Question about Dell Latitude D620 Notebook
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.

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
