How to power up a dead MacBook

Hardware

A friend asked me if I could help out and diagnose why his MacBook won’t power on. I immediately peaked up and was ready to play. How could I resist the opportunity to test my diy skills and try to salvage his computer.

I know enough about computers to be dangerous. I would never claim to have more skills than the staff at your local Apple store. However, I do love the times we live in because everything is available online to discover the what, why and how to repair your tools.

During my browsing I discovered a sh*t load of how-to guides, so I said f**k-it and created one based on my research.

Workflow

Step 1:Power source

The first thing to check on your hardware are the power sources.
For example:

  • is the battery charged?
  • did you plug in the cord?

If you have checked these and you still have no power then it is time to get the tools and see what’s else can be done.

Step 2:Power Cycle

Basically you are just turning everything off and on. I learned how to do this from the crew at ifix. I dedicate the next part to my man Victor Clausson; you rock man.

You know when you have those long nights of drinking and your conversation skills are horrible. The best thing to do is go to sleep. You will wake up in the afternoon, completely refreshed from the previous nights fun!

  1. unplug the battery
  2. disconnect the power cord
  3. hold the power button for 10seconds
  4. keep holding the button and connect the power cable
  5. continue to hold the power button and count to 10
  6. release the power button
  7. power on MacBook normally

Do you hear the chime?

If you followed these simple steps and your Mac has juice again: Congratulations, You are a winner. I on the other hand did not have any luck with these steps. Now I must continue the journey to see if I can save the Mac!

 

How the CPU functions in a computer

Hardware

The brain of your box.

The CPU has been tasked with the responsibility of issuing instructions to the other parts of the computer.

Why you begin with the history of the word and cognitive synonyms?

The birth place of words are in peoples minds. They become the blocks we use to build what we see, hear, taste, touch and smell (our senses). When you read you are condensing your senses into a chain of links from a set of symbols. These visible symbols are the anchors you chunk into your vocabulary to name your thoughts and beliefs.

The purpose of reading a list of the history of a word is to build your relationship as the word grew-up in time. The family origins of a word connects the anchor to the chain of how the words story sprouted in someones mind.

The cognitive synonyms (synset for short) are the present sprouted offspring of the word. They provide you with fresh mental anchors to the chain of the words story.

Read the groups of words to see their birth.

Connect with the anchors to the story of the words to see how they’ve grown.

Basic Knowledge

CPU:
The central processing unit, aka microprocessor, carries out the instructions of a computer program by performing the basic arithmetical, logical, and input/output operations of the system.
Hard Drive:
A physical device in the computer used to store programs or data on a temporary or permanent basis.
RAM:
Random Access Memory allows stored data to be accessed in any random order.

Process

The workflow of a program when initiated:

  1. The program inititated is transferred from the Hard Drive to RAM.
  2. The CPU loads the program from RAM.
  3. The data that was loaded in the CPU is processed.
  4. What occurs in the final step depends on the program that was loaded.
    • example: running a word document, using software to edit pictures or a movie.
