Hi, i have this old dell laptop that has been working without any problems. Yesterday after using it for about 10 min, the display just turned very dim, it was difficult to see. So i pressed fn+arrow up-down and the display did become brigther but after about 5 minutes it went back to dark dim. Do you have any suggestion? Could it be power issue(friends advice) Thank you soooooooo much!
Does sound like a power issue. Assuming it's windows xp, you can check to see if it is a poiwer management setting:
Go to start, settings, control panel, display, and on the 'screen saver' tab at the bottom should be the "monitor power" area, click "power".
There is a power schemes area there. Check out what your settings are. Laptops often have settings for when plugged in versus when unplugged; when troubleshooting this make sure you are positive about if you are 'plugged in' or not as it will affect settings! :)
(On Vista go to Control Panel, Power Options; same thing, change your settings there)

Hi there, if i read you correctly you are trying to connect external monitor on laptop. As you use old Monitor for this you can probably establish only VGA connection . For this you dont need any special drivers if you use VGA external connector on laptop. You just need to find out right combination on keyboard to activate external monitor to be activated or right click on desktop then properties and display option multiple displays. Of course when you manage to activate mode for external screen please use lower resolution like 1027*768 for second display aka monitor to test .Cheers
this is not a pc problem... this is because the connection loss between pc and monitor... not all pc's have sleep mode in externa vga connection.... it just cuts power off... u can configure monitor of possible to do that..
Try to connect the monitor to a working PC. If there is no problem, then you may try your laptop with a working monitor. If you having same problem may be you should review the process for outputting display from your laptop.
You may have a defective CCFL backlight, it may have the following symptom: Screen flashes on and off or displays reddish pink hue. Picture stays on in red and slowly be come normal. Picture flickering with dim display or appear black. Picture flickers 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 replace the CCFL lamp. To determine if the video card or the LCD is faulty, 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. It could be a faulty inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out; usually the CCFL lamp fails before the inverter. The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

I see many monitor with that trouble.
When you turn on comp., you can have a picture on monitor about 10-30 min. and that go in black screen, or If you change resolution again go in black screen.
You must repair monitor or bay another.
I think there is some severe problem in the VGA of the laptop, that is not supporting your LCD. There may be some thing relating to a very sensitive golden color strip in the laptop that is used to VGA signals. If you have opened the laptop for repairing then it can be a issue. Better to try another VGA first and then tell me what happened.
Not all laptops display adapters will allow the individual settings for a screen and a monitor to take effect correctly.
This happens especially when one is a widescreen and the other is a standard screen.
It seems your settings are taking effect on both screens at once instead of on each screen individually.
I assume you have adjusted te display sizes in your display settings ?
If so, did you adjust each display separately ?
You may also have to see if your display adapter has the most correct drivers. That may help.
Connecting an external monitor will not mess up the laptop.
Most laptops have a standard 15 pin VGA external monitor connector. You
need to connect the cable from the monitor to the laptop. Booth the
Dell and power up the monitor. Soon as the laptop has gone through its
routine of booting, press Fn + F8 or F4 (or whatever it is that needs to be pressed to activate the external monitor. It is normally an F key with the small monitor icon or the words CRT/LCD).
Pressing on the two (2) F keys would cycle on laptop display, laptop display + external, external only.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
This problem is most likely to be caused by a bent or broken pin on the CRT video cable at the VGA connector, OR, this could also be caused by a damaged VGA connector on the back of the laptop.
If neither VGA connector is at fault, the problem could be caused a damaged (kinked) CRT data cable, or internal damage to the VGA connector on the back of the laptop, though I suspect the problem is more likely to be external, and you probably won't have to disassemble the laptop to locate the culprit...
