It is a pleasure to participate in this forum that helped me a lot because almost all the doubts that had already been very well answered!
I have a very strange problem.
I bought an HP Pavilion 1220us completely disassembled for $ 70.00.
Once assembled i found two problems that is kind of a stripe that appears at the bottom of the LCD and HD with badblocks.
The LCD does not hurt so I went to HD and bought a Samsung HM500JI
That's where the problem.
The BIOS does not dedecta HD, I tested in the PC and the Compaq C500, okay formatting and installing windows without any problems.
Interestingly, the 1220us works perfectly with the C500 HD is a Seagate Momentus 5400.3
And then, what do you think is happening?
Thank you all for your help!!!
