Then, power it up again and — as soon as you hear the startup sound — press and hold the keys Opt + Cmd + P + R ( ⌥ + ⌘ + P + R ) all at once for around 20 seconds until you hear another startup sound. You should now be able to access your Mac normally without any further trouble or error messages related to malfunctioning NVRAM settings!
Boot into Recovery mode
Recovery mode is a built-in feature of macOS; it allows users to restore their Mac to the default factory settings. This is useful if there’s a serious problem with macOS and you can’t fix it any other way, such as if your Mac is having intermittent black screen issues or doesn’t display a black screen in safe mode. Booting an Apple silicon Mac into Recovery requires pressing and holding the power button; once you see the startup options screen, recovery mode will be one of the options available.
It should be noted that recovering your Mac to its factory settings is a drastic measure that should only be done as a last resort, after all other attempts at resolving the issue have failed. Additionally, doing this will erase any data on your hard drive, so make sure to back up important information first before entering Recovery mode on your Mac.
Repair Disk Permissions
Having a healthy disk permissions setup is crucial for proper functioning of your Mac computer.

To ensure the correct and secure functioning of all files and apps on your Mac, regularly checking and correcting disk permissions is necessary.
The easiest way to do this is using a Mac cleaning utility such as CleanMyMac X’s “Repair Disk Permissions” feature. This allows you to quickly identify any corrupted or errantly configured permission settings with ease and→ reset them in just a few clicks. CleanMyMac X has been called one of the best Mac cleaners for its comprehensive maintenance features, ensuring that the rest of your system remains safe and secure while resetting your disk permission with ease. Resetting your disk permissions with CleanMyMac X helps keep your system running optimally and safely at all times!
Liquid damage to electronic devices, such as laptop computers, can be extremely harmful and is a common issue caused by spills. Many MacBook users have encountered various display problems due to liquid entering their machine and getting into the wrong place. This often happens when the user is unaware of what happened and makes troubleshooting more difficult. To determine if your MacBook has suffered from any liquid damage, you should inspect for signs in three key areas: around the backlight circuit, the display connector, and on the TCON board. Furthermore, if there are any liquid damage indicators present near display components this is a good indication that some sort of spillage did take place.
Even though such indicators can give us an idea that something wrong may have transpired, it’s important to be aware that they don’t tell you the exact details of the situation or how severe it might be. Thus, it’s crucial that a professional technician assesses any type of MacBook displaying issues due to possible liquid damage before it is too late and further damages occur. Taking your laptop for repair quickly after noticing potential signs of harm may help you save money in repair costs and additional malfunctions down the road.
Boot into Safe Mode
Safe Mode for your Mac is a great way to troubleshoot issues and diagnose any problems that arise. By booting into Safe Mode, you can prevent other startup services from loading, which can cause problems for your Mac and its performance. This is especially useful if you’re experiencing issues with certain apps or launch agents behaving erratically.
To boot into Safe Mode, it’s important to power down your Mac completely first and wait 15-20 seconds before powering it on again. When the power button is pressed, hold down the shift key until the Apple logo appears on the screen. Doing this will start up your Mac in a safe environment where everything will load as usual, except startup services won’t be running so you can easily troubleshoot what might be going wrong without risking further damage. It’s also a great way to thoroughly clean out anything that might be hindering performance too.
Other MacBook black screen problems
When a MacBook Pro powers on but experiences a black screen issue, it could be an issue with the startup disk.

After that, turning on the Mac will determine whether or not the dark display issue has been resolved.
This method of force restarting works with many recent models of Macs. It is essentially the same as performing a hard reset on other types of computers; using this combo of keys helps to get rid of any potential hangs or software glitches that might be preventing an otherwise successful boot up process. This quick trick could potentially save users time and energy from having to take their computer in for repairs.
What is the relationship between preventing the screen from going black and battery life?
The relationship between preventing the screen from going black and battery life on a MacBook is directly tied to power consumption. When you prevent the screen from going black by using methods like playing videos, using third-party apps, or adjusting settings, you’re essentially keeping the display active for an extended period. While this offers the benefit of uninterrupted interaction and engagement, it also comes at the cost of increased power usage. The screen is one of the most power-hungry components of a laptop, and keeping it illuminated requires a continuous supply of energy from the battery.
As a result, preventing the screen from going black can lead to faster battery drain compared to regular usage with the screen allowed to dim or enter sleep mode during periods of inactivity. The extent of the impact depends on the specific method used and the duration for which the screen remains active. Playing videos or using resource-intensive applications for an extended period, for instance, will consume more battery power than using less demanding methods. It’s important for users to be aware of this trade-off and consider their battery status when implementing these methods. Balancing the need for extended screen activity with the desire to conserve battery life is crucial, especially when using these techniques for longer periods away from a power source.
