Preventing MacBook from Sleeping when Lid is Closed: A Step-by-Step Guide
Understanding the Issue
Before we dive into the solution, it’s essential to understand why MacBook’s sleep mode might be triggered when the lid is closed. The primary reason for this issue is the Power Management System (PMS), which is responsible for controlling the MacBook’s power consumption. The PMS uses a combination of Power Management Units (PMUs) and Power Management ICs (PMICs) to regulate the power supply to the MacBook’s components.
Causes of MacBook Sleeping when Lid is Closed
When the lid is closed, the MacBook’s PMS detects the absence of a user’s presence and triggers the sleep mode to conserve power. This can happen due to various reasons, including:
- Incorrect battery calibration: If the battery is not calibrated correctly, it may not be able to hold a charge, leading to the MacBook sleeping when the lid is closed.
- Power management settings: The MacBook’s power management settings can be set to sleep the system when the lid is closed, which can be done through the System Preferences.
- Hardware issues: In some cases, hardware issues such as a faulty Power Management Unit (PMU) or Power Management IC (PMIC) can cause the MacBook to sleep when the lid is closed.
