My fully charged PS Vita started turning off while in standby mode, some time ago. When I turned it on, it asked me to set the time and date again. I noticed, some time later, that whenever I tried to charge it, the PS button would blink orange twice and then stop blinking, and the Vita wouldn't charge. A couple of days later, I couldn't even turn on the Vita anymore, not even with a hard reset. I kept trying and managed to turn it on some times - only for it to turn off right away. In a desperate struggle, I opened my Vita, disconnected the battery and connected it again - and everything started working again, for my relief. But now everything is happening again and, before opening it once more, I would like to ask if anyone knows anything about this. I'm pretty sure it has something to do with the battery, but as far as I know, Sony won't sell only batteries. (I don't live in the US and can't send my Vita to any tech support, before anyone suggests that.) Any help would be welcome.
