How do i brighten my ac er laptop?

To brighten your Acer laptop screen, you can usually adjust the brightness using the function keys on your keyboard. Look for the keys with a sun icon, typically found on the F keys (like F1, F2). You can also adjust the brightness through Windows settings by right-clicking on the desktop, selecting "Display settings," and using the brightness slider. If you're using Windows 10 or later, you can also find brightness settings in the Action Center by clicking the notification icon in the taskbar.
