after it died I just recharged it up until the steady red light turns to green so I unplugged it from charging and after that, I fold the keyboard and wait for around 20-30sec. but after I unfold it, it is not turning on, No light no indication or whatsoever, I try to charge it again and after like 3minutes the red light turns into green again so yeah I assume it is fully charge, is there any ways or is it possible to reboot or reset this keyboard?
