What do you mean exactly?

To increase or decrease the backlight brightness use Fn-key(next to left Ctrl-key) with up and down arrows.

There is not some key-combination to turn off the screen, you can make your computer turn it off after some time (if you're using XP this can be done in control panel->Power options), or just close the lid :)

I can't turn start the computer the screen is just black


Has the computer been dropped, jarred, etc. Are you getting a "ghost image" on the screen in a bright light? With little info, it could be backlighting, lose connection, monitor, ribbon cable, etc.

Where can i find the process to change a D410 inverter


If the screen on your laptop is dimming or not working at all, the fault may lie in the Dell Latitude D410 Inverter --the device that powers the screen's backlight. Replacing an Dell Latitude D410 LCD inverter will require some finesse, but you do not need a technical background. If you are comfortable with opening up your laptop, then this is a do-it-yourself project.
1. Unplug your laptop and remove the battery pack.
2. Locate the rubber screw covers around your laptop screen. There are typically four, but some models may have more.
3. Remove the screw covers. Take care not to lose any. They pop off and, if you are not careful, could go flying.
4. Place your fingers between the front bezel (the plastic piece around the LCD screen) and the screen. Gently work your way around the screen to remove the front bezel and expose the screen assembly.
5. Remove the inverter from the screen assembly. It is held on by tape in most models. In some models the Dell Latitude D410 Inverter may be right at the bottom of the screen assembly, below the actual LCD. Other models have the Dell Latitude D410 LCD inverter behind the screen. To disassemble the screen, you will need to either unscrew the screen from its metal holder, or just lift the screen out to expose the inverter.
6. Disconnect the wires leading from the Dell Latitude D410 Inverter. One wire goes to the backlight, while the other goes to the video card.
7. Look on the back of the Dell Latitude D410 LCD inverter for a model number or serial number. Having this exact number will make it easier to order a replacement.
8. Connect the video wire and the backlight wire into the new inverter and affix it using the tape that held the original in place. If you do not have that tape anymore, or it has lost its adhesiveness, you can buy more from computer parts retailers.
9. Put the screen back in place if you need to, and snap the front bezel back on.
10. Screw the front bezel screws back in, and place the screw covers back in place.

I have an older Dell Latitude PPX CPi that has nothing but lines on the screen. I hooked up an external monitor and it works fine. Swapped out LCD assembly with another PPX that I know had a good display...


The inverter is probably the most common failure on most laptop models and if you changed the LCD and the lines didn't go away, the inverter is the only thing that can cause them.

The backlight won't turn on but occasionally will flicker.


Suggest you replace the Inverter. A Backlight goes out all at once.
90% of the time the Inverter is the hardware part at fault.

[ An LCD screen cannot produce enough light by itself.
A Backlight is used to supply the needed extra lighting.
A Backlight is a CCFL.
Cold Cathode Fluorescent Lamp.
Similar to Fluorescent lighting used in homes, and businesses, but on a much smaller scale

An Inverter is used to required power for the LCD screen, and the Backlight.
Boosts power up for the LCD screen, brings it down for the Backlight.

Dell Support > Latitude D600 Notebook PC > Service Manual

http://support.dell.com/support/edocs/systems/latd600/en/sm/index.htm

Replacing an Inverter is a simple job. Replacing a Backlight is not.
The Backlight is located within the LCD screen assembly.

The metal frame of the LCD screen assembly is removed along the edge where the Backlight is located, to access replacing the Backlight.

In the above list for Service Manual, click on > Display Assembly and Display Latch.

This information shows you where the Inverter is located on a Dell Latitude D620 Notebook PC.
The Latitude D620 is part of the Latitude D600 series of Notebook PC's.

http://www.insidemylaptop.com/remove-replace-lcd-screen-dell-latitude-d620-laptop/

Just one place from a quick search, that sells Inverters for a Latitude D600 series Notebook PC,

http://www.parts-people.com/index.php?action=item&id=2895

MATCH the part number listed that they have, to the part number on your Inverter.
You have to have THE correct Inverter.

Need to delete bios password on a dell latitude cpi r400gt


I have just done this. One needs to dismantle the laptop first. Solder a push button switch with extended wires across pins 4&5 of the serial eeprom 24c02. Then reconnect the screen, keyboard & a/c power pack. with a tooth pick press power on switch whilst holding push button on. When the factory mode screen comes on release the push button. Next go to bios setup F2 and ALT-p to the password page. Now enter your new password this will overwrite the old pass word. My approach is slightly different to this following method as it is les likely to brick the laptop.

The back lighting for the LCD panel has gone out. The picture is there, you just can't see it without the backlighting. So, it could be the Inverter that supplies power to the back lights or it could be the CCFT lamps that burned out. In either case your local computer repair shop should be able to fix it. If it is still under warranty take it back to where you bought it and they should have it repaired under warranty.
