I’m looking for advice on board-level troubleshooting and potential component-level repairs for a Lenovo ThinkPad T14s Gen2 Intel (i7-1185G7) showing multi-domain instability. Hoping someone familiar with this platform (or the related X1 Carbon Gen9/Gen10, X13 Gen2, X1 Nano Gen1/2) can point me toward the right section of the board to inspect, and whether any of the known fixes apply. Symptoms:


1. Trackpad (CS21 module) intermittently freezes during active use

• Not tied to lid open/close
• External USB mouse continues working
• Sometimes recovers with sleep/wake
• Looks like

Hi all,
I have a ThinkPad X1 Carbon 7th gen that stopped booting after a failed BIOS update. There is no life from the machine when the power button is pressed, but when the charger is plugged in, the amber charging indicator turns on and the power button blinks three times. The battery does charge, eventually turning the amber light white. I've dumped the BIOS and tried to fix it (but I don't know what I'm doing or how to use Lenovo's update files in this way) and even attempted to overwrite it with other uploads I've found here to no avail.

Hello! I need help getting a modified BIOS for my system.

Hi all, I have a Lenovo ThinkPad X1 Carbon Gen 7 type 20R1, motherboard model NM-C661 (which is why I believe this is the right thread despite being a Carbon).
The laptop lost power in the middle of a BIOS update and was (presumably) corrupted. Now it does not turn on at all (no display, no fan), with three flashes of the power LED along with an amber charging LED when plugged in.
