This issue started abruptly a few days ago.
Basically, whenever I was doing something specific (such as booting up normal windows 10) a loud buzzing and glitchy sound would emit from my laptop before turning off. As well as this, whenever I unplug my laptop from its charging cable, it automatically turns off despite already being fully charged. This is not a power issue as Windows 10 boots normally if it’s in safe mode.
To elaborate more, these are the times I’ve reported hearing this sound and my PC turning off shortly after:
1. Booting into the windows Home Screen
2. Second part of the factory reset when the computer reinstall windows
3. Scanning for viruses using Malwarebytes while in safe mode
4. Having certain apps (such as Opera GX in my case) open
In addition to this, there are other ways I had tried to troubleshoot this:
1. Performing a factory reset (would always turn off in the middle of it)
2. Using the Dell Support Assist app that’s built in (no hardware failures were detected)
3. Deleting certain apps and disabling them from starting up
4. Changing UEFI firmware settings
5. Using Start-Up Repair
6. Uninstalling recent updates
This problem is too specific for just any google search, so I am hoping somebody here could help me fix my problem!
