    I need the bios for Lenovo Yoga S940-14IWL

    I need the correct bios for the Lenovo Yoga S940-14IWL. Bios to be used via eprom programmer (Xgecu TL866II plus or CH341a) . I extracted the .cap from the new bios, but I don't have a backup of the old bios. All in all, I couldn't solve it. THX in advance

            if someone wants to help me, here is the new bios.cap, and the bios backup (but I'm almost sure it's a wrong backup)

                My problem is this too. I did a forced backup with xgecu ii plus, even if it gave me an error. And then xgecu ii plus doesn't support MX25L12872 , so i selected MX25L12873 . Then i flashed the same with something wrong . In short, I made a disaster. and I don't have a healthy backup

                            Need Clean BIOS/EC Bin File for Lenovo ThinkPad Yoga 11e - Stuck with 0275 Error CMS

                            Hello everyone,

                            I am attempting a repair on a Lenovo ThinkPad Yoga 11e that is currently stuck at boot with the error: "0275 error CMS" even after setup new bios battery and will not allow me to enter the BIOS/Setup.

                            This is a critical issue that I believe requires flashing the BIOS chip directly using a programmer (e.g., CH341A/RT809H), as standard software updates or resets are not possible.

                            I have opened the laptop and identified the main BIOS chip...

                            BIOS Request - Lenovo Yoga L13 Gen3 (AMD)
                            by maeson
                            Hi dear Badcaps-Community,

                            Somehow an auto update, which I triggered before I left my laptop unattended, bricked my BIOS.
                            I was able to extract the 2MB BIOS and 16MB BIOS which I will attend. (CH341B black with NeoProgrammer 2.2.0.10)

                            The Device is a Lenovo Yoga L13 Gen3 and I was able to identify the following specifications:

                            Lenovo Yoga L13 Gen 3 AMD:

                            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

                            Lenovo Yoga X1 Gen4 - Faulty Bios or what is going on?
                            by AYsys
                            Hello dear forum members,

                            I own two Lenovo Yoga X1 Gen 4 laptops. One of them had a touchscreen problem, and I tried to fix it by externally flashing the BIOS. Unfortunately, I didn’t save the original BIOS and accidentally flashed it with a faulty one. After that, the device stopped working completely.

                            I then had the idea to make a BIOS backup from the other Yoga X1 Gen 4 (same hardware) and flash it onto the non-working device.
                            Nothing was flashed here — the BIOS was only backed up.

                            I created the backup using a CH341A Black programmer and NeoProgrammer....

                            Lenovo Thinkbook 15 G2 ITL i5 (serial number: MP2BFZEF) bios request
                            by Wahaz
                            Hello,

                            I have a Lenovo Thinkbook 15 G2 ITL i5 Laptop (serial number: MP2BFZEF) that when I turn it on, the led on the power button lights up for 5 seconds, then goes out. There's no display and nothing happens.
                            So I thought it was a Bios problem.
                            I found 3 bios chips on the board, which I read with a bios programmer: two XMC model bios chips and a Winbond model bios chip. Each XMC model bios chip has two partitions named XM25QH128A [3.3V] and XT25F128A [3.3V]. And the Winbond model bios chip has three partitions named W25Q80BL 3.3V, W25Q80xV 3.3V and W25Q80DV 3.3V....
