Aurora R8, suddenly won't power on

When you press the system power button do any of the fans turn on? Have you tried pressing the PSU button and the system power button at the same time, there have been posts stating that the system powered up with those steps. Check all the internal cables and also try reseating the RAM. I have seen RAM that is not fully seated cause a no POST and no fans. The most obvious would be a problem with the case power switch. You can also try disconnecting the power connections from the PSU to everything except the MB. If the system powers up then one of the components is the source of the problem. Connect power one at a time to those components until the no power condition returns.

Thanks for the reply.

When I press the system power button (alienware head) nothing at all happens. Its like you don't even have it plugged into power at all.

Yep I did try pressing both the PSU button and the alienware head power button at the same but no difference. I hear the fans turn on but soon as i let go of the PSU button the fans shut down.

I dont know if I feel comfortable to go inside the PC. I've actually never opened the case up since I bought my Aurora.

Today I didn't do anything beside play a few hours of Star Trek Online. The only thing I can think of is could possible updates have caused the problem? I do think Windows did some updates which required a restart and I noticed during the restart my PC turned on and off a few times in a row before it powered back on and through to Windows. I'm feeling that was a BIOS update perhaps now come to think of it? Also Dell Support Center was popping up with some driver updates etc. But all updates were completed in the morning and my PC was still on for at least 4-5 hours and it was working perfectly. Problem happened after I powered it down for about 7 hours and after that it will not turn it back on.

I also have the R8 and since the recent Bios and AWCC updates. I've also begun to experience issues with the system no longer wanting to power on when power button is pressed.

Ohh thats not good to hear

I normally dont do BIOS updates but for some reason Windows Update went and did the update on its own

I just did the update and same thing. Spins up and then nothing.

I have not tried that as of yet. Sorry to hear the CMOS didnt fix it either.

I just reset the cmos, no luck there either.

I beleive a firmware (BIOS) update has been done and it was auto forced through Windows Update which ive never seen happen before.

Shows in the history Firmware 0.1.0.17

So now i can not switch on my Aurora via the button anymore.

At the moment Dell support have told me to dis connect the power cable in the back, hold the power button for 25 seconds and while holding the power button insert the power cable in at the same time. This is the only way i can get the PC to power on at the moment.

They have tried to rollback the BIOS update but so far no luck.

Once i switch my PC off i can no longer turn it back on the tradtional normal way

Try Unplugging the computer, waiting like 10 seconds, and plugging it back in. BIOS updated pretty much did the same thing to my r10. Won't fix your problem, but your pc might at least turn on.

Sorry to hear you are having the same issues as me now.
i do feel like its from the most recent BIOS update that has caused this problem now.

Ok so after some remote assistance via the Dell tech support we decided to start rolling back the BIOS firmware.

We tried both versions of 2020 and still no luck, installed version 1.0.9 which is December 2019. Switched the PC off and then I hit the power button and BAM it came to life

So far we have shut the PC down 3 times and all 3 times its successfully powered back on via the front power button.

Also was told that Windows Update should never have done the BIOS update through that app it self. It should have always been through the Dell Support App only.

I can not explain why its went through Windows automatically and neither could the tech support person. He said he would be passing on my information to the Dell Engineers. 

If anyone is having the same issue =
* I suggest giving a go to rolling back to the older BIOS firmware
* To power your PC up make sure you first unplug the power cord from the tower
* Hold down the power button for 25 seconds and while still holding the power button plug in the power cord
Each time I did this I was able to get the PC to power on and boot into Windows even when it still was suffering from the latest forced BIOS update.

I'm going to leave my PC on now for a few hours as i have some work to do and then switch it off. Hopefully tomorrow morning fingers crossed it will power on back normally as it always did.

Thanks to everyone for the replies as that helped when I passed the feedback to Dell showing similar/same issues were happening with other users.

Same issue here. I imagine this will be quite widespread. Most people will have no idea what to do, nor will they know how to properly find this discussion. Will spread this info on reddit.

Also to clarify, I indeed did have to insert the main power cable while holding the power button to get it to power on. 

Thanks for helping to spread the word. Hopefully that i officially reported it and the info gets passes back to Dell's engineers they can somehow pull or stop the update from being forced installed so others won't suffer the same fate.

Looks like its spreading fast indeed and you are correct most people won't realise its from the update. For me i just caught a glimpse of it through the Windows Update that Alienware Firmware (BIOS) was automatically pushed through it. If i had not seen it i would have honestly thought i had a harder malfunction somewhere.

Correct yes you must be holding the power button down at the front and after 20/25 seconds plug in the power cord at the back and once the PC fires up let go of the power button then.

I have the same issue after upgrading the bios to 1.0.17.  I discovered that if I quickly press the power button 3 times, my computer turns on.  Hope this helps until they fix this problem.
