The adjustment no longer works. And the screen is blindingly bright giving me a supersized migraine.

 

Anybody know how to fix this please?

Not on the information you have given us.

 

Desktop or laptop ?  Make and model ?  Main component specs if it is self-built ?  Post back with this information

 

In the most general sense, if it is a desktop borrow another monitor, if it is a laptop connect it to an external monitor. This will at least tell you if it is a monitor/screen problem or a computer problem.

Visit your laptop manufacturer website and download the latest version of the graphic card driver for your laptop.

Sadly, no - I followed the recommended procedure and it didn't work but it was worth a try and simple enough for even me to be able to do it.

I'll see if I can figure out how to do that - I don't find those sites very useful they always want info I can't find but I'll give it a go.

Visit below website and execute below command from Command Prompt that is open as a administrator.

wmic CSPRODUCT get  /format:list

The Dell website asking for Service Tag above command will output the Service Tag.

For example my laptop service tag is MBSR000686764 the output of above command list it as IdentifyingNumber=MBSR000686764.

How to Locate Service Tag of Your Computer

 

THANKS that's very helpful I will go ahead and check with Dell.   Incidentally, I'm not sure if this is connected but it may be - about the same time I noticed the failure of the screen brightness procedure - I notice that the "sleep" choice is unavailable, I only have the choice to shut down the computer or not.   I'm not sure if these have technology in common or not and they could be connected or not. 

 

I input the information you specified and for the Identifying Number I got 5X26C12 which does not conform with your MBS....... number - not sure why.

Well that was quite easy to complete as you had it all set up thank you.   There was a notice that one driver was available (it did not say which one to my knowledge) and so I did download and install it.   That part is great.   The problem with the brightness level adjustment not working remains.   If go to the brightness adjustment it shows that it is set on the lowest level which would be on the dimmer side however in actuality I can't imagine it being much brighter.   And I am wondering if there is a damaged file program?   Because about the same time I noticed this it also is the case that there is no longer on option to "sleep" the system.   There are two choices: shut down or restart?

 

Anyway I did successfully download and install one driver which went off without a hitch so that part is all good.  Thank you very much for making it all go so smoothly and sharing your knowledge to my benefit.

I was looking at the Dell website and came upon two items listed below which might help me - what is your opinion?   I know just enough to get myself into more trouble so I ask your opinion.   If you think either of this will help do you have information on how to do these tests?   I went to the downloads website but it didn't say anything about files only drivers?   Your opinion appreciated.   It seems like the built in self test would be a logical next step ?

 

  1. Test the LCD in the System Setup (BIOS).
  2. Run the Laptop LCD Built-In Self Test (LCD BIST).

I did download one driver during the process you referred me to - I don't know what driver it was but it was named amifldrv64.sys

 

I don't know how to locate any of the other drivers for graphic card.

 

I did find the method to run the Self-Test and the Dell Diagnostics test as well - the Self-Test passed all areas (but I do not think it was for software or drivers) and I received lots of recommendations for what to do on my own to find any problems but they appear quite involved and I just now got thru with the tests which took well over an hour.  So I think I will leave it at that for the night but if you can tell me how to locate and download the graphic driver that would be great. Thanks very much.

Please download and install Speccy to provide us with information about your computer.  Clicking on this link will automatically initiate the download.

 

 

To keep a record of your system profile at any given time, you can publish to the Web using Speccy. Speccy uses Piriform's servers to publish the profile without any identifying information. Each profile is given a unique URL. For an example, see:

 

http://speccy.piriform.com/results/nGmV1yekiTFbWJJ1oggVwcV

 

The last part of each URL is randomized, so only people you provide with the URL will be able to find your profile.

 

Note: Each time you start Speccy, it will generate a new randomized URL. This is useful if you want to track your computer's information over time.

To publish a Speccy profile to the Web:

 


  •  

     


  • In Speccy, click File, and then click Publish Snapshot.

     

     


  • In the Publish Snapshot dialog box, click Yes to enable Speccy to proceed.

     

     


  • Speccy publishes the profile and displays a second Publish Snapshot. You can open the URL in your default browser, copy it to the clipboard, or close the dialog box.

     

     


  • In your next post right click inside the Reply to Topic box, then click on Paste.  This will load a link to the Speccy log.
