Compaq je do nedavno imao "svoj" raspored žica (napona) na glavnom 24 pinskom konektoru napajanja pa pripazi ako budeš mjenjao psu sa standardnim.
Usporedi sam:
ATX (ATX12V) 24 pin power supply connector pinout i
Compaq 24 pin power connector pinout.
Clearing and Resetting the CMOS
1. Turn off the computer and any external devices, and disconnect
the power cord from the power outlet.
2. Disconnect the keyboard, monitor, and any other external
equipment connected to the computer.
3. Remove the computer cover or access panel.
4. Locate, press, and hold the CMOS button in for 5 seconds.
