Warning
Power Management Extensions execute within the context of the core Power Manager, and can have a significant effect on overall system performance and security. Errors in a PME can block the core Power Manager thread indefinitely; this can cause the system to stop responding. Performance issues in a PME can harm overall system performance. Security vulnerabilities in a PME can increase a system's vulnerability to malicious attacks.
