Question about Dell Inspiron 6400 Notebook

Dell Inspiron 6400 laptop will not power up

When I try to power up the laptop all the lights come on as normal but go out after about 3 seconds. The power light remains on but nothing happens. This problem started about 6 months ago. When it first started if you tried a number of times it would then start ok, but it has now got to the point where it will not start at all. I have tried stripping the computer down and reseating everything including the CPU, swapped memory cards around, tried with and without the battery installed and disconnected every device one at a time, all with no success. If I hold down the Fn key when powering up, the 3 lock keys indicate that there is a cpu error code. This code was evident when the computer was intermittently working. Has anyone else had a similar problem or any ideas of what could be wrong? I am reluctant to purchase a replacement CPU without knowing for sure if this will solve the problem. Thankyou in advance.

Laptop doesnt boot only power ligth comes out when press on buttom a ligth comes out but nothing on the screen i dont hear the fan keep going.


Maybe there are some problem in your start button (the button wire connect to mainboard is Loosening.

Please press the start button for about 3-4 seconds then see it would start. Always it may solve the problem, this happend to my inspiron 6400 too, after used for years the start button failure. It shows only power lamp lights green but the other light cant light red.

If no, maybe your must change a power supply, as the lower volt current cant start all the device.

Dell Inspiron 6400 Power Problems


Sounds like the power pin is either loose or damaged. . . .Happens from jerking or tugging on the cord too much.

Once you get it fixed you need one of these. . .
