Hello, helpful people!

When computer is booted it stops at the following:  Hardware monitor found an error.  Enter Power Setup menu for details.  Press F1 to continue. Press F2 to enter SETUP.

I am working on a SONY motherboard with Award Medallion Bios v6.0.  All the temps seem well within the scope.  However, there is one issue that I don't know how to resolve.  The Power Fan Speed is N/A and grayed out.  I have a sneaky suspicion that herein lies my problem.  I searched the archives and the closest I came to an appropriate answer is at this link ( http://www.experts-exchange.com/Hardware/Q_20648418.html?query=hardware+monitor+found+an+error&clearTAFilter=true ), but it was not possible to use the suggested resolution, since this SONY mb only has one place to plug in a fan and that is nearest the power supply.  Just in case anyone is curious, the OS is Win ME (ugh!)

My customer would really like to avoid having to do an extra step in the boot process.  I appreciate any and all suggestions.

Appreciative as always,
Lori

Has hardware / fans / cpu / power supply been replaced or removed recently?
The rpm sensor in the fan could have gone out, try swapping out the fan.

Is there not an option to disable the bios from monitoring that power fan. If there is you can just turn it off. As long as the one that monitors the cpu fan is on everything should be fine. The only way the bios can monitor a power supply fan is if there is a sensor in the fan with a connector that can be plugged into the motherboard otherwise that sensor is useless.
Commented:
The hardware monitors do a few things. They check to make sure all temperatures are within normal operating temps. They check to make sure that fans are running correctly. They check to make sure system voltages are in the correct range.

1 You say that all temps are correct, just double check that the temperature alert range isnt set too low.

2 Check to make sure that the fans that are set to be monitored are actually plugged into the correct connector on the motherboard and if there is no sensor in the fan then you must disable the monitor that checks that fan.

3 Go into hardware monitor in the bios and check that the voltages are indeed correct and that nothing is too low or too high. If a voltage is incorrect you may need to replace the power supply.

hope this helps.

You have given me a few things to check out and I will get back tomorrow (today is a non-computer day because that ole life "thing" happens occasionally) when I am at this computer's location.  Oldgreyguy, I did, indeed, try setting the bios to default without any gain.  Been to SONY, who sends you off to another site, who sends you off to yet another site where you d/l something called BIOS agent, I think.  Again, since I am not at that location, I didn't do the d/l.

dlongan, yes, the mb and processor were removed from the OEM micro-case into a new case with new (and more powerful - moved up from 250 to a 400) power supply and with an additional case fan, because it was already demonstrating this problem.  At that time I thought it was running hot, so to protect the processor and hopefully make the hardware monitor happy, it was changed out.  Temps are good, but the hardware monitor is still dissatisfied and I suspect it is because it is not reading the power fan speed.

Nobus, I will list the details tomorrow.

Jeff, within the bios there doesn't seem to be a place to disable the monitoring.  I am mystified as to why, if it has the n/a in the bios, that the hardware monitor is still acting up.  The Award Medallion is one very, very basic bios.  It reflects the temps, but I didn't see any alert range (of course, I wasn't looking for it at that time either.) Any hint as to where I might find the temperature alert range?  The bios DOES allow you to "ignore" any of the settings, which I have done without success.  BIG QUALIFIER:  Since the power fan speed is GRAYED OUT, I can't change it out to "ignore".  Sigh.  The cpu fan is plugged into the only available place on the mb.  When you say disable the sensor, are you inferring that there is a jumper on the board to do that?  Looks to me like I am going to have to get this SONY OEM mb identified...I suspect it is an ASUS, but haven't found any manufacturer name or model # on it as yet.  Going to have to be more thorough tomorrow.

Thanks everyone for your assistance.  I will follow up once I have a chance to get back into the bios and crack the case open.  BTW, do you think a reset of the CMOS might be a solution or overkill?  Thanks.

Hi Lori,

It could be that the new fan is not compatible with the mb hardware monitoring.

What is the model # / part # of the MB?

Author

Commented:
In answer to the details found in the hardware monitor:

MB Temperature - 34c/93F
CPU Temperature - 59c/138F
CPU Fan Speed - 5696 RPM
+3.3v = +3.3v
5v = 4.8v
12v = 12.6v
-12v = -11.9v

So, you can see why I am perfectly happy with these numbers.  The only thing that seems "whacked" is that the Power Fan Speed is grayed out and marked "N/A".

I wish I could give you the info your requested, dlongan, regarding the model/part # for this machine.  It started its life as a Sony PCV-RX450, but was refurbished at some point and now has a system board that seems to want anonymity.  I have searched everywhere for what should be the model number...nada.  Well, let me correct that, nothing that appears to identify the board.  I've been to the FCC site, the Sony site, and some scary sites...none have recognized the following numbers found on the board...but maybe you will recognize something.  Anyway, the #s are: 006BFA9E, M7A380, 2A480F, and on the side of the AGP slot is 176142911 0060103 M/B.  I was hopeful, but nothing so far.

well, i'm not too happy with the 5V spec, they should be 5V; maybe there lies your problem

BTW, Something I did run across while tearing out various and sundry parts hunting for the board's identity may or may not be relevant.  I found that the ATX 12v connector from the power supply was attached in a most peculiar manner.  On the m/b there are 3 pins to which the ATX 12v connector had been connected strangely, with the two outside pins being plugged into two of the ATX 12v connector's 4 available connections.  I figured since the board didn't have any appropriate pin set-ups, this connection was unnecessary and I unplugged it.  Well, the computer was dead.  I plugged the connector back on the two pins as it was found, and PRESTO!, the computer was operating again.  A real mystery!  So, I am now wondering if this is why the hardware monitor is acting up, since the 12v connector coming off the power supply is gerry-rigged to the board.  Just a thought and wonder what you experts think!

Thanks,
Lori

in that case, why not use a normal ATX power supply?

So does the board have a non standard power connector? What does it look like exactly?

Trying to establish whether this is in fact an ATX motherboard!

Commented:
I never even thought about the possibility that it might not be an ATX board!  But then I also thought I was working with the Sony OEM board PVC-450, not an after-market replacement.  I am still trying to establish what board it is.  I will be d/loading a software program on Monday that is suppose to identify the board and will try to get the schematic on it (it was getting the schematic of the PVC-450 that clued me into the fact that it wasn't the OEM.)

I stripped down the board on Friday to establish 1) what board it was (which as you saw in my last post was not very successful) and 2) if there were any other available board connectors besides the three prong one.  In the latter case, I discovered that this was the only connection on the board, beside the CPU fan connector.  So, at present, I am going to approach this in two manners.  First I will investigate whether or not I can find a power supply with the 3 prong connector and secondly I will see if there is an adapter (which I seriously doubt) to put between the typical four female connector from the power supply and the three prong male connector on this motherboard.  I am now considering the fact that unless they want to replace the m/b, they may have to live with the inconvenience of the hardware monitor stopping their boot process.  Of course, I will also try a different power supply to see if I can correct the 5v as suggested by norbus (thank you for the suggestion) to see if that could be the issue (although that didn't seem like an unreasonable variation to me.)

Again, thank you all for your input.  I will get back to you after I have addressed your suggestions.

Appreciative as always!

is the PC bootable or not?
(Does it get to Windows)
If it does, use that ID utility or a free one that is goot is EVEREST and I see it posted everywhere here in EE

Also, if you can figure out what each of the 3 pins wants, you can manually install electrical components, like a resistor to bring down the +12v down, or i'm not sure what to do for the low +5v, but it doesn't really seem too low to me.  But, I don't know the tolerances for voltage levels.

Sorry I haven't attended this question in awhile; my mother had a heart attack and surgery so my mind was pre-occupied.  I have, however, been examining the various methods suggested and continue to be stymied.  As I had said prior, I d/loaded a program to find out what mobo I was working with and discovered that it was indeed an OEM for Sony - the ASUSTek A7S-LE Rev 1.xx.  It is a mini ATX board.  That is the sum total I have found out about this board.  I can't seem to find the schematic anywhere on the web.  I did check out my copy of Scott Mueller's Upgrading and Repairing PCs 14th edition (had forgotten I even had it) and discovered there that ARE non-standard, proprietary ATX designs, which were put out in the late 90's.  I suspect this is one of those.  I did hunt down the schematic for the ASUS A7S-VM, which was for public consumption, and found that the power fan and chasis fan on this board also required a 3 pin connector.  I have NOT been able to find an adapter for this (found an adapter that would switch out the peripheral power connector to the standard 4 pin ATX 12v connector, but nothing for a 3 pin.)

With all of that said, I suggested to the user that we simply switch out the mobo for a standard mini ATX Socket A board.  She would have none of it (sigh), so there it is...I am thinking there really isn't a good solution to this issue and she will have to continue hitting that F2 key to boot.  Your thoughts are appreciated.

Commented:
Oh, and another thing.  The way the 12v 4 pin connector is hooked up to the 3 pin connector on the mobo is as follows:  based on the user's manual for the ASUS A7S-VM, the pins on the mobo are +12v, ground, ground.  The power connector is Pin1 and Pin2 are ground and Pin3 and Pin4 are +12v.  Currently the power connector Pin 1 and Pin 3 are connected to the outside ground and the +12v on the mobo.  I wondered if that wasn't sufficient?  If maybe (please GOD!) that isn't really the issue?  I leave it to you experts.

Thanks as always,
Lori

Do you think it is possible to swap in another power supply? even if only for testing? That could help a lot.
I thought that the 4-pin power connector would be +12v, 12vground 5vground and +5v.  At least that's the way i have it for my atx power supply.  Is this 4-pin a pure white plastic or a sort of yellowish white plastic?  What are the colors of the wires?  You can look on the PSU (power supply) and it should say which colors are what voltage.  Then hook up manually (mabye even with alligator clips and electrical tape) the colored wires directly to the mobo's power connector.  Do you think you can measure the sixe of the mobo's power connector (mm) and describe the size and shape of the pins?

Well, it has been a while since I addressed this issue and I apologize to all for the delay.

I have been hunting for a power supply that would be compatible to this particular OEM motherboard.  No luck.  The party I was dealing with was unwilling to switch out the m/b with a preference to purchasing a new computer instead (go figure.)  So no resolve is available, at present, for this problem.  I was obviously leaning toward Nobus' idea that it was a power supply issue (particularly since the connections between the m/b and power supply was incorrectly matched), but since I could not find a new compatible power supply nor change out the m/b, I do not know if that would have been the fix.  However, jeff 01 and dlongan were very helpful in their suggestions which helped in weeding out other possible problems and guided my thinking process in this trouble-shooting.

I am uncertain as to how to proceed with regard to the points promised.  All of your efforts have been appreciated, but the problem remains unresolved.  I plan to close out the question, and am interested in your comments regarding dissemination of the points.  I will revisit this issue in another posting if I can get this computer from this party when they purchase their new one.  At that time, I will replace the m/b and see if the problem resolves.  If not, I will then be back to pick your marvelous brains!  Thanks!

Your thoughts, please.

I have the same issue with the same board, Sony PCV-RX450 (aka ASUS A7S-LE). I have been unsuccessful finding a BIOS upgrade so far. My question is ... Is there a two pin connector next to the CPU Fan header on the motherboard? Mine has this connector and if you have this connector, look close at the silk screen at the edge of the board next to the connector. It might say something like CPU_THERM. This connector is for a thermistor temperature sensor that some (obviously the original) heatsinks have on them. This can cause the issue that you're having. Check around and find a heatsink with one of those and your problem should go away. And by the way, your 5V line showing 4.8V is fine. If it drops below 4.6V, that's when you have to start worrying.

One more thing... you stated " I found that the ATX 12v connector from the power supply was attached in a most peculiar manner.  On the m/b there are 3 pins to which the ATX 12v connector had been connected strangely, with the two outside pins being plugged into two of the ATX 12v connector's 4 available connections. "
   Is the ATX 12V connector the one with 2 yellow lines and 2 black lines? And was it connected to the three pin connector next the 20-pin ATX power connector and IDE ports? This board does not require the 4-pin ATX power connector (P4). If this was connected to the 3-pin connector next to the 20-pin ATX power connector, that connector is for the power supply fan or case fan. Odd that the board wouldn't post with that connector off, since that's not how it should be connected.

Anywhos, here's the link I used for the manual for the Sony PCV-RX450. It has quite a bit about the system board, but not quite enough. It doesn't say anything about the CPU Thermal Sensor. You might find it useful.

Since I was unable to implement some of these very good suggestions, this question ultimately is unanswered.  I wrestled with whether or not to award points for effort and sensible suggestions or not.  I hesitated only because an accepted answer might throw fellow techies that are combing the archives a curve ball having them think that the answer accepted actually WORKED.  Nonetheless, because some of you not only gave answers that sounded as though they could have actually been the resolution if I could have found the appropriate hardware, I have decided to award points for the efforts made by you.  With that said, THIS NOTICE IS TO ALL WHO VIEW THIS QUESTION:  NO ANSWER WAS ACTUALLY PROVEN TO RESOLVE THE ISSUE STATED IN THIS QUESTION.

In appreciation of some truly excellent suggestions, I have increased the point value to 400 and I am awarding 100 points apiece to nobus, jeff01, dlongan, and sgrega1.  If I should EVER find the necessary hardware and/or have the opportunity to replace the m/b, I will return to this question, notify everyone, re-initiate the question and award the new points posted to the CORRECT answer.

Thank you

the original power supply supplied with pcv-rx450 has a 3 pin connector that conects to the "pwr fan" pin next to the atx power supply connector on the motherboard. this needs to be connected for the bios to see/monitor the pwr supply fan speed. when disconnected, there will be the hardware monitor error on boot as descreibed by flamenwind.

i encountered the same error and saw the same grayed out pwer fan monitor until i plugged in the pin. (i didnt plug it in as most boards dont manage the power supply fan speed. this board can and does manage both the cpu and power supply fan speed.). that resolved the error.

i know the question is closed, but its an FYI for those who need to know as it took me some time to find the answer and there was no reference on the internet about it.

regards,
asmd.
