                  do not use the clip because you may have errors, remove the bios chip from the motherboard before reading or writing, if you do not have an adapter, solder the chip to the programmer, if you have nothing to remove it, solder wires between the chip and programmer..

                      the bios is corrupt and longer... remove your bios chip from the motherboard before reading or writing.. check with the HxD program that it is correct and post again..

                        Re: lenovo Flex 5 bios need

                        Hello mate thanks for looking so quickly, The chip is out
                        I read the chip 3 times, in beyond compare all 3 files are the same.

                        I have the t56 programmer with the 200mi adaptor.

                        When reading this chip do I have the , Flash & OPT Secu R & Status Reg
                        all ticked in the 3 boxes? and save as Default or save as Flash or save as OPT?
                        if this matters?

                        I will give this chip another clean up and try again.

                        Thanks.

                          Hello mate, I have cleaned up the pins and cleaned up the chip
                          it all looks really good, its the same again, maybe this bios is corrupted.
                          I have had a look at the file in the first post and its not much different.

                          Can you have one last look please mate. much appreciated.

                          Thank you.

                            Is it OPT or OTP ,if its OTP (one time programmable) don`t use that. Choose the chip that isn`t OTP

                              Thanks for explaining OPT & OTP SMDFlea I have never messed with this
                              and have always left it on the default settings, Now I know not to use it.

                              I have been looking for my old CH341A Programmer to see if I get the same
                              reading but can I find it, No.

                              Thanks for all your help.

                                          my laptop is lenovo flex 5 14ITL05

                                          recently my power supply for this laptop developed a fault.
                                          which caused a short in my usb c port -- verified with a new charger.

                                          rant: so, i went to the repair tech in my country, he asked for a huge repair cost when i decided to get it done someplace else this "great person" nicked my bios chip, asked me to be aware for repair scams lol.
                                          I was stupid and unable to find the flaw at the moment. Another repair tech told me that my bios chip was stolen and an 8mb bios chip is in place of that. he told me that a 32...

                                          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,

                                          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....

                                          Lenovo Legion Y540 – Need help repairing BIOS after bad downgrade
                                          by gestalt.exe
                                          Hi everyone,

                                          My Lenovo Legion Y540 (i7-9750H, RTX 2060) bricked after I downgraded from BHCN44WW to BHCN21WW.
                                          Laptop stopped booting entirely.

                                          I used a CH341A programmer to dump the corrupted 16MB BIOS.
                                          i then attempted the following:
                                          1. Downloaded stock BIOS BHCN39WW from Lenovo
                                          2. Trimmed it to 16MB
                                          3. Extracted the BIOS region from the corrupted dump
                                          4. Extracted the BIOS region from the stock 39WW
                                          5. Replaced the corrupted BIOS region with the stock one (within hxd , opened the corrupted dump and replaced its region by the stock)
                                          6. Injected back my LDGB / DMI
                                          ...

                                          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...
