Erratic Fans, Strange LED Behavior, and Power Issues
The System Management Console (SMC) is responsible for low-level operations that may not necessarily depend on the main operating system. These operations are performed before the operating system starts, and on an Intel-based Mac chip, controlled by the SMC chip.
If there is a problem with the SMC, you may encounter continuously operating fans, poorly functioning LEDs, batteries and indicators, or backlit keyboard that does not respond to the controls. You may also experience electrical problems, such as sudden shutdown and power outages.
SMC can cause problems with battery charging, lack of detection of external peripherals, and poor performance, even with low CPU loads. These problems are often annoying, but some can seriously affect how your device is used.
Fortunately, this fix is relatively straightforward; contact canberra computer repairs to reset your Mac’s SMC device.
Your Mac Forgets Settings
