    The charging circuit is actually built-in to the tablet on the PC board AFTER the micro USB connector so removing the battery and connecting it directly to the 5V wall wart won't work. You may be able to find an actual 5v charger that will work but I don't know of any.

    The charging circuit or the regulator circuits? Either way, it brings up a good point. USB uses +5VDC. You need check the battery and make sure it is no more than 5V. Chargers typically output voltages that are slightly higher than the battery's rating. So while the USB charger should have a 5V output, it would not surprise me if the battery is rated ~4.7VDC.

    Charging, regulation and shutting down once the battery is charged to prevent overcharging are all functions of the charging circuit.

    If you lived in my local area, where I could see what needed to be done, I would do it for you. But since I live in the middle of the United States and you live in Spain, that will not work. I recommend you visit a local electronics repair shop. It does not have to be a computer shop. A TV technician could do it.

Hello, I downloaded Windows 8 the next day after it's release. It worked well for a week, but then soon after, every time I would connect my adapter to charge my laptop, it would hang. It works just fine without the adapter. I tried connecting another adapter and it would still hang. For now...
