I have my tablet a little while now and had a fair few problems with it, I thought i might share with you how to fix these issues, you may have one in a cupboard or draw nor working, well with this you may be anle to get it out and start using it again.
I have included a couple of pictures to help with the explanations.
Q, Tablet not turning on seems dead even when plugged in, or not charging properly.
A, The connector for the battery is a bit cheap and comes loose, I have had this problem 3 times now with 2 different tablets, just needs pushing back into its fully seated position.
Q, The screen Not working, Can see the backlight, the touchscreen and bottom buttons seem to be working but no LCD.
A, This one is a pain, happens all the time, if you drop your tablet, falls of the sofa, or place it down hardish, this can happen, The battery is glued/ double sided taped to the screen LCD for some reason, the battery is quite heavy and the lcd connection not the strongest so can be pulled out very easily by the battery, I have placed a small piece of sticky back foam on the back of my battery so that when the lid is on the battery does not move and has cured this problem.
Q, Get it in Bits / Take it Apart
A, 2 screws on the bottom under some rubber lugs, remove those. The rear of the case then slides upwards, it is very tight and takes alot of jiggling, dont try and force it open at the sides it wont work it will just break the case. It slides up about 2-3mm, then just lifts off from the top first.
Thanks Hope this helps others out.
thx for the info

Just repaired my mothers 7C G2 that means: I got hold of mine again (I went to her and gave her mine, as she doesn't have a PC, so that she still could check their stuff). The ARNOVA crew then send me the wrong letter (wrong Device ID on it) and returned the tablet unrepaired as 'wrong tablet sent in'. Grrrr
But now I 'repaired' it myself.Thanks alot 😀
Is it possible to replace the battery ? and if so what is the battery`s replacement number and is it a very tricky thing to do ?
Thanks in advance
I don't think the tablet is meant to be open so the battery normally cannot be replaced.
You can still probably do it yourself proceeding carefully when opening the tablet. I don't think there's a "known" part number for the battery, I can just read 3.7 v and 4000 mAh on the first picture from lordmpl (post #1). You'll need more details specially the connector format and the battery dimensions to make sure the new one fits in the tablet case.
Then you may be able to source one from Ebay or resellers in China...

I looked online for a replacement but could not find one. Removing the old battery you have to be very careful, as the double sided tape sticks like proverbial sh*t to a blanket, and connects the battery to the rear of the screen and more importantly to the ribbon cable that connects the screen to the mainboard. Be super careful and patient when separating the tape from the ribbon cable. I took mine off then used isopropyl alcohol to remove the gloopy tape/glue from where the battery lies on the ribbon. I find that the battery stays in place happily with just a bit of the tape at the opposite end. I have a spare battery but I'm hanging on to it in case mine dies.
I've a stripped 7C G2 with a dead mainboard. I have not been able to source a replacement, so I'm in the process of breaking for spares. I have a buyer for the screen. I'm happy to sell the battery for a small fee, if you are happy to go with a used one. I'm not looking to make money, just hassle costs really. Are you able to fit it yourself? It's tricky in that the battery is taped to the screen ribbon cable, and inevitably removing the battery pulls the ribbon cable out. Not too tricky if you are OK with a screwdriver. For me the hardest bit was removing the back! Once inside, not too bad.
I'm keen not to be seen using this as a trading area, so I'll PM you and we can agree something. Regarding disassembly - remove 2 screws from the base adjacent to the USB socket. The device splits in half - the rear panel slides up - imagine you have one hand flat on the screen, and the other hand flat on the back, and you apply pressure and slide the back panel upwards away from the USB port. It is difficult to slide in the first instance, and requires patience and application of pressure more in the centre of the back panel. You'll find your own way but essentially you are looking to slide the back panel not more than about 2.5mm, then lit will be ready to lift off. This is actually the hardest bit. Once done, you'll see the battery but it'll not just lift out. Rather, you need to remove the ring of screws around the edge of the secondary internal cover (about 10 screws?) and prise it away. The issue is that the battery is stuck to the back of the screen with double sided tape, and the tape runs across the ribbon cable that links the screen to the mainboard. Unplug the battery via the white plug with the 3 wires. When you try to lift the battery, it may drag the ribbon cable out of its socket. So you need to lift the battery firmly so as to prise away from the tape, but very carefully, keeping a finger on the ribbon cable to try to keep it from lifting upwards. You'll not know if you have been successful until you put the battery back in and see if the screen works. My approach is to remove the sticky tape (using isporopyl alcohol from Maplin) from the area where it lays onto the ribbon then it is much easier next time around. If you are unlucky and the screen ribbon is dislodged then you have a bit more work to do! But that's perhaps for another post - it is slightly trickier in that there is a risk of breaking one of the tiny plates that hold another ribbon cable in place. It's all quite doable with a bit of patience.
