It could be the high-voltage inverter board, I case of a faulty backlight (one of the tube flickers) the board would protect itself by powering off. Try changing one of the CCFL tube.

be sure no power and all power source is unplug. remove and connect your LCD connector. if not try to change your memory RAM.

If the laptop keeps working, and you can use it on an external screen, then it is likely an hardware fault.

First perform a complete system recovery, like probably already instructed by the Dell support helpdesk. This will practically exclude the possibility of a driver or system problem.

If the problem is hardware , then you may have a faulty inverter board , a bad LCD display/LCD ribbon connection, or a faulty video adapter (integrated with motherboard).

If the problem is the inverter, then the screen will go dark, and the laptop will keep working on external display. This is probably your case.

If the problem is LCD display or ribbon cable, then the display will be blank with light on , and the laptop will keep working on external monitor.

Fault concerning video adapter usually cause the the system not to work at all, and it is uncommon under conditions described.

low your brightness and then check if it is working with that

If the above link doesn't work then you can copy it and paste it in internet explorer directly.

Hi!

You can check the brightness with AC in the BIOS and match it with running in battery or else, when you plug the ac adapter, the lcd goes dim, press and hold the FN buttong and tap the up arrow then reboot and try to see if it will still do it. But still the best way to do it is going to the BIOS by pressing F2 at the Dell logo startup.

Hope this helps!

Thanks,

What Operating System do you run? If it is Windows XP SP2 (Home Edition or professional), here are some things you can do to speed up your system. 1st you should remove all programs that are not required from the start menu. Start > Run > Msconfig > startup tab. Unselect all that are not necessary. Also Right click on my computer > properties > Advanced > Performance settings > Adjust for best performance. This should speed things up a little. I would recommend atleast 512 MB of memory to run Windows XP and its applications decently. You should consider an upgrade.
