Cisco switch not working (alien.top)

I have this Cisco SG300-28 Switch that I bought from an auction a year ago, was working well until it suddenly stopped working for no apparent reason few weeks ago. Removed all the network cables and brought it upstairs. When I plug the power cable with everything else disconnected, all the port lights blink twice and then the System LED starts blinking rapidly around 4 times per second roughly. If I plug in a network cable, there's no light/activity at the switch or pc end, and ipconfig command on my PC says media disconnected. Tried resetting the switch but holding down the reset button for even a full minute doesn't make any difference. I opened it and grossly everything looks fine. Need some help to get it working again. I have no prior experience with cisco or switches.

If you’ve got the serial cable, use PuTTY (or your preferred client) and see what the output says.

Serial cable ordered, will be here in a couple days.

Yeah, seems like the memory got wiped. Maybe nobody ever did a write mem or something
