Z3 always boots to fastboot mode only when it connected to pc



"Z3 always boot to fastboot mode with blue led only when it connected to pc"
and otherwise i can not even start the phone via power key cuz it doesnt work when phone is off.
but power key works only if it is connected to pc and screen will be open at the same time.

what kind of brick is this? what could i do before let it to service.

i have flashtool installed on my laptop.
i checked phone can be on flash mode via fastboot but i dont even internet to dowload some OS to flash it.
flashtools "reboot device into system" key. i tried it does nothing.
