Problem is blinking power led only
i don't know exactly if it's s145-15igm or s145-14igm
have a backup bios file but i dont know the serial.. coz text already erased at the back of the cover
Mother board : fs440fs541 nm-c111 rev 1.0 2019-01-08

Already tested some of posted bios here
S145-14igm - success but invalid serial and not booting on OS
S145-15igm - success with serial and some other info in bios but still not booting on OS
already tried installing new windows but always booting on bios setup
windows installer flash drive detected on...
