XPS 8910, power button working, but no LED

Hi I've bought Dell XPS 8910 about a year ago and its working fine. However, recently I've noted that when the power is on, there is no white LED on power button. When I start computer, orange color appears normally for few seconds. Can someone help me with this issue?

Thanks

Re: dell xps 8910 power button working but no light

So you're saying the power LED turns amber and then goes off instead of white?  When you start the PC by pressing the power button, does the power button blink an error code before it goes off? Error codes are on page 131 in the Service Manual.

If the PC is working correctly, it's possible the power button LED failed. If you're still under warranty, contact Dell Tech Support. They can replace the power button module.

And if you're not under warranty, you can either replace that button module yourself (see page 85 in the manual), or just ignore it.

Yes the orange light blinks once when I turn PC on and then the lights go off. PC works fine though. 

Many thanks for help. I'll try it to replace it myself.

Re: dell xps 8910 power button working but no light

Did it always blink amber once before turning white?

The code list says 1 blink =  System board: BIOS and ROM failure

But you said your PC is working normally...?

You'll probably have to order the button module directly from Dell Spare Parts, if you're not under warranty. So have your Service Tag handy when you call them. If you're under warranty, Tech Support should send you the module for free.

Post back and let us know what happens...

Re: dell xps 8910 power button working but no light

I have just experienced the same problem with my XPS 8910. 

I am about 3 months out of warranty, and had my motherboard replaced twice while on warranty for usb related issues.  A few days ago I powered up my computer with no problem.  It performed a windows 10 update, and when it rebooted it booted to a black screen, but I think the power light was lit at that time.  I tried replacing the video card to no avail, but when I plugged my tv into the hdmi outlet on the motherboard everything worked fine.

Then today I ran diagnostics after booting to F12, and it said everything checked fine, and when I rebooted to the hdmi outlet on the motherboard it still worked fine, but when I plugged in another hdmi cable to the video card all of a sudden the video card was working again, but when I re-booted -- the white power light is extremely dim (virtually out), and the orange light does come on for about a second when I push the power button.

I went to "Dell Support Assist", and ran their diagnostic for driver updates, etc, and it wanted me to update my bios from 1.1.5 I believe to 1.1.6 or something to that effect, and I did not do it.

Like I told the OP in this thread, if the PC is running ok, except for issues with the white LED in the power button, I'd just ignore it.

As for the BIOS update, go to the support page for this model and read the details about what the BIOS update fixes and/or improves. Then decide if you want to risk doing the update which has the potential to brick your motherboard. And before you run the update, if that's what you decide, search these forums to see if anyone has reported issues with that new version.

If you run the update without being instructed to do it by a Dell Tech agent (SupportAssist software does not count as a "Dell Tech agent"), and it bricks your motherboard, Dell isn't going to replace the board. Read their policy on BIOS updates here.

Re: dell xps 8910 power button working but no light

Hi guys,

 

Just quick update on my system. In total I've seen three Dell technicians (one from Unisys and two from IBM, both Dell subcontractors) and it took two replacements of motherboard, one of the main chip to finally figure out (and that was by last guy from IBM) that actual problem is - faulty cable leading to the button unit (which technician googled out while waiting for call from Dell online help). Dell online help was very fast and professional, however, though they've failed to recognize what the problem is - and it was not the motherboard failing.

All in all, I'm very grateful to Dell as all this was done at no cost and with very fast response indeed.

Re: dell xps 8910 power button working but no light

As I stated earlier:  I had my motherboard replaced twice on warranty due to usb issues.  After the second replacement, the Dell technician had to walk me through a reinstall of my OS from my recovery thumb drive, and after that reinstall he guided me to update my bios to 1.1.5.  Now I am three going on four months out of warranty, and I am getting a bios/motherboard error.

Do I have any recourse with Dell since they directed me to update the bios?

AFAIK, this is Dell's latest policy about BIOS updates. But, their policy only covers failures that happen immediately after and as a consequence of doing a BIOS update. So if you updated BIOS while still under warranty and the PC was OK after the update, it's been working for at least ~3-4 months since the update. So the BIOS update policy doesn't apply here.

"Replacement parts and products are covered for the remaining period of the limited hardware warranty for the product you purchased." according to Dell's hardware warranty.  So the warranty on the last new motherboard also expired ~3-4 months ago.

So let's try to troubleshoot...

  1. Exactly what error message are you getting?
  2. When was last time you replaced the motherboard battery?
  3. Have you tried clearing BIOS?

Re: dell xps 8910 power button working but no light

The error I am getting is as follows: I push the start (power) button, and it turns on orange for one second then it turns white.

The battery is only a year old, and it tests at 3.6 volts with my voltmeter.

I have not tried clearing the bios.  If I do will that take me back to the factory installed bios?
