(SOLVED) Why Acer Monitor Keeps Entering Power Save Mode?

Why does the Acer monitor keep entering save mode?

The main why reason your Acer monitor keeps entering power save mode is because of dust buildup inside the monitor. The device has tiny holes that let dust and other debris pass through them. Other reasons include loose cables, overheating, or bad capacitors.

Possible Causes

  • Loose connections
  • Drained-out battery
  • RAM issues
  • Overheating
  • Bad capacitors


Loose cables/ loose connections

Computer users know that the backside of your PC is a jungle of wires. All sizes and kinds of wires from different devices connect to the CPU. But there are chances that some wires may loosen or get disconnected. If you encounter a problem where your monitor goes into power save mode, you first need to check whether its wires have been loosened.

Drained-out battery

Drained-out batteries are one of the major causes behind your computer’s unsatisfactory performance. If the monitor slips into power save mode quite frequently, it is best to get its battery replaced.


RAM issues

RAM sticks allow computers to run several programs simultaneously. But sometimes, the programs are beyond the sticks’ capacity. When that happens, the system crashes continuously. To save itself from irreversible damage, the monitor goes into power save mode and remains stuck until the RAM issue is resolved.



Your system cannot run non-stop as this may lead to overheating. When the system’s fans take extra time to cool off the heat generated through a PC’s continuous use, the system shuts down on its own to save itself from damage. It is also a reason behind your monitor slipping into power save mode.


Bad capacitors

Capacitors in your monitor can go bad when there are completely worn out. It forces your computer to go into power save mode. This problem means that your device needs a replacement. 


Dust buildup

Dust or debris inside the device affects its performance. Your monitor may be slipping into power save mode because of debris inside it. Regularly cleaning the device helps fix the issue. Users can do the cleaning themselves, but it is advisable to take your device to a customer care shop (offered by your monitor manufacturer).
