Responder a:smartphones/tablets repair training needed in the United KingdomI am certified repair technician and work for myself as well as a company called iCracked. iCracked has training videos available to watch to learn how to do the repairs. There are also many other videos out on the Net that are very helpful. I also have some .pdfs that may be helpful for you if I know which models you want to work with. Each model is different so it is important to make sure you are looking at the correct one for the device you are working with. It is also imperative that when you are working with these devices, you take care not to damage any of the tiny flex cables or their sockets. Let me know if there is something in particular you would like to view.
Responder a:MacBookPro does not power up on AC power or battery.I also have a 2007 A1226 and had the same problem. It turned out to be the logic board. I am a certified technician so was able to diagnose it myself. After trying the hard reset (removing battery and unplugging from power, holding the power button down for 30 seconds, replacing battery into its place and plugging it back into power) and getting nowhere, I ordered a used and guaranteed working board from eBay for about $119.00, my Macbook Pro was back up and running with no more issues. I am still using it. In fact, I just upgraded the RAM to 4GB and it doubled the speed. Chances are, your logic board is bad.
