Power Cover Not Charging 100% 0% 100% ???

I've seen many post, but no answers?  Surface Pro Classic and just bought a Power Cover.  Power Cover is recognized as both a keyboard and a battery under devises.  All firmware ever pushed is there and updated. Battery #1 and Battery #2 show in the battery menu...but not charging or maybe 100% charged is completely depleted. 

Once the internal battery reaches 80% (or so) the Power Cover charge goes from 0% to 100% and not charging.  Once the internal battery is depleted, the Surface shuts off and the Power Cover sits there happily doing nothing to help. 

Has Microsoft just ignored the many people that this problem has occurred to, or is there not a fix.  I'm trying to hold out till the Surface Go, but this battery thing is annoying to deal with.

Please don't add the gif. of how the batteries charge or how the blue fills the keyboard and monitor, please please don't answer with that.

    Hey are the tiny contacts directly connected to the batteries, would it be possible to charge without opening the unit?

    Thanks

    No, in fact the BMS/keyboard circuitry must check that the keyboard is connected before it activates those tiny contacts as there is no voltage present when you take the keyboard off the surface. I assume they do this otherwise the contacts could easily be shorted and cause a fire etc.

    In short, the only way to "wake" the batteries is to open the unit. Again have a good read on Battery university so that you fully understand what you are doing.

    Does it still work good? I have the same problem but I am not willing to do such an operation like you did! 

    Could it be that eventually the battery 'wakes up' by taking the charge or is it that boost is the only option to kick on the battery?

    It is working really well, I did a battery report after its first charge and it was showing higher capacity than what it was supposed to have :)

    No, unfortunately the battery will not eventually wake up as the voltage has dwelled bellow the BMS threshold voltage, as such the charging circuitry will not charge the batteries :(

    Bellow is an extract of the battery report that I did after the first charge, I haven't run one since as I have been playing with another keyboard, as such the report will be skewed.

    Thanks for sharing these pics (and the great idea). Did the fabric cover come back together neatly after your "surgery"?  I just don't want to wreck what is at least a working keyboard...
