You can do this by connecting your laptop to an external display – a computer monitor or a smart TV works well. The only way to find out is to do a step by step inspection: Step 1 – Display Checkįirst and foremost, start checking the screen if it is truly the one causing the problem. Either one of the two is what’s causing the problem, and knowing which is the key to solving it. There are two primary causes: Motherboard has faulty hardware parts, or the LCD or LED is broken. That is to make sure what you’re experiencing is indeed a “no display” screen issue. Fortunately, there are also plenty of troubleshooting procedures you can try that might probably fix it.įirst of all, you should confirm that when you turn your device on, it powers up just like normal – power icon is lighting up, the HDD (hard disk drive) is running, and the fan is spinning. There’s a lot of reason behind this problem. Let’s start with one of the most common laptop screen issues – no display or blank screen. A laptop needs professional repairs to fix that issue or at worse requires consideration in buying a new unit entirely – which is most often the case.īut if you’re on a tight budget and you want to solve the problem yourself, here are laptop screen issues you may be able to fix. It isn’t the same when it comes to a PC where you can easily purchase a new monitor to replace the broken one. One of the biggest examples, which is our core focus here, is screen issues. Unlike a desktop computer where you can remove and replace damaged parts yourself, a laptop cannot. Unfortunately, there’s a catch, and that is a laptop’s nature of being a single unit. You can carry it anywhere and do whatever you want with it, from playing video games to showing an important presentation at work. However, one of the primary advantages that makes it a prime choice for most people (especially working-class individuals and students) is its mobility while packing similar performance of a PC.

Once you find the problematic hardware, open the Start menu and search for "Device Manager." Find the device in the resulting list-say, your keyboard-and right-click on it. Keep doing this until you find the offending device. If it doesn’t, leave one device plugged in the next time you put it to sleep. If you have trouble figuring out which device is the problem, remove all your USB devices the next time you put your computer to sleep, and see if it wakes up on its own. I’d bet dollars to donuts it's your mouse or keyboard-maybe your cat thinks it's a fun toy when you aren’t looking-but it could be anything. Windows may tell you a USB device is waking your computer, but you’ll have to find the offending device. In Windows 11, it's called Create Custom View.

If that command didn’t give you useful information, try this one: powercfg -waketimers In other cases, it may list a specific hardware device, and you can skip down to the relevant section in this article, or do web search for what settings to change on that device. In that case, your search is over, and you can adjust that program’s settings or uninstall it to stop the problem. For example, the last time my workstation woke up, it was due to my cloud backup program running its scheduled backup for the evening. If you’re lucky, it’ll give you a clear answer. Type the following command and press Enter: powercfg -lastwake Windows knows what woke up your computer most recently, so the next time it wakes up unexpectedly, open the Start menu and search “cmd,” then right-click the Command Prompt and choose Run As Administrator.
