    Computer randomly sleeps, high cpu after 5 minutes idle


    Earlier today I was downloading files from my browser and my computer went to sleep halfway in. This random sleeping happens occasionally. The event viewer doesn't mention anything about overheating, it always says it's just idle (event 42):

    Sometimes it goes to sleep even while my mouse is moving, gives the same reason.

    Another issue is my cpu starts acting up after sitting 5 minutes idle, happens every single time.

    I made a thread about this a few months ago. I thought I found the answer but I didn't. Seems to be related to 'System and compressed memory'.

  2. Cpu Usage by LockAppHost.exe

    I'm seeing LockAppHost running high CPU for several minutes after wake-from-sleep. Surface Pro 3. On wake from sleep the computer is unusable for about 5 minutes. Argh!

  3. Apps Using More CPU Than Normal

    Twice a year there are some major updates that get sent out, and they can cause some significant CPU usage until the update finishes in the background. I usually suggest setting your power options to "do not sleep" and let the computer sit overnight.
    After it's all done, your idle CPU should be 2% or less and no background task workers hogging the system. Learn more about these here:

    It is normal for a system to hit high CPU use right after coming out of sleep state. Usually it is the malware software scanning the system.
