Power irregularities

Recommended Posts

Hi allThe new/old computer seems to have a mind of its own re Starting up--->>>It is plugged into a KVM and a protected power bar (with two other deskies)I always switch the power bar off at night and on first switch on the next day power lights up on the new/old CMStorm desky and it boots up without any prompting from me.But when I shut it down it WILL NOT POWER UP AGAIN until the power bar is shut off and restartedSo whether there are gremlins or other forces at work here would love to hear some comments pleaseDon't know if this will change as this computer is about to have all both hard drives deleted then re set up with XP Win7 and also Linux but though I'd explore this before taking the plungeCheers for YearsColin :)

First thing I think of is an option in the BIOS. Have a look in there Colin. Obviously there's a setting which boots up the machine after a power failure: after a normal power down and a switch off power like you're doing, the BIOS sees that as a power failure: after you switch on the power next morning, the BIOS detects that, and boots up after the so called 'power failure'. Set this to off and your problem is gone.

StrikerHere's the reply I got from the seller and what I did after that--->>>Hi again with respect to--->>It's a setting in the bios, the computer defaults to the last power up status (ie 'Prior Power Up Status'. So if you turn off the power bar, it looks to the computer like the power failed and it turns itself back on once the power comes back. If you shut it off via windows, the computer knows you shut down manually and stays in the off state when power is reapplied. Your other computers likely have this option defaulted to 'Off'--->>>Booted into windows - shut down via windows rebooted and Went into the bios tuned off the after power shut down and and NOW IT WILL NOT BOOT UP AT ALLANY SUGGESTIONS PLEASECheers for YearsColinAny ideas too PLEASECheers for yearsColin :)

What kind of BIOS is in there Colin, Award for example?BTW: With the computer powered down, pull out its AC cable from the power bar and reconnect it to an AC outlet without any power bar or something like that temporary.Next push the computers on/off switch: it should power up now.See what BIOS is in the machine.And what OS are you running on it, XP or Vista or maybe Windows 7RC?

StrikerIt is Phoenix Award Bios And OOPS!!! :"> repositioning the plug did not workHere's the latest from the seller and my reply--->>>Find the battery inside the machine and remove it CAREFULLY and let the machine sit for 30 minutes, then replace it. That =should reset all the bios settings. I recommend you don't alter the BIOS settings in case it does something just like this again.My reply--->>>Can't find battery anywhere in the MB Manual but I'll look inside the case and have you any idea where the battery would be and what it would look likeGetting to be quite a saga this one :"> and just wehen I got XP and PCLinuxOS 2009.2 Gnome on it and preparing for Win7 and maybe another Linux flavour oh well suppose that's what life is about all these CHALLENGES :) Cheers for yearsColin :thumbsup:

Here's how such battery looks Colin:http://www.pcbuyerbeware.co.uk/BIOS.htmIt's the 3rd picture from above, mentioning (in this case) Sony CR2032.Here's another article with a bigger picture:http://en.wikipedia.org/wiki/Nonvolatile_BIOS_memorySo you are in contact with the seller, is that right?

Yes StrikerrAm in touch with the seller (got in on Ebay) and am happy with it up to now even with it's little quirksThanks for those pics they give give me some idea what to look for --->>>Hope I do not have to change jumpers thoughHave looked for pics on the Asus A8N-E mother boars showing the battery but no success as yetCheers for yearsColin :)

OOPS!!! Found a pic for the A8N-E--->>>http://www.thetrailingedge.com/images/prod...s-a8n-e-big.jpgCheers for YearsColin :)
See those three white connectors on the mainboard at the left upper quadrant? Just below them between connector one and two: that's the battery.I do have an ASUS A7N8X-X mainboard here, it's in big lines the same as yours. The BIOS:While booting the computer hit DEL, after a sec or two you'll enter the BIOS options screen.Goto Advanced > goto Power Management SetupHere are my settings which work perfectly:
ACPI Suspend to RAM: [Disabbled]Video Off Method: [DPMS Support]PWR Button < 4 Secs: [soft Off]Power Up On PCI Device: [Disabled]Power Up On Ext.Modem: [Disabled]Automatic Power Up: [Disabled]AC Power Loss Restart: [Disabled]Power On By PS/2 Mouse: [Disabled]Power On By PS/2 Keyboard: [Disabled]
Above I marked the two settings you need in red.After setting these like shown above it should just work in default state, that is: powering down through Windows shut down dialog, next day the computer won't restart automatic: you have to hit its power button to start the machine. :">

StrikerI can NOT get into the Bios can NOT power up the machineEVEN after as suggested from the seller take out the battery for 30mins - replace and try again.Had it out for 40mis--->>>It will NOT POWER UP in either wall socket or Power bar I did this from Bios before--->>>AC Power Loss Restart: [Disabled] because it was enable But do NOT remember what this setting is --->>>Automatic Power Up: [DisabledAm going to remove the battery again for an hour this time and see what happensCheers for yearsColin :thumbsup:

If it doesn't do anything at all, then I suspect another problem. (faulty power supply or something like that) Whether the battery is full or empty doesn't matter, the computer should just power up. With an empty battery all it does NOT is remembering the settings for the BIOS, but it should power up nevertheless.I suggest to open up another topic 'machine will not power up' and mention all you did until now.BTW: At the back of the power supply, is there a switch by any chance? And maybe it's in the 'off' position?

Striker I was beginning to think Power Supply myself :"> but do not really want to think thatAnd yes the switch ON/OFF on the back of the case is ONCheers for yearsColin :)

OK Colin, I was just perusing the User Guide for that main board: page 1-21: Clear RTC RAM/Jumpers.The user guide can be downloaded from:http://support.asus.com/download/download....amp;model=A8N-ESelect version E-1911 (at the bottom of the page)Just for if you need it when someone replies in the new thread you posted.It doesn't hurt BTW to read the page I mentioned above, 1-21: Clear RTC RAM/Jumpers. Maybe that will do it to teach the mainboard who's the boss. But when you do so, follow the instructions to the letter!

StrikerHere's the latest advice-->>>I was just thinking, it's possible that that motherboard is one of the newer models that has a capacitor act as a battery for the settings, in which case removing the battery may not do the trick. If I remember correctly, there's a jumper block on the motherboard that you can use to reset the CMOS. I don't know where it'd be on that board, but you could find out in the manual I sentI looked at the MB and can NOT find these jumpersBOY wish I was a tecnicianCheers for yearsColin :)

See my post just above yours Colin.Well I can tell you where it is but I want you to read that part of the manual: it's important.

StrikerHave read 1-21 in the users manual but the diagram does NOT really point ot the jumpers although I understand what it is saying NOW have to fins and IMAGE of these jumpers because just can NOT seem them from the manual OR on the MBCheers for YearsColin :)

It's only one jumper Colin, just below the battery. Refer to the manual for the right procedure, otherwise it doesn't work.If your mainboard is different, you may have another revision of it. Then you'll have to find out which one, it's possible it is mentioned on the side of one of the PCI connectors or sometimes on the mainboard itself.And in the new thread, refer to this one: saves the posters some work and you to do some replying. :)

Striker What the manual says is--->>>Move jumper cap from pines 1-2 (default) to pins 2-3, keep the caps on pins 2-3 for 5 - 10secs then move the cap back to p;ins 1-2 Reinstall BatteryPlug in Power Cord and turn on computerHold DEL key during boot process and enter bios setup to reenter dataBUT I can NOT DO NOT see these jumpers as Manual diagram is so poorThat's why have been in Google Images to check exactly where and what they are :thumbsup: MOI a LITTLE :"> BUT :) with all this even if the Case is opened up and on kitchen tableCheers for YearsColin :">

Ok Colin. You have the machine opened on the kitchen table? Take it easy.First of all, you have to ground yourself with a wristwrap or unearth yourself again the pipes of the central heating.Now the jumper: take a look at the picture you posted earlier: http://www.thetrailingedge.com/images/prod...s-a8n-e-big.jpgYou see those 3 white PCI slots. Just below those, you'll see the battery. It should be taken out. (take care not to short circuit that battery! )When done, below the battery holder, you'll see a jumper with a cap on it. That cap shorts pins 1 and 2 in default state: the cap is at the closest position to the battery holder.Now take off that cap and move it one place lower, shorting pins 2 and 3: that's the most far position from the battery holder. Leave it there for 1 minute: take a coffee in the main time.Next, take off that cap from those pins 2 and 3 and put it back on pins 1 and two: it should be as close to the battery holder as possible again now.Next,Reinstall Battery;Plug in Power Cord and turn on computer and hold the DEL key during boot process and enter bios setup to reenter data. Just see that it boots again and the BIOS will set itself the parameters for now.Wait a moment Colin: I'm reading your post 22....

:) Aha: is the picture shown in the link in the exact same position as your main board is mounted in the machine? You see, the picture shows the board 90 degrees turned to the right, with its outside connections at the top instead of to the left...

Think you had an AHAAHA MomentThe picture to me needs rotating 90% left because the 4 white slots are on the LEFT of the BatteryBoy I am CONFUSIN' myself more and more :) So maybe explain again PLEASE PLEASE PLEASE :"> Cheers for YearsColin :">

Here's a view of the main board in the right position just like you are seeing it when you look into the computer:http://tinypic.com/view.php?pic=t8xbw5&s=3I marked the battery and the jumper.Take it from here with the boards manual and you're almost done.Do you think you can do it Colin? It's just a case of looking at the picture posted above and the board, and then following the manuals instructions on page 1-21.

See Colin, we make a technician in no time out of you! Nevertheless it's a pity it didn't work out the way we thought, so that leaves the Power Supply. I'm going to watch the other thread. Good Luck!
