The only way to clear a BIOS password is to open the case and look for the CMOS battery on the motherboard. Small battery looks like a watch battery. Take it out, wait five minutes, put it back in and start. Password will be cleared.

I cant remember my login password and f8 does not work in safe mode still asking the password


Once you assign a password to your HP computer's BIOS configuration utility, you will need to enter that password every time you attempt to access the BIOS.
If you forget this password, don't fret there is still a way to unlock your BIOS without actually knowing the original user defined password.
This involves using a "backdoor" password, which is something that is installed onto your BIOS at the factory level that never changes.

Turn on your HP computer.
Press "F2" to load your HP BIOS access screen.
A password prompt will load on your monitor.
Type "merlin" into the password field (with no quotes) and hit your "Enter" keyboard key to unlock your HP BIOS password.

Acer Aspire85 wont boot anything


You need to get into Bios Setup when the pc first starts.

I am not sure but I think the F2 key lets you into Bios Setup

The primary boot device needs to be the Cdrom drive.

The starting order for the pc needs to be set to
1st Cdrom
2nd HDD

You should then be able to install Vista.

Laptop HDD is now locked


The hard drive password is setup from the BIOS configuration.
To remove the password you need to go into the BIOS configuration and you need to get the password from your brother.
There are no backdoor passwords, if you cannot get the password or guess the password then you need a new hard disk. If he has also set a BIOS password (you need this to get into the BIOS configuration), otherwise he owes you a new computer.

How do i bypass the primary drive lock password


On the mainboard near the coin battery you'll find a jumper. take it off and reboot. Replace it and reboot again. that works sometimes. If not you can go to the motherboards' BIOS like Phoenix and they have backdoors built in. Read on:
Backdoor passwords Many BIOS manufacturers have provided backdoor passwords that can be used to access the BIOS setup in the event you have lost your password. These passwords are case sensitive, so you may wish to try a variety of combinations. Keep in mind that the key associated to "_" in the US keyboard corresponds to "?" in some European keyboards. Laptops typically have better BIOS security than desktop systems, and we are not aware of any backdoor passwords that will work with name brand laptops.
WARNING: Some BIOS configurations will lock you out of the system completely if you type in an incorrect password more than 3 times. Read your manufacturers documentation for the BIOS setting before you begin typing in passwords
Award BIOS backdoor passwords:

AMI BIOS backdoor passwords:

PHOENIX BIOS backdoor passwords:

Good luck...hope this helps...

I forgot my administrator password


Are you talking about the administrator password in windows? If so it doesn't have to do anything with bios and you have reset the motherboard to factory settings.

To be able to install window xp or vista you will need to set the settings in bios to boot from CD,A,C in that sort of order so that the cd rom will boot. Place in the CD into your primary cd rom/dvd rom and exit saving changes to bios. When the computer goes to start up it will ask you to press any key to continue into installing windows. Follow all the prompts and you can select to install a new version without saving anything.

See how you go, I will be on live Chat on saturday GMT 10.00 time 8p,m onwards.
