testing compaq power supply ?
I inherited a compaq presario that had just gone dead, no fan on power
supply no boot up, nothing. I installed a new power supply from compaq and still nothing. I just read there is a turn on terminal for some power supplies, either this thing is not being turned on or I received a defective power supply from compaq ? How do I test this power supply out of the 'puter ? Kevin Falconer Fort Myers, FL |

To test the PSU if a standard ATX, you usually have to take the green pin # 14 to gnd and put a load on the 5v line (about 0.5 amp). If the compaq is a proprietry thing you might find help on www.hardwarebook.net/connector/ have a look in any case it's a handy source of info. -- Regards ............... Rheilly Phoull |
