Disk Usage Locked at 100

Hey friends

For the last few weeks, my laptop has been slow and unresponsive much of the time and is locked at 100% disk usage, even when nothing is open or running in the background. It's Dell Laptop with an i5 and 8GB of RAM, and everything else appears to be running normally, i.e. the CPU/GPU/etc are not locked at 100% or anything.

As this is a fairly common problem, I've tried the usual solutons; disabling superfetch etc has done nothing, I've done a scan for malware etc but have turned up nothing. There are no programs in the task manager that claim to be using the disk, and using the usage monitor tab shows that the programs using the disk are not consistent.

The strange thing is that my computer runs fine on startup (beyond the usual first few minutes of lag), and only locks at 100% after it's been closed/slept. In order to use my laptop I have to restart it every time I use it, and that's extremely frustrating.

I've attached two screenshots of my disk usage taken like 30 seconds apart: https://imgur.com/a/DfNldde

As you can see it's a mishmash of windows services, random programs, etc, none of which are apparently running. I'm at a loss. Anyone have any advice? Thanks!

Interesting.

Looked for some background information and found the following link:

My thought is that some power related issue with respect to "primarily AC" that may not allow the disk drive to operate normally when first plugged in.

Unplugging cleared the "bottleneck" so to speak. So when you changed to "standard" the matter became moot.

In the link, bottom right, try the Troubleshooting menu and use the procedure provided to look at the relevant Event Viewer logs.

Compare log entries using both settings.

You might find some specific error or event that can be fixed and allow you to...
Consider a failing disk drive.

Back up your data and then run the applicable disk diagnostic software from the disk drive's manufacturer.

Remember that anything you do may cause further damage and loss of data....

Also try the Reliability Monitor - it may provide some additional insight (beyond Resource Monitor) that will help identify the problem.

Type "View Reliability History" into the "Type here to search" box.

Go back through the history and check the red circles and yellow triangles. Read details when available.
 


I considered the drive could be failing and all my important information is backed up, but I'm not sure how that could be the case. Right now, for instance, my disk is functioning normally, and if it were a hardware problem, wouldn't it be a persistent 100% lock? I guess anything is possible but it seems unlikely.

One thing I hadn't considered: a little while ago I'd had some problems with my charger, and in the process of fixing that I altered a few power settings in BIOS, which I didn't think would affect anything else. It occurs right now that I'm using my laptop not connected to AC power for the first time in a while (I know, I know; bad laptop parent,etc) and it's working perfectly fine. Is there anything you know of in the power settings that could possibly cause the disk to lock up when connected to AC? Seems bizarre to me. I won't have access to my cord until later tonight and I'll investigate then.
 
Inconsistent, intermittent problems can be quite quirky....

Perhaps the battery cannot consistently handle the load.

Or vice versa, something astray when using AC.

Key is to find some pattern where you can produce or create the "locks" at will.

Change only one thing at a time and keep notes. Could be some combination of events: the proverbial "perfect storm".
 


I can now confirm that plugging my laptop in causes the disk to lock at 100, and unplugging it immediately resolves the problem. So. Confused.
 


Don't want to speak too soon, but I appear to have solved the problem by changing the setting in my Dell Power Manager from "primarily AC" to "standard". I cannot for the life of me understand what the underlying issue causing that to happen was haha but thanks for all your help.
