Why does my Lenovo monitor keep going to standby mode?

Your Lenovo monitor is stuck on standby mode because of a loose monitor or HDMI connection. 


When your computer detects that no one is working on it, it signals the monitor to go into standby mode–it is also called the power saver mode, which allows your system to save some power usage.


Resolving this issue by following these steps:

  1. Unplug the monitor.
  2. Wait for at least 5 seconds.
  3. Re-plugin.
  4. Ensure that all cables are tightly connected to the monitor.


If the issue persists, the problem might be related to an integrated GPU. In such a case, your system uses an integrated graphics card. It can be resolved if you connect your Lenovo monitor to Display Port (DP)/HDMI connector or Digital Visual Interface (DVI). Also, it is important to check your PC sports. You may need an adapter to convert VGA signals into DVI or DP/HDMI if it has only a VGA port.
