Static or buzzing noise when AC adapter plugged in

[Spittdogg]

When my AC adapter is plugged in, a faint weird buzzing or static electricity type noise emits from the computer.

I've tried using a different adapter and a different outlet. Same issue... not even sure it is an issue, but I just bought the computer brand new last week, so if this is an early sign of an issue, I want to address it now.

Can you tell me what this could be and if I should be concerned?

Seems like the same issue described in this post: https://h30434.www3.hp.com/t5/Notebook-Operating-System-and-Recovery/Strange-noise-from-laptop/m-p/6...

Thanks

Thank you for posting on HP Support Community.
 

Don't worry as I'll be glad to help, I have a few troubleshooting steps we could try to fix the issue:  

Firstly, perform Windows Update and HP Support Assistant: (do not skip any troubleshooting steps if you feel steps are repeating) 

To check for updates now, select the Start button, and then go to Settings  > Update & security  > Windows Update, and select Check for updates.

Install updates from HP Support Assistant: Go to Download HP Support Assistant to install the tool.

1. To open HP Support Assistant, double-click the HP Support Assistant icon .
2. Click My devices in the top menu, and then click Updates in the My PC or My notebook pane.
3. Click Check for updates and messages to scan for new updates.
4. Review the list of updates. Updates with a yellow information icon are recommended. Updates with a blue information icon are optional.
5. Click the update name for a description, version number, and file size.
6. Select the box next to any updates you want to install, and then click Download and install.

Hope this helps! Keep me posted for further assistance.

Hello - I tried those steps. Everything is up to date with both Windows update and HP Support assistant. The issue still persists. Can you confirm what could be causing this noise when plugged in?

Hello,

>I just bought the computer brand new last week

if the device is new and causes such problems, I would contact the seller (store) and return the device.

Please report your results.

best regards

• 4. Shut down the computer. 
• 5. Disconnect the charger.
• 6. Remove the battery. (only for removable battery)
• 7. Hold down the power button for 1 minute.

Hello,

I completed all the steps, except for removing the battery as it is not removable.

The ACPI device returns upon restart. Issue still persists.

thx

Hello Spittdogg,

this could be an electrical interference, which is caused in the motherboard by the charging process and possibly also affects other components (also loudspeakers, whether switched on or not and internal components).

>I just bought the computer brand new last week

If the device is new and causes such problems, I would contact the seller (store) and return the device.

You cannot work well with the device in this condition.

Please report your results.

@Ub6424 - I purchased from Costco and there are no more units available for exchange, so return for refund is my only option. Will return if need be, but holding out hope I won't have to. I have 90 days to return, so have time to determine for sure. thx

Hello Spittdogg,

take your time and look at another notebook of equal value that meets your requirements. If you can return the notebook, that's fine.

So it's time to close the thread, please mark 'Accept as Solution' and we are done.
