Hello! Good day! Does anyone own the technical manual of this tablet? It seems that the battery reached the end of its useful life and it is necessary to replace it, but I do not have the technical manual to know how to disassemble it to make the replacement ... The fact is that apparently it has only 7% battery, I put it to charge with its original charger and after a minute it marks me 95% charge, I disconnect it, not even 2 minutes pass and it marks me that it has between 5 and 7% charge ... Salu2! : D
