I can get passed the screen that says enter password to open windows XP, but then goes to a screen that has three log ins one is a dummy set up second is a password which I have third is my username and I put my password In after striking enter, says opening, but then goes back the three username screen. Please let me know if I can factory restore, reset, BIOS default set, or just AM out of luck, lol It is a Dell latitude E6400, system, #5MG8BM1-2A7B, is protected by a password authentication system, thank you in advance.
