Hello!
So after finally (and I hope also permanently with BIOS update) solving the issues with sleep/hibernate not working and some drivers being jerks :), getting the laptop into what i call a working state, there is still one thing that bugs me and I need to help with.
Every time I start the laptop about 5 minutes after logging into windows, there is a high-pitched sqeaking noise that lasts about 1-2 minutes, than everything gets back to normal. It´s such a high frequency I bet many people would barely, if even notice it (already got a few people look at that personally and none of them could hear it). Thing is that during the noise, everything seems to be slowed down and stutter (for example if I´m watching a youtube video during this happening, it starts to tear really badly... if I´m launching a program, it takes longer than usual to start). Noise also changes according to what I´m doing, if I start a program it gets higher and louder, same when I´m moving opened windows or scrolling webpage.
It happens every time I start the laptop from cold boot or wake from sleep. Strangely, it doesn´t happen when I restart. It also happens only after logging to windows, if I idle on a log screen for whatever time, nothing strange happens.
Some other observations I made:
- in CPUID Hwmonitor, CPU wattage goes up of about 5 watts during the noise and then drops back to normal idle/whatever wattage, temperature stays normal all the time
- sound doesn´t appear when uninstalling Intel HD 4600 graphics driver to Basic Microsoft Display adapter, I tried using all versions of HD 4600 drivers, from manufacturer´s to latest generic beta, noise appears on all of them
- also, I´ve had some problems with buzzing earlier, which I suspect was an ethernet card, because it used to stop when I plugged in a cable and after using different drivers, the buzzing completely stopped and I could relatively precisely locate it from around LAN port just by hearing. I wonder if this might be somehow linked.
- I´m sure none of the programs not-preinstalled is causing this, since I already did a factory reset while solving sleep issues and this noise came back right after recovery (was happening before too)
Specs: i5 4200H w/ Intel HD4600, 8GB RAM, Nvidia Geforce GTX 950m 2GB DDR3, Windows 10 Home x64 (GL552JX-DM021T)
After all problems I´ve had so far (and other read about on this forum) this is the one I can easily get to live with, since it happens only for a short time, but I´m really reliant on a laptop not failing on me (warranty or not, I own it for about a month and a half), so an advice if I should be concerned about this would be higly appreciated.
Thanks,
Ghostly
