Hey guys, I'm having a little trouble with my g shock GA-100B which doesn't want to turn on. I left it in a wardrobe for month or two and I thought it needs just a charging, but I left for like weeks on a window it didn't turn on itself, I tried to press and hold all buttons but nothing happened. I have no clue if it needs new battery even though it's only 3 years old. If you have any ideas what to do i'd appreciate every single answer. Thank you.
