Hello Aine,
Yes, I did receive an answer for my initial post, which I tried, but
what you have described isn't happening for me. After charging it up
full and using it until it dies, I plug it back in to charge, but the
gage isn't recalibrating, even if I let it charge full up again.
Does any one have other suggestions I could try, or should I take one of
the suggestions here and spring for a new battery.
Cheers,
Van

I thought someone already answered this a while ago? Try recalibrating
the battery manually. So charge it up to 100%, where the number
displayed when you press c in support information mode = the number when
you press d, (and yes-that may require a few unplugging/replugging ins
of the adapter), then use it normally till it dies. Then plug the
charger back in, wait more than one minute, and you should see in
support information mode that the battery has been calibrated (press a
to find out). Let me know if that works or not

Subject: [Braillenote] mPower battery calibration issue
Hello,
I'm intending to donate my mPower to a gentleman in Cairo, Egypt.
Before I ship it to him, I want to get the device in as good shape as
possible. so far, the only issue is with the battery.
I've been having trouble recalibrating it's battery. What I have done
so far is charge the device up to 100 percent, made sure all cards are
out, turn bluetooth off, and turned the volume up well above level 25,
and then I press space with o then space with i, then r.
The issue is that it never discharges all the way down, and instead
charges up again for a while, never to 100 percent though, and then it
goes back to discharging again. It continues this cycle until I
manually end the task. One time the cycle count indicated that it had
done 14 cycles. I thought leaving the mPower overnight would give it
enough time to do what it needed to do. Still, the battery gage is
inaccurate 1-5 percent with the same message that the battery gage needs
recalibrating.
Another issue is that, from a dead battery, it would fast charge up to
about 71 percent and switch to trickle charge. Coming back half a day
later, it still shows 71 percent with a trickle charging status.
Unplugging and plugging the power would get it fast charging again, but
it would switch back to trickle charging. Performing the unplugging and
plugging a few more times would eventually get the mPower up to 100
percent, but the gage still remains inaccurate and the mPower continues
to recommend battery calibration.
I have a theory that it might be the power adaptor, which isn't the
original one. Is the adaptor that comes with the mPower unique in some
way? If not, then what are the specs and requirements in a power
adapter that would work best? Perhaps I should purchase a BrailleNote
branded power adaptor and see how that goes. Or maybe a new battery is
in order. Would reinstalling Keysoft 7.5 fix anything.
I would appreciate any help this list could give me in getting my mPower
fixed up and donated to that gentleman in Cairo, Egypt.
Thank you,
Van
