What's the deal with residual power in electronic devices?
Just curious as to why the solution for many of these Samsung Tablets that, out of the blue, do not want to turn on, involves just removing the back cover and unplugging the battery and sometimes coupled with holding the power button down for 20 seconds or so, can magically bring life back to the device. Just trying to attain a better understanding of the nature of such issue.
Much appreciated.
Is this a good question?
