          Re: lenovo thinkpad P50

          Hello Guys,

          I'd like to ask some expert to check if my dumped bios could boot up my system, I've downloaded UEFI util, and the working dumps, what you've posted so far and compared to mine. Parser part of the program did not show differences.

          If the case is that my bios would be fully functional then I would ask for a kind P50 owner to dump the flash from MEC1653 ("KBC") if it is not locked. Or dump and share it anyways for future use...

          Thank You!

                          Your model's P50 - Type 20EQ, check hardware issues.

                              You can use the bios file in #28, note that on Lenovo thickpad models there is a small switch at the bottom of the Mainboard, you need to use tape to push this switch down when the machine is operating (it will automatically press down when D cover is completely closed)

                                  Upload your Original BIOS here, write your Device Serial Number and someone will try to help you.

                                      Your Backup file looks empty, try to read it again correctly.

                                      The Compressed file size is "293.5 KB" and it should be more than that, maybe 6MB or more.

                                          Yes I know that, but it's an empty file. If it's a good file, its size should be more than that after compressing.

                                            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

                                            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 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...

                                            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

                                            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...
