Ally X not responding or turning on
Went on holiday with the Ally X to tunisia (I am from the UK) and it worked completely fine on the plane. I got to the hotel and put it on charge the 2nd day. It wasn't dead but it was on like 10%. The light was definitely on when I put it on charge to begin with. When I went back into the room a fair few hours later and I unplugged it, closed the case and put it in my bag. On the final full day I had an hour of down time so I wanted to use it. It wouldn't turn on at all. I assumed might have been dead but I plugged it into the wall and into my portable charger which output power draw and stuff and nothing. So it's not turning on, no lights are turning on and it's not drawing power. Spoke to AI and it said I will need to replace the device but at £800 I don't fancy that. I tried random trouble shooting steps, holding power button for 40 seconds and what not but nothing has worked. This was a few days ago now and I am now back in the UK but still not doing anything. Any ideas?
Edit: My boss held it the volume up and power for like a minute and plugged it into a 90w charger and it fixed it.
