Default HP 15 power led blinking .

hi everyone
i have HP with motherboard DAR62CMB6A0 rev:A
the power led turn on and off (start and restart no fun spinning )
3.3v on ec bios but not exist on main bios ,
but after i press the power button the 3.3 v appears on main bios
i try to flash the main bios but the bios programmer can't recognize it i try with different programmer and the same problem ; i think the bios ic(EN25Q32B) is damaged , i use MX25L3206E as replacement but the same problem .

Usually on a R62 mb , dc jack light blinking is due to resistor failure. I solved this case few months back and it was resistor for sure. Dont remember exactly but the resistor was located somewhere between power switch and vga port. Hopefully, you can find out.

Have you taken the main bios chip from the motherboard ??And then tried to flash it with the programmer ??
What programmer are you using ?

Sometimes it is not possible to program the bios chip (sitting on the MB) with a cable and a clip ...
You may need (to buy ) another programmer to do it in this way ..
