I called my supplier and they shipped me out a new power supply. It got here today. I immediately tore open the package and plugged it in to make sure it worked. It was fine.
A couple hours later, I checked it again...and this time the error message about it not being plugged in appeared. I unplugged it, checked all the connections, and plugged it back in. This time, the screen was totally dead.
I'm almost in tears. I'll call the supplier in the morning, but I can't imagine it won't take weeks for me to ship it back to them so they can fix it and then have it returned.
I looked into what it would cost to purchase a refurbished one. Waaaay out of my price range.
I don't know what I'm looking for by posting here. Sympathy, I guess. I miss not feeling like a walking zombie.
