    820-2330, usb drawing too much power message - REPAIRED

    I know it is an old device, but it is my device and I can't warrant buying a brand new macbook pro at the moment. Anywho I bought it with the usb ports not working/it giving the usb message on screen about 3 years ago and with the help of the movies Louis makes and this forum I have just...

    Agreed with Louis, manual testing is the only way in iPhone/iPad/iPod.

    HI, as far as I know there aren't any schools. All the skills and the knowledge I have I have taught myself. Everything I do is on YouTube. We mainly do iPhone/iPod/iPad, but I am getting into mac repairs as well, especially macbook air and pro by just putting my experience into them.

    how to get more motherboard customers?

    Like Louis says, find your niche. Get everything you do on Youtube and website etc... When I started out doing what i do now, after a lot of thinking I worked out - do what everybody else isn't.

    how to get more motherboard customers?

    Bit of a negative tint to that, but like I have seen you say in you movies, not many people make a firm decision to get into tech.

    I couldn't comment on anything in the US, but here in the UK I get the impression people can't be bothered/don't want to take the time to learn, but their loss is someone else gain.

    820-3115 starts from full battery 1/4 spin from empty or no battery.

    820-3023 2011 MacBook Air Ram Issue. 3 Beeps

    Question about the 3 beeps in that machine... In a macbook pro you could just remove the ram from, you could just take out the ram to find out which stick is a problem. Could you just remove the ram chips one by one to see if anything changes or do they all have to be on the board for the thing...

    I don't have as much experience as you guys on these boards, but I know you have talked about voltages so are you not able to measure where the voltage starts then stops or drops down then see what is between where the voltage is correct and where it is not? If you can do that, would tat give a...

    How to acquire and learn skills to use schematics!

    For me, reading them is knowing what the problem is you have then finding the beginning and end of a circuit you may be looking at and filling in the gaps of: does this work or does it not?

    What is meant by ripple?

    Just read the thread: [solved] 820-2936 randomly turning off after liquid Ripple is mentioned in it quite a few times so is it something you will see when measuring voltage with a multimeter or something you would see on an oscilloscope? Thanks
