Help! Possibly bricked my tablet?

[muxi16]

I have had the p900 for about two years now. Rooted it some time ago and installed CyanogenMod without any problems. But just recently, when I tried to reset the tablet, it got stuck on twrp. I thought I would let the battery drain and see what would happen afterwards, but now I can't get it to turn on anymore, even though I let it charge. The tablet really doesn't do anything anymore, can't go into download mode and it isn't regocnized by my computer either. So I think it's bricked, but since I'm not really the most tech savvy person, I thought I'd ask here... Could anyone tell me if this sounds like it really is bricked, or if there is still hope?

I'm wondering if your battery discharged too far down, basically killing it. Once that happens, it no longer holds any charge. I've seen that happen on an older battery (actually happened on one of my laptops!). You could try removing the back of the tablet and disconnecting the battery and reconnecting it after a few minutes, then putting the charger back on and see if you get lights. (if you're going to do that, might as well have a new one in front of you and just replace it - easy to do, and Amazon has batteries for a decent price from a few different vendors - just did that to my Note Pro last week. Youtube it for directions, it's easy if you are patient. I used this one, http://www.amazon.com/dp/B00N4KRSVW and it is working well - even got rid of the flickering screen around 50% power and below...
