                                          Hello everyone,

                                          First, the data in brief:
                                          Manufacturer: Lenovo
                                          Model: ThinkPad L15 G3 21C3-0016GE
                                          motherboard: LG4 LT5 ADL RT UMA MB 8L - 448.0PZ26.0011
                                          IC Bios 1: MX77L25650F
                                          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...
                                          The laptop was brought in with a BIOS problem and a password. After reading the dump, the information was damaged. I ask for help in the BIOS with a clean ME region. Motherboard 213035-1. Serial number: PW+04e998, Type number: 21c3-0016ge

                                          Lenovo Thinkpad X1 Carbon 11th Gen BIOS issue

                                          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...

                                          Should I buy a Lenovo Thinkpad E495 with bios password?

                                          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

                                          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...
