The hard drive password set up in BIOS? then u need to be handy with a screw driver. First remove the CMOS battery from your computer for about an hour or more. Sometimes it may take overnight. then plug back in and then CMos forgets everything, now worries your hard drive is a stage medium so it doesn't lose any data. but you may have to reset your clock once install it back in.

I forgot my password how I can download what's up


This question needs clarification. Is "What's up" some kind of social media site? Or are you just saying, "What's up with the fact that I forgot my password and can't download stuff?".

The answer to both of these versions of your question may be:

Usually when someone forgets a password to an online account (facebook, google+, etc.) there is a link to reset your password. Easy.

If you forgot the password to your Macbook Pro then you're probably not going to get your old data back because messing with the "keychain" is not going to work. Apple may have some kind of registrar that you can contact, provided you have the required info, could help you get in but I don't know. You can reset the password though which grants you a fresh start; as if it were brand new.

On a PC there are at least two and sometimes three different places where a password can be set to secure the device; on the BIOS chip, at the Windows (or other operating system) login screen, and sometimes even on the hard drive that the system uses to boot or start-up. There are methods for bypassing each of these but, depending on the make and model of the hardware, results will vary.

BIOS chips used to have a default password set by the manufacturer. It's not so easy any more and you'll have to look up your specific BIOS to find hacks.

Windows passwords can often be bypassed by booting your machine with a bootable thumb drive or live CD/DVD. These are entire Linux operating systems on a usb drive or cd/dvd and once the machine has loaded Linux you can use it's file management software to access many of the files stored on the hard drive by MS Windows.

Lastly, passwords that are set on the hdd itself can sometimes be bypassed by tricking the hardware into thinking that the correct password has been provided. Usually this would be done by using a jumper wire (some have used a paperclip) to "jump over" the authentication section on the PCB of the HDD. This doesn't work on drives that actually encrypt the data using the password as a key and it's much more complicated than it sounds since you have to boot the pc with the electronics inside the HDD exposed and time the jump just perfectly. One wrong move could kill your hard drive.

Obviously, using a password that you won't forget is the best way to avoid losing all your stuff.

How to recover my password on my laptop


Go on line (with another computer of course) to SpotMau.com and get their boot suite program. Copy to a DVD or CD disc.
It has a startup program that bypasses your hard drive boot section and allows you to enter your hard drive boot sector. When there you can black out the original sign-in protocol (password) and it is Removed. Restart the computer and don't use a password again unless you have kids that use the system. No need for passwords if it is your computer and no one else uses it.

Need to bypass masterpass word


Which Password? Bios Password? Hard Drive Password? Windows Welcome Screen User Logon Password?

Which Operating System? Windows XP? Windows Vista? Windows 7?

OK, if you are running Windows 7, Microsoft tightenedsecurity on it so you've got to have a password reset disk which 99% of thepeople who own laptops with windows 7 fail to do. It should be one of thefirst things you do when you buy the laptop. Otherwise, you're faced withreinstalling the Operating System or possibly doing a System Recovery.

If you're on Windows XP or Vista try this:

Turn off the computer, then hit the power button to turn it back on andimmediately start hitting the F8 key repeatedly until you see the Safe Modeoption. Select SAFE MODE and let the computer boot up. When it getsto the User Login screen it will show the Administrator userid and the useridfor which you forgot the password. Sign in as the Administrator (hopefullyyou didn't put a password on it and forgot it too). Once the desktopappears it will look different, the screen will be darker and the icons bigger,but this is normal for safe mode.

Click Start/Control Panel/User Accounts
When the User Accounts screen opens, click on the userid for which you forgotthe password. Select the option to REMOVE PASSWORD.

Reboot your machine.

I locked myself out of my laptop how do i unlock it


Wow, another person locked out. LOL. Ok which password? The Bios Password? The Hard Drive Password? The Windows User Account Login Password? And for which Operating System?

If it's the hard drive password you're out of luck because that is set to keep thieves from gaining access to sensitive data. 99% of the time when you see a laptop where the user does not know the hard drive password, it's a stolen laptop.
The Bios Password and the Windows User Account Login Password can be cracked or allow you into the system, however if you're running Windows 7 and you forgot the Windows User Account Login Password, you will need the Password Reset Disk otherwise you'll have to reload your operating system.

I forgot my password and their is no other way for me to logg in so how do i reset my thinkpad to factories setting without logging in?


If it's the HDD or hard drive password unfortunately you're going to have to get another hard drive and use an operating system set-up disc to start over. This password is difficult to bypass because it its the most secure way to lock the hard drive from data thief - unless you work for Obama.

My drive became locked with a password or I forgot my hard drive password. How do I gain access to my data?

Answers from Hitachi : Unfortunately, there is no way to bypass the security password feature of Hitachi hard disk drives. If the password is not known or has been misplaced, Hitachi will not be able to assist in gaining access to the data on the drive.

My son set a hard drive password on my laptop & forgot it.


With most of the Acer's you can get by this problem by removing the cmos / bios battery for a few minutes with the battery and power adapter unplugged.

This will clear the password.

Or you could just ask your son about the password, no?

Help!


hi, If you set the hard drive password yourself and forgot it, you out of luck. I don?t know if you would be able to recover it. After a quick search on Google I found a utility called A-FF Repair Station. They support a lot of drives and license for 1 recovery will cost you about $50. I have never tried this software myself. If you didn?t set the hard drive password and the laptop still asking for it on start up, then I have a suggestion. Check the version of BIOS installed on your laptop. Three wil be some fix in the latest version like: ?Prevented the message asking for HDD password when there is a problem with the HDD?. In other words, if there is a problem with your hard drive, the laptop might ask you about the hard drive password even if you didn?t set it up. Go to Toshiba tech support website, update the BIOS on your laptop and see if you can bypass the HDD password message. According to the BIOS fix in v.1.50, the HDD password message might indicate that you have a bad hard drive. If after the BIOS update you can bypass the hard drive password message and access the data, I would recommend back it up as soon as possible. regards sreejith
