I have a google Samsung S5PV210 Android tablet. A few months ago it started shutting off in the middle of doing something, powered up for a moment then shut down and now it won't power up at all. I've tried powering up through my computer but no help. I was told it needed to go back to the manufacturer. Where do I find their website to find where I send it? Will it be more expensive to fix rather than buy a new one? I did find a suggestion online to take the back off and remove then replace the battery, but I cannot get the back off the tablet. Thank you for your help. I'm at my wits end with this. Ready to give up tablets altogether. Thank you all for your input.
