I’ve had my R3 for nearly 4 years now and had to replace the fans twice, but the other week I noticed the CPU fan wasn’t spinning and after running a Triple A game (cyberpunk) for about 2 hours and started to notice the keyboard getting warm on the left. I ran BIOS diagnostics then noticed the CPU fan wasn’t detecting at all.

after trying a few basic things like unplugging the battery and holding the power button 30 seconds I decided to take everything apart again till I got to the fans again and everything seemed fine after checking all connections, I always watch a dell employee video on youtube for disassembling the laptop and made sure I did everything correctly.

After booting the laptop back on the GPU fan runs as usual aswell as the custom lights coming on but no beeping or display on the screen, just 2 red flashes and 3 blue indicting no memory/ram even though the RAM sticks weren’t messed with. After some basic troubleshoots such as reseating the RAM, switching spots, trying 1 RAM at a time.. holding D while pressing the power button, unplugging the battery and holding the power 30 seconds. All these didn’t change anything 

Then I decided to try and take it apart once more because someone suggested resetting the CMOS battery so once I did that (unplugged and replugged) and then tried turning my computer on I get the same 2 red 3 blue LED first then after it just flashes 3 red 1 blue indicating the CMOS battery failed? 

At this point I’m wondering if maybe the motherboard is just fried (maybe from overheating while trying to play a game before noticing the fan wasn’t working, but it didn’t get that hot compared to how hot it’s been before, and I received no warnings about the fan or overheating, I just ran a BIOS diagnostic and realized it wasn’t detecting after noticing it wasn’t spinning) but then again not sure why the fan didn’t work in the first place. The reason I had to replace the fans last time was because after trying to carefully clean them with a compressor the CPU had blades break off)

 I’m now thinking I’m about to have to toss this laptop in the garbage and buy a nice custom rig, if anyone sees any hope for this laptop or has a good idea what went wrong please let me know
