Did you get the dreaded Video Card failure message on your MacBook? You are still able to see this error message on your MacBook because it probably has two video cards. One is a basic one and one is a performance card. The performance card might have failed. This will mean that you can continue to use your Mac’s ordinary video card for basic displaying but you will run into trouble when you do anything more demanding, like even opening up Photoshop.
But, before you assume that your Video Card is down and out and can only be replaced, try this little tweak to see if you can bring it back to life. Sometimes, it is just a reset between hardware and software that will bring it back to life.
How to fix a video card that is not working in MacBook?
First, do a SMC reset. SMC stands for System Management Controller. If your Mac’s battery is removable, first disconnect it from the wall charger. Then, remove the battery. Once batteries are removed, press the power button and hold it down for 5 seconds. Reconnect the batteries and also the wall charger. Turn on your Mac like usual. To learn the steps for resetting SMC on a Mac that has non-removable batteries, please refer to this Apple guide here.
Then, do a NVRAM reset for good measure. To do this, shut down your Mac and restart it. As soon as it restarts, hold down Option+Command+P+R all together and hold it down for at least 20 seconds. If your Mac restarts while holding down these keys, you can let go. The best time to let it go is when you hear the startup sound for a second time since you started up your Mac.
These two resets will not delete any of your user data and can potentially fix your video card problems. But, you might have to reset things like sound volume or even re calibrate your resolution and reset your time zones as well.
If these two resets don’t fix your video card issues, run a Apple hardware diagnostics test as well. Use instructions provided in this Apple guide here.
