"Tyrantmizar,"
As my training is in the Electronics field and have been involved in that for about 50 years or more, maybe I can give you some suggestions on where to dump it. NO, just kidding, could your battery have died? Will it not respond at all? Will it POST? (That is Pre-Operating System Test before the screen comes up with the instructions on how to enter the SetUp program.) Maybe it is just having problems recognizing the H/D? Give us some clues, Man, we would like to assist you.
