I've rarely used more than canned air. A toothbrush, like the ones for humans, canines and such could build up quick the ElectroStatic Discharge (ESD) so one last hurrah. Look up all resets about your model and give it a go.
So I'm afraid I've destroyed my MacBook pro (2011) by cleaning the dust off it with a toothbrush and vacuum cleaner.. I now know how stupid this sound....
It started out with me noticing a rattling noice from my MacBook when moving it around. My tech friend told me, he just thought something small had found its way into the laptop. He adviced me to open it when I got home, find the object obstructing the fan and remove it.
The following happened when i did as adviced:
1. After opening my laptop I moved my fingers gently with caution over the whole thing to find the cause of the rattling sound. Didn't find it, but the sound was still there when I moved my laptop from side to side.
2. Then tried by using a new (dry) toothbrush to gently brush the computer. Still to no effect.
3. So wanting to remove the dust anyway, I turned on the vacum cleaner on low power, while still gently brushing it with the toothbrush. Two small things got sucked up: One in the edge of the laptop, and one from the fan..
My computer wont turn on now, there's no response or any sound from the computer indicating any kind of electrical response.. After watching some videos of how I was supposed to do it, I realize how stupid i am..
Can you help me confirm if there's a any chance that I've destroyed either the electronic components or maybe caused a shortcut in the system? Or tell me how bad this is? Can I save my things or save the computer?
