This is the SpeedStep technology feature of your processor. It will speed back up to 1.7 GHz when it is needed. Slowing down the processor saves battery life.

SOURCE: Dell Latitude D800 Boot Problem
Did the diagnostics pass the RAM and the hard drive.
You should check the BIOS settings to see if the hard disk is detected, if possible reset the BIOS back to the default settings and see if the computer boots up.
If not :-
Then it appears that the operating system is either corrupted or system files were deleted or infected with viruses.
Your only option is to do a operating system repair or a complete new install of Windows.
I recommend you do a new install.

Ok, this is a misworded error message on dells end. this laptop does not have a modular bay instead it has a locked in disc drive. Based on what i have seen on other dell laptops i would have to say the cd drive is going bad. To test this try removing the cd drive. Power the laptop on and push the eject button then power the laptop off. Flip the laptop overand there will be a screw to hold the drive in, this screw will be close to the center and will be the only screw in a square hole, remove this screw. Now if you followed my directions, you should have the drive out. Pull the tray out as far as it will go then grab the two sides closest to the laptop and gently pull it out. If you are having problems you can stick a flat screw driver in the square hole and push the piece of metel to the side to remove.
Now power the laptop on it may say something about there not being a cd drive(optical drive) if it does not say: "the device in the system modular bay cannot be identified" then you need to replace to CD drive.

I had the same problem. I took out the optical drive, and powered it on, and it worked. I may have to purchase a new optical drive?

Remove BIOS battery. Short BIOS jumper or leave the battery out for a long time(Over night,maybe) This should default the BIOS to having no pass word present. If that doesn't work then evidently Dell has one within the BIOS . Just ask them.
