Strange one this.  I can't tell if this is a Windows 10 or an Acer issue.

When on battery and the screen turns off, I can hear the hard drive constantly powering down and up.  It sounds like it's going through hell.  This doesn't happen when connected to the mains.

Check out video in the link.  You might have to turn the volume up.  You can hear the hard drive doing the thing I mention once the screen goes off.

I thought it might be the power settings.  So I went to advanced power settings and set "Turn off hard disk after 0 minutes (i.e. never)" on both battery and power but it didn't make a difference.

Thanks in advance.

    OK. Open Control Panel. Search power plan. Select change what the power buttons do in the left panel. Click change settins that are unavailable. Scroll down the list and uncheck fast startup to disable fast boot. Reboot machine. If that solves the problem, leave it in cold slow boot mode cuz it solves a lot of other problems that crop up from time to time. Jack E/NJ

    What do you mean by "when the screen goes off"? When you press the power button to turn it off? Or when it automatically turns off after idleness time period ? Jack E/NJ

    The latter.  When the screen turns off according to the power plan settings.  Happens only when on battery.

    The problem still sometimes happens when the laptop is going to sleep.  Any ideas for that?

    Yep. Seems reasonable. One or more of the apps, programs, processes, or websites you've been using and exiting just prior to putting it to sleep isn't releasing memory which in turn may continue to call on the CPU and drive. Usually due to sloppy coding. Open task manager just before you're ready to put it to sleep. Check which ones may still be consuming a lot of disk time. If you recognize them as something you've just used, right click and end the tasks. Jack E/NJ

    It feels like it's an OS setting or hardware issue.  It doesn't happen at all when the laptop is plugged in.

    One or more of the apps, programs or website that you're ***sometimes but maybe not all the time*** using, running, and visiting  are sloppily coded and leaving stuff in RAM that's still activating the CPU and/or drive. Sleep mode doesn't clear RAM.  Hibernation mode will almost like a cold slow boot. Then saves what's in RAM to the drive. So open Control Panel again. Search lid. Select change what closing the lid does.  Change from sleep to hibernate. Takes a bit longer to load from the drive when the lid is opened again. As for it not happening at all in sleep mode when plugged in, I think that's more of a coincidence of how you've been using the machine. It still doesn't sound like a hardware issue to me. Jack E/NJ

    It's most noticeable when the screen goes dark (Power Options -> Change plan settings -> Turn off the display) but also sometimes occurs when going to sleep.  But I've tested this several times and I can see that it never ever occurs when plugged in.  So there's definitely a link there.  If you have any ideas how to fix the issue further, I'd appreciate it.  Otherwise, thanks for your help.

    Never say never. :)

    If you've got the screen going dark after a certain amount of inactivity time, this ONLY affects the screen. This setting does NOT clear RAM or stop CPU or Drive activity. The drive, especially during times of inactivity, will automatically go into defrag mode to enhance drive read write performance. In the old days of Win98 and WinXP, defrag was always done manually. Now it's automatic.

    To clear RAM and stop CPU & Drive activity including auto defrag, the lid or power button settings should be changed from sleep to hibernate. The screen inactivity time settings have no affect on hibernation mode.

    Again, I don't feel there's a hardware problem here.  Thus I don't think anything needs to be "fixed" other than experimenting with the lid, button and power plan settings.

    I should probably qualify my posts a little, I'm a Software Developer and qualified Computer Engineer who has been using computers comfortably for over 20 years.  So I totally get the difference between screen off, sleep (low power mode, everything still in RAM), hibernate (effectively off but with contents of RAM written to hard drive for resumption later) and shut down.

    The info that defrag happens during inactivity was new information to me so thanks for that.

    As I say, the issue does happen only when on battery and every time the screen turns off according to the power options settings.  Did you watch my video in the top post?  The clicks I'm hearing do not sound like the kind of activity you would expect during a defrag.

    I tried to boot from Ubuntu from a flash drive to try and single out whether it was a Windows thing or a hardware issue but I've had separate issues related to some kind of hardware compatibility issue and the latest version of Ubuntu so far.

    I'm not unappreciative of your input.  I do appreciate it and the time you've spent greatly.  But I feel there's a misunderstanding with regards to what is happening.  I hope I've made it clear.

    >>>Did you watch my video in the top post?>>>

    Watch, yes. Hear, no. I usually can't hear anything above 1200Hz that's loud enough to override my tinnitus hiss even with earphones. An unpredicatably intermittent event like this is gonna be hard to pin down even with knowing it only happens unplugged with the screen turned off. The only thing I can suggest is to set all inactivity times to never shut the display off. Then change the power or sleep button settings to sleep or hibernations modes on battery alone to see if you can get it to click sometimes in each mode after pressing the power button to turn the screen off manually.   Jack E/NJ

    Ok.  Thanks.  I've actually set my laptop to never turn the screen off when on battery and just sleep after 10 minutes (it was still happening on screen off - though less frequently after I made the change you suggested).  Oh well.  Just one of those things I suppose.  Thanks again for your help.  I'll report back if I can ever get Ubuntu working from the flash drive.

    Just in case it's MBR partitioned, the live Ubuntu stick must be GPT partitioned or the UEFI bootstrapper won't see it. Also try all the USB ports to boot from it. Jack E/NJ

    By the way, just as a follow-up, I never did get rid of this problem and basically just used the workaround mentioned above.

    Eventually, I upgraded my primary hard drive to an M.2 SSD for separate reasons whilst keeping the mechanical drive in for storage.  This wouldn't have solved whatever the underlying issue was but it meant the mechanical drive stopped doing the clicking when screen went black.

    By the way, I can highly recommend upgrading to an SSD if you can.  Made a world of difference to the laptop's performance.  Especially on boot/login and but especially when the OS was reading/writing the pagefile so switching applications was so much faster!

    Thanks for the report. Yes, agreed, switching to an SSD perhaps yields the biggest performance bang for buck of just abojut any upgrade. Jack E/NJ
