The reason you are getting the problem is because you don't have a Dell Wireless 1704 card. You actually have a Dell Wireless 1705 card which is why I asked for the hardware ID to check against. Install this driver: [URL]
Good morning, My laptop is not functioning correctly, I am getting the following results when running diagnostic tests:  Error code: 2000: 01 42 Validation code: 100554 There is no boot device detected and the media checks fail.  As a result I have purchased a new hard drive (reseating it did not solve the problem). What is my next step? I do not have discs to reload the OS.  Any help would be appreciated!  Thank you.
