If your MacBook Pro won't turn on, it could be due to a problem with the battery or a fault on the logic board. If it doesn't start even with the bottom cable, you'll need to test the hard drive, RAM and GPU. If not, just test the RAM and GPU. The reduced space and improved graphics of MacBook Pro Retina and MacBook Pro 15 can cause the part to degrade over time.
The LED screen of Macbook Air and Macbook Pro laptops is controlled by the logic board, so a failure of the logic board could affect the brightness of the screen. For Macbook Air and Macbook Pro users, an incredibly dim screen could also be a sign of a fault on the logic board. The new MacBook Pro includes 90 days of technical support and a year of limited warranty for hardware repairs. Replacing the MacBook Pro's logic board is a complicated process and should only be attempted by those with experience in repairing computers.
If your MacBook Pro or MacBook Air won't charge or the charger won't work, making everything work can be a race against the clock as your battery dies. The method you follow to reset the battery of your MacBook, MacBook Pro or MacBook Air depends on how old your Mac is and whether it has an Intel chip or an Apple chip inside it. If your MacBook Pro is relatively new, Apple may still cover the logic board repair service.
