Remove all attached devices like printers or flash drives. remove battery and power on using ac adapter only. if it still wont work, try another good ac adapter. make sure ac adapter light is on. if it still shows the power light on and nothing else, replace motherboard.

D620 display issue


Maybe your problem was not the lcd screen. Before you replaced the lcd screen you should have tried an external monitor to see if it would work. That would help isolate the problem which might be the Video Card.

If I'm not mistaking, the D620 has the Nvidia Video Card that was a major manufacturing defect. In fact my daughter had one and I had to reflow the video card because it was bad.

Count the Beeps and notice the pattern of the beeps ( 1 Long or 1 Long followed by 2 Short). They tell the technician what is going on with the computer. I'm betting you have a Video Card Problem.

When i switched on my dell laptop (latitude E5500) today, it just displayed a black screen . the tiny power lights on the keyboard are blue which means the laptop is working fine ,just the screen goes...


hold the Fn Key while powering on, this will enable the PSA diagnostics, if you get any video and or the diags function then that should give you an indication of the problem.
If you only get LED lock light indications, then check here:

I went out leaving my dell latitude D620 laptop on for hours, when i got back the screen was blank. i powered on and the lights came on and went off again


1. Check and see if the LED is on with the AC adapter, if possible, try a different Dell AC adapter (ANy D or E series Dell with a cannon plug connection should run that system Also ensure that the adapter is plugged into the wall.
2. If a known good power adapter does the same thing or if the LED goes out as soon as the adapter is plugged in to the system then the motherboard is suspect

Dell lattitude d620 won't factory restore ?


Hi,


Please go through the below step, you can able to do it.


1) Shut down the Dell Latitude D620 if it's currently powered on. Click "Start" in the left-hand corner of the screen to access Windows' shut down options. Alternatively, press and hold the Latitude's power button, located on the top edge of the laptop's keyboard.


2) Turn on the computer by pressing the laptop's power button.


3) Press and hold "F8" on the top of the laptop's keyboard immediately after turning the computer on. If the Windows logo appears on the screen, you're too late and must repeat Steps 1 through 3 again. If you pressed it in time, a list of text options will appear on the screen.


4) Use your keyboard's arrow keys to scroll down to "Repair Your Computer." Push the "Enter" key on your keyboard.


5) Choose a language from the next list and select "Next." If you've password-protected your laptop, you will be prompted to enter your user name and password at this time.


6) Press "Dell Factory Image Restore." A new window will appear. Click "Next" and select the option for reformatting the hard drive and restoring the factory condition of the laptop.

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.

Dell latitude d620 once i turn on power the power and bluetooth light comes on while the keyboard status lights flash screen stays blank and after about five seconds turns itself off ?


Is the laptop really turning itself off, or is the display just not doing anything?

It sounds like it could be a problem with the nVidia GPU used on the D620.

Dell has extended the warranty on the nVidia GPUs by 1 year. Call Dell and describe the problem.

Dell Latitude D620, Black Screen/Power On


It is the backlight! That laptop uses a fluorescent lamp. It is bad.
If you look carefully at the screen, you will see the Windows desktop (or whatebver you are running). It just needs to be lit up.... from the back. Tel them to replace the LCd screen or replace the lamp.

Hope this helps!

Dell Latitude D620 - Screen shows boot up, but then goes blank. I know the screen is ok as the dell part shows on screen, but when the blue screen should appear to insert password etc, the screen remains...


Here are some easy things that can sometimes resolve this problem:
1) Sometimes there can be a static buildup on the mother board. Power off, remove the battery, remove the power cord and hold the power button in the on position for at least 30 seconds.
2) If that didn't work- Power down, remove the battery, remove the Hard Drive and memory modules and reinsert them. Try to power back up
If these things don't work, get back to me for some more ideas.
Hope this helps and have a super day!
