If your laptop’s LCD screen is dim, you’re not out of luck. When your computer monitor is dim on your laptop, you can still see Windows and your desktop icons, but the view is very dark and hardly legible. If your laptop boots up and the picture is dim, there are 3 ways to troubleshoot this issue:
- Hit the FN key and arrow up key. You might have lucked out and your computer screen went dim by the dim key.
- Hook up your laptop to an external monitor and press FN and the monitor F key (usually F8). This will let you know if you have a screen or video problem. If you see a good picture on an external monitor, then your LCD screen is the issue. And you may work like this as a cost effective measure.
- If you can see your computer picture on an external monitor, then you’ll need to replace one of 2 computer parts: the inverter board or the LCD screen itself. The inverter board controls the brightness of the screen while the LCD screen itself could have a bad bulb that is causing the dim view.
To determine if your computer needs a replacement interter board or LCD screen, you should see your nearest computer repair shop.
