Specify tag number, and windows version used. But, usually is the chipset drivers. Another common issue is the external card reader not being installed by default inside windows.

one of the devices connected to your MB isn't connected properly.
try to remove them and then to install it again

remove any cd or floppy disks from the pc...reboot ..if the black screen reaper with the same message about the missing file ..you have to insert the windows instalation cd ...and repair..the missing file

It sounds like either the battery or the drive (floppy or CD-ROM) is not seated correctly. Try removing each of them and inserting them again.

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.

The modular bay refers to the optical drive (CD drive). There is a small screw holding it, I've had machines at my shop that this screw fallen out and the drive wasn't making a good connection. Be sure that the drive hasn't slid out a bit. Take it out clean the connection and put it back, making sure it's seated properly. Try this, then let me know, and we'll go from there.

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?

Power off even it it takes a battery removal. Now check modular bays and remove then fully insert each device and retry power up. If same results, try repeating above with one of the modular devices removed.
