When I run FreeBSD 12-CURRENT r325397 on a HP EliteBook 1040 G1, the battery is not able to charge. If I plug in the laptop, "acpiconf -i 0" shows "high" even if the battery is not 100% charge, and it stays this way. To fix this, I have to reboot into Windows, and follow these steps:

To do this, I need to have a Torx T9 screwdriver handy to unscrew the bottom cover. CURRENT r324754 does not have this issue.

I will update a DSDT file shortly.

Since the DSDT file was too large to upload, I have uploaded to GitHub Gist:

Never mind. It does not exist on r326307.
