If the LED on the power supply goes out on connection to the system, it means the system board is faulty.

Same problem with me!

I was using my dell XPS L401X and suddenly it goes off and do not turn on again. I'm also Brazilian, it should be Design  problem.

My AC adapter turn its blue light on, but when I plug it in laptop the power AC/Battery LEDs do not turn on. Power button doesn't respond.... laptop is DEAD!!!!!! DEAD, DELL!!!! A 1 and a half year laptop DEAD!!!!!!!

Dell NEVER again!!!!

Same problem but little variation

Laptop's power buttong stays on but laptop is not responding. no display no other activity.

please help us to get out of this situation. i bought it from US.

Hi dineshprjpt,

If the power button light indicates solid white it means the system is getting power and the issue could be with the LCD or the integrated video card. Lets try these steps to isolate the issue further.

1. Connect an external desktop monitor to the laptop and switch the display by pressing Fn and F8 on the laptop.

2. Run the LCD built in self test (LCD BIST) using this link: http://dell.to/UMTbOO

3. Run the Dell hardware diagnostics using the below given link: http://dell.to/Kf9wXD

4. Make a note of any beep codes during the start up process.

Please reply with the results.

It got started one day and ran the diagnose utility and got the error of fan speep RPM = 0. what can be the best replace the fan or motherboard?

Hi dineshprjpt,

Replacing the fan should help in fixing this problem. Please click on my username and add me as a friend. Send me a direct message with the service tag of the computer and name of the registered owner. I will be able to check the warranty status.

With an active warranty I can arrange the replacement of the parts needed.

Hi dineshprjpt,

I have responded to your Private Message. Please check the same.
