Android doesn't respond. Detected by pc as several disks which need to be formatted

[Android Central Question]

Hello. Today I've been using my Zenfone max normally. But now it's all black and doesn't respond to anything. When I connect it to pc, it gets detected as many disks with this message: "You need to format the disk in drive LETTER: before you can use it". What can I do?

Welcome to Android Central! Did it suddenly shut off while you were using it? Plug it into a wall outlet and let it charge undisturbed for at least 6 hours. Then press and hold Power for 20-30 seconds. Does anything happen? If not, either the battery or the motherboard failed.
