    Lenovo ThinkPad L13 20R3 EC / BIOS

    Hi,
    got this device turning off after a second after switching on, no shorts, after CMOS Reset it sometimes lasts for 10 seconds but turns off then. Voltages general 20V and 3.3 on EC constantly present. I assume there's a problem with the EC FW.

    Dumped the EC, it's almost blank (Attached).

    Could anyone upload a working dump of BIOS and EC?

    Mainboard:
    LAR-1 MB
    18834-1M
    448 0HK04.001M

    Thanks!

            Serial number's not correct, but let's try with this bios ( i can't find EC file ).

            If still same problem, clear ME your bios file and reflash.

                          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
                          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 problem
                          by MaxonDomkrat
                          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...

                          Fixed: Lenovo P14s Gen 1 (type 20Y1, 20Y2) Laptop (ThinkPad) bricked by a withdrawn BIOS update (r1buj82w)
                          by akwky
                          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...

                          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
