The battery management chip (and the little green light) is under firmware control normally.
This isn't "normal" operation by any means.

*1* Open the case and disconnect the battery, NOW.

*2* Set up a serial port connection, you are going to need it.
For certain sure, your going to need it.

The Kindles are "dual system boot" computers, with very little shared between the two OS installations.
The pcbid, serial number, manufacturing code, etc. are some of the shared information between the two system installations.

Translation:
You have probably bricked both "main" and "diag" mode systems.

Congratulations, your right up there with the people who ask themselves: "I wonder what this 'Erase All' button does?" Just before pushing it.

(Hint, the label is descriptive.)

Once you have the serial port connection set up, then the next thing to do will be find out if u-boot still works.

Note: It probably does and also probably is refusing to boot either OS because of the corrupted hardware descriptors. The messages it puts out over the serial port will tell us a lot, so be prepared to capture them to a text file.
(The PW and the PW2 use different SoC chips, so swapping the hardware descriptors was doomed from the moment you thought of it.)

But let us know what you find out is happening over the serial port.
