Something happend with my macbook air can you help me like whenever i pick it up something under it clicks lik its broken or something??? what should i do!!

I'm not clear what "30 pin" refers to. It sounds irrelevant to your question or am I missing something?

Try this:
Go to System Preferences, click on Sound. Make sure you are on the Output tab. Select your device.

Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/mark_1e5d703456353ef9

A few ways of doing this

1) restart mac and press down the trackpad button after you hear the startup noise

2) if that does not work try opening up disk utility which is located in applications and then in the utilities folder and click on the icon of your disk under the left hand column then go up to eject button and click eject

3) or open up terminal found in the utilities folder within your applications folder and then type in drutil tray eject and then press return

4) Finally what to do is try pick up your macbook tilt the macbook to the one side and press the eject key and hopefully the effect of gravity will allow the CD to fall out.
However, I would say that DVD drives in all macs are a bit suspect and if your macbook is still under warranty or under AppleCare take it back to the Apple Store and tell them that the DVD drive is faulty and they should replace it free off charge. Hope this helps.

something could have gotten into the speaker and touch the membrane hence the crackling when the membrane moves around.you can try to blow it out with a compressed aire can. if that fails, would assume your speaker is broken somebody has to open the Macbook and replace the part. If you want to pay to have somebody do it for you there is a third party Macbook Repair Service. However, if you want to do it yourself, the part is available on ebay. Here's an Macbook Repair guide. Maybe a tech savy friend can do it for you.

I would check the energy saver settings under system preferences and see if it is set to go to sleep after a period of time. Also check the schedule button under energy settings to see if there is a scheduled sleep setup. Hope this helps

this would mean the blower motor is not working either because the blower motor is bad or the blower motor resistor is bad if you lost any speeds before this happend then you most likly have to replace the resistor this is located under the dash passanger side and is mounted in the heater box behind the blower motor (follow the wires from the blower motor to find resistor

that normally happend when the macbook do not find the software you can read this apple post http://support.apple.com/kb/TS1440

Click the Apple in the upper-left corner, then click System Preferences. Click User Accounts. Now, click the lock at the bottom if you need to authenticate and make changes. Highlight your name and click the Login Items tab on the right. Highlight Skype and click the minus (-) button. Now Skype won't start when your computer does. If that doesn't help, open your Applications folder and drag Skype to the trash to remove it from your system. If that doesn't help, something else is causing your computer to slow down.

Let me know. I'll monitor your thread.
