corresponding files from here https://www.badcaps.net/forum/troubl...evices-and-ele...

                                                Lenovo Thinkpad X1 carbon 11th Gen BIOS problem

                                                Hi everyone.

                                                I have an engineering sample of a Lenovo ThinkPad X1 Carbon 11th Gen (TYPE 21HM-2FVT05, S/N PF-40G7CD) with an Intel Core i7 1360P (ES – Intel 0000). Since this is an engineering sample, the BIOS had a massive number of various settings. One day, I was experimenting with the BIOS settings and, after saving them, the laptop stopped booting and played a melody after pressing the power button, signaling error code 0002 (Internal bus error), just like in this post: https://www.badcaps.net/forum/troubl...shooting-lapto...

                                                Hi!
                                                Went dumpster-diving and found a bricked Lenovo P14S in trash, few weeks earlier. Symptoms - no screen, no POST, no beep, just keyboard LEDs flashing on powerup. Mute button+LED was responding though, and the display self-test was still working (via the key combo Ctrl+Fn+Power held for some seconds, see the Service manual).

                                                Incidentally, Windows 11 have recently started auto-flashing computer BIOS in our region. Even more suspiciously, Lenovo has released a BIOS update just few days before the PC was trashed. About a week later, the BIOS update image has been oficially marked...

                                                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.
