And if this still doesn't work? What else can I try?

[scoobym0m]

My daughter in law has a samsung galaxy 3 tablet that stopped charging and wouldn't come on. I tried the reset, I've also disconnected the battery for 30 seconds and then tried the reset again. Now, I've totally replaced the battery...still no charge or anything. What else is there? This was a perfectly working tablet, then overnight it just stopped.

If you want to try and fix it yourself you can start by charging it with a different charger. If this doesn't work open up the tablet and change the charging port. I don't recommend this because you need to buy the parts specially and you need to have soldering skills. Warning this may be risky as you might damage the tablet and loose your warranty in the process. The safest route, if you have your warranty is to take it back to your seller. If you have the warranty they will try to replace it or fix it.
