Hey everybody brand new to the community so correct me if I make any mistakes. I have a Lenovo IdeaTab A2109 that I have had for right over half a year. I usually only use the tablet for school so it has been siting on the charger for most of the summer without being used. Well today I pulled it out to use it and it wouldn't start, it would only vibrate like it was going to start then flash a white screen then go back to black. If anyone has any ideas they would be greatly appreciated!
