Help with computer not waking from sleep

[Was_Just19]

@just19: I just tried the suspend option on the pc a few minutes ago and it simply shutdown the whole rig. I do have both that and Hibernate options on the shutdown dialogue.

I don't know how they are termed in Gnome .....  I have Suspend to Ram and Suspend to Disk ..... which makes it very clear what I am selecting .....  never di understand the need for such terms as Hibernate, Sleep and others. Just confusing.

Anyway, when I S2R the majprity of the machine shuts down .......  and the light in the on/off button on the PC flashes. Pressing the button brings it back to life again.

With S2D it is a different matter .....  the existing state is saved to Swap space and then the machine shuts down completely. The power may be disconnected if required.

On next switch-on, the machine begins to boot (without going to Grub screen) and a short way into it, it picks up the saved state and loads it. It brings the machine back to that state much quicker than a full boot here -- I have a lot running so my boot is slow.

The above is my experience on two machines here with several of the recent PCLOS releases.

regards.

So, naturally now I don't get a signal to my monitor. I freaking give up!!!

I didn't even touch the dang gfx card, now I don't even get the DOS screen, totally black monitor. 

When I was trying to remove the heat-sink, I gave it a very light tug and the whole thing along with the CPU came out at once and I had to very carefully remove the cpu from the bottom of the heat-sink. I inspected it and saw no bent or broken pins and no evidence of any damage to the socket.

PC boots with no warning beeps, just no signal to the monitor. I am at a loss.

Just check the usual culprits .......  the cable is still properly seated ......  and most of all that the graphics card is properly seated.

If you have not had that card out recently then pull it out and reinsert it to ensure there is no dust on the contacts.

Yep, just did all that.

I don't get it because it worked this morning, all I did was apply thermal grease to a heat sink. Makes no sense.

It does if the CPU was slightly fried, and giving intermittent problems...makes it really hard to diagnose, but if all the usual suspects have been found to be innocent, may be time to start substituting parts until you find the culprit, could be as simple as one glitchy circuit on the mobo, or a tiny little bad connection inside the CPU. sorry man, i know it's frustrating.

Yeah, it sure is. I don't mind an issue now and then, I expect that, but this has been almost 2 weeks now wondering what in the hell was going on with this bloody thing. I am just at my wits end with the bloody thing but I need to get it working. I wish I could just throw it out the window.

[SuperKev]

I have noticed now that when I plug the pc in- if the PSU switch is on- or if I flip the PSU switch the pc turns on with out my having to hit the power button.

Anything I can read in to that? I don't remember it happening before.

It could be a BIOS setting ......  how the PC behaves after a power out for instance.

Unfortunately it also could be an indication of more motherboard problems 

Did you get the temp situation resolved?

Until that is done I would not use the machine tbh.

After applying the paste and pluging it back up, no signal to monitor- black screen- so I don't know if the Arctic Silver helped or not. I tried a different gfx card and nothing, put the old one back in, still nothing, but it was working prior to my taking out the cpu and applying the new thermal paste.

I did find, and correct, some aspects of the case that where impeding airflow but that had to do with fans and such so I don't think doing so is what is causing the blank screen.

I guess I am going to have to remove the cpu again and inspect it for any bent pins, I did that last night and could not see anything but I am going to take a magnifying glass and see if I can see anything that way. Even though the whole cpu/heat sink came out as one unit last night (don't know how I didn't pull it hard or anything) it did not appear to have any damage- perhaps I missed something. I can't think of any other reason it will not work now.

I am just ready for this bloody thing to work consistently, so I can work consistently without fear of suddenly not being able to access my files.

Any thoughts are welcome.

Is it possible that the locking device for the CPU is not being used or is broken or ..... ?

That would cause all sorts of problems as pins made intermittent connections etc etc

[Dragynn]

Shoot, shoulda thought of this last night, but I think you've exhausted the complex, it's starting to sound mechanical to me, dude you could have a bad power switch, no kidding I have seen this behavior a lot of times. Check your power switch, take the switch itself out and check the connections, look for burns or broken traces. Sometimes the little plastic switch itself can hang juuuuuuuuust slightly on it's housing. Check your keyboard for the same issue, any sticking or partially sticking keys can throw a monkey wrench into the works. Unplug peripherals like the front USB connections and see if it goes away, saw a tiny circuit board burn slightly one time and it stopped the whole system from booting.

That spontaneously turning-on thing you just mentioned is a big red flag pointing to a mechanical problem IMO.

[SuperKev]

yeah, I think you are spot on, didn't have time to touch it last night but when I was moving stuff that was obviously blocking airflow in this "cooler master" case (stuff in the actual case design) I think I did have to mess with the on-off switch mechanism.

I don't really care for this case because it has a door over the CD-ROM's and such anyhow so I may just switch everything to a more traditional case and add lots of fans.

Ok, going to pull out the cpu, again, and check for bent pins with a magnifying glass.

I got the fangs and the one eyebrow now so this bugger is going to work.

[SuperKev]

Bent pin 

Fixed that, applied Arctic Silver and I am on it now, but it did just freeze up on me again so I am completely out of ideas. The CPU does not seem to be getting as hot, staying around 50C which is still warm but within operating parameters as far as I can tell.

Only things I can think are the CPU, MoBo or RAM as I have replaced everything else. Is there a chance it could be software based after all?

[Was_Just19]

50C seems Hot to me ....

Run from a live CD or USB and see if you get the system freezing up.

Have you been running TOP in a terminal so you can see if anything you are using might be causing problems?

[SuperKev]

Unsure what TOP is, can you tell me how to use it? I was wondering if there is some sort of log or record someplace that I can access that might show what is happening when I get the freeze ups.
