I have this very very hard problem. I've never encountered this kind of problem. I'm fixing computers for almost 7 years.
But this laptop of mine surprises me. Here it goes... my laptop is protected by Supervisor password.I power off my laptop and take a nap for 2 hours. When I turned on my laptop I tried to input my supervisor password and it states that my password is incorrect. I tried it for 3 times a small box appeared containing a System Error Code and Service tag. I tried to call Dell and they provided my the backdoor password unfortunately the password doesn't work. They've told me to replace my motherboard which cost more than 100 bucks.
What is the root cause of this?
