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

Why does the HP monitor keep entering save mode?

The main reason why a HP monitor keeps entering save mode because of a loose HDMI cable, a faulty battery, or an outdated BIOS.


The output device and the CPU are connected with the help of a thick HDMI cable. On the head of the cable, there are some screws. When they get loose, the monitor keeps entering power save mode.


Possible Causes 

  • Faulty batteries
  • Dust buildup
  • Outdated BIOS
  • Overheating


Faulty battery

Your CPU comes with a round battery that is responsible for the running of the system. When it has completed its life, it starts recording performance issues – one of which is your monitor’s slip into power save mode. Get your battery replaced if your monitor keeps entering power save mode.


Dust buildup

Is your computer close to a window? In that case, dust or other dander may get into the monitor, resulting in dust buildup. These particles mess up your device’s delicate system, resulting in your monitor’s constant slips into power save mode.


Outdated BIOS

BIOS needs constant upgrades for it to perform well. If you haven’t installed the available updates, you may incur the problem of your monitor entering sleep mode.



Your computer’s internal system is quite delicate. It can run for hours, but it is not advised to keep it running non-stop for long hours. Overheated computers stand the chance of crashing, resulting in the loss of work. Systems often signal some devices to go into sleep mode to prevent the system from crashing.


Age errors

Monitors have a set of capacitors that go bad after a certain time. If your monitor keeps getting stuck in power save mode, it is best to get it checked by a computer expert. Getting the monitor’s capacitors replaced – or replacing the whole device – may be a good option.
