m15 R4, power light continually blinks red
Alienware m15 R4
Hey I have an Alienware m15 R4 that when the power supply is jacked in, the power light blinks red continuously.
Some history: when this issue first occurred I was using the computer and it shut off with the light flashing red then stopping and the light on the power cable turning off as well. The connection of the cord to brick has always been loose so I replaced the power supply, thinking it faulty.
With the new power supply when I plugged it in, the power button still flashes red but it doesn’t stop until I unplug it. What could be the issue here and how would I fix it? I’m thinking if the issue was the power supply then the laptop should turn on when the power supply is connected, no?

A blinking red light indicates that the battery has a low state of charge and it will not start the laptop.

Hi @FlipperEar welcome to this free user to user Alienware laptop discussion forum.
Do you have a counterfeit ac adapter or charger that is not Dell OEM branded?

Hi @FlipperEar Dell support for Alienware m15 R4 System-diagnostic lights does not include power light blinks red continuously. Laptop without battery is designed to function as Desktop on ac adapter (charger) power. If battery is disconnected (not removed) does the laptop work?
