According to some forum postings, some users have reported increased CPU noise coming from their laptops after making the upgrade to Windows 8.1. We’re offering some fixes that might solve your problems
Windows 8.1 comes with a lot of software problems for new users, but apparently, it does some annoying things to the hardware, as well. Recent reports suggest that the CPU noise on some laptops is actually increase after making the Windows 8.1 update. One of the frustrated users is using a Sony VAIO Windows 8.1 laptop, he said the following:
My laptop is a Sony VAIO and is less than 1 year old. I am referring to fan sound, I had no problem before the update to Windows 8. I called Sony and they told me to contact Microsoft. I noticed my laptop too hot on the side where the fan sound comes. I am not using my laptop on a flat surface, I usually use a little piece of wood in the back to have a 30 degree angle. The fan stop if I restart the laptop, couple minutes after, it started again at full power. When I explained this to SONY, they told me to contact Microsoft immediately, there’s nothing wrong with the machine.
The higher noise level coming from the CPU fan has been reported on Microsoft’s support forums, as well as on the forum of other laptop OEMs. The fact that the CPU fan is generating more noise than before, is caused by increased heat of the processor. Therefore, Windows 8.1 is requiring more CPU power which causes a temperature increase.
The Windows 8.1 system requirements aren’t that strict and they don’t require a lot of power or space:
- RAM: 1 gigabyte (GB) (32-bit) or 2 GB (64-bit)
- Processor: 1 gigahertz (GHz) or faster with support for PAE, NX, and SSE2
- Hard disk space: 16 GB (32-bit) or 20 GB (64-bit)
- Graphics card: Microsoft DirectX 9 graphics device with WDDM driver
Some potential fixes for the CPU noise in Windows 8.1
First of all, you need to make sure that Windows 8.1 is indeed the culprit. To do that, just clear fans carefully from dust so that you’re sure it’s not the dust that is causing the noise. After you have done this, here’s what one user is suggesting
If you run Task Manager and go to the Performance tab, you’ll probably see that the CPU utilization is really high (80-100%) for no apparent reason. Also, if you go to the Processes or Details tab, you’ll notice multiple instances of a process called “sdclt.exe” appearing & re-appearing every few seconds.
So, here are the steps that you need to take:
- Go to Task Scheduler
- Task Scheduler Library -> Microsoft -> Windows -> Windows Backup
- Disable the “ConfigNotification” task
- Restart your computer
Also, make sure you have the latest drivers installed. You could use the DriverBooster software to discover if you have any outdated drivers on Windows 8 or Windows 8.1. We also recommend this third-party tool (100% safe and tested by us) to automatically download all the outdated drivers on your PC.
