Your RAM is either bad or not seated properly. One RAM stick is in the bottom of the laptop (underneath the windows sticker); this one is accessible by removing one screw. The other is underneath the keyboard. To get to it, you have to pry the thin panel near the top of the keyboard with the buttons on it off. Do this with a thin screwdriver on the right side (you will see a tiny indentation in the surrounding plastic) and pry it up on that end. Use your hands to remove it the rest of the way to the left. Then unscrew the 3 screws holding the keyboard down at the top and pull the keyboard toward the monitor and up. It should come mostly free, but don't do this too hard such that the keyboard cable becomes unseated. You will be able to see the RAM chip near the touchpad.

You should make sure both RAM chips are well seated. If they are, take one out and start the computer. If the problem persists, withdraw power and change which RAM stick is in. If the problem still persists, you either have two bad sticks, two bad RAM slots, or other problems (like motherboard) developing.

Latitude D630 screen is black from the time it is turned on. Computer is running, and I can see a little but it is mainly dark.


One of two components need to be replaced. The inverter board or the back light. The inverter is usually what will die. The inverter board is along the bottom of the display.

What are the 3 padloock lights for on the dell latitude d630


Look closely at the lights. Think "Number Lock" and "Caps Lock." Play around with those two buttons while looking at the lights. Then you will know what they are.

Please post back if it helps!

Power light comes on - numbers lock is lit steady, caps lock and scroll (I think that's what it is) flash. Screen stays black and then the laptop turns off...??


Can be one of three things:

Power not adequate enough for laptop - You can purchase a new power adapter relatively cheap from eBay for around $10.00. It may have been surged and will not allow the battery to charge or allow enough power to start the computer.

Bad battery - Take the battery out of the laptop and try it without. if it works, replace the battery or use without it.

Bad screen (inverter) - The inverter can be damaged. This can be caused by wear and tear, being dropped or other. The inverter is like a lamp that sits behind the screen. Take a flash light and place it directly into the screen to see if there is indeed a picture back there (will be very dim). If so, replace the inverter (difficult) or replace the screen (simple). Easier diagnosis would be to connect another monitor and see if it comes on (instead of the flashlight method).

Attach an external monitor. Does the external come on? May have to use the FN key + F8 to toggle it between the LCD and the attached monitor.

When you say that the laptop LCD glows a little bit, this makes me think the back light of the LCD has gone bad. If it displays fine on the external, then it is a pretty good chance the LCD back light has failed. If you can attach an external monitor and see something on it, run the built hardware test. This is done from a powered down state. Then press the FN key + Power, this places it into the diagnostic. Follow the on screen instructions. If it comes back with an error code, write this down and compare it to this list at Dell website. http://support.dell.com/support/topics/global.aspx/support/dsn/document?c=us&l=en&s=gen&docid=14B3819735D6B40EE0401E0A55177ED2

Occasionally, reseating the LCD video cable to the mother board will have a positive effect. Here is a link to the online service manual that explains how to reset it. In the diagram it is labeled #5 It is located under the keyboard.

Only caps lock just blinking on my dell latitude d630


Try reseating the RAM modules. They should be inserted at a 30 degree angle till the gold contact are completely in the slot, then pressed down till they latch in place, then just the edge of the contacts should be visible.
