The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Compaq D51U Mini desktop problems anyone familier with this model in and out?

Asked by chrisfarbo in Miscellaneous Hardware, Personal Computers

Tags: d51u, compaq

I bought a refurbishd Compaq d51U Evo slim desktop for use as a car computer. I just got it last week and notices this problem since the moment I turned it on.  I am using it on a Lilliput touch screen  but  have ruled out all peripherials by hooking it up to one of the test stations at my office.

HERE IS THE DILEMMA...

when you hook the machine up with a ps2 keyboard the 3 keyboard lights just scroll back and forth much like the red bar on KIT the Knight Rider car. It is the craziest thing i have ever seen  and as a result of this  the keyboard will not work.
i am using a usb keyboard. But with it if there is a problem booting or something I have no keyboard support before windows boots up and loads the usb drivers..

I have had this problem for about a week now and Honestly it dod not bother me as the machine was working fine. but due to some hard disk error today. IT just keeps rebooting and when the startup menu comes up in XP I can not use my arrow keys  to  select a different startup option. . . Now at one point I was able to  get into the bios   but was presented with a password that i did not know.   I really do not want to lose the power on setting of the computer.   As it is now when it recieves power  it turns on. which is good   as it is mounted in the trunk of my car.    none of the  car stuff that i have hooked to it is causing this problem as it did this out of the box  hooked up on my test bench to a regular  key, mouse and monitor. .

The bios had a battery just like a normal pc would  and also a push button on the  motherboard that is labled bios.

I know i need to get into the bios and make sure that the  keyboard is enabled and this machine was setup my the company ( who is about impossible to get ahold of )  to be a car computer and run without a keyboard. So I guess it is possible that they did something to it  to make it boot with out posting a keyboard error. . .  Once agian the alternating lights  really make me wonder. .
 
 As it is now. The drive seems to be corrupted from an unrelated incident and i can not select any other startup options for the computer with out a functioning keyboard. .     please advise.  .
