Compaq Presario shut down problem
My friend gave me his Presario saying the computer would shut down anywhere from a few seconds to a couple of hours after start up . My first thought was the power supply was going bad . I replaced with a known working power supply and the same problem occured. At that time I thought maybe it was the O/S so I replaced the hard drive and again the same problem . At that point I thought the on /off button on the front of the computer was bad . So upon pressing the start button and letting the computer power up ( fan starts turning) I disconnected the on/off button connector from the motherboard . The computer now runs fine . In windows I can restart the computer or put it in stand by mode with the on/off switch disconnected from the m/b . The computer simply cannot be powered all the way down without having to reconnect the on/off button and going through the above procedure to get it to boot again. My thinking perhaps incorrect is the on/off button is not a traditional switch in the mechanical sense . Is there some electronic board ( m/b perhaps) controlling the switch that is bad and how difficult is it to replace . I hope my friend can live with the computer in it's current set up but I doubt it. Your help is deeply appreciated Mason |

The computer simply cannot be powered all the way down without having to reconnect the on/off button That is odd, it should shut down without the switch connected. Likely the action of the switch hasnt been configured properly in the OS. and going through the above procedure to get it to boot again. My thinking perhaps incorrect is the on/off button is not a traditional switch in the mechanical sense . I havent noticed one that isnt on that sort of case. Is there some electronic board ( m/b perhaps) controlling the switch that is bad Looks like its just badly configured so that you cant shutdown completely without using the switch and a bad switch. The action of the switch is specified in both the bios and in the OS with most systems. It may have got installed with the wrong ACPI setting too, that may be why you cant shut down completely without using the switch. and how difficult is it to replace . Quite difficult to get one that will fit mechanically quite a bit of the time. I hope my friend can live with the computer in it's current set up but I doubt it. Yeah, rather an awkward config. It may well be possible to reconfigure the action of the switch so it can be shut down completely without using the switch but that isnt necessarily very useful if you want to run without a switch. It should be possible to configure it to start on power on without using the switch, but that might not be possible, depends on motherboard bios. Thanks for your responses the computer can be shut down without the switch being connected . I should have written that you have to reconnect the switch to the motherboard to boot the machine after a shutdown which is cumbersome . Yeah, that makes much more sense. Does me clarifying the situation give anyone a better idea of what the solution might be ? Yes, I'd use the reset switch if the main power switch isnt easy to replace because you cant find one that is mechanically suitable from a discarded case. If the owner doesnt like the switch change, quite a few systems can be configured to start on power being applied to the power supply mains input, in the bios. I will look at the reset button and see how difficult that is to wire up . Its normally pretty easy to change them, but I forget what the Presarios do with how they are wired to the motherboard header for the switches. |

Thats quite a bit quicker to start than a normal boot and you should be able to configure the Presario to come out of hibernation from the keyboard or mouse. Maybe that combined with swapping the switch with the reset switch would provide a pretty decent result. |
