You can run a hardware diagnostic test from BIOS which will result in error code to help guide you in the correct direction. Call Dell and give them the code so that they can order the necessary parts. Having the code in advance will save you unnecessary wasted time having them try to help you run the tests. They will get it fixed fast if a tech is needed. Answer from Innovative313 on reddit.com

r/Alienware on Reddit: Alienware R13 Flashing Yellow Two Times.
March 16, 2022 -

Just now, my Alienware R13 suddenly started flashing yellow two times on the Alien head followed by the usual white. I can still use the computer, but now my Alienware Command Center won't detect FX or something -- so I can't change my keyboard or anything. I've searched this one up and it says something about a memory error or something -- obviously I'm not computer literate at all. I've tried to reboot it but that has achieved nothing.

Getting angered by this. Haven't even used this for a month and it's already acting up on me. What should I do here? I have no knowledge in taking this apart -- as I've bought this thing so I wouldn't have to do that.

r/Alienware on Reddit: Aurora R10 -2 blinking yellow lights - no ram detected
January 11, 2022 -

I just recently got an Aurora R10 and set it up yesterday. Today I started it up and it ran fine for about half an hour then it shut off. Now it will not turn back on and is showing 2 blinks of a yellow light, then a pause, then another 2 blinks. I looked it up online and it says that light code means there is no ram detected. I have opened it up and checked out the memory cards and they are installed correctly so I’m not sure what the issue is. Anyone have an idea?

r/Alienware on Reddit: Alienware 13 R3: Works, but constant flashing amber light even when plugged in.
May 1, 2022 -

Here we have an Alienware 13R3 i5 1050 2GB (Such powerhouse. Very perform.) Works perfectly fine (apart from the occasional total system shut off on battery power when launching in to certain games), it's just that the laptop's power button never stops blinking in the rapid amber "battery is critically low" style, even when plugged in and fully charged. (While charging, the blinking stops and is replaced by the standard charging "animation". I've run diagnostics on both batteries (98% health reported on main), and have subsequently replaced the coin cell battery to try and fix the issue to no effect. It holds a charge and reports back as having 4 hours 43 mins on Battery Saver so the main seems to be okay. Question is: why is the power light in permanent critical-low battery freakout mode? I've already tried the "unplug battery hold power button" thing to no results beyond a need to re-date/time the BIOS. Any ideas on the cause and any possible fixes? Got this laptop second hand so I don't think Dell can do anything for me.

Besides three amber how many white led blinks do you have? Blinking amber—Computer is experiencing a boot failure but the power-supply unit is functioning correctly. The power-status light may blink amber or white according to predefined 'beep codes' indicating various failures. Table 1.

I am not sure but I think it was 3,1 which would be cmos. But if I switch ram slots fro. 2/4 to 1/3 I get no blinking lights so I could be wrong on the color. I was using g skill ripjawsv 3600mhz. I have the original ram as well and put that back in but I can't get anything to come on the screen. Last time this happened I changed the frequency ram to the wrong on in bios and did a cmos reset and worked fine. For some reason when I tried shutting down I got a grey screen so idk what happened.
