I Have an Android 4.1.1 Sensis N78 tablet that have a very bad (well that is what I been told in a previous thread in this forum) battery. It keeps tuning off the tablet 5 minutes after I turn it on. The solution, again as I been told, is to replace the battery. In the meantime I am wondering if I can run the tablet off the AC adapter without doing any more damage to the tablet? The reason I ask is that when the tablet is plug into AC it also charges the battery, and I just want to know what harm (if any) it can do to the rest of the tablet? Plus, I have found that if the recharge cable is not laying 'just right' the connection between the AC and the tablet is lost. And BTW does any possible problems also apply when I connect to my car via the lighter?
