HP Pavilion - 15-cs0064st
Microsoft Windows 11

I have encountered a loud noise on my HP Pavilion - 15-cs0064st laptop recently. It happens every 1~8 weeks since the early this year.
The noise started before I updated to Windows 11 and has continued after I updated it. There doesn’t seem to be a pattern. It has happened from sleep mode, while I am using the laptop, and shortly after powering it on from off/sleep mode.
Previously, it only happened once every month or so, but recently, it has happened several times over two days. I have noticed that if I force power off the laptop when it happens and wait about 30 minutes, it does not happen again when I power it on. However, if I leave it, it will keep making the noise for about 10 minutes. If I power if off and immediately power it back on, it will make the noise again.

Please see the video of the sound for reference.

Please advise!

Thank you so much!

I would watch the video, if u upload it to youtube or dailymotion.

 

PS. without the video, I would guess it could be the battery or a coil whine (mostly a graphic/screen issue)
