HP Envy 15 BIOS chip issue

[waleedz17]

My HP Envy 15 showed the 3F0 error during boot. I tried all possible troubleshootings that I found online to no fruition.

I handed over the laptop to a local technician who has told me that the BIOS chip is not working. He says there is a 90% chance that the repair will work. If it does not, the motherboard will have to be replaced.

Please guide if I should go ahead with the repair or if what he's saying is accurate.

Is there any other method to fix this problem??

You do not give us the model number. And you do not tell us what repair the technician proposes to do. Replacing a BIOS chip is major surgery and not very many repair shops in the USA are set up to do that. Also if it were the BIOS chip the system would not boot to the point of giving you the 3F0 error which is usually the hard drive not the BIOS chip. I am skeptical in other words.

Thanks for the reply. The model number is HP ENVY 15-j002ex.

He said that he attached a perfectly working hard drive to the notebook and the same error appeared.

Could it be the connecter cable? If so, how can I identify that it is infact the case?

[Huffer]

Yes it might be the adapter cable and to check that you would need another known good one. It is many times more likely to be a bad motherboard than a bad BIOS chip or a bad cable if its true that they system does not recognize a known good hard drive. The tech knows you will wind up replacing the motherboard (assuming you do not choose to just buy a new laptop) and he wants to charge you for two procedures. Ask him to explain what makes him think the BIOS chip is bad. As I said if that is the case the laptop generally will not POST and yours is POSTing because it gets to the 3F0 error screen.

I talked with the technician again and he is saying that the computer is unable to access the BIOS menu.

He says he will copy the programming of the BIOS chip somewhere and then reprogram the chip.

Is this possible??

[Huffer]

Theoretically yes if he has the right equipment. It is rarely done in the USA because labor costs generally make it cheaper to just buy a new motherboard.

I brought back the computer from the technician and now there is a new problem. The attached error is shown.

[Huffer]

What happens if you hit enter. He probably removed power to the motherboard and it reset the BIOS settings. 

[waleedz17]

The laptop restarts after hitting enter and a blank/black screen shows up and there is no progress after that.
