Hi all.....this is my first post. I bought a cheap ac power supply for my Dell inspiron 6000 when the original died. Yesterday, it failed. Upon inspection, I realized the power supply was shorted out. I replaced it and nothing happened...no light no sign of any power to the computer. I think I may have shorted out the computer and was hoping there is some sort of internal fuse that could be switched out. thanks for any help!
