Frequent random power loss Acer Aspire E5-575G-57D4
The laptop randomly loses power while on battery. It is independent of demand on the system resources. It is also independent of battery level. This is a persistent problem.
All power cuts: the screen and keyboard backlights turn off, all sounds go silent, and it stops responding to input. It is a full, instantaneous power loss (aside from CMOS battery, of course). The issue occurs sometimes while the system is in use and sometimes while idling. The system does not power itself back on; I must press the power key to boot it up.
For each occurrence, Windows system log shows critical kernel power event ID 41: "The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly." Of course, this log entry is created once the system is powered on again and finds it had not been shut down properly.
Acer Care Center update says all is updated. Windows update says all is updated. However, I checked the system info and found the BIOS was version 1.25 while the most recent version available is 1.29. This morning, I stepped up from 1.25 to 1.27 and then to 1.29, so it is now up to date. I am currently using my system for its daily use on battery power. If the problem recurs, I will update.
