514-CPU or Chassis fan not detected

IDoAsIPlease

Hi guys,
We have a CompCRAP Presario... oops Compaq

Anyway, it runs XP Pro, it has been updated and all virus and all scans etc have been run.

We installed a CPU and case fan in the CORRECT connections on the motherboard, and now we are getting an error where we need to hit F1 in order for window XP Pro to load.

ERROR:
"514-CPU or Chassis fan not detected. Initializing Inter(R) Boot agent Version 4.0.19 PXE 2.1 Build 083 (WFM 2.0), RPL V2.73 MUST HIT F1"

Any ideas?

Any help will be GREATLY appreciated!

Thank you in advance

If you are absolutely sure that all your fans are functioning properly, go into the BIOS, turn off fan monitoring, and see if the error disappears. If it does, it might be time to take a very close look at all of your fans. Are they connected with a dinky little three-pin connector going straight to the MB, or to a big four-pin molex connector (like that used by the HD and cdrom)?

It could also be an indication that the fan(s) are dying and can't rotate at the RPM's needed to be detected by the BIOS. What do your temperatures look like?

ALL of this happens right @ boot up, so I do not think it would be a temp issue... OR WAIT!!! If the pc shuts off after awhile by itself, it may be hmmmm, what ya think?

where do I go to look for the Temps?

How do I go into the BIOS to turn off fan monitoring?

Perhaps compaq requires a fan with a proprietary connector or fan in order to detect it in the bios.

From this page:

Compaq Presario - Press Alt + Ctrl + Esc at boot when you see the "Compaq" log in big letters

Note: Different models may vary. Which model do you have?

ise had Biostar boards that require the CPU fan to be plugged into CPU_FAN_0 or what ever or the machine just turns off like hes describing. i bet its the same deal, there are more than 1 3 pin fan connectors, or the new fan uses a molex connector.

It is a Presario 5000 model.

I will look @ that..

thx guys

PLEASE DO NOT end this post, I will say when I have fixed this problem..

Have no fear.

The only forum where threads are closed as a general rule is the Spyware/Virus/Trojan Discussion Forum. We'd prefer that you not close this thread, either, even once the problem is resolved. Someone may come along at a later time with something helpful to add.

Try F10.

If that doesn't work then there is the old trick of tapping keys as fast as possible, the more frantic the better. If you're lucky you'll get the right one. If that fails, it sometimes gives you a keyboard "key stuck" notice and then offers you a choice of either continuing or entering the BIOS.

Hi,

the solution is quiet simple. You will need to do some wiring. E-mail me!

Did this resolve the error? I have the same situation.

I was having this issue on a machine of which the chassis fan was removed and the POST began giving the error message described above.

I was able to get the system to boot without POST errors by using a spare jumper and putting it on pins 1 & 2 on the motherboard fan input itself. Looking at the original fan wires they were jumpered together anyways on the clip, so it should not hurt anything by jumpering the board directly.

Thanks for offering help. Better than an e-mail response, please poster HERE! E-mail - helps one person; posting here helps many.

IDo~, before you try solutions, let's first find out if there is a physical hardware problem - fans not spinning. Pull the side panel off of the computer case and observe all fans. If you have a dead or dying fan, your FIRST order of maintenance is to replace it, or clean it if it is clogged with dust and lint. You don't want to bypass fan warnings if there is indeed a fan problem.

Even easier solution:
But first, DO ensure that the CPU fan works. In my case, I was replacing a noisy fan and observed that the new fan did indeed work, but had to press F1 at each startup. Yes, the old fan was wired with pins 1 & 2 tied together.
My solution: Plug the new CPU fan into the chassis fan header, and use a jumper (I took one from an old hard drive) across pins 1 & 2 of the CPU fan header. The fan speed still varies as before, and speeds up when the CPU utilization goes up.
I know this is almost a year after the last post, but hope it helps someone in the future.

While I admit that I almost didn't read this thread because it starts out deriding Compaq (I'm a seasoned professional and have an entirely different experience), I read through because I've had a similar issue with my chassis fan: replaced, I received "chassis fan not detected"...and was forced to press F1 to continue. Since my BIOS doesn't allow skipping this message--and it's possible it could be reset while I'm away--another solution was required. I can't have machines stopping in POST.

Following is an image showing the original chassis fan for my Compaq Evo W4000 Professional Workstation:




The red jumper wire shown to the left of the 3-pin connector (alignment guides are on reverse) clearly shorts the leftmost pins, and is described by other comments in this topic. If for any reason this image disappears in the future, the fan markings are:

ADDA
DC Brushless
Model AD0912US-A70GL
DC 12V 252711-001
0.30 A 29175 (TC)
ZP ADDA CORP. HM

...and the fan was whisper quiet and lasted for well over 5 years of high use; I didn't even know it was failing until I accidentally hit the case one day and it started buzzing. The wiring colors--where the largest surface of the connector is facing us, the alignment tabs are on the reverse, and the wires exit on top--is, from left to right, red (jumper), red (jumper + fan), black (fan).

Cheers, folks--and please--most manufacturers are trying to stay in business, and we all have differing opinions and experiences with our hardware. Product lines and support cater to classes. Business machines are different than home machines, as are our relative experience levels. My professional experience with business products runs counter to many home experiences, and there's a reason why the typical business product costs more--but not always, e.g., Symantec Antivirus (business) as compared with Norton Antivirus (home). Same company, but I consider the former to be far superior because it's less expensive, easier to use, and has a much cleaner implementation. Do you have a home business, even if it's just a hobby? You qualify.

That said, if you're having trouble with a manufacturer's product, consider where you're buying; it's frequently not the company as much as it's the product's target audience. To really sink teeth into this, consider: In the last 18 months, I learned firsthand from a company (name omitted) that they couldn't care less about the problems home users were experiencing with their ubiquitous machine--they make their money from (high-end, and) business machines, and that's that. Griping about "big business" outside of a PR fiasco affecting their business reputation isn't going to change anything either. If you want business stability and quality, that's the environment at the plate.

N.B.: I don't work for Compaq--though I do resell Symantec--and I defend Compaq because I've had very few problems with thousands of Compaq-branded machines.
