You MUST:- Provide the full machine model number, serial number (or Service tag, SNID) and the board model number (see https://www.badcaps.net/forum/showthread.php?t=88758 ) ,The serial number, make, full model number, motherboard model and revision (except QR codes) must be written/typed at your request as per the rules.

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

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 youComment

I tried SPD but didn't work. Do you know other method to disable onboard RAM? I'm going to remove RAM IC from motherboard but afraid that it can damage the board because of the black glue underneath .Comment

Hi everyone.
I have an engineering sample of a Lenovo ThinkPad X1 Carbon 11th Gen (TYPE 21HM-2FVT05, S/N PF-40G7CD) with an Intel Core i7 1360P (ES – Intel 0000). Since this is an engineering sample, the BIOS had a massive number of various settings. One day, I was experimenting with the BIOS settings and, after saving them, the laptop stopped booting and played a melody after pressing the power button, signaling error code 0002 (Internal bus error), just like in this post: https://www.badcaps.net/forum/troubl...shooting-lapto... -

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... -
Hello everyone,
I’m currently working on a dead MSI GP75 Leopard (MS-17E71) motherboard (i7 CPU, NVIDIA GPU) with a no display/no backlight issue initially. After extensive investigation, I’m at a critical stage involving EC firmware, BIOS/ME region interaction, and possible deep corruption. I'm seeking advanced insight from anyone with experience in EC/BIOS sync issues or PCH-level behavior. Here’s a full breakdown:
🧩 Initial Issue- Board powers on (fans spin, keyboard lights up and can be adjusted, caps lock led lights), but no display or backlight
- External display (HDMI) shows

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

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...
