I haven’t turned on my MacBook Pro for 10 months and now it won’t charge or turn on.

My MacBook Pro uses the USB-C adapter. I have tested the USB-C cable and Charger and those are fine as they work with another device.

Anyone have any ideas on how to fix this?

Try resetting the SMC https://support.apple.com/en-us/HT201295

if no resolve Try resetting NVRAM/PRAM http://support.apple.com/kb/ht1379

If your Mac doesn't turn on
