Dell OPTIPLEX GX620 Keyboard Failure

January 6, 2010 at 18:34:32
Specs: Windows XP Pro SP3
During POST I get error message: Keyboard Failure. Strike F1 to continue, F2 to run setup utility. This is both inane and funny at the same time, yet frustrating. I have tried all of the obvious solutions (try another keyboard, try kb on another PC, etc.). There are no PS/2 ports on this PC. I have tried resetting the BIOS to default settings according to documentation at mfr. Website. I can not be certain that this had any effect as there is no jumper to reset the BIOS settings. The motherboard has only two jumpers labeled RTCRST (real time clock reset) and PSWD (password reset).

Thanks in advance for any help that may be provided.

Did the OPTIPLEX also emitted a series of beeps during start-up? If you also heard a burst of three beeps followed by two beeps followed by four beeps, it means Keyboard Controller test failure. In layman term, the keyboard controller chip on the motherboard has failed.

You have three options:

1. Solder out the failed motherboard chip.
2, Replace motherboard.
2. Buy new computer.

There are no error beeps on startup. the computer simply stops at "Keyboard failure".

Some motherboards have only TWO pins that are used to clear the CMOS. Therefore no jumper is normally installed. If your board is one such board you can simply temporarily short those two pins with a screw driver to clear the CMOS. Be sure to perform that operation with power unplugged.

Look for two bare pins labeled clrcmos or similar.

Did some incident lead up to this occurrence?

Resetting to BIOS defaults on this computer involves removing the jumper from PSWD and momentarily placing it on RTCRST. Sorry, but I think I made an erroneous statement in my original post. The BIOS reset worked in that the system reconfigured IDE on subsequent restart but still getting keyboard failure error. I am thinking that by default on this system, USB Legacy support is not enabled.

Sorry, I didn't completely answer the last post. As I stated in original post, the MB has only two sets of pins. The PSWD is jumped the RTCRST pins are bare. This is the normal configuration for this PC. No incident leading to this failure. This computer was just purchased re-certified from a major online retailer of computers (whom I am sure we are all familiar with).

If you have no PS/2 ports then USB support must be enabled by default as that is the only type of keyboard available.

Now that you mentioned your just purchased the computer as re-certified you must either have a return option of at least some warranty.

IMO it is OK to say where you bought it. Actually may be helpful to someone in the future.

Have you tried the keyboard in a different USB port?

"If you have no PS/2 ports then USB support must be enabled by default as that is the only type of keyboard available."

This would seem logical, but then again, the error message is not logical.

I have already obtained an RA#, but was hoping to save myself the trouble of shipping it back and waiting for replacement (though, that is what I may end up doing).

The retailer is I have been making purchases from them for approx. 12 years (over 200 transactions for myself and on behalf of my employers). Always been happy with their merchandise and did not see any point in unnecessarily disparaging them.

I did not list it in original post, but yes i have tried all USB ports.

Try in the future. Compare prices. The service at newegg is superior.

The normal re-furbish may only include replacing missing items and giving it a quick look over. I think that is the way everywhere so it isn't necessarily a black mark against tiger.

If the original purchaser doesn't disclose the condition it may not be discovered. Frankly, I don't think tiger or any other vendor wants to invest the time to thoroughly check out a product like a computer. Better to let the customer do that for them.

I wouldn't buy a product like that for those reasons, but that is just me.

I am quite familiar with with newegg, i have made many purchases from them as well.

Compare prices? I have and that is why I ordered from tigerdirect.

"The normal re-furbish may only include replacing missing items and giving it a quick look over. I think that is the way everywhere so it isn't necessarily a black mark against tiger."

This is not nearly my first experience with a re-certified (not re-furbished) Computer. I have purchased a total of 9, 2 were for my own projects. Some had very minor and easily remedied problems. This one is just crazy.

Insofar as the re-certification process, I agree that all of these machines can not be thoroughly inspected. However, they come with a clean install, of the OS.
So, there must be at least a cursory check on these systems. If the OS is installed, doesn't mean that a keyboard would have been used ( in this system the keyboard is the first device configured, can't do anything without it.). If so, what could have happened to the keyboard controller or MB from the time the OS was installed and I got the machine.

This PC is not intended to be my primary (I would never buy used for that purpose). Rather I purchase these for specific projects.

Anyway, at this point i will just send the PC back and try another.

I will end this post, but first thank you very much for your efforts. I really do appreciate your time and effort!

At least at this sight I was actually able to find someone who knew what they were talking about (OtheHill), unlike the other forums i have tried.

Thanks again and happy New Year to all!

OK then same to you.

I might add that systems are not newegg's strength. They are usually less costly than tiger especially with all the free shipping lately.
