laptop - Thinkpad X32 can't start on only battery

I've got a ThinkPad X32 that won't launch from just the battery, but will work if the AC adapter (or second battery from dock) is present; After launching the laptop, i can remove the external power source and run it just from the battery.


I've been probing around with my multimeter; I've checked battery terminals when the battery is unpluged and the adapter is plugged in (no difference if it's ON or OFF, always no voltage), four goldpins in the docking port that looked like they're transferring voltage (ON - with charger 16V, with only battery nothing; OFF - with charger 16V, with only battery nothing); Every measurement I did, I replicated on a ThinkPad X31 that can start from the battery just fine, unfortunately, every result was the same.


The issue most certainly isn't because the battery is bad - i've got three of these, and all of these work just fine on a ThinkPad X31.
