Hi there, I have bought an HP elitebook folio 1040 g2 (used) couple of weeks back from a second hand laptop shop here in Bangladesh. They say they bring these used laptops from middle east and Europe. However I bought the laptop and it was performing well till yesterday when I found out that my device manager show nothing in the list. I tried to enable the services from msconfig and even from registry editors but failed. Then I went to install the windows again but this time it's the BIOS looking for Administrator password. I tried wrong password for three times and it didn't work. Can anyone help me out of this problem.
