Default This Dell won't shutdown!

I found myself a Dell Dimension 4600 series, In fact, I saw it on the side of the road and thought that looks pretty new so I'll pick it up, lol.

To my surprise, at first glance it actually seems to work alright. It booted up and started a Windows Xp home edition OS.

However, later I went to shut it down and I found that even after it seems to have shutdown completely, the processor and Powersupply fans never go off. The hard drive light also stays on solid, even though the power light has gone off. The only way to stop it is to unplug it, and then as soon as I plug it in again the fans start right back up.

I'm worried that this is a motherboard problem, which of course isn't worth fixing, but I though I'd see if anyone on here had another idea.
Thanks!

I'm having the same problem with my HP Pavilion 7920 "beater". It won't go off after everything is shut down. I'm thinking it might be the power supply. Then after I plug it back in, it won't start up for a while, you need to leave it unplugged for a bit then it'll start up. Then sometimes when I press the power button, it will come on, but nothing will come up on the screen and the cd-rom light stays on. I dunno, I'm going to replace the power supply, I'll let you know.

The thing where it comes on after you plug it back in is a setting in the bios to power it back up after a power failure.

hmmm, yeah I've just been looking in the bios, but only seems to have a couple of power management options which I've tired. another interesting thing it does is when it's "off", it continous to make these strange beeping noises at random that seem to be coming from the hard drive, but even if I unplug that hdd it stays on. hmmm

*edit: unplugging the hdd causes the cd drive to do strange things instead, lol

Lucky! Trash picking can be good though...

Try swapping in a different PSU though. That'll narrow it down.

when its unplugged, push the power button...that should erase all the "memory"

then plug it in and tell me if the fan goes on again

Default Re: This Dell won't shutdown!

holding the power button while unplugged seemed to work, but after a few seconds of being plugged in the fans started again, and now I have both cd/dvd drives unplugged from the motherboard, and while the comp is plugged in the are constantly turning and clicking. strange!

Default Re: This Dell won't shutdown!

I'm not exactly sure... I'll do a check with belarc advisor when I have time later tonight. The last couple times I've plugged it in it's been working right too, wierd. apparently pretty inconsistent, but If I get a hold of a psu that I know works yeah I'll try swapping at see what happens.

Sounds like a PSU problem, my computer did that once, and it was a PSU. however, i don't know about the strange beepings, clicking noises. hahaha, Only thing that went wrong with mine was not shutting off correctly.

Sounds like a wierd problem, but I agree, PSU proly. Or maybe its in the little switch behind the button on the case. Maybe its slightly damaged or something so that it thinks its being pressed. Or IDK, that sounds dumb nevermind, lol.
If you decide not to keep that dell, I'll take it off your hands, lol.

I'd normally say call dell, but considering their support is useless and hard as heck to understand, you're best off not doing that. I'd say try opening up the PC and see if anything looks out of order, also try making sure the power on after power failure setting is in tact, or even try modifying the setting.

You could do a dell chat. Than you could understand them better, its slower, but you could do other things online while talking.

hmm alright. I'll see about swapping the psu then and see. I probably won't try to deal with dell's tech support. I own a dell of my own and let's just say I've had a few bad experiences with their "support". lol. particularly with a lady named Kim who I had to talk with on three consecutive calls.

Default Re: This Dell won't shutdown!

the clicking could be part of teh transformer in the PSU, or a fan going inside it.

nothing can beat gateway's tech support tho. a Customer came into work today with a brand-spanking new gateway that they had to send back three times to gateway because it could not reconize thier harddrive. (in the two months they owned the computer, they were never able to get it into windows once). When the comptuer came back from gateway "fixed" it came with a list of three people who looked at the system and checked things out. three lists and nine different people looking at the comptuer somehow missed connecing the SATA cable to the motherboard. isn't that "hard drive not working 101"?

LOL wow that's very sad. btw, I read that some dell PSU's are different than regular ones, and replacing it with a different one could wreck the mobo... anyone know if this is true?

i know that some are proprietary to the case/ case proprietary to the PSU so only a dell made PSU will fit inside and get a good secure skrew-down on the case, but i have never heard of that before.

Default Re: This Dell won't shutdown!

ok, now the powersupply that I have and intended to try in the dell apparently isnt compatible with the mobo because it won't plug into it, but while I had the dell psu completely disconnected from the dell, I plugged it in to the wall and the fan started right up, isn't this wrong in itself? I thought that not even that should start until it recieved some kind of signal from the mobo or something.

i've seen a few start up by themselves, good ones that is. did it make that clicking while it was not pluged into the mobo?

no the clicking was coming from the cd drives, I was just trying to say that they were spinning and they were making some noise so that's how I knew.
