    Bios corruption? ThinkPad x240s 5-beeps*2 no boot

    Help needed, the attached bios dump, from a ThinkPad x240s, gives 5 short beeps twice at startup and no boot. Is it bios corruption? From what I read here in other threads it appears so. Can someone be so kind to have a look to see if it needs fixing, with a clean ME as well if necessary?
    Many thanks!

    Problem solved: a compressed section where all DXE drivers are stored in the bios region was corrupt (see images below)
    A replacement region, excluding the SEC core, from another x240s dump fixed the problem.

          Asus ROG Ally X -RC72LA - changed hidden bios settings with 'Smokeless-UMAF', won't get past boot logo
          by throwaway327
          ASUS ROG Ally X - (Handheld Gaming PC)
          Model No: RC72LA
          Serial No: SBNVKD001014459

          Hi all, I've spent the past week digging through the forums and guides to try correct my foolish mistake of changing hidden settings while tinkering around, and to be honest my heads overloaded so I'm hoping you'll be able to help.

          I used a tool called 'Smokeless-UMAF' to access usually hidden settings in the bios. I tweaked one or two 'safe' things but made the mistake of tweaking a lot of settings under 'USB/Thunderbolt Configurations' when I didn't know what they did. For...

          Lenovo ThinkPad L15 G3 Bios 1 IC conductor track
          by 1g0r
          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

          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:

          Hi, I have a few of these & they came with a custom bios boot logo, no passwords etc.

          2 x were brand new unused but with custom boot logo, 1 I installed Windows/ran updates then it bricked itself. 1 wouldn't get past the custom bios boot logo.

          The third I loaded windows, took a backup of the bios chip, then tried to flash several different clean bios's via programmer which all caused it to not boot. I tried to reflash the original bios both using clip & desoldering but...

          Thinkpad X1 Yoga Gen 3 ,How to know if the BIOS is corrupted
          by Loki_Fido
          Hi everyone, hope everyone's having a great day.

          I have a Lenovo Thinkpad X1 Yoga Gen 3 for repair. (20LES3T900)
          I looked in every corner and the laptop seems fine. Its pulling 500mA but no display, no noise, nothing.

          So I assume its a BIOS issue. I downloaded the BIOS with CH341A and opened it on ME Analyser and didn't receive any errors.
          Does this mean the BIOS is fine? making it a hardware issue?

          I downloaded fresh BIIOS from the Lenovo site and used Hex Editor replace the Lenovo's BIOS into my BIOS region. But the file size ended up being...
