Hello,
first, i mua this tablet in january 2015.
i found out this device turns off by itself at 22% battery while using it(about a month ago) and now, it's powering off at 37% over and over. in order to power on, i have to plug in. if not, there is no way to run it.
i'm living in korea and asked for a chat service on the dell official website, but they just gave me an international number. such an irresponsible! it seems not like solving this problem.
Please help.
Thanks!
I didn't find the right solution from the Internet.
