Completely dead MacBook Pro, won't turn on.

Completely dead MacBook Pro, won't turn on. I was using this MacBook Pro. I bought it over a year ago (so no warranty anymore) at an Apple store here in South America. (EMC 2554, late 2012)

"The misinformation here is mind numbing.

a) It is the opposite - newer models will turn on with no battery, and when you plug them in they will turn on by themselves. Only certain older models required the battery to be charged to turn on.

b) No you do not BANG it to make it turn on, this is BS.

c) Measure PP5V_S5 and PP5V_S3 voltage rails."

I had same exact problem. Banged its corners against a table, and it fired right up. I bet it's connector corrosion.

"Well, I know it is bizarre but my relatively new (late 2015) MacBook pro failed on me twice during last month. In both cases, I became desperate enough to

A) buy a set of screwdrivers to open it up

B) send it to an authorised apple centre

But I did not perform above actions, instead, done the following that worked for me on both occasions. As said I had no option to try on and ALL other solutions didn't help me at all including resetting SMC. So what I did was, I put my hand on the keyboard with a gentle pressure and moved it from right to left, in a way that it pressed a number of keyboard's keys at the same time. AND IT worked !!! Whether there is a lose connection underneath OR the move triggered a specific combination of keys that has not been published, I do not know. But I do know it worked for me twice. So give it a try, it might help you too !"

"The newer machines do not come with a system installation DVD. Your machine shipped with 10.7.3 installed.

To reinstall the system or run Disk Utilities, start up holding down the Command and R keys.
