You sit down at work and start-up Word or you launch your favorite game — only to find your screen has gone black. Why is this happening? Is there something wrong with your computer? Are you tired of staring at the black monitor when it goes to sleep? If so, read further…you might be able to save yourself some headache if you know why your computer goes into sleep mode when you use it.

While sleep mode can help conserve power, sometimes computers will go asleep regardless of whether they need to or not. This may happen due to an issue with your display settings (which we’ll get to below), but it could also be caused by malware. We’ll show you exactly what causes your computer to turn off its display when you try to open programs, as well as how to stop it from doing so automatically next time you boot up.
In any case, let’s take a look under the hood first.

Why Does My Computer Go To Sleep?


Most modern operating systems have pretty smart battery management features designed to make sure nothing runs amiss and the sleep feature is one of them. For example, macOS Sierra introduced “Low Power Mode” which turns off unnecessary background processes to reduce overall energy drain. It still allows apps like Mail to run, though. So even if your laptop isn’t running low on charge, it may still choose to shut itself down to preserve power.

Windows’ own system-wide Low Battery Notification appears every few minutes and shows you how much charge remains before shutting down. In fact, many laptops now don’t even allow users to manually switch into hibernation mode unless it detects a critical amount of remaining power. That said, you can always force shutdown manually via File Explorer’s View tab.

What about desktop PCs, though? Many of them simply aren’t programmed to give enough warning before turning off. The best way to check is to disable automatic sleep modes and see what happens. Some monitors do this too, making it difficult to tell what’s causing your problem. Even if your display doesn’t automatically enter sleep mode, it could be set to dim after 5 seconds anyway.

Also worth noting: Macs won’t go to sleep unless you specifically request it. They’ll just close applications. Still, if yours ever shuts down unexpectedly, follow these steps to troubleshoot sleep issues.
So why does your monitor say it’s turned off when it clearly isn’t? Read on…
