The battery, which is not the original, but a replacement bought from China, is
bulging, and made the case to open.
There was no exact replacement. I had to desolder a chip from the original battery and solder it to the replacement. Not shown well in the photo, it is at
the other end. I added a close up photo of the chip.
-a-a The original battery was LP404252ARU, with three wires. One
-a-a for some sort of sensor. Device does not power up with two wire
-a-a batteries. On Aliexpres on 2020 I found a "404252 3,7 V 1200mAh
-a-a bater|!a recargable de pol|!mero de litio para Kobo Touch E-book
-a-a MP3 MP4 Lampe altavoz juguetes banco de energ|!a m||vil 404050".
-a-a The links from back then are dead now.
-a-a I have not searched yet.
I bought another reader a year ago, in May. A Kobo Libra Colour. This one the
company said they would process repairs. Perhaps means spares will be provided.
Perhaps I should do something to power up the old reader and do a factory reset, or something, in order to remove the DRM thing from it (you can only have six on Adobe Digital Editions)
(I don't see a group on epub or ebook readers)

Have you looked at the third (white?) wire to see what it may be "saying"? (i.e., if it is saying ANYTHING)
You could also monitor what happens when you impress a fake battery voltage on the B+/- terminals.

No, I cut the cables and removed the bulging battery. But I read somewhere it
is a temperature sensor.

For a book reader, it is a must. But I'd prefer standard AAA batteries or rechargeable equivalent.

Stops working. The seventh device is refused.
These things phone home before they authorize a device to read books.

Photos look like something more than just temperature.

I was bedridden from an injury, many years ago.-a Closest thing I had to a general purpose *big* eReader was a 12" tabletPC.-a As *I* wasn't moving, it was quite acceptable for it to be tethered to the mains.

Ah.-a My devices just read what's in front of them (also Adobe Digital Editions).-a But, I'm not sure how much of my content is protected by DRM. The "powered up" device, above, would then have to work well enough
to unregister itself?
On my ToDo list is a large (~14-15")-a tablet so I can read letter-sized documents "full size" as my library is increasingly "stored charge"
instead of "dead trees" (and, anything that I've scanned is, of course,
not DRM protected).
IMO, the biggest problem with eReaders is library organization.-a You
can't practically manage 1000 titles with their existing "book store" software.-a "Tell me which book/technical paper discusses 'foobar'..."

There is a chip with six legs, and another with also 6 legs, different form factor. The rest, no idea.

I read in bed, before sleep, and the usb cable on that thing is a nuisance while charging and reading.

Huh.
Once I organized my ebooks with tags for theme, and then came an update and killed all my data. Even what books I had already read. All appeared as "new,
unread".
You can search for a word-a (or string) on all your books. At least there is search, while there is nothing on paper books unless you write it down and organize it yourself, externally. Librarians know all about that. :-)

Either one could be an MCU.-a Or, some I2C device.

Ah.-a I either read "on the throne" or while waiting for appointments
(away from home).-a SWMBO has permanently "borrowed" one of my Nook HD+'s
OK, I actually prefer the Nook Color as it more closely resembles the "paperback" form factor.
But, none are acceptable for research papers and things that aren't
true pdf's.-a Hence the need for a 14-15" tablet.-a But, at that size,
it really needs to be lightweight (the 12 tablet PC that I previously
used was very heavy)

Yes.
So, just impressing a battery voltage on the battery terminals may suffice.

It's just hard to browse for titles, group them in meaningful ways, etc. These devices seem to be intended for someone who is reading one or
two books (novels) at a time, not as a "library replacement".

Yes.-a But, only applies to documents that are composed of actual text.
I often receive research papers that have been scanned and faxed.-a Even
if I OCR them, you lose access to annotations on figures, etc.
The world would be a better place if everything was created and distributed as searchable text.
[OTOH, I deliberately remove the electronic versions of the data that I
type into fillable forms to force folks to OCR them *or* manually enter
what
I've TYPED into them!-a (Why the need for the electronic form if YOU
have specified the typeface to be used in your electronic document?!)
If the electronic encoding and the grapheme forms differ, which does the
LAW recognize??]
