Question about Dell Latitude D620 Notebook

3 Answers

Dell D620 power light comes on when pushed but goes out 5 sec lat

My Dell D620 laptop will not boot. When the power light is pushed to start the laptop the power light stays on for about 5 seconds and goes back off without booting the system. I have tested, with the same results, using an external power supply. I also removed and reseated both RAM modules (separately) which did not help and then tried pushing the "FN" key and the power button but do not get any trouble code lights (neither solid or blinking). If I continue to hold the power button down the power light will blick at 5 second intervals while it is held. Does anyone have a troubleshooting suggestion that could be tried next? Thank you -

There are two common causes for this and both relate to the power supply.

First is that the connector on the main board is loose or has a bad connection

If you are proficient with a soldering iron this is an easy fix for approx $10

They have some very good step by step guides for replacing power sockets.

It could also be a dying power supply which is the second most common cause.

Replacements are easy to obtain and cost between $20 to $60.
If it is the PSU either get an original replacement (EBAY is best bet) or get one of the many multi laptop PSU's available but if you get the latter please make sure it carries enough or preferably MORE amperage than you need.

The old supply will have the details of both the voltage and current on it and you need to match the voltage exactly and keep the same or better current rating eg 1000 Mw or 1A or whatever it says.

    Make sure you look for your particular brand and possibly model on the "insidemylaptop" site

    Whilst they dont cover all models many of the instrucions are close enough to get you stripped down enough for a repair.

    Reply with your make and model and I will try get you closer to what you want.

    Sorry if Fixya crunches up this comment its a known bug on the site

Hi ! this is a well known issue.
Any AC adapter converts Ac to DC power and that dc power gets transmitted into the power unit that helps in charging battery and also supplies power to all parts on the system board.
If there is any fault on the power unit on the board the adapter led goes off indicating shot circuit or in other terms can be explained that the charge transmitted through the DC adapter cable is returning that will heat up the adapter as well and the indication for the adapter LED going off is a clear symptom for a faulty motherboard.
Finally no matter what you do the only resoultion is that you have to get the motherboard replaced .
This Solution applies to all Dell branded Portables/Laptops/Travel books

My D620 starts to boot up then shuts down suddenly

could it be that your battery is no longer holding a charge?
try powering it up with the power pack attached (and ensure the light on the power pack is indeed lit) - it also could be that the laptop is not being charged by the power pack.

You may need to replace the cmos battery, its a cr2032 3v button cell
Make sure all your expansion cards and memory are reseated.
Make sure all cables are reseated.
your power supply could be bad

If that doesn't work try this

Here is my fix for the dell dimension 4400 amber light problem. It works!
replace cmos battery.
then unplug power cord form wall about 5-10 secs.
then plug it back in, wait 5 secs.
If amber light comes on, press and hold power button until it goes out.

(with light out, press and hold power button while amber light comes on and goes off again holding power button 2-3 secs after light goes out.) repeat whats in parenthesis until computer turns on
it should only take about 6, 7 tries.

After the computer boots, you may want to setup cmos or boot into windows.
After you shutdown, unplug power cord for 5-10 secs then plug it back in.
Press and hold the power button, computer should come on.
I found that's the only way to turn on the computer.
If you shutdown and don't unplug power cord the computer may not boot, mine didn't.
Strange I'd say
