Why is my tablet not turning on?

The narrow, inadequate, plastic switch may have shifted in its meager, very shallow nest. Which doesn't encompass the entire body. It appears to me as though the switch is slightly smaller than its holding pen. Or, perhaps, the pen is larger than the switch. Which ever the case, it should be seated snugly. Its function/design does not necessitate lateral movement, only forward then back to its default (neutral) position. It is a misalignment of the tiny "male" plastic protrusions of the switch and the soldering joints of the electrical connection. The "high points" or apex' are not squarely meeting (basically the "contacts"). Henceforth, theres not enough throw to amply register an effect, because they are meeting shoulder to shoulder rather than head to head.
