I think the power button broke, & I have no Idea what to do.

The Ipad is in bad condition (IE: screen cracked, bottom glass is destroyed, but backlight is fine). Because of this some of the wiring is exposed and a friend was messing with it & messed with a little tab 2 inches from the bottom left, labeled "-2177-A' and then what I can barely make out to be "A.85:7 and then under the 85:7 "290" (also I am sorry if my description is bad, I dont exactly know how to describe it, on top oof the fact that I can barely see it). When she did this the Ipad's display immediately shut off and the power off sound played. When she couldn't turn it back on she used the power button, which produced no results (not even a sound). I was panicked and left it to charge for a night, and it was still the same in the morning. I was able to get it to turn on somehow while fidgeting with it, but when it is on the power button wont work to turn it on, & the only way I was able to do so was by messing with the tab that broke it in the first place. Now I am back in the place where it wont turn on & am asking for help on the internet. I hope that someone can help me with my issue :/
