Sorry didn't know where to put this, but i had to share what happened in my store today becuase it was so stupid.
Man comes in, says he might have damaged his machine becuase its not charging.
Take apart the laptop, and i find some kind of oil in it.
Gave him a call and asked if he sprayed something like wd-40 in it for any reason. he said "Not into the machine itself, but the hinges, i wanted to keep them from rusting."
