I recently moved my computer from one office location to another, and it was unplugged for several days. I hooked up the components, plugged it back in, but when I pressed the power on button, nothing happens. No fans, no lights, no signs of life whatsoever. The power light on the power supply and on the front panel are blinking at a regular .5 second interval (I don't think that was the case before when the machine was powered down) but there is no other indication of activity. The blinking continues after the power cord is disconnected, but gradualy slows and fades out. I checked the line voltage, and it is a solid 120v. The computer is a 2-year old Compaq Presario S6000NX (just one month out of warrantee - God those planned obsolescent engineers are getting good!)
I ordered a reconditioned power supply on line, since it appears that no power is getting to the motherboard, but are there other potential causes for the observed moribund condition? Any recommendations of things to try while waiting for the power supply?
