    Look at chris review:

    “Intel Graphics power settings had all the power (crippling) features enabled on battery and disabled on power”

    I think you have to change settings of intel graphic driver

    What I've used and what I've got:
    TECLAST X98 AIR 3G, TECLAST X98 AIR II, TECLAST X98 PRO,CHUWI HI8, CHUWI HI12, CUBE I9

    All the settings are disabled, with the settings enabled on battery the screen would not turn on at all.

    The dimming of the brightness is usually done using a PWM method. full brightness usually means no pulses, but a solid signal. I would say this is hardware. The driver is not capable of making these chopped pulses. Correct me if i’m wrong about the above theory, but I expect it to be a hardware issue.

    It could still be a software issue. You can try by reinstalling windows 10, but I think it’s hardware. 🙁
    I hope my tablet doesn’t have this issue…

    When did you order the tablet? (could be a problem related to a certain batch)

    I ordered it a week ago.

     

    What kind of hardware problem could cause this? Any work arounds to dim the screen any other way? its really annoying

    Very odd, must have received a bad unit.
    

    Try this, hold the power button down for 15 seconds. Then wait 10 seconds, hold it down again for around 4-5 seconds. Any luck? If not hold the power button down for 15 seconds, then connect it to the charger and leave it charging over night and try again in the morning.

    I let it discharge fully almost. Plugged in the charger the lights started glowing, then I pressed the power button. After that the lights went off, and now no matter how much I charger it the lights will not turn on (led)… I put it on a cell phone charger 5v (after reading online) I feel the battery is getting warm but no signs of life. On the original charger the tablet is not even getting warm when charging
    

     
    

    which charger should i leave it on? i was reading online about trickle charge could help
    

    5v 1amp (usb hub) or the original charger?
    

     
    

    Now if all fails. can i try to charge the battery directly using 2 wires from usb port without unsoldering connections + -? or will it fry the board, and i must unsoldering the battery connections before charging directly?
