Hi joe,

I must appreciate the ease with which you are handling this technical issue on your computer.

Please try the below steps to isolate the problem:

1. Remove all the external peripherals, the power cable from the computer. Press and hold the power button for 20 seconds. This process will drain all the static energy from the computer. Reconnect the power cable back in the computer.
2. Now try running diagnostics by switching on the desktop computer by tapping F12 at dell logo to enter “One-time boot menu”.
3. If the diagnostics displays an error, please reply with the right error message.
4. If unable to run the diagnostics check for beep sound or flashing lock lights when the system is turned on.

Please reply the results along with the beep sounds, link lights patter on the right side of the screen and errors on the screen.

Thanks for replying Nikhil D.

Unfortunately, not being able to see anything on the screen precludes me from being able to tap F12 at the Dell logo.  But, I went ahead and tried everything you said to do anyway, hoping I would at least see any flashing lock lights on the monitor or hear beep sounds ... of course, I did not.

All I get when powering on the monitor is the immediate turning on of the inner fans, a blue power light, and blue monitor power button (which will not turn off when pressed).

So, to sum up:  No beep sounds. No flashing lights pattern. No picture/video/screen activity, so no error messages that I can see.

This is quite frustrating to say the least.  Any one else out there can help me?

Hi Joe,

The issue appears to be a problem with motherboard of the computer, which needs to be replaced.

If the computer has active warranty, I would be glad to arrange a service on the computer.

Hello Joeytheg. Ironically I am experiencing the exact same issues that you are experiencing.

It is driving me crazy and without anything on the screen I am helpless. If you do in fact find a solution

to your problem would you please let me know what this problem is. Thank you so much. If I find out anything

I will let you know as well. I had read that these symptoms may contribute to the CPU being burnt out from 

overheating. I had taken out the fan and the thermal thingy which is directly behind the fan and that thing was completely full of dust

I had noticed that the top of my system was real hot at times but thought that was normal. Now I am thinking that it wasn't. So this leads

me to believe that the CPU is a strong possibility of this cause. But I am not definite of this.

Please let me know what you find out ok? 

Thanks Joeytheg! 

Hello,

I have a similar pattern except that when I turn my XPS One on, the long blue light and the smaller blue lights all blink together every 4 seconds.

Please HELP me understand what's going on and if it can be fixed.

Thanks

Conrad

I have a Dell XPS One (A2010) that started out never posting, and a blank display.

Based upon my experience, I determined it was most likely a video card issue.  I got a replacement and the system would post and there was hard drive activity consistent with the OS booting, but only a blank display.  It would also shutdown gracefully after pushing the power button for a second.  

I then tried the next cheapest part to replace, the inverter.  No change with the replacement inverter.

Recently, I purchased a new display, and no change with the new display.

So I am pretty much to the point of replacing the entire motherboard, but I thought it was worth asking here if anyone else has had this issue and what the resolution to their problem was.  

conradspa the blinking lights PROBABLY indicates a bad video card.  That is what mine did anyway.  Replaced that and I got the system to POST but still no display for me.

Also, I have now replaced the motherboard and still no change.

In short, started with no post, no display, no hard drive activity.

1) Replaced video card, have POST and hard drive activity, no display.

2) Replaced inverter, no change.

3) Replaced LCD, no change.

4) Replaced motherboard, no change.

What else could it be?  

TRY this most simple of ALL solutions. Replace the battery on the motherboard - a little CR2032 battery. Booted right up. I literally took this thing apart and tested each component separately and found nothing wrong with them. Then in some obscure forum I saw someone say something about this CMOS battery. So I changed it, put the system back together and voila, IT WORKS! Amazing that something so small and insignificant can bring this entire machine to its knees and Dell has absolutely no help on this subject. Shame on you Dell. Good Luck folks and let me know if this did the trick

I'd be interested in the testing methods because I just replaced the CMOS battery and so far, no change.  I haven't tried every combination of my replacement versus original equipment however.  

If there are other tests I could run, I'd be interested.
