100% disk usage all the time!!

[SangM]

Hello everyone.

From the first day I bought this laptop (last Christmas), it shows 100% disk usage most of the time, and it makes the laptop extremely slow and can't do anything, even simple internet navigating.

I don't have any external programmes which may affect the performance. (not even skype)

At the task manager, even 0.1MB/s of a Service Host or any program (like System, Windows update, and so on)  can make the disk usage 100%.

I looked up the problem on the internet, but nothing was really helpful.

Please check this for me. Thanks!

And if I turn it on for long enough, it does not use any disk resource (every value is 0 MB/s), but still, disk usage is 99%. 

CRAZY!!

Hi,

I also have the same issue with my HP Pavilion 15-036tu.

I have also tried doing a chkdsk, but still no success.

Would appreciate if someone could help.

I have the same issue with the Hp I5 bs599sa.  It is contantly on 100% Disk usage, got it in December 2017 for my sons Xmas present and he can hardly use it.  Will never ever get a HP again and will never recommend one either, my cheaper Dell is much better.

I've uninstalled McAfee with made no difference, not much else to uninstall, Office 365?

Measure, measure, measure.

Open the Windows "Task Manager".

Switch to the "Performance" tab.

Near the bottom of the window, click "Resource Monitor".

You can "drill-down" on the "Disk" tab, to see which files are active, and the bytes read/written per second to each of the files.

What program is accessing each file?

Click on the column-heading to sort the rows in each table, i.e., "bytes read per second", to put the "most-busy" files to the top of the rows.

Hi,

Just shows:

System

HPSF.exe

dllhosts.exe

Activehelathanalyzer

svhost.exe

Then loads HP based ones.

I would have expected that it would give numbers for bytes-read-per-second, and bytes-written-per-second, and more, including which files were being accessed.

Do you mean 'HPSF' or 'HPSA' ("HP Support Assistant") ?

Do you mean 'Active hel ath analyzer' or 'Active Health Analyzer' ?

Do you mean 'svhost' or 'svchost' ?

What happens to the percentage after you select 'ActiveHealthAnalyzer', and right-mouse-click to "terminate that task"?

Same question after you terminate HPSA ?

Does it reduce significantly?

Sorry for the spelling mistakes I didn't have my glasses on and it was late.

I will try this later and get back to you.  Maybe with a screenshot or 2.

SOLVED!!!!

Uninstall HP CoolSense!!!

Disk usage immediately dropped from 100% constantly to 3%!!! I repeat...the culprit is HP CoolSense!!!!

All the other recommended measures are pointless...this is the FIX

Unfortunately, my laptop doesn't have HP CoolSense installed.

I hope some people may get helped by your solution 🙂
