After a few hours power outage - the speakers Presonus Eris E 3.5 BT aren't turning on. the blue light above the volume knob isn't turning on at all, and there's also no "pop sound" as usual, upon plugging into an outlet or starting the laptop.

troubleshooting:

- tested playing audio through laptop speakers, as well as external monitor's speaker - both work and play audio.

- tried updating the audio driver - it's already the latest.

- tried unplugging every single cable from all devices, and all outlets related to the laptop, Eris E 3.5 BT, external monitor etc. for a few minutes to drain residual power, and plugging back in - no result.

- the blue light isn't turning on.

- tried plugging the speakers into different outlets, which work for other devices - same issue.

- tried switching the "power" switch on the right side of the left speaker many times - no result.

- tried searching for the speaker's bluetooth through Windows - didn't find it.

- tried pushing the bluetooth button on left speaker's back many times - no results.

- visually inspected the speaker cables (power, 3.5 to 3.5 mm cable, connection cable between left and right speakers) - no damage visible.

other info:

- speakers were never exposed to other damage like drops, water, or any other kind. I never move or change the setup, they always stay in the same place. Only stopped working after this specific power outage. Speakers were plugged into the outlet at the time when the power went out, as well as when it came back on.

- laptop and external monitor were plugged into the same extension cord as the speakers, no damage to either of them.

- power outages have happened before, several times, but there was never an issue, not even temporary. All other conditions (setup, cables, were the same during the previous outages.)

- I'm using the speakers as regular PC speakers for music, movies, internet videos etc., not for studio monitoring, or video editing or similar.

- Speakers always play at about 10% volume. (Physical speaker volume at 50%, Windows sound level at 20% or less.)

My setup (always been the same):

- laptop running windows 10, usually up to date.

- External monitor connected by HDMI

- Windows sound setting is set to send audio to the laptop speaker >  laptop's "Audio OUT" port is connected to the Eris E 3.5 BT "Audio IN" port by 3.5 to 3.5 mm jack cable. Eris E 3.5 BT is plugged into a power outlet, and the stock red/black speaker cable is connected between left and right speakers.

I understand it's probably because of the power outage, but not entirely sure since it had no problem after previous outages.

Please suggest what can be the problem and how to solve it.
