Power LED Blinking with two red one white. XPS L401x

Hi,

 Welcome to Dell community forums.

 I am very sorry to hear about various problems with your computer, I would suggest you to first run the Hardware Diagnostics.

• Run the Hardware Diagnostics Test (PSA)
  -- Restart your computer and hit F12 on the Dell Logo Screen a couple of times.
  -- It Boots to the One Time Boot Menu.
  -- Select the Option Diagnostics and hit Enter.
  -- Check for the error.

If you get any error reply me back to this post. If u don’t get any error code then proceed to Next Step.

• After this update the BIOS of your computer.
  -- Go to http://dell.to/uIo3ef

-- Put in your Service Tag and choose the Operating System.
-- Select the Bios and download the latest Version of Bios
-- Flash the Bios and check.

• Remove the battery and charger/ac adapter/power cord from your Dell notebook, press and hold the power button for 20 seconds to discharge any residual current inside the laptop. This clears your RAM and is like hardware reset.
• Boot in "safe mode". As it starts up press F8, the computer asks you if you'd like to start in safe mode. Highlight "safe mode" and press enter. See if your Dell notebook works normal.

*NOTE: make sure to connect your system to ac adaptor while upgrading BIOS and make sure not to turn off the system while upgrading BIOS.

For further assistance please reply
