[NAME]  Did you try and remove the coin cell battery & let sit a few minutes the re-insert battery Make sure you unplug your PSU before removing the CMOS battery. Also, while the battery is out, discharge flea power by holding in the power button for 30 seconds.
So I purchased my Alienware Aurora R11 back in August, I loved it. Now, I'm not so sure I made the right investment because ever since I updated my BIOS to 1.0.3, any type of additional non-Dell OEM memory RAM I try installing on the Aurora R11, the PC won't turn on. My R11 came with 2 16GB Dual Channel HyperX(FM) FURY DDR4 XMP at 3200MHz sticks, I wanted to add more so I purchased 2 16GB Crucial Ballistix Gaming 32GB (2 x 16GB) DDR4-3200 PC4-25600 CL16 Dual Channel Desktop Memory Kit. It was working perfectly fine, until I updated my BIOS to 1.0.3 yesterday. Initially it wouldn't allow me to update it and was getting an error that I had to put the original Kingston Memory Ram's inside to update the BIOS (which they were already in). Dell technical support suggested removing the additional Ballistix RAM I had already installed for the past several months, and it worked, BIOS updated and PC was working fine, until today. Today I try to turn on my PC, it'll turn on for a few seconds and turn off. I tried everything from the videos that Dell's automated system suggests as unplugging power, pressing the button behind the CPU to test the power supply, everything. I thought it could be perhaps I needed to reseat the memory RAM's maybe I didn't put them correctly, removed the ballistix and it worked. Tried putting them back in, nothing, same problem. I even tried reseating the hyper x and ballistix on different slots to see if the slots went bad, tried leaving the hyper x on and try 1 ballistix memory at a time, nothing. Only thing I can think of is the BIOS update wont allow me to add more memory. Contacted Dell support and we tried reinstalling BIOS, ran a systems check, everything is working fine, it only stops working when I add the additional memory. Now, I'm just frustrated and frustrated if I should even try buying another set of RAM, maybe buying the same brand that came with the R11, but on Dell's website its a rip off. I feel like I'm being forced to buy more from Dell in order for me to upgrade my PC, which a consumer should never feel like this.
