    Hello Dalchina - you and I worked on this months ago and I think that is when I turned off Windows notifications and it stopped for a while.

    Thanks for your suggestion on Chrome - this was one of the many things I tried - I exited the Chrome agent from systray and still had the problem. I even uninstalled Chrome and it still happened so I installed a fresh version of Chrome and keep it updated.

    I also updated as many driver updates as I could find at Sony support as well. This is an older VAIO so not many new driver updates available for Win 10 specifically.

    The fact the 'problem' is well behaved is of note. It only starts when the laptop is idle for some period and stops when touching keyboard or mouse pad so it is 'behaving normally' for Windows which makes it harder to troubleshoot.

    JDF135 and others - this site has several posts offering different solutions. Some or one of these may work for you or others. I am going to disable 'Crashplan' per one post - this is one I have not tried. So weird that different solutions work for different people - including me (re: turning off Windows notifications months ago). Copy and paste the link below and read the posts for possible solutions.

    Win 10 Anniversary Update (AU) did the trick!! RESOLVED

    Yes, it appears that the Win 10 Anniversary Update (AU) resolved the pain in the butt problem many of us have had for months!

    I did the update today and so far the symptoms of high CPU and/or high disk usage has not occurred once.

    I let it sit idle for over an hour and other than normal blips on the hard drive there was nothing irregular happening.

    TIP: to get that AU update go to Settings>Updates> Learn More - this will open your browser on a Microsoft page where you can click to Get Anniversary Update started!!

    Another tip - Don't Minimize the update page after it starts. I did that on one PC and it never completed. I had to reboot and start over - thankfully it picked up where it had left off (no error message by the way) and completed without a problem. So on other PC and laptop I did not minimize that page and both completed without incident.

    So glad to see the disk light dark except for the rhythmic blip that is normal. Go for it - good days ahead!

    We did the following:
    1. Run intensive diagnostic for the disk on BIOS > Result: all pass meaning nothing wrong the physical disk
    2. We did turn off the Windows notification > Still has 100% spike on the disk

    Eventually, we end up update all firmware updates on all components (BIOS, network, disk etc etc) and end up the Disk Utilisation went to around 5% . In our case, before the Windows 10 upgrade, there is no firmware updates. BUT now we found that there is a firmware updates for this.

    Hope this helps
