The screen stays bright in the bios for hours, boot into Vista it is dim, brighten it and it stays bright for hours. What would be causing this?

i also have a sony vaio z series and i am having the same problem as dave whereas i can only have the brightness at maximum or minimum. i am thinking it is software or driver problems but then im sure more people would have had the same problem. I have spoken to online sony reps and they have no answer. I still have warranty but i am reluctant to use it as i dont want to wait ages to get my laptop back.

has anyone been able to fix this problem??

Dell Laptop – Lattitude 5500 – Dim Monitor Issue

The problem started after running enirely on battery for a few hours. Running on regular power not help, monitor still dim.. Appears this is big issue with dell computers. This is a company laptop I using thank goodness, I sending it back and gonna use my laptop for the few weeks left of work I have. If this is what happens with Dell laptops I be darned if I ever gonna purchase one. ( I have an ACER by the way)

I seem to have the same problem similar to most. LCD screen is very dim. I could only read the screen with the help of my drop light.
If I close the lid it turn bright again, i can watch video for 5 to 10 minutes or so before it turn dim .
The problem started the day I replaced my battery charger 3 prong socket that sparks.
Did I screw up the power supply and busted something inside? or its my inverter/backlight problem?
please help

Hi!
My labtop started flickering when I turn it on and the flickering has gotton worse. WHen I unplug the power supply the screen goes dim and you can’t see anything. What could be the problem?

My company had an auction to get rid of old used laptops. I picked up 3 Dell D800s 2 of which wouldn’t boot and 1 that was fine except it had a dim display (readable but certainly not bright enough to use – even though brightness is set to max). I was hoping to swap out one of the displays from the models that wouldn’t boot but both of them are dim as well so it can’t be the inverter or backlight… any thoughts?

Darren,
My Dell D800 is acting the same way….I’m wondering if one of Microsoft’s updates is responsible as I tried to install XP SP3 and had to reverse it due to other issues. I’ve replaced the inverter with no change. My power settings no longer contain an option for screen brightness. I don’t how how long thats been gone. I’m going to try reloading XP and see what that does for me.

I have a Hp Dv2000. The problem is weird every time I boot my laptop the screen is dim[I can see the Hp logo]. after hitting the Fn F4 a few times the screen comes back on OR if I close the lid and open again after 3 mins the screen is on. the laptop then works fine for 2.5 hrs or so. then suddenly the screen starts getting dim and the back light goes off.

The screen starts working again after a few hours of using the external monitor.

-happens on both power and battery.
-external monitor works fine.
-lid switch works fine[have tested by disconnecting it]
-have tested the ram

I don’t know if the problem is the invertors or some voltage problem on the mother board.

Please help.

Dave,

I have no idea what the problem is. My latop is not even 2 months old.

I guess your laptop is still under warranty? Do not repair it yourself, call the manufacturer.

Darren,

Does this point more towards an inverter or backlight?

I think you have a problem with the backlight lamp but I'm not sure 100%. I posted your question here: LCD screen recently went dark
