Alienware ACT1250, GPU light turning on during sleep mode

Question

I purchased the ACT1250 a few months ago and since purchase i have noticed the GPU light and fan kicking on independently of the rest of the system while the rest of the computer is in sleep mode. This also sends a breif signal to the connected monitors and turns them on as well. Somewhere between 10 and 20 minutes after going to sleep the GPU cycles on and continues cycling on in seemingly random intervals throughout sleep mode.

Is anyone else experiencing this issue?

Alienware Aurora ACT1250 (aka 'R17' )light and fans remaining on during sleep is a known behavior, often caused by 'Modern Standby' or the system failing to enter a deep sleep state. To resolve this, enable ErP in the BIOS, set active fan profiles to 'Quiet' in Alienware Command Center (AWCC), or use hibernation instead of sleep.  Enable ErP in BIOS: Enter BIOS (F2/Delete on boot), navigate to Platform Power, and enable ErP to force low-power consumption during sleep. Adjust AWCC Profiles: Set thermal profiles to 'Quiet' to reduce fan activity during idle or sleep periods. Use Hibernation/Shut Down: Due to issues with Windows Modern Standby, switching from 'Sleep' to 'Hibernate' or fully shutting down is recommended..

Thanks for the reply.

I do not have the ErP setting in my BIOS menu unfortunately.

Switching to hibernate does resolve the issue.

At this point Dell's solution is to replace the motherboard as they believe it is faulty and sending a signal to the GPU to wake, I dont really agree but we'll try that and see.
