A few minutes after logging into Gnome I started seeing the blinking red light, tablet reported 97% battery left. I also found the tablet would not bother charging when plugged in at this point. I had these from the two i2c registers. sudo i2cget -y -f 6 0x34 0x82 0xf1 sudo i2cget -y -f 6 0x34 0x84 0xe3 Immediately after setting the workaround 'sudo i2cset -y -f 6 0x34 0x84 0xf3' the tablet stopped blinking and when plugged in after this it also appeared to charge. Gnome's battery icon changing to a charging one. I think this workaround fixes my issue. For my particular tablet seems things work best when '0x82' is '0xf1' and '0x84' is '0xf3'. -- You may reply to this email to add a comment.
