My tablet works fine with wall charger but does not charge the battery. The battery remains at 0% at all time. The tablet used to work as it should in the first week. Then suddenly the battery goes flat 0% and refuse to charge. From posts in various forums, the cause could be loose battery connections or under performing wall charger.
I cracked open the tablet and all its innards seems to be buttoned down tight. No loose connections or loose soldering. The battery wires connecting to the board seems to be fine and fitted tightly.
I used a multimeter to test the DC wall charger. Specs of the wall charger are Output: 5V 3.0A Input: 100-240V 50/60Hz 0.5A. I am not sure how to read the meter but I thought it showed 4.8v instead of at least 5.0v? Could this be the reason why my battery won't charge?
Can anyone with experience give some thoughts? Many thanks.
Update: SOLVED.
