Disable Brightness Change when charging Lenovo Ideapad
I have a Lenovo 320S-15IKB (Type 81BQ) Ideapad Laptop. This is a new laptop with latest versions of drivers and utilities installed.
When using the Intel Graphics app, I attach the charge cable, the Ideapad's screen gets brighter; when unplugged, it returns to the previous brightness level. I want the screen not to change brightness when I plug in or unplug. If I disable the Intel Graphics app, the Ideapad does not change brightness when the power state changes.
As you see in this screenshot, there's no option to change it in Windows Power Management software. There should be a pair of sliders for brightness as the third items, one under 'On battery' and another under 'Plugged in', but they're missing.

Display of the Brightness slider should be controlled by the Registry keyHKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlPowerPowerSettings7516b95f-f776-4464-8c53-06167f40cc99aded5e82-b909-4619-9949-f5d71dac0bcb value DWORD Attributes. Set it to 2 to display the slider. However, that might not display the slider in some circumstances.
You can set the brightness through the Registry directly to work around that issue.
- Press Win, type
regeand Enter to open Regedit. - Copy the key
HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlPowerPowerSettings7516b95f-f776-4464-8c53-06167f40cc99aded5e82-b909-4619-9949-f5d71dac0bcband paste it into the Regedit Search bar to go to that key. In the key
DefaultPowerSchemeValuesare sub-keys forACSettingIndexandDCSettingIndexto adjust the percentage brightnes on mains power and on battery power, respectively. Set them for each GUID, so that all plans have the same brightness setting on battery and on mains.N.B. If a third-party app such as the Toshiba eco utility controls screen brightness, you may need to search the Registry for
ACSettingIndexand change the values there, as well.
Please let me know if either Registry setting resolves the issue.

I have Intel Graphics as well on my 20FB-CT01WW Thinkpad X01 Carbon, and the slider is present. So, it's not Intel, but an installation glitch or a bug on Lenovo's side.

Actually, those should just be default settings. If you hibernate, the brightness should just return to the last (manual) setting on starting up again.
