USE:the BIOS must be fully updated BEFORE the computer is restarted; Do not interrupt the update.

BIOS updates are not as frequent, so you don't have to constantly update your laptop's BIOS like your generic drivers do.

Replace the LCD inverter

If the above tips didn't improve the brightness of your screen, chances are your laptop's LCD inverter is defective or has failed. This little piece of hardware is responsible for the screen's backlighting (i.e. what makes the screen glow).

The LCD inverter, like any hardware in your computer, can fail for unknown reasons. It is best to take your laptop to a professional to have the LCD inverter replaced.

Don't try to find it yourself, as you could void your laptop's warranty by opening the case. It's probably hidden under other hardware, and you risk permanent damage to your laptop if you try to remove it yourself.

We recommend taking your laptop to a professional if your screen is still dark after trying these fixes. They can pinpoint the exact cause of the problem and give you a better idea of ​​what the possible solutions are.
