Current laptop : MacBook Pro (13-inch, Mid 2012) 2,5 GHz Dual-Core Intel Core i5. That could explain the temperature but I do not see how that could have possibly affected the display or the keyboard light. I am definitely using it for work - as I do illustrations, photography, photoshop, Final Cut Pro and Wordpress programming etc.
What I think could be the problem: when applying the thermal paste, I think I placed too much on the CPU, and the screws holding down the CPU could have been tightened up too tight. The keyboard light does not work, and the caps lock led appears to not be functioning either. The fan turns on, and starts spinning excessively fast, and the logic board also feels really hot.
After cleaning the top of the logic board, I proceeded to remove it to inspect the bottom side of it for any signs of corrosion, and whilst I was at it, I replaced the thermal paste on the CPU.Īfter reassembling the MacBook and reconnecting all the cables to the logic board, I found that upon pressing the power on button the display would no longer boot, it would just be a black screen with no backlight. Once opened up I found a lot of corrosion on the logic board and decided to clean it with Isopropyl 99% alcohol, with a toothbrush, applying minimal pressure. previously I was using MacBook Air mid 2013 with almost same configuration, only major differences is its SSD. This machine is very slow it takes few seconds to open application, few seconds to save a document. After booting it up a year later I found that it was running extremely slow and decided to perform an internal clean up. I bought MacBook Pro 13 inch mid 2012, processor 2.5 ghz intel core i5, 4gb Ram. About a year ago I had spilled some coffee all over my MacBook and it was left untouched.
