Hi I got a Dell Inspiron 6400 Labtop that isn't powering on when you press the power button.The power led just blinks twice and that's it...nothing displays and the system just remains dormant...Has any one of you guys have any experience with dell inspiron series labtops not powering on with only the power led flashing once and that's it?There is a battery tester button underneath the labtop that would tell you the amount of bettery charge that it has left and it is showing full.So I am very confused and don't know where to start.Can you guys help?

Remove battery and do not plug AC adapter, press and hold power switch for few minutes, then install battery back, try power up see if it works?

Hi,

I had the same problem with a Sony VAIO K15F but it was easy to fix, I just removed the battery, wait a few seconds and put the battery in his place again. It happens twice in a year and a half and then I sell it.

I suggest you to remove the battery, remove the HDD, plug the AC dapter turn it on to see if it stays on.
As another test you can also carefully remove the memory modules and try to turn it on.
The idea is to see if the problem is caused by one of these components.

Well tried all of your solutions and still no luck.But after deeper inspection I have notice that the power led blinks once and the battery led blinks like every 5 seconds.Does this mean something?The power adapter led is on so i guess the adapter is working fine.

I know you found the solution but figured I would throw in a few cents for you.

If the LED light on the power supply is blinking green and you have no POST from your computer, than the charging mechanism on the motherboard is malfunctioning and needs to be replaced.  Dell will replace the motherboard on this system is under warranty.  

Make sure you tell Dell support that your power light on the computer blinks, but your machine will not POST.  Tell them that your ac adapter has a blinking LED.  As a possible solution and for faster repair times, also tell them that you tested the AC adapter on another machine at it works fine.  When you tested the other machines AC adapter on your machine you received the same results of the blinking lights.

This repair is not a User repair item, and depending on warranty Dell will send a technician to your location to replace the motherboard.
