1 buzzing noise coming from fan when holding power button
hi guys
I have a clients 2012 12” MacBook Pro here, I have never seen an issue like this before.
What happens is if you press the power button once the processor fan shakes for a second then nothing, if i hold my finger down on the power button the fan will spin but nothing happens no lights no display or anything but also I can hear a faint buzz noise coming from fan area?
Things I have done already (removed hard drive, removed ram) still the same
Here’s a short vid of the issue: https://vimeo.com/533800594
Это хороший вопрос?

Given the systems age I would start with the basics, is the MagSafe charger LED lit and is it Amber or Green? If green move on to below, if not let the system charge or put in a known good battery (charged)
