Keyboard Failure error on bootup

I have a Dimension 9150 with Windows XP Pro OS.  During usage, all at once action froze...the computer no longer responded to the keyboard. Upon rebooting, the system stopped during BIOS boot and indicated keyboard failure. Thereafter no response indicated from keyboard. We tried replacing the keyboard...problem persisted.  The solution was to unplug the power cord. That cleared something. Everything worked fine after that for about another 2 weeks. Then all at once it happened again. Same remedy worked again. That was a few days ago. But now I'm worried that something is about to quit permanently. Is it the onboard ROM? Or the main CPU?

Re: Keyboard Failure error on bootup

I've had similar problems with my 9200 and I'm pretty certain it was due to static discharge when connecting a USB device.  In one case the machine crashed.  In the other, the USB devices all stopped working.  Both times I had to pull the power cord and press the power button to get the USB devices working again.

Now I am more careful to discharge any static before inserting USB devices.

(Our humidity can get quite low this time of year ... 30% or so)

Re: Keyboard Failure error on bootup

Thanks, Peter.  I hope it's as simple as that.  It is the right time of year as you say.  My doubt stems from the fact that we were just using the computer normally when all at once it froze up.  We were not in the process of plugging in a USB device at that time.  But I suppose the static could still have an effect.  I gather that in your case it did not cause permanent damage.

 

Thanks

Re: Keyboard Failure error on bootup

In my case, everything seems to working fine.  I was pretty certain I needed a new motherboard the first time though.

Yes, your case is different.  I would run extended diagnostics particularly on the memory to make sure it is ok.

Also, check inside to make sure everything is seated properly (RAM, cables, cards). 

The fact that you have to pull the power cord to get it working again is odd.

Re: Keyboard Failure error on bootup

I read the post about static discharge, unplugged the power and plugged it back in, now it works! Mine is a Dimension 91000.  Was working online, lost my pointer, shut the system down and it restarted with the Bios scree stating Keyboard error Drive 0 not found.  Since it wouldn't recognize the keyboard, the 3rd keyboard I tried, it would not allow the F1 or F2 command.  Decided to check the posts and this was my first step beforing calling tech support.  thank you!

Re: Keyboard Failure error on bootup

Problem is usually caused by single switch bootup. Keyboard gets recognized last. Try bios fix or have USB devices, external drive, printer etc. start separately.

Re: Keyboard Failure error on bootup

The original problem occurred about 4 months ago.  I have done nothing.  The problem so far has not re-occurred.  The computer gets used about all day all weekdays.

Re: Keyboard Failure error on bootup

Wanted to follow up on this keyboard issue...

 

Had the computer tech out 3 times after the static discharge issue failed too. It was a 24 hour fix, if that. He reset the Bios and said everything was working, hours later I could hear the USB sound as the keyboard failed. We ended up replacing the motherboard on a 2 year old computer that I use for business and online shopping...seemed like a crazy idea.  Within an hour of the new motherboard install I had the same issue again! 

 

The fix? A Wireless keyboard! I actually had the first one go out in 2 weeks and trust me, I'm not much of a typist!  Replaced it and I haven't had any issues since May, I think.  Whatever was going on internally was never resolved, but the new wireless has resolved my problem.

Re: Keyboard Failure error on bootup

Well, obviously neither of us can say it's cured forever, but I will admit along with you that a few months of steady success kinda smells like long term success.
