Hello all,
My Spin-7 has been shutting down suddenly when the battery level reaches about 19%. Here is what I've done thus far:
* Performed the calibration procedure detailed here: http://www.howtogeek.com/172271/how-to-calibrate-your-laptops-battery-for-accurate-battery-life-estimates/
* Performed a battery reset (2X) by inserting a pin in the battery reset hole (bottom of case), and holding there for 5 seconds, then 30 seconds.
When the problem started the machine would shut off abruptly at 40% battery. Now it happens around 19%, after the above two fixes. But clearly this is not good. There are no warnings, the machine just abruptly shuts down, and will not power up again without plugging it in to the mains.
Critical and low battery levels are set to 5 and 10% respectively.
