I have the exact same problem. New battery, overnight on the power cable, boots up fine. Then after a few seconds, and with the battery status showing 100% it declares low battery and the excess heat icon before automatically shutting down. It does not display the behavior in Safe mode, but I can't check the battery in that state so I don't leave it running for long.

Has anyone else out there encountered this after replacing a Lenovo Yoga Book YB1-X91f Windows 10 battery?

Your battery is not Lenovo offically. It only works on android yogabook(yb1-x90f). You can rename LenovoShutdownService.exe(?) on C:\Windows\system32 to prevent windows shutting down. But you can not charge your battery while windows is running. Charging battery only works while windows is not running.

But I found this battery on taobao. It can charge while windows is running. https://item.taobao.com/item.htm?spm=a1z09.2.0.0.46792e8d0NWTpv&id=652131598092&_u=aue0c7jeb27

scott_lai - great tips! How did you discover the workaround - and the alternate battery source?

Posting a progress report since soctt_lai's suggestions. I took his hint to disable the LenovoShutdownService, but rather than rename the executable, I simply disabled it in the Admin Tools/ Services list. I also managed to install the most recent Intel Battery Management driver dated 2017. After installing a YB1-X90F (Android) battery, it appears to take a charge, as I can leave it on the charger all night, and run unplugged all day without dying. The battery monitor doesn't know what the battery status is (reports 100% and never changes), but that may not be crucial if I am careful to keep it plugged in when I am not walking around with it. Also, with the latest Battery Management driver it appears to take a charge even when turned on (though I have no way to confirm that objectively).

I faced this problem too, It's because the Windows YOGA Book use different battery "fuel gauge" chip (bq27542) from Android Yoga book (bq27514). only thing to do is to swap the battery fuel gauge + protection PCB from one to another. I've made video about doing it here

I now have two Android batteries and the defunct Windows battery. I am ready to try moving the Windows battery controller PCB to one of the Android batteries, but I am having trouble following your video. Do you have a slowed-down version, or could you describe what you are doing? Thanks.

This is quite complicated. I'll try my best to explain everything including the small details.
Tools
- Flat head screwdriver (for prying battery taps)
- Soldering iron, solder lead and flux (for soldering everything back)
- Multimeter (for checking the battery polarity)
First thing you need to do is to remove the protective masking tape that protect the battery taps. The use you multimeter to check the polarity of each battery cell (don't forget to use some marker pen to mark the polarity). Next use flat head screwdriver to pry off all of the welded-taps until they all came free from the board, do the same thing with both Android and Windows battery. Then swap the battery cells. Before solder the battery taps back to the board. You need to make sure that when you plugged the battery board back to motherboard ,the battery is aligned with the board and the flat flex cable is lay flat like original battery does. IIRC the battery isn't align properly (maybe off by couple millimeter). You may need some thick wire to connect the battery to the battery board. After everything was set. Make sure that the battrry polarity is correct (iirc the battery of android version is flipped compare to windows version) and carefully solder the battery back to the board. After everythingwas done. Use multimeter to check the batter voltage again to make sure that there's no short circuit that cause voltage to drops. The put the protective masking tape back, put itbback the the Yoga book. Do not put on the keyboard yet then connect the charger and power it on. Let it charge up for a moment and drain it once. If you sure that nothing is off, you can later put the keyboard back in place.

That helps. What did you do with the two sets of black leads from the Windows batteries to the PCB? Do the Android battery packs not include those connections?

Sorry for a late reply.

Those things are battery thermal sensor. I just place it as close as possible to the battery.
