Not Operating after opening the case and cleaning the cd/dvd drive.
I opened my MacBook case to take out the dvd optical driver to clean the lens because I couldn't read or write cd.
After I opened the case and finished from cleaning, i returned everything back to it place, put I couldn't open the MacBook.
When i press on the power button, the display still black, and there is a strange sound about every 5 seconds. I waited for about 5 minutes and it didn't operate.
Please, I want to know if I did something wrong or if there is anything i can do to fix it.
Is this a good question?
