No screen, No keyboard, No trackpad
I was given a macbook pro 13" early 2011 that was dropped down cement stairs. when turning on I heard the Hard drive clicking, No screen but the screen is not cracked or scratched. So I hooked it to an external monitor, the ? mark blinked and I installed a new hard drive. I down loaded mountain lion and she is alive. The following is not working. Keyboard is not working, I am using a blue tooth keyboard, trackpad is not functioning, I plugged in a mouse. Sound and internet is working just fine. I checked the ram took them out and reinstalled and it is registering 4 gb as before only 2 gb. Battery seems to be dead so to use the mac I have to keep it plugged in. I check all the wires and cables and they all look plugged in and nothing amiss. I did disconnect the screen plug and plugged it back in and when starting up the screen lights up then goes off. Could the battery be the reason for screen not working? Is it the logic board that is damaged and if so where do I send it for testing. I do appreciate your help.
Is this a good question?
