Hi I got a problem here,
I am running Ubuntu Mate v1601.
I have solder some single cell lithium polymer batteries to the VBATT connector. I left the system on overnight to let it charge. The next day, I check the percentage and it is still zero. When I unplug the system from the wall wart, the system runs for 1 minute and shutdown. Can someone please tell me what is happening? Batteries are 16Wh
We will fix it at the next version.
But now, you can use enclosed file.

Ignoring losses during conversion, I should get about 2 hours of battery life. I will test it with my 59 Wh battery pack.

I have test it. Results are still the same. The OS thinks the battery is 0% and it shutdowns...

So I infer that you added the driver for bq27441?
  1. > Add the driver of battery management IC(bq27441)
Copy the Code


Is there even a IC on the board?! The schmatics of both base board and core board does not show this IC?
LeMaker please respond if there is such an IC!

There is no such IC. But the gauge is built into the PMU. So the problem is either my board is defectiveOr the OS has a problem and cannot read the gauge.
