My mid 2010 macbook pro 15″ unibody’s power button will not turn my computer on when shut off. I had this issue along with a few keys on my keyboard not working so I replaced the keyboard, twice. All 3 keyboards in total had this power button issue for the past 2 weeks (after a water spill). Apparently, the logic board was damaged by liquid.
Some Apple products contain sensors that respond when they detect temperature changes inside your system or device, turning on fans to bring cooling airflow to critical components.
If your device's processor is working on intensive tasks—such as compressing HD video, playing a graphics-heavy game, or indexing the hard drive with Spotlight after you migrate data—the fans run faster to provide additional airflow. You might hear fan noise when this happens, especially if you're in a quiet environment. This rushing-air sound is a normal part of the cooling process.
Ambient temperature, the temperature outside the device, also plays a role in the fans' responsiveness. If the ambient temperature is high, the fans turn on sooner and run faster.
If you hear the fans in your Mac Pro running at full speed and you aren't performing any intensive tasks, check the enclosure. Make sure that your Mac Pro is locked and fully seated, or that the top cover or access door is closed and locked on rack-mounted models.
Some Apple products have vents that let fans bring in cool air and expel hot air. Make sure that the vents aren't blocked to allow your device to perform at its best.
The surface your device rests on can block its vents, affecting fan behavior. If you use your device on a soft surface like a couch, pillow, bed, or your lap, its fans might run more. Using your device on a hard, flat surface like a table or desk is best for temperature control.
If the fans in your Mac run fast even when it isn't experiencing heavy usage and is properly ventilated, you might need to reset the System Management Controller (SMC) on your Mac. If you're experiencing this issue on an Apple TV 4K, Airport Extreme, or Airport Time Capsule, unplug the device, then plug it back in.

Every day is a great time to listen to your favorite tunes and some truly sick beats on your MacBook Pro. Out of the blue, however, you may find that your trusty laptop sounds unwell. Songs and videos coming from various apps and browsers, for instance, might sound terrible.
Audio issues aren’t at all a rare occurrence for MacBook Pro users. Users online have documented their issues with the MacBook Pro speaker, where they encounter a sizzling noise, speakers crackling, or a popping sound straight from the machine.
Here’s a quick guide to navigate these strange sounds coming from the MacBook Pro speaker and recover the good listening experience you’ve had before.
That weird noise on MacBook Pro can be caused by many different things, such as damaged or blown speakers, audio settings gone wrong, or a temporary issue that you can resolved when you reset the PRAM and SMC. After Apple released the MacBook Pro with a new feature known as Touch Bar back in 2017, forum users shortly came out to complain about a popping sound – their common denominator was owning the MacBook Pro with Touch Bar, albeit bought at different times and with various manufacturing dates.
It’s important to properly troubleshoot the sound problem to identify whether it’s caused by hardware or software, or if it’s merely a system update that can tackle the sizzling or popping sound. First, determine if it’s the speakers or the audio settings at fault. Plug in your headphones and start listening to anything with sound. If the sound comes across as clear on the headphones, then that means the problem is related to software. Blown speakers, for instance, may crackle at high volumes.
If your audio woes happen only while you play specific songs, videos, or other files, then it’s likely that the files are corrupted or suffer from low quality. If the problem persists, too, even if you listen from a CD or DVD and not directly from your hard drive, then you can proceed to troubleshoot the sound settings.
Before you try one of the fixes we provide below, make sure to always keep your MacBook Pro in tiptop shape by diagnosis your system regularly, cleaning out junk, and eliminating space hogs using a reliable Mac repair tool.
Here are some methods you can try to solve the sound problem on your machine:
Expect audio issues when the speakers on your laptop are set incorrectly in the preferences. Follow these steps:
Reset your Parameter Random Access Memory (PRAM) and System Management Controllers (SMC), which you can do by booting your computer while you hold down the Command, Option, P, and R keys simultaneously until you hear two chimes. Here are specific steps:
Some Mac OS X users reported hearing their speakers crackling after the 10.4.10 update, even though their speakers weren’t at all broken. To address this, update your OS to its latest version in order to patch any audio issues. Your audio woes might not be the result of your last update, but getting the most recent update just might be key to solving them.
Audio hiccups on your MacBook Pro can be totally annoying, but can signal a more serious problem as well. Electronics that produce a sizzling sound when electrically connected, for one, should be a red flag. It’s important to unplug it if it persists, remove the battery, and contact Apple support for assistance.
Otherwise, if you’re able to troubleshoot the problem more clearly, then you can try one of the three solutions we provided above and see if it successfully fixes that weird noise on your MacBook Pro.
