                      Hi.
                      Can someone help me? Thinkpad T15 Generation 1 - the laptop turns on, charges the battery, shows no image. I have tried many bios, it does not even turn on on another bios. Only on the original bios it turns on, but as I wrote without an image on the display.
                      The laptop does not go through the POST procedure after turning on. It seems to me that these may be damaged built-in RAM, but first I have to rule out damage to the bios.
                      Could someone check my bios, or maybe someone can post a bios that works properly?
                      Thanks in advance

                          Thank you, but the laptop on your bios does not respond to the power button. I have already put too much work into it, the laptop is going back to the customer.​

                            Hello a question is possible to deactivate the 8GB onboard RAM in BIOS in a Lenovo T15 Gen1.
                            Otherwise there is probably no other way to reballing the RAM
                            Thank you​

                                      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?

                                      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

                                      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...

                                      Thinkpad T440P bios repair after WIFI whitelist mod
                                      by helpmepleasethanks
                                      As per the the rules, here are the specifications of my laptop :
                                      • Make and model number : Thinkpad T440P
                                      • Serial number (S/N) : PB-03A7V7
                                      • Model type - Model (MTM) : 20AW-S2N800
                                      • Bios version : 2.50 (not 100% sure, that's what I remember)
                                      Here is the problem, and the events leading to it :
                                      1. Upgrade screen, keyboard, trackpad, RAM and CPU
                                      2. Reboot and use the laptop for a bit : everything is working fine
                                      3. Shutdown (no power) and upgrade WIFI with unsupported chip (AX210)
                                      4. Boot up the device : bios warning, as expected
                                      5. Shutdown the device again (no power)
                                      6. Connect the 8-pin clip of a CH341a

                                      Thinkpad t480s, completely dead after BIOS flash using CH341A programmer
                                      by what_1282105
                                      Following this guide (https://www.reddit.com/r/thinkpad/co...g_and_flashing) i re-flashed my t480s BIOS using an external (CH341A) programmer. The flash didnt work, so i reverted back to my BIOS backup successfully. The BIOS in the chip and the BIOS backup file are identical according to windows' file compare. The revert, however, didnt work: the only thing the computer does is flash the power button 3 times when AC power is connected. I've tried unplugging the CMOS battery, holding the reset button and holding down the power button- no signs of life....
