Re: screen is dim

Try looking for a function key (usually used by holding down the Fn key and then pressing one of the "F" key at the top) the key will be marked with a brightness indicator.

Is your screen only dim when running off the battery is it dim when running when the charger is plugged in as well. If it is only dim when the laptop is running on battery then this may be caused by a setting in Power Options which is located in Control Panel (that is if your running Windows). In Power Options look for settings about running on AC Power and running on Battery power.

Screen is faulty. It divides in equal half and displays well on one side and dims on the other. I can read info on both sides but dim side displays faded colour. External monitor works fine.

Usually not. The circuitry that drives the panel is integrated with the screen.

It's some work but those screens are serviceable and you can often find a good replacement on eBay at a fraction of the cost of a new HP part. A local small computer shop could probably swap it out for you in less than an hour.

Good luck.

My hp coa-se laptop mdl 661631 fhe screen is so dim u cant see it... how do i fix it?

The image on your screen is made up of two parts the lcd screen that creates the image that you can see dimly and a backlight that shines trough the screen brightening it so you can easily read the screen. In your situation in would appear the backlight bulb is burnt out and needs to be replaced. If your handy this is something you could do yourself a search on google for "backlight" and your specific laptop model will bring up available replacement bulb and quite possible detailed instructions on how to replace

Screen flickers on Acer Aspire A150 Netbook


It really sounds like you have a short in the ac adapter. Laptops dim the backlight on the screen when on battery power and go full brightness when on AC. I think your adapter is going on and off. When it is on the screen is on full and when it goes off the screen dims down a bit. You could have a bad adapter, most likely, or a bad charging jack in your laptop. Check the adapter first, just use a multimeter set to voltage. Read lead goes to the center pin and black lead goes to the outside metal contact, you should get a reading of 18 to about 26 volts. Move the wire around near the plug that you are holding and keep checking the readout. I think you will find the voltage dropping as you move the wire.

I hope this helps, If so please rate my solution.

Dim display on Toshiba Satellite 4090XDVD notebook

The backlight CCFL lamp provides the lighting for the LCD screen. If you have already adjusted the brightness to the max. setting and it is still dim, it means the CCFL lamp is is nearly worn out. To determine if you have a LCD screen or video card problem, read this and follow the instructions. Defective CCFL backlight, it may have the following symptom: Screen flashs on red/pink and off. Picture stays on in red and slowly be come normal. Picture flickering with dim display or appear black. Picture flickering on and off. All these symptoms indicate that the LCD backlight lamp (CCFL Lamp) has reached the end of the life and all you need to do is replacing the CCFL lamp. Connect an external monitor to your laptop and power the monitor up first then the laptop, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight. Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case. The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills. Check out for parts, repair service and DIY info.

LCD goes dim within 1-2 minutes

You could have a bad "inverter" or flourescent backlight tube, or a problem in your power supply.The only way to isolate the problem is to check each component in sequence.If your hard disk and DVD / CD drive are still working when your screen goes dark, then I'd say it's the "inverter". You'll have to take it to a repair shop.
