                    Thinkpad T470 locked bios

                    Hello everyone,

                    I bought a used T470 that did not specifically mention the bios was locked, it only listed *199. My fault for not understanding what I was buying. I need help with removing the svp on the bios dump.

                    Thanks..

                        Re: Thinkpad T470 locked bios

                        Thanks aldopc but I am having issues with the laptop not powering on. After getting the original dump I tried a clean bin for a T470 found in the forums and after flashing I had the power on issue. I flashed the original bin back but no luck. Any idea's for the power on issue? I have unplugged the internal battery and the cmos battery as well but that did not help. I will get the indicator light when the power cord is plugged in and the power button will flash a couple of times but that is all.

                        Thank you for the patched bin!

                            Hi there,

                            I have a supervisor password on my T470, I´d like to get removed. I extracted dump file with a CH341 reader and used AsProgramm 1.41.

                            May someone help, please?

                            Kind regards from Germany!

                                Hello, I have a T470 and don't have the BIOS password, and need to access it to be able to boot my notebook (it isshowing me an error in the boot and forcing me to enter setup to fix it, but I can't enter and consequently cant boot).

                                I don't have knowledge of what tools (software and hardware) I need to access it and read/write the BIOS and how to remove this password as was mentioned before in this post.

                                Can you, or somebodyelse here, send me any tutorial or teach me how to identify the correct chip in my motherboard, read the information, dump it to be able to send here or to manually remove this passaword (or identify it in side the dump to be able to use to login)?

                                          Lenovo Thinkpad T470 20JM Supervisor password

                                          Hi

                                          I have a 2017 Lenovo Thinkpad T470 20JM i5 6200U 2.3GHz with a bios/uefi supervisor password

                                          Could someone please assist with password removal

                                          I have read the bios/uefi eeprom with the CH341A usb programmer & Asprogrammer & it displays these in this order after the read:

                                          W25Q128BV (WINDBOND)
                                          W25Q128FV (WINDBOND)

                                          I have uploaded a picture and the 3 files in a zip
