Can anyone confirm that your battery life gets extended using this method of switching to integrated gpu? For my understanding when switched to integrated gpu dedicated is still using power even if I disabling it in Device Manager. After I switched to integrated gpu the battery indicator saying that I have 1h and 40 min of battery life on 100% charged battery which is same amount of battery life I had being on dedicated gpu. I went to Device Manager and disabled the dedicated gpu. But battery indicator still showing that I had about 1.5 hours battery life so then dedicated is still using power even if it is disabled. Also with integrated gpu I have an issue that I cant change the screen brightness. I tried different fixes: rollback intel driver uninstall intel driver disabling adaptive brightness in Power Advanced Settings disabling-enabling Generic PnP monitor disabling Service Monitoring service rebooting after each change Nothing helped. However when I switched back to dedicated gpu and restarted PC the screen brightness working the way it was working before but then when I switched back to integrated gpu still have such issue. Any thoughts?
