Unfortunately, no such list or facility exist. Your Dell computer came with a warranty for either onsite repair or depot repair. The purchased warranty also requires that some troubleshooting steps be taken with a Dell Technical Support representative, prior to setting up warranty service. You can also post on the Laptop General Hardware Forum board and one of our community members can assist you in troubleshooting.
I'm in WA and have some hardware problem in my dell laptop. I want to find the official repair center near me.  It's hard to find the place in the internet. Could anyone give me the official repair center address list in WA? Thanks.
