Question

Continuous Beeping From Laptop

Sep 8, 2017 6:40AM PDT

I am running a Samsung Notebook 9(one from 2015) with Win10.

Only today, I have noticed a continuous high-pitched beeping coming from somewhere around the touchpad. It isn't a steady stream, but it goes beep-beep-beep really fast randomly.

The weirder thing is that the beepings stop when I touch the touchpad or move the mouse. At first, I thought it could be a bad CMOS battery, but I ruled that out. After running various tests, I confirmed it wasn't a stuck key either. So my other options are a bad motherboard or shorted PS/2 port.

I would also like to add that the laptop works absolutely fine. No RAM errors, no errors, no faulty drivers, and system files are not corrupted. No hot temperatures either. It's running at 29 degrees Celsius with only Chrome open, which is normal.

Would anyone suggest a fix or any other ideas as to why the beeping happens?

Thanks.

Try going to the BIOS screen.

Why? To see if it stops. This varies with the machine so check your product manual. Why we want to do this is to see if the machine noise stops when there is no OS running but powered up.

The usual find is a HDD that's making noise. We might run a HDD test (again, the maker tells how) and consider replacement depending on the results.

Thanks for the suggestion. I'll try it soon. It definitely isn't an HDD making noise, because I have a Solid State Drive. Better try the BIOS Screen.

Nope. I don't hear any sound on the BIOS Screen, from what I can tell. As soon as it powers up and enters the Windows Desktop, it starts making the noise. It definitely isn't the speakers, because I have an earphone plugged in and my speakers are muted. The touchpad drivers are up-to-date, the PS/2 connection was diagnosed to be fine according to the Windows Device Manager, so I don't know what could be the cause. Now I'm wondering if it could be a piece of dirt or dust that is somehow magically triggering a keyboard input. Or maybe a bad/shorted circuit somewhere else on the mobo.

I was running more than 4 tabs while running that test, and I happen to know that every chrome tab is a sperate exe instance, so I think it is legit.

OK then ... does the beeping occur in Safe Mode?

Nothing stands out there.
Sep 9, 2017 6:40AM PDT

I was looking to see if anything stood out or a high temp but outside a few too many apps, it's pretty clean. I didn't look to see if there was spyware or what signkorea was.

I think you'll have to ask Samsung what next. They will likely factory reset the machine so backups are your choice.

Most BIOS screens don't use the trackpad/mouse. Windows always does. How about trying a live Linux distro, either off a CD if you have one or a USB stick. They also use the trackpad/mouse, if the noise goes away, it's likely a Windows software/driver error or a Trackpad/mouse setting, Windows has a lot for some systems, though you'd expect it to be consistent in that case.
