Answer to "Why won't my Samsung Galaxy Tab 2 7.0 turn on?"This can be resolved by leaving your Galaxy Tab to charge over night. If you let the battery run too "dry" ie. if you haven't used your table for a long time (6 months or more) the battery requires a long time to charge up. My tablet wasn't showing ANY signs of life before 2-3 hours of charging up, then it woke up and is now been working normally ever since.
