Dell inspiron 5584 (with latest bios and drivers) and windows 10.
I noticed that the laptop wakes up from sleep every 180 mins !!
event log shows messages like this:
The system has returned from a low power state.
Sleep Time: 2019-09-10T16:12:21.970600800Z
Wake Time: 2019-09-10T16:42:42.068844300Z
Wake Source: Device -ACPI Wake Alarm
After tracking the issue thourghly, i discovered that it's related to the power profile setting hibernate after 180 min.
The issue that the system never goes into hibernate after the time specified and continous cycles of sleep and wake up continues till the battery reaches critical level and the system will intiate the hibernate.
what do you think of this problem and what could be the soultion to allow the approriate hibernate function after X time ?
I have the same exact issue, same Wake Source of "Device -ACPI Wake Alarm" and have been trying to find a solution for months without luck. Running an MSI notebook here.
The problem after alot of searching and testing seems related to the function of Hibernate after 120 - 180 minutes.
The problem vanish for my case if hibernate after set to never or 30 minutes.
Can you confirm if these works for you also?
