recently I have bought asrock H97 chipset motherboard. What is strange for me manufacturer has changed default power led behaviour. I have good night led option:
- enabled/auto – power led is off – equal to unplugging led
- disabled – power led is on when pc is on, led is blinking when in sleep mode
There is no classic option:
- led on when PC on
- led off when PC off/hibernating/sleep mode
Blinking can be really irytating, therefore i have decided to change it. To do that one must get moley plug (like old type hdd power plug). Now from red wire (+5V) connect power thru 150 ohm resistor to + plug of power led. Black wire connect to – plug of power led. That is it. Now power led is off when PC is off and on when PC is on.
