Keyboard : replaced the logic board charging now working again

[grump_fiddle_reinstall]

Last summer the keyboard I was using with my PinePhone got very hot on the underside and stopped taking charge and stopped charging the PinePhone. I finally got round to ordering a new logic board for the keyboard and fitted it a couple of days ago. Charging seems to work now as it did before last years overheating event.

I noticed that the new board got quite hot whilst charging with a standard 2.1 A phone charger. Besides drilling holes in the keyboard case is there a simple way of improving cooling to the board (and where is the question mark when the phone is set to Swedish layout)

OK, battery life seems fine however, mobian seems to think that I have one main battery and two extra batteries. The second of the extra batteries is shown at 100% when full as is the main battery. But, as the first extra battery shows 0% all the time, the percentage displayed at the top of the screen is 67% when the two batteries are fully charged rather than 100%.

Which is logical if the OS thinks that my phone is connected to three battereis where one of the three is completely discharged.

Is this a reporting error by the OS or does the keyboard actually consist of two batteries one of which is not working?
