Question Can't adjust brightness on windows 10 on my old notebook hardware upgrade

[TakedaYabu]

Hello everyone,

I have a 2010 Acer Aspire 5742ZG (p614g32mnkk) with original BIOS v1.01 running on Windows10 for 2 years now (original was Windows7 Home) and I have recently done the following hardware upgrades:

from (original specs)...

• HDD 320GB
• 4GB DDR3 1066Mhz
• Intel P6100 (2.00GHz - no turbo)

to (all specs are brand new)...

• 2.5" SSD 240GB
• 8GB DDR3 1066Mhz
• i5 540M (2.53GHz - 3.07Mhz)

The problem is that after doing all of these upgrades and reinstalling windows, I can no longer change the brightness on my screen like I always did... The workarround I found for this was to install and activate the BASIC WINDOWS GPU driver and then change the brightness to the level I want... How to fix this?

Hello

Can you please confirm if the Change brightness bar is enabled on the Display window?

Assuming it is disabled, I was wondering if you already tried the following:

* Go to Start >> Settings >> System.

* Click Detect or Identify (whichever helps) from the right section of the Display window.

* Select 1 monitor and see if the brightness bar is now enabled.

Hope this helps.

Cheers!!
