m15 R6, 1 Blue, 4 Red power button flashes

Question

Hey,

I recently started getting this error on my system. While playing some games, the power button would start flashing blue and red (1 blue 4 red) and the game would start stuttering.

The flashes go away once the charger is removed and the laptop runs normally. Once I connect the charger again, it starts flashing the same.

I thought my charger was broken but the hardware diagnosis states the charger is fine.

After shutting down and letting the laptop sit idle for a while. Powering back up with the charger plugged in, the laptop shows no issues.

What could be the problem here? The diagnosis report shows no issue with any component and everything runs fine. This just happens sometimes randomly. I could not find anything similar online with an official response.

Please help.

Hi @imavichandra welcome to this free user-to-user Alienware laptop discussion forum.

What is the exact model number of your system? That would be required to determine the precise code explanation.

Thank you for your kind response.

Although the manual states an issue with the flex cable, I find it a little strange.I can use the laptop normally even after the power button starts flashing with the pattern. The diagnostics show no issue with the machine. After turning the machine off and powering on after a while, everything is normal again.

It also happens after a 30 min session of gaming, although not always. I just want to make sure this is the right. As my laptop is out of warranty, I want to be a bit careful with what I order.

Thank you so much though.

Also attaching a video showcasing the issue. The laptop runs okay even after the power button starts flashing. The performance drops significantly when this happens though. Video

Thanks. Replacing the cable will fix this surely? I am a bit skeptical cause the laptop works just fine after a reboot until I start playing an intensive game.

Hi @imavichandra thank you for sharing video and that performance drops significantly.

Support for Alienware m15 R6 Removing the display assembly shows what would be replaced under Dell warranty and how the display cables are attached to the system board. During factory fabrication quality assurance, there is check that display cables are not placed under tension by moving the lid.

If NOT under Dell warranty and the display cable's electrical connection becomes an unacceptable problem for user, the fix is to reseat display cables onto the system board. Installing the display assembly.

If display cables are damaged, Dell is unable to provide replacement LCD EDP Screen display cables. They are available on the internet, by searching on DP/N:-
