Hi guys,

Just recently my XPS 420 stopped working or won't turn on for whatever reason. Before it was working fine during the day but when I got on at night it was turned off and I usually have it on sleep mode with the blue light blinking on the power button. When I go and press the power button nothing happens and Im like oh hell then I take the power cord out and out it back on to another outlet and still nothing. I email dell tech support and I get this message:

The power indicator light
=============================
The power button of the computer has a light that indicates the computer?s condition at the moment. There are five possible states for this light:

No light ? if the power button light is dark, the computer has not even begun to power on. If you press the button but there is no light, the computer is not receiving power. Verify that the power cord and the electrical outlet are good by swapping them or using them with another device. If they are, the problem is most likely a defective power supply inside the computer.

Solid or blinking yellow light ? this indicates there is a mechanical problem with the power supply or the distribution of power within the computer. It almost certainly indicates that parts are not working properly and you will need help from a Technical Support Specialist.

Blinking green light ? this indicates the computer is in a sleep state. Pressing and holding the power button briefly should return the computer to normal function.

Solid green light ? this indicates the computer has powered on normally.

2. Diagnostic LEDs on the rear of the computer
==============================
On the back of the computer you will find a small set of four LEDs. Each of these LEDs can be off, yellow, or green. If none of the LEDs are lit, this usually indicates that your computer has not been started at all.

If you see four green LEDs, this indicates that the computer has successfully completed the POST process. If you have four green LEDs and there is no video on your computer, the problem is in the video card or the monitor. If you have another monitor available, you can attach it to the computer to test this.

Any combination of yellow and green LEDs other than four greens is an indication that there is a problem with the computer during the POST process and it will need further troubleshooting and maintenance.

3. The display on the monitor during start-up
==============================
During start-up, if your computer gives you the option of entering the system setup screen, this is an indication that the computer IS completing the POST process. If the computer loses video or hangs AFTER getting this option, the problem is not in the POST process. The problem may be in the video display, the operating system, or a hard drive malfunction.

Your Dell warranty covers any mechanical failure caused by a defect in quality or manufacturing. You may be asked to do further troubleshooting for warranty services.

I go and check for those things but for the life of me I couldn't find any small LED lights on the rear. The only lights I see is a blinking green light where the ethernet cable goes. Another thing I found was when I opened the panel I saw a small LED light at the bottom right panel-ish that was in a solid yellowish color. Now a few things I don't understand when they say the power indicator light do they mean the small little light bulb? or the front power button?

I already tried lookin in the forums but couldn't find a solid answer so I am trying my luck creating a topic my friend said I might have to buy a new power supply thingy but I'm not sure which kind but I'll do that last and see what happens here.

-Thanks to anyone who respond and I'll give out more detail if needed.
