<.Hola Communiters.
Tengo un problema con una Laptop , un cipote configurando un equipo nuevo le configuro la contraseña de BIOS incorrecta al sistema y creo que por la culiyera no se acuerda cual es ...
la laptop es una HP 8440p (WN014LA) ...
- Hirens no me funciono
- Quitarle la pila no funciono
- No le vi ningun Jumper como en las Pc's
- Los de soporte HP no cuentan con Contraseñas BackDoors x_x ( solo dell se q si )
- Busque algunos reseters pero no son compatibles con esta BIOS
Alguien sabe de una forma de resetear la BIOS .... gracias de antemano , Saludos ! :drinks: .>

The BIOS system can be updated with a process called 'flashing.' There are different types of flashing utilities; however, they all accomplish the same thing. Close all other programs before trying to flash the BIOS.
Winflash or HPQFlash is the most commonly used process. Download the file to the hard drive, and double-click the file to start the flash. Read and follow the instructions to complete the flash. Do not use the PC until the flash is complete and the PC has been restarted.
ROM Image is used by companies when they need to update many PCs at the same time. Download the file to the place on the network, then access the file from each PC.
ROMPaq involves restarting the PC with a bootable disc, CD, or USB key. Download the file to the hard drive, and double-click the file to create a bootable disc. Insert the bootable disk and restart the PC to flash the BIOS during the startup.

la laptop carga windows o te pide la clave para iniciar?
Using MS DOS Command:
This method works only if you have access to the system when its turned on because this method requires MS DOS. Open Command Prompt from Programs menu and provide following commands one bye one:
debug
o 70 2E
o 71 FF
quit
NOTE: The first character in the above commands is English alphabet "o" and not the number 0.
After providing the above commands, restart your system and it should reset the CMOS Settings along with the BIOS password.
If you are curious to know how it works? then let me explain the above commands:
In this method we are using the Debug tool of MS DOS. The "o" character present at first in these commands, outputs the values to IO ports. The number 70 and 71 are port numbers which are used to access CMOS memory. By providing FF value we are telling CMOS that there is an invalid checksum and it resets the CMOS settings as well as BIOS password.
