Thank you for the post! My laptop battery is totally dead, not charging at all at 0%, so I cannot disable the built-in battery. Since it immediately dies if unplugged, the built-in battery is automatically enabled while it’s turned on and plugged. Can I just let it unplugged and proceed?

You should still be able to access BIOS with the laptop plugged into its charger to disable the battery before unplugging it and removing it. However, if that does not work, just be careful not to bridge any of the pins the battery connects to on the motherboard and everything should still be fine.

The X1 g.7 has a known bug where internal battery stops working (won’t charge, or says battery not detected in windows). I have personally solved this problem on 4-5 laptops by disconnecting the battery (follow this guide until step 4) and then plugging it back in after ten seconds. In 90% of the cases this has solved the problem without battery replacement.

After replacing battery in X1 Gen 7 battery indicator shows 100% (laptop plugged-in) and Lenovo recalibration function stays forever in Step 2 (drain battery down). If I unplug laptop, it immediately goes dark as if it has no battery and won’t boot. Plugging it in again and powering up everything works fine. In short, works when plugged in and doesn’t work when unplugged despite diagnostic saying battery is good. Any suggestions? Thanks.
