Restoring the automatic tablet mode switching is as easy as 123 with a driver backup after a clean install.
Download and extract my backup: https://www.chinamobilemag.de/tutorials/downloads/download/25-teclast/46-teclast-f5-treiber.html
Open the folder and go to SoftwareComponent/HingeAngle Device/. In there right-click on the “OEM40” file and click “install”. Now reboot and automatic tablet mode will work.March 19, 2017 at 12:17 pm #63694I doubt it will fix it since the charger is just a very simple power supply. You should measure your voltage. If it is less than 12V the charger might be the issue. If it is 12V replacing the charger won’t help.
Another thing you could try to calibrate the battery is to let it run to 0%. And I don’t mean on Windows, since it shuts off before the battery is completely empty. Start the UEFI menu and let it run empty in there. You could also try restoring the UEFI factory defaults just to make sure some setting in there isn’t screwed up.
If all of this doesn’t fix the problem, there likely is no way to do so. But really, the battery life of the EZBook 3 is awesome so the few percent missing won’t have a big impact on battery life. If the battery really is charged to 82% and it’s not just a screwed up display, it might also extend battery longevity.
March 18, 2017 at 10:25 pm #63685Try to open the laptop and unplug the battery from the mainboard for a minute. This will reset the Power Management IC and might fix your problem.
March 18, 2017 at 10:22 pm #63684Could you please share how you managed to boot Linux? On my unit I can not boot anything else than Windows. If I try to do I just get a black screen with a white cursor. I have tried everything already without success, even starting GRUB manually from the UEFI Shell results in the black screen. Secure Boot of course is disabled.
