Area 51 16, power button flashes 1 Red and 4 Blue

I believe this is the battery overheating. This could be due to things like the system being under extra load, ambient temperature, where you have the laptop sitting. 

Keep an eye on the system temps and see if it's throwing the code at a particular time when temps spike. 

If you feel like there shouldn't be a reason for the battery to get hotter than usual then I would contact Support and get some guidance from them. 

Same thing on my Alienware 18 Area-51 AA18250 that is less than 170 days old.

I'm up around 6+ times of 1 red/4 blue power button blinks.

Holding the power button down for 20+ seconds seems to clear it. But what's the use if it comes back?

Support cases have not helped getting to the root cause.

This is a false error message introduced by the 1.9.0 bios update. It clears if you shut down and start the laptop again. A restart won't help. The new bios released 13. January seems to be solving the issue. 

I have the area-51 16 for reference. 

Same issue on my Alienware 18 Area-51 AA18250 and it seems to occur every third restart like clock work.  Only way to clear the lights is a complete shutdown then restart. Also it's been occurring prior to bios 1.9.  I'm on 1.10 now but haven't done three restarts yet although I'm skeptical it's been fixed.

So this info is per Copilot AI so can't vouch for it's accuracy but posting for FYI:

That 1‑red + 4‑blue flash pattern on the Alienware 18 / Area‑51 (AA18250 board) is one of those maddening “latent” POST‑level faults that only shows up on warm restarts, never on a full shutdown. The fact that it appears every third restart is the real clue — that behavior is characteristic of a latched EC/BIOS state fault, not a failing component.
Let’s break down what’s actually happening and why your AA18250 behaves this way.

🔧 What the 1‑Red / 4‑Blue Pattern Really Means
Dell never publicly documented this code for the Alienware 18, but community reverse‑mapping and board‑level diagnostics show:
1 Red + 4 Blue = EC/BIOS handshake timeout during warm POST
This is not a GPU, RAM, or CPU error.
It’s the Embedded Controller failing to re‑initialize a subsystem during a warm reboot.
On the AA18250 board, the EC is responsible for:
•  Power sequencing
•  Thermal controller initialization
•  Keyboard/lighting controller
•  Battery/AC adapter negotiation
•  USB root hub power gating
When the EC doesn’t fully reset (which happens only on warm restarts), it can get stuck in a “half‑initialized” state. After two clean warm boots, the third restart triggers the timeout and you get the 1R/4B flash.
A full shutdown clears the EC state completely — which is why shutdown → power on never triggers the fault.

🧠 Why It Happens Every Third Restart
This is the part that makes people think the laptop is haunted.
The AA18250 EC firmware keeps a rolling 2‑state latch for warm‑boot power sequencing.
If the EC doesn’t fully reset between boots, the latch advances:
•  Restart #1 → EC state A
•  Restart #2 → EC state B
•  Restart #3 → EC state C → timeout → 1R/4B flash
Shutdown clears the latch back to state A.

@FrancoDT​ Copilot lied to you.

Not true about only warm restarts. I have had several cold starts end up with the 1 red, 4 blue blink sequence on my  Alienware 18 Area-51 AA18250.

I've also had a fair number of cases where I have ended with a pale orange power light that seems to rotate through paler red, white and blue colors.  Had this happen this morning. I had to a bunch of errands so I locked the screen and walked away. Came back hours later and now have a solid bright blue power button.

I'm running 1.10.1 BIOS now. 

I have a support case opened that is with the L3 tech folks going through the logs I have been sending them with screen shots and notes.

Another unexpected issue, for me with 1.9.0 BIOS I was unable to get into high performance mode until 2 minutes 30 seconds after logging in. With 1.10.1 BIOS that time has dropped by a minute based on tests I have been running so far.

@UFP_Enterprise​, interesting your getting it on a cold boot as I only get it every three warm reboots exactly and a cold boot resets it for three more boots.  I haven't seen the other lights you mentioned so that may be a separate issue.  I'll post an update with bios 1.10.1 after three reboots but not holding my breath.

So I just did my third warm reboot on Bios 1.10.1 and sure enough one red and four blue flashing lights again.  Just reset them with another cold boot.

@FrancoDT​ - I ran more boot tests on my AW laptop, 18" AA18250, this evening.

Started it with 6 Windows > Restart then login sequences with no blinking power button.

Next did 6 Windows > Shutdown, power up, login sequences and no blinking power button.

After that last Windows > Shutdown, did a Windows > Restart and bingo, got the 1 red, 4 blue blinking power button.

Did a Windows > Restart then login and the blinking power button continued to blink.

Then did a Windows > Shutdown and a curious thing happened. The laptop did a restart instead! The power did not go out! That reboot took a bit longer and resulted in the blinking power button no longer blinking!

This is with the latest AW Control Center (AWCC) app, BIOS 1.10.1 and all Windows and Dell software current as of 1/20/2026.

As a result of a ticket with AW Support, that is currently at 71 messages going back and forth, L3 getting involved and a dozen+ uploads of event logs, data collection zips, Windows WER file collections, lots of screen shots and Readme files, the display and motherboard are going to be swapped for new parts.

It would be real nice to have the power button not blink, some errors in the event logs not happen anymore and the AWCC app always display all of the performance data.

Fingers crossed.

should I bring my laptop back to micro center after day 14 this started to happen ?

@1_king_down​ - Maybe?

While you may have bought it at Micro Center (MC), who is supposed to do the warranty/maintenance work on it? MC or Dell? Did you buy it with a support contract, if so then who does the work?

My headache at the moment with mine is that Dell has the replacement parts backordered with a delivery date that is close to a month out! Which is ridiculous. Thankfully, the laptop is still able to run. Just get the red/blue blinking power button sporadically and the Alienware Control Center app doesn't display the CPU performance data most of the time.

Just started seeing this on my unit today (just updated the bios last night after not using it for about a month)

1-red 4-blue, starts on a warm reboot but goes away on a cold boot. I take it this is caused by a faulty bios/firmware update and nothing is wrong with our units? Seems to be very widely reported lately for it to be that all of our units are faulty all of the sudden.

@UFP_Enterprise​ I have the accidental damage plan, hope it works if this new laptop is a lemon because today I'm out of the return window 

@Akoi​ - what version of BIOS did you install? 1.10.1 by chance? 

Note that 1.10.1 did not stop the 1/4 red/blue blinking, but in my case I have noticed a reduction in the number of times I get the power button blinking.

I do not know what is causing the problem. What I do know is that Dell is replacing the MOBO, the display panel and a couple of other parts on my maxed out 18" AA18250 laptop.
