Having problems with your Dell Latitude D620 Notebook ?

Dell D620 Won't POST

\015 Hello,\015\012I was using my Dell D620 until this afternoon, when I ran into what looks to be a serious problem. When I now attempt to power on the computer, The power light comes on, the three LED's (num lock, caps lock, scroll lock) flash on for a second or two and then go off, and nothing further happens.\015\012\015\012I have been all over the Dell Knowledge base on their support web site, and have run through all of the end-user diagnotics that I could find. I found an article that describes how to generate LED diagnostic codes holding the key down for a second or so as I turn the computer on. When I do that, the LED's show the following: NumLoc constantly flashes green (and will do so for as long as I choose to leave the power on), while the CapsLoc and ScrollLoc are constant green (no flashing). I haven't been able to find an answer as to what this combination indicates, although I am tempted to say that it's video related. This Dell D620 has the Nvidea graphics chip.\015\012\015\012I am looking for a definition of the diagnostic code described above, and some direction on how to fix the problem. Before you ask, you should know that the computer is out of warranty.\015\012\015\012Thanks in advance for your assistance.\015

Answers :

If two of the three leds are flashing (the one on the left stays solid and the two other blink) then this is a no memory error and its likely the memory is not seated properly.

Remove the memory from under the keyboard and try one DIMM at a time in the slot on the back of the computer. Once the PC is booting again reintroduce the DIMM under the keyboard. Like the previous poster indicated the memory needs to be well seated.

Worked for me...


I upgraded ram on a D630 and when I powered the system back on, the caps lock light flashed 45 times and then died. Turns out I hadn't pushed hard enough seating the memory modules (aside, one is under the keyboard--to remove the keyboard, you have to pry off the hinge guard, the plastic strip across the top of the keyboard where the power and sound buttons and lock lights are. Do it carefully--a manual says use a plastic scribe--cuz you don't want to break the plastic). The modules should be pushed in far enough so that the tabs on the ends of the clips fit into the notch on the memory stick. I thought I'd pushed plenty hard--wrong!
