Bios locked and not get full display

Hi,
If you have a BIOS password issue, you can check the the picture below: .

You need to remove the battery that looks like on the left of the picture to reset the BIOS password.

Thank you for using Fixya, your recommendation is highly appreciated for the free support.

Sounds like a loose connection if it used to work fine and problem starts after after you taken it apart.

The bad news is you will likely need a motherboard repair. The reason why they suggest to have your laptop plugged in when doing a flash is that you could really damage the BIOS chip itself. Contact HP- at this point, it will likely need repair.

You need to remove the bios battery to reset the bios to defaults. With as complicated as some laptops are to take disassemble I recommend letting a professional in your local area do it. It should not be more than 20 or 30$

Have you changed the resolution?
Go to control panel, display, settings, and make sure the resolution is set to more. Click on the advanced button and choose the tab for graphics or the graphics controller, choose properties, and adjust the screen area.

If that doesn't do it, is there a possibility that the wrong driver has been installed. You can check the original product specs at hp.
