ThinkPad X1 Carbon 6th Gen (20KH) does not turn on anymore

#1 Post by npcap9000 » Thu Nov 25, 2021 5:03 am

I have a X1C6 that stopped turning on. It may have had an unexpected shutdown due to low battery SoC prior to the incidence.

This is the troubleshooting I've done so far:
  • When I press the power button, the power light on the left of the device flashes very briefly once, but inconsistently.
  • When attached to a power adapter, the power LEDs at the power button and the side blinks three times and then indicates charging/full charge with an organge or white light.
  • The BIOS chip has power and clock.
  • Continuity check on the flex cable pins shows the power button works.
  • Detaching other components does not help.
  • The usual tricks such as pressing the reset button or detaching/re-attaching the battery do not help.

If you can still get into the BIOS, try this.
To disable the built-in battery, do the following:
1. Restart your computer. When the logo screen is displayed, immediately press F1 to enter ThinkPad Setup.
2. Select Config ➙ Power. The Power submenu is displayed.
3. Select Disable built-in battery and press Enter.
4. Select Yes in the Setup Confirmation window. The built-in battery is disabled and the computer turns off automatically.

Now disconnect the charger and press/hold down the Power button for ~20 seconds.
Reconnect charger, try to boot.

Unfortunately, the screen stays black entirely.

[*]The BIOS chip has power and clock.
How did you determine the above to be the case if the screen stays black?
Collection = T430 - T500 - R400 - X300 - T61 (14" WXGA+) - R61 (15" SXGA+) - T60 - X40 - T43p - T43 - T42p - A30P
