    I have a Sager NP8170 for about a year now and I noticed that for some reason it makes a very, very light beeping noise...Its not 100% noticeable but if its very quiet you can hear it...I dont know what part of the laptop is making the noise but is this something that can be fixed? It goes away in and out non stop but its very light but still annoying.

    I just figured out its most likely the battery making the noise...When I plug the charger in the noise stops, when I take it out it continues...

    Can you be a bit more descriptive about "very light beeping noise". Does it sound like someone is punching buttons on a microwave oven? Is it high pitch squelling. Is it random or repetitive? Is it independent of processor activity?

    Could be HDD head load/unload cycling. This might be remediated by disabling APM and AAM everytime to boot/wake-up your PC.

    Or it could be noise from laptop power supply (cheap buck converters, capacitors, coils, etc...). Luckily, Apple fans have their hearing intact and were driven nuts by this a few years ago. The issue seems to have caused enough of a lash back in Apple's fan base for Apple to ponder whether laptops perhaps should not be making irritating squealing noises... Not so luckily for non-apple users, Apple has now patented the silent coil!

    Hopefully, the PC industry will eventually source parts from manufacturers that license this technology or better, one-them-up, so we'll one day be relieved of this non-sense.

    I had this happening on my old NP8170 and it was the hard drive starting to go bad. Could also be acoustic management as speculated on above.
