Dell D610 will not boot to hard disc

The time it takes for a Dell Latitude E6400 to complete a diagnostic boot can vary depending on several factors, including the specific hardware configuration of the computer, the number of diagnostic tests that are run, and the condition of the hardware.
Typically, a diagnostic boot on a Dell Latitude E6400 can take anywhere from 5 to 20 minutes, depending on the specific model and the complexity of the diagnostic tests.
The diagnostic boot process on the Dell Latitude E6400 starts with a pre-boot diagnostic test that checks the basic functionality of the computer's hardware, including the memory, hard drive, and keyboard. This test typically takes only a few minutes to complete.
After that, the system will run a more extensive set of diagnostic tests which include PSA (Pre-boot System Assessment) and ePSA (Enhanced Pre-boot System Assessment) . These tests take longer to complete and check the more in-depth hardware such as the system board, processor, and other internal components.
You can also run an extended diagnostic test that checks all the hardware components of the computer, including the memory, hard drive, and other internal components. This test takes longer to complete and is typically used when the computer is experiencing hardware-related issues.
Please note that the diagnostic boot process can take longer if the computer is experiencing hardware-related issues, and if the computer fails the diagnostic tests, it will stop the boot process and show an error message.

Using the F12 Diagnostics
* Reboot and press F12 to enter the Boot Menu
* When the boot device list appears, highlight Diagnostics and press Enter
* The computer begins to run the Pre-boot System Assessment, a series of embedded diagnostics that perform initial testing on your system board, keyboard, hard drive, and display
* If the Pre-boot System Assessment completes successfully, you receive the message Booting Dell Diagnostic Utility Partition
* Press any key to continue
* Press any key to start the Dell Diagnostics from the Diagnostics utility partition on your hard drive
* After the Dell Diagnostics loads and the Main Menu screen appears, click the button for the option you want to run -
Express Test = Performs a quick test of devices. The test typically takes 10 to 20 minutes and requires no interaction on your part
Extended Test = Performs a thorough check of devices. The test typically takes 1 hour or more and requires you to answer questions periodically
Custom Test = Tests a specific device. You can customize the tests to be run
Symptom Tree = Allows you to select tests based on a symptom of the problem you are experiencing
* When you have finished running a test, close the screen to return to the Main Menu screen. To exit the Dell Diagnostics and reboot the computer, close the Main Menu screen

You should try to know what is wrong and especialy if your 2.5" hard drive is, then download and burn an operating system with other computer and use it to instal new.

This is a freebie
The system is not booting to the hard drive, the #9 indicator is an indication that the number lock is enabled.
Try holding the Fn key while powering on the system, see if diagnostics run (The works on newer Dells, not sure about the D610) If you don't have that function, if you have the resource cd, try and boot to it and run diagnostics.
Generally, the issue you describe is a problem with the hard drive, if it passes diagnostics, then see if you can repair the windows install booting to the XP Cd

That message usually appears when the hard drive has crashed or if you're lucky you've got a cdrom or dvd in the computer and the boot order is messed up. 9 out of 10 though it means the hard drive has crashed though :(

Do you have any important files on the hard drive?

Hi,

DELL Laptops usually have a bulit in self test.
You can enter it either by pressing F10 key at boot time and then go down to "Boot to utility partition" or "Hardware test".
If there is no such menu, you can still find your "Drivers and Utilites" disc. Put it in your optical drive and boot from it. You will be asked for starting tests by pressin Keys "1" or "2" or so. Once you booted into the main menu choose "Test System" and finally "Run tests". Optionally, you could specify the hardware part that you want to diag, but harddrives take most of the time, all other components are tested within a few seconds. Thus you can take the full diag as well.

Try re-installing windows operating system again by booting from cd and if it stops again, you need to replace the hard drive.

It sounds like the virus did something to the boot sector of your hard drive. Once you have been infected with a virus, it's usually too late to install an anti-virus program to clean your computer.

If you have your Windows installation CDs or a recovery disc, you could attach your hard drive as a second drive to a computer that already has a good anti-virus program installed, and wipe the hard drive and reinstall Windows.

Good luck!

you might have jarred the memory loose. take it to a local technician to have them check it out.

Try to boot from the Resource CD by selecting the <F12> key and select boot from CD/DVD drive. If you tried to run the "Diagnostics" option from the <F12> boot menu and it went to command prompt, there might be an issue with your hard drive or the "Diagnostics" partition is corrupted or missing. If all tests pass using the Resource CD, then your OS is probably hosed. As for the 9 LED light, that just indicates that your numeric keypad is enabled.
