Re: Slow BIOS menu display
After a long trial and error I finally found the error.
In simple the error was due to a no original AC Adapter. I don't why but buying the original HP AC adapter the problem was solved.
The history was the following:
During a electrical surge in my house my AC adapter was burnt.
Then I went to a near to my house computer store and I bought an alternative AC adapter costing near 50% less. The same current, power and everything visible on the label adapter was identical to the original HP adapter.
Then I went back to my house and installed the new AC adapter. Since this moment the laptop begun to run slowly. In that moment I thought that the electrical surge damaged the hard disk or any other hardware piece. Moreover each time I turned on the laptop I received an disk error. I sent the laptop 3 times to the best HP authorized technical store. Finally a old technician got the problem: the fake adapter was delivering a different current. (The label shown another current value)
CONCLUSION: buy original HP AC adapters only even thought all alternative (no HP brand) AC adapters could work.
