My Macbook air laptop sound, fan and speed is messed up, how do I fix it?
Where do I start. One random day I came home to find out that my sound has been muted. I tried to fix it with headphones, reseting the PRAM, google, and even by asking my schools computer tech. Some times the mute button would disappear and the sound bar would be in color but their would still be no sound. After the computer tech went on his account on the laptop to un-mute it, which he couldnt, he told me that my built in speakers dont work and would need to be replaced next year. Im like okay no problem, that same day i closed my laptop and found that the light was still on, I asked a friend and he said the black bar between the keypad and screen is what activates the laptop to shut off, which means its broken, so in between class periods i either shut down my laptop or put it to sleep. The next day my laptop starts to run slow and as soon as i power it on the fan runs immediately but the laptop isnt hot. My mouse moves at normal speed but my applications are running slow. This all happened in one week which is this week. My battery dies at a normal pace though.
More information
- This is a school given macbook air for a magnet program called iPrep, so i cant download anything with our administration password
- This is my second laptop out of the 3 years ive been in the program. My first laptop started to break after the sound got muted and my laptop ended up with an X on the battery and would only turn on when a charger is plug but would go super slow. This makes me scared cause i dont want that happening at all to this one.
Problems
- Sound is muted, it sometimes un-mutes but there is still no sound, internal speakers broken
- When closed the screen display is still open
- Computer applications go slow, fan turns on immediately
Any help, this is bothering me so much 😕
MacBook Air, OS X Mavericks (10.9.5), I have had this laptop for months
