You havn`t given enough details so who knows ? , what are the EC part numbers , what are the motherboard model numbers . Try reading some of the other topics and use the forum search engine ,look for the motherboard model number and someone might have posted about their success or posted a guide.

Hello, I have one Lenovo T14 Gen 2 with a BIOS password and another identical one without a password. I have BIOS and EC programmers. Is there a way to unlock the password, or maybe I can read the EC from the unlocked one and flash it to the locked laptop? I also have two T14s Gen 2 units with BIOS passwords. Any help would be greatly appreciated.

I'm trying to revive a Thinkpad T14s Gen1 that seems to have issue with the power. Plugging in the USB-C charger the LED on the charging port doesn't lid and nothing happens if I press the power button.

Test conditions: board is outside the laptop, battery disconnected.

I made a number of checks already and found out that the ThinkEngine (page 94) does not set important signals such as M_ON that enable power rails such as 3v and 5v.

Hello guys!
Can someone help me with my Lenovo T14s gen 1? It have AMD Ryzen 7. Could need some files to start the process.

Thank you.

I have Lenovo with one BIOS chip Winbod 512 Mbit IC (W25Q512JV 3.3V).

When you switch it ON it delays power_ON and when it is ON it shows Reading ME Firmware. After that, it will say Failed to recover ME.

Attached is the BIOS BIN.

Board Number is JT4B1//JX3B0 NM-E091 Rev 1.0

Please HELP to Clear ME Region Firmware. I tried through software, and when the laptop is ON, it updates nothing. I tried updating BIOS still no LUCK.
