I can't turn my PC off!! (Interesting problem?).
I just had freeze using OE a few minutes ago and when I
pressed the off button it refused to die. I took the front panel off and pressed the microswitch? directly and it still remainded on. I the end I had to switch it off at the mains. I checked the switch and it appeared to be 'stuck in' ie there appeared to be no movement. Anyway I tried to pull it out a little but I am unsure if that had any effect or not. I put the front cover on and then I switched it on at the mains, it did not power up straight away as if the switch was still stuck in so I had to press the power on button to boot up my PC as normal. I noticed the on button had it's usual 'springyness' which it lacked when I had earlier tried to switch it off. Anyway the 'interesting' bit, I was curious as to whether I would be able to switch my PC off via the switch, so I decieded to give it a quick press to see if the 'springyness' was still there knowing that I would have a few to hold it down for 5 seconds before it would actually power down. ( I didn't actuallly intend to power it down, just check the 'feel' of the switch. Much to my surprise the screen immediately went black and the box issued three short beeps, "beep beep beep", they all sounded the same lenght to me. I though it had crashed but I gave the switch another press and it came back up directly into windows, right back into this message which I was typing. I think this may have happened before when I was crouching down looking at the CPU fan as it booted it (to see it was running free), I got the same three beeps and I think I *may* have touched the on button with my knee a moment earlier, but I am not 100% sure. Anybody got any ideas on this? It may explain some of my mysterious reboots and perhaps freezes I have been getting, posted in this thread, although the freezes tend to happen almost exclusively when I am using Outlook Express I had been concerned that my PSU was overloaded (only 90W) and that that might explain my reboots. I do appear to have a dodgy power button though, but it might be more complicated than that. I do not know how they work but they are more than a simple on/off as there *should* be a 5 second delay before power down.. A few other points. If my power switch was indeed 'stuck in' then my machine should have powered down after 5 seconds. So... it can't have been stuck in? and therefore must have been 'stuck out' (although I tried pressing the switch directly pretty firmly) And why did I get three beeps and a black screen when I just pressed the off button for a moment? Firstly is anything was going to happen it should not have happened for at least 5 seconds. Secondly if anything did happen it should have been a power down, not the three beeps and a black screen, also windows and everything else was still running ok when I pressed the on switch again, it didn't have to go through the boot process as I expected. So where did the three beeps come from? I thought you only got these at boot up, when the BIOS is doing it's checks. (Am not too hot on the BIOS by the way, is it 'running' all the time so to speak? I presume some of it must be running otherwise my computer would not work?) And anyone explain how the on/off button works? Does it involve an electro-magnetic stitch? Presumably there is a wire going back into the PSU to switch off the power there. Mine is an ATX PSU and micro? ATX case, I understand? that earlier models had a 'live' wire (230 V) coming out to the switch but that that is not the case with ATX's? And does any of this rambling point to a faulty/overloaded PSU? Thanks for any input, it will be appreciated. half_pint. PS When I have posted this I will try pressing the off button again to see what happens. |

PS When I have posted this I will try pressing the off button again to see what happens. Well that was quick!! I got exactly the same thing again, three beeps and a black screen again, 'cured' by pressing the on button again (back into windows). I am going to try again and listen carefully to the beeps. Yep it's done it again (tried twice) three beeps. All sounded the same lenght to me. |

I don't think it was the same sleep mode as when the power management kicks in otherwise moving my mouse would have restarted it again, and the power managment sleep mode doesn't give three beeps. I am unsure if I tried moving my mouse so I will try it now. Two minutes later. Well actually you are right the mouse movement did wake it up, congrats!! Question is why did it go into sleep mode? Is it meant to do this? I have never tried a short press on the power button before so I don't know if it is normal behaviour or not. Is it? Seems like it is? It doesn't explain why I could not switch it off initially though does it? Or does it? Thanks for your help. half_pint - half_solved? |

Start-Shutdown-Standby. Since the PC was crashed as you mentioned in the original post, pushing it couldn't do anything. It had always worked before when windows has crashed/froze. Holding it down for 5+ seconds should always shut it off, but it's not a clean shutdown. It's the same as pulling the power plug basically. Momentary push should tell Windows to do its Shutdown or Sleep (depending on your settings). It will only happen if Windows hasn't crashed. |

What initially happened is windows (OE) appeared to crash, dead keyboard and mouse so I tried to reset via power button but it would not power down no matter how long I help the button in. The button appeared 'dead' to the touch (no springyness). |
