I have a macbook pro 2011 edition which i added 16 gb ram into it. i dont use it as a main computer anymore but mainly as a portable one. I dropped my phone on the top left of the keyboard while it was on and it started consecutively beeping 3 times (beep beep beep... beep beep beep...) until it shut off and restarted. i looked at apple forums and it should be fine but i just want to make sure its not going to spontaneously combust in my sleep. I am very experienced with hardware so dont bother trying to explain words, i know them.
