回答“My Acer Iconia Tab A500 won't turn on.”Could be the battery, the software or the mother board. If it won't charge you might try replacing the battery, and if that doesn't work, head over to the troubleshooting page.
回答“The power button won't work.”Either your power button is actually broken, or something like the battery died. If it won't turn on even when plugged in, it is likely the first issue. Unfortunately, the power button is soldered to the motherboard, so unless you're good at soldering, you may have to purchase a whole new motherboard. You might try and find the reset button hold it for a bit.
