When a laptop enters sleep mode, Windows automatically reduces background activity in order to save power. The device enters a low-power state by reducing CPU and other components’ activity, which should result in minimal heat generation. But, many Windows users have reported that their laptops heat up in sleep mode. If you happen to be one of them, worry not. You will learn effective ways to fix this issue.
When you are temporarily leaving your desk, it’s good to leave your laptop in sleep mode. You do not lose your work. But if the device starts overheating, things get really tense. The issue has been reported by users from almost all laptop brands including HP, Lenovo, Acer, Asus, Dell, and more.
A laptop may overheat in sleep mode because of the following reasons:
- Blocked vents: If you haven’t cleaned up the vents in a while, there may be a lot of dust and debris resulting in poor ventilation. When the heat can’t easily pass through the vents, there’s a high probability of overheating.
- Malfunctioning cooling system: The cooling system on your laptop may have malfunctioned. It may not be running when required, which could also result in the heating up of your laptop.
- Excessive background tasks: If the background processes continue to run even in sleep mode, the laptop may heat up. This could occur due to software bugs or glitches.
- Driver issues: Your laptop may have outdated or faulty drivers causing the laptop to generate heat even in sleep mode. You would want to make sure all the drivers are updated.
- Malware: If your computer has some malware, it will keep running in the background and generate heat.
Now that you know the reasons responsible for generating heat on your laptop, let’s start troubleshooting them.
6 Ways to Fix Laptop Heating Up in Sleep Mode Issue
If your Windows laptop is heating up in sleep mode, fix it by implementing the below solutions.
Solution 1: Check Your Laptop’s Sleep Settings

Expand Screen & sleep. Make sure, the device sleep timer is not set to Never. If so, the device will never go to sleep and the processes will keep running in the background generating heat.
Solution 2: Clean Up the Vents
When you face heating issues on your laptop, the first thing you need to check is the vents. The dust or debris accumulation may be blocking the vents. If so, the heat won’t properly flow out and your laptop will overheat.

It is advised not to place the laptop on a bed as the ventilation may not work properly. It’s recommended to keep the device on a table.
