Dear all, I have PC with Windows 8.1 Ent., 32-bit, and Saphir Media Tablet with http://i.imgur.com/vEShkO5.jpg and Apps installed http://i.imgur.com/D8zyydM.jpg. Tab specs: Dual Core 1.6 GHz, 1GB, 16 GB internal memory, 3G. 1- Tablet turns itself off in standby mode occasionally and does not turn on. While battery was showing 70%. When I charge the battery in off mode it shows charging by turning on the yellow LED. When it is full charged yellow will turn in to green LED. But did not turn on. So I found a trick to turn it on. Press power button for 10 sec and wait. Then pressing again for 5 sec will turn it on. But I am still facing the problem. 2 When I see message 14% remaining battery, I plug the power in tab and suddenly it shows 50% and charging. See link above. DU Battery Saver app is installed now. I had Battery Doctor (Battery Saver) installed before DU Battery Saver. Both apps have the same problem. a- Is there any problem with this behavior? b- What actions should take to resolve it? Kindly help to resolve both of the above issues.
