The Blair Ellsworth - Sep 14, 2020 post to this discussion adresses the "battery recognition" issue for me. That posting should be part of the page documentation IMHO. Thanks much Blair & You too Sarah!

Is there a BIOS patch or some kind of software tool to get the system to not reject the battery? I have system LED bliking on the front of the laptop (1 amber 1 white over and over). When I get into the unit, diagnostics warns me that the batter installed is not a Dell battery and will not be charged by the system. I have replaced CMOS as well.

I have updated BIOS on the unit to 2.20 from May 18, 2022 and it did not help.

Anyone want to buy a complete set from me? I can't even get past the first step to create the gap, tried for 2 hours already... Also the images dont cover what the "tesa" sheet is with all the pre-cut elements, event the secondary guides. Seems like what is shipping today doesn't align with what the guide is covering for a Pixel 3 XL
