Poco X3 suddenly bricked

Hi folks,

I really hope someone is able to help. I got a Poco X3 from a friend which is causing issues. According to her the phone started to lag and shut down yesterday. No pending updates. The phone had about 10% battery left.

After the phone died she plugged it into the charger and the battery symbole appeared. after that the phone went black again and never came back to life.

I tried doing the usual "let's try to fix it" but nothing seems to work here.

I've tried the following things:
  • pressing the power button for 10+ seconds
  • pressing power + vol down for 10+ seconds
  • pressing power + vol up for 10+ seconds
  • pressing power + vol up + vol down for 10+ seconds
  • plugging it into the pc and checking if the device can be accessed using the explorer
  • plugging it into the pc and checking for adb weather or not the device can be accessed
the phone hasn't developer settings enabled as far as I'm able to guess.

the strange thing that I noticed:
when plugging it into the pc the windows sound for a connected device plays. within the device manager a new entry appears:
Code:
QUSB_BULK_CID:0404_SN:812DDxxx
Any ideas how to fix this issue?
