My computer does not hold charge. This is my device, http://us.acer.com/ac/en/US/content/model/DQ.STPAA.001.

I sent it to Acer, but they could not fix it. They said this computer could lose 30% of battery charge if left unplug overnight. However, I found screen cause this problem. When I turn off a computer and connect HDMI, screen is still working. This device doesn't turn off screen. I upload a video. https://www.youtube.com/watch?v=jW-kmAxjKwI

I hope an engineer will fix this prblem.

    HoangDuocSu8548,

     

    Losing about 20%-30% of the battery if it is left unplugged overnight sounds about right for this Android unit. The approximate battery life while unplugged and being used is about 2 - 2 ½ hours, depending on usage of course.

     

    I'm trying to understand what you are talking about using HDMI on it. If you have an external device plugged into the unit using it as an external display that's going to use battery power if it's not plugged in. Maybe I'm not understanding what you are stating, if you could elaborate a little for me, the video you posted didn't really provide much clarity.

    HoangDuocSu8548,

     

    Another option you can try to conserve battery power while unplugged is enabling deep sleep mode to increase the length of time the battery lasts when the system unplugged.

     

    1. Launch the Settings menu.
    2. Select Display.
    3. Turn on Deep Sleep Mode.

     

    Deep sleep disables the following features:

    • System LED lights
    • HDMI auto detect when you power on the system
    • Automatic power on by real-time clock
    • Wake-on-LAN
