So here's where I'm at now so everyone understands. (I apologise if I had somewhat confused the issue within my posts).
I've upgraded from Windows 7 to Windows 10 twice. The reason for this is because when I did it the first time, I did not have a laptop dimming problem first of all. Then all of a sudden every time I booted up my laptop, it would dim to a point where I could not see it properly no matter what I did and by that I mean I tried everything!
So.... I then went back to Windows 7 and then upgraded to Windows 10 again. More time wasted! Once I was back with Windows 10 again, the problem appeared to not be there anymore until.... I clicked on "Display" in the Windows 10 Settings. As soon as I moved the slider for "Change the size of text, apps, and other items" & the "Adjust brightness level," then the dimming problem came back again.
So after conversing for some time with the laptop PC manufacturer and trying many remote online tests that still did not yield a fix for my dimming laptop, I've decided to do what the manufacturer has advised.
So I am upgraded to Windows 10 from Windows 7 at the moment and what they proposed that I should do is the following that will definitely fix the dimming laptop problem:
"You can do a clean install of Windows 10 using a USB stick that will need to be 4GB or larger,"
https://www.microsoft.com/en-gb/software-download/windows10
Simply download the tool and run it, following the wizard through to create your USB, then please back up any and all of your necessary data, as this will be removed during the installation process,
To perform a complete clean install, you will need to insert your Windows USB into the system and shut the machine down, then you will need to boot the machine and tap F7 repeatedly to bring up a boot menu, from the boot menu please select your USB drive and hit return,
Once you have loaded to the USB you will need to select the correct languages (please ensure the date & time and the keyboard input method are set to English (United Kingdom) Then click next and install,
You will need to accept the terms and conditions then you will need to select a custom installation, please then delete all of the partitions in front of you and install on your preferred drive, once you have installed you will need to install all of your drivers again, I would recommend downloading these from the downloads section of your account prior to installation, as you will likely not have an internet connection once the installation is complete prior to installing your drivers,
Please be aware that by doing this you will lose all of your data, so please be sure to back up prior to attempting this,"
This should then leave me with a brand new, clean install of Windows 10. Does that all makes sense now?
That's where I want to get to eventually. At the moment, I'm getting by with this Windows 10 upgrade and putting up with the problem of the dimming laptop.
Thanks
