I pretty much sent my iPad to its destruction when I let my cousin borrow it over the summer. The screen is shattered and it won't charge when it's powered on. The only way to charge it is by plugging it in first while it's turned on and then turning it off. My cousin said the charging problem happened days later after she broke the screen. I'm not exactly sure how long afterwards but she said it didn't start immediately. I had planned on buying a replacement screen but now that it won't charge properly I'm not sure I still want to go through with this. I don't want to waste my money on the screen if it won't charge properly anymore. I just want to ask for some advice. Do you think the charging issue has something to do with the broken screen? Should I invest in a new screen? p.s. It's not the power brick or charging cable, those two are intact.
