If you’re a MacBook user, this information can help you troubleshoot any issues you might encounter with your Apple devices. It applies to all MacBook Pro, MacBook Air, iMac, and Mac Mini models. While some troubleshooting steps may not work on certain models, they are safe to try and won’t cause any harm.
Random Shut Downs:
This issue can occur due to various factors, including hardware or software problems. If you’re experiencing this, try performing an NVRAM and PRAM reset, which can help resolve any glitches by resetting hardware components. Here’s the step-by-step process to do it.
To reset the NVRAM Mac, first, shut down your device completely. Then, turn it back on while immediately pressing and holding the Command (⌘), Option (⌥), P, and R keys together. Keep holding these keys for about 20 seconds, during which your Mac may restart. Once you hear the startup sound or see the Apple logo, release the keys. Your Mac will then boot up as usual, with the NVRAM and PRAM settings refreshed. This process can help resolve various system issues by resetting specific settings like volume, display resolution, and time zone preferences.
To reset your Mac’s battery, perform an SMC reset. For most modern MacBooks, shut down the device, then hold the Shift, Control, Option, and Power buttons together for 10 seconds. Release the keys and turn the Mac back on. For older models with removable batteries, remove the battery, hold the Power button for 5 seconds, then reinsert the battery and restart. This process helps fix power and battery-related issues.
Display Flicker:
If you’re experiencing display flicker, half-screen issues, or a dim display, it’s likely related to the screen itself, which may need to be replaced. However, since Apple displays are expensive, it’s worth trying this fix first. This process is challenging and requires tools, as you’ll need to open the back panel of your MacBook. Once inside, locate and disconnect the battery connector (you can refer to YouTube videos or chat with us on WhatsApp for guidance if you’re unsure how to do this). After disconnecting the battery, carefully disconnect the display cable or strip, clean it with a small amount of isopropyl alcohol, reconnect everything, and then try booting up the MacBook again. If you’re lucky, this might resolve the issue.
Battery Issues:
If you’re experiencing low battery backup or your Mac powers off when the charger is removed, it could be due to a bad battery. You can diagnose this by checking the battery cycle count and mAh capacity under System Information. If you’re already seeing a battery replacement warning under the battery icon, check the mAh capacity; if it’s still in good condition, you may be able to use the device for a few more months. Here’s a step-by-step guide on how to check the battery cycle count and mAh capacity.
To check your Mac’s battery cycle count and mAh capacity, start by clicking the Apple Menu () in the top-left corner of your screen and selecting “About This Mac.” Then, click “System Report” and choose “Power” from the sidebar under the “Hardware” section. In the “Battery Information” section, you will find the “Cycle Count,” which indicates how many charge cycles your battery has undergone. You will also see the “Full Charge Capacity” listed in mAh (milliampere-hours), reflecting the current maximum charge your battery can hold compared to its original capacity. Reviewing these details will help you assess your battery’s health and decide if a replacement is needed.
