XPS 8700, sluggish after update to A12 BIOS

I've read through the similar thread from a few weeks ago but none of the suggestions have borne any fruit.

Last week my 8700 "suffered" a critical BIOS update and it's now pretty much unusable for my normal tasks....namely photo editing.  DXO Photolab, Adobe Lightroom and Photodex software all respond slowly to many commands......things that I perceived as instant until the update can now take several seconds.  Performance monitor shows the processor running 100% @3.59Ghz whenever an adjustment is made but typically idles at 6-7% prior to any command. Boot from power on is also noticeably slower although I'm not particularly bothered by this

I've run the diagnostics at the BIOS boot stage and also reinstalled the Dell Support assistant but no errors are found.

I don't have the option of raising a support ticket as I live in France and the support site automatically switches to the French site in French language without the option of communicating in English.

The operating system is Win 10 Home Premium 64 Bit Version 1803

Is there a kind soul out there who'll give me a clue what to try. 

In desperation and anticipation....

Bob

Have you read this long thread on this exact topic?

Re: XPS 8700 sluggish after update to A12 BIOS

Thanks Ron but yes, I've worked through that and the suggestions but to no avail.

 

I've just discovered that Task Manager is showing that "Logical Processors" =1 whereas there should be 8.  When I run the diagnostics during boot up it shows and tests all 8 processors.

It gives me a clue as to where the issue lies.

You did not specify what you actually did?

(1)
Uninstall both the Dell SupportAssist software Dell SupportAssist Agent software. If need be, they can reinstalled at a later date.
* Right-click the Start menu button and select Control Panel
* Under Programs, select Uninstall a program
* In the list of programs, locate and select Dell SupportAssist
* At the top of the window, select Uninstall
* When done, locate and select Dell SupportAssist Agent
* At the top of the window, select Uninstall
* When done, restart the PC
* Test the PC for boot time and performance speed

(2)
User mvsoske disabled their Acronis backup software "Acronis Active Protection Service" which fixed their issue. So if you have similar software, check its active services.
* If still slow, open the System Configuration Desktop app
* Click the Services tab
* Check, "Hide all Microsoft services"
* Click the button Disable all
* Click Apply
* Click OK
* Restart the PC
* Test the PC for boot time and performance speed

* Open the System Configuration Desktop app
* Click the Services tab
* Add a check to one item
* Click Apply
* Click OK
* Restart the PC
* Test the PC for boot time and performance speed

Do this for every service under the Services tab until you find the service that is causing the slow down.

Re: XPS 8700 sluggish after update to A12 BIOS

Thanks Chris.  I'd previously tried option 1 (from the ealier thread) but nothing changed.  I've now tried option 2 (although I don't have Acronis)......still no change.

 

A couple of possible clues;

If I select the CPU performance monitor graph in "Task Manager" and right click to see all logical processors, it's greyed out.

 

If I look in the System Config, Boot, Advanced Options, the "Number of Processors" tab is ticked but the only option in the drop down box is 1

 

Cheers

Re: XPS 8700 sluggish after update to A12 BIOS

In addition to what @DELL-Chris M suggested, have you looked at the Advanced Processor Configuration settings in BIOS setup since updating to A12?

Are these settings Enabled or Disabled?

  • Hyperthreading
  • SpeedStep
  • Limit CPUID Value
  • Multi Core Support
  • Turbo Boost

My reading of the details about these settings in the Service Manual suggests you want all of them enabled.

Re: XPS 8700 sluggish after update to A12 BIOS

Hi Ron,

Thanks for popping in.....

They were all enabled except Limit CPUID Value.  I enabled it but Windows wouldn't boot at all afterwards and it went into "Automatic Repair" which looks like a Dell utility from the font......still running.   It's midnight here so I need to fall off the forum and get some sleep......back tomorrow.

 

Thanks again guys....

Re: XPS 8700 sluggish after update to A12 BIOS

Chris,

 

Sorry but I saw this message after I'd been advised to do a clean install of Windows.   As per my previous post, it was only showing 1 logical processor running at 100%.  I've now done a clean install of Win 10 (I couldn't afford to any get further behind with my editing work) and previous performance levels are back.  It runs around 20-25% (processor perf') and shows 8 logical processors when running the tasks that I mentioned in the opening post.

I've still a bunch of s/w to download but the critical ones are functional again.

 

Make of it what you will but I see it that the BIOS update did something to Win 10....you knowledge is undoubtably far deeper and I'd still like to hear your hypothesis.

Thanks for your suggestions and interest in my troubles....

Bob (productive once more)
