Hello, I have a laptop Dell Inspiron n5110. I recently reinstalled the Windows, but i noticed something. After i installed all the necesarry drivers and rebooted it for the first time after it, i tried to adjust my screen brightness from the power options menu. I noticed that no matter on what level i put up the brightness, It didn't change for the first 30 seconds.Do you think this is from the reboot, since it is just after install and it needs time to adjust some settings, or there is problem with the laptop? It only happened on the first reboot after I installed the drivers, after it whenever i change the brightness level from the menu, it also changes immediately. I also have to mention that i dropped the laptop a few days ago. I hope for your advice because i am really worried.
