A similar manual is here, but doesn't mention resetting the unit. Look on the rear for a small hole with a button behind it.

SOURCE: dell inspiron 5150 laptop, reset admin. password.

Restart your laptop and keep tapping F8 key the moment you see something on the screen. You will get a black screen with some options written in white. Select the option Safe mode and then you can create a new user with admin rights. Or else at the windows login screen press and hold ctrl and alt key and tap delete key twice and then it will take you to a login screen. Dont put any password there just hit enter. And you will be able to login with admin rights.

Thanks

Hello
IF you speak about Windows admin password
You can try these solutions

1st
Try to boot into safe mode by pressing F8, and removing/resetting your password there.

Repairing the windows with some tweaks;)
Place your Windows XP CD in your cd-rom and start your computer (it’s assumed here that your XP CD is bootable – as it should be - and that you have your bios set to boot from CD)

2. Keep your eye on the screen messages for booting to your cd Typically, it will be “Press any key to boot from cd”

3. Once you get in, the first screen will indicate that Setup is inspecting your system and loading files.

4. When you get to the Welcome to Setup screen, press ENTER to Setup Windows now

5. The Licensing Agreement comes next - Press F8 to accept it.

6. The next screen is the Setup screen which gives you the option to do a Repair.

It should read something like “If one of the following Windows XP installations is damaged, Setup can try to repair it”

Use the up and down arrow keys to select your XP installation (if you only have one, it should already be selected) and press R to begin the Repair process.

7. Let the Repair run. Setup will now check your disks and then start copying files which can take several minutes.

8. Shortly after the Copying Files stage, you will be required to reboot. (this will happen automatically – you will see a progress bar stating “Your computer will reboot in 15 seconds”

9. During the reboot, do not make the mistake of “pressing any key” to boot from the CD again! Setup will resume automatically with the standard billboard screens and you will notice Installing Windows is highlighted.

10. Keep your eye on the lower left hand side of the screen and when you see the Installing Devices progress bar, press SHIFT + F10. This is the security hole! A command console will now open up giving you the potential for wide access to your system.

11. At the prompt, type NUSRMGR.CPL and press Enter. Voila! You have just gained graphical access to your User Accounts in the Control Panel.

12. Now simply pick the account you need to change and remove or change your password as you prefer. If you want to log on without having to enter your new password, you can type control userpasswords2 at the prompt and choose to log on without being asked for password. After you’ve made your changes close the windows, exit the command box and continue on with the Repair (have your Product key handy).

13. Once the Repair is done, you will be able to log on with your new password (or without a password if you chose not to use one or if you chose not to be asked for a password). Your programs and personalized settings should remain intact.










If your talking about Bios admin pass
You can try these solutions

1st
A program like

2nd
Try taking out the CMOS battery for 5 minutes. Reinsert and restart. Enter the BIOS and reset the Time and Date.

SOURCE: i have forgot my admin and primary passwords for my dell laptop

It sounds like you are talking about the BIOS startup password and admin password. Since this was 5 years ago, there is a good chance you can open one of the doors on the bottom and find the CMOS battery. If you are lucky, it would be in a battery slot or plugged into a removable jack. If you can remove the battery, that will kill the passwords. If the battery is soldered to the main board you can still cut the wires, but then you would have to rewire the battery by soldering. I'm just answering this to make fixya points. Still don't understand why there is no time limit on these problems. The user surely does not care by now and it is likely few people will be using a 5 year old laptop unless they know a lot about laptops to begin with.

How to reset Admin password on Samsung SDR-C5300N Digitalvideo recorder


If you have forgotten your admin password on a Samsung Security DVR, most experts would suggest that you have to contact Samsung and/or send it back to Samsung to have the administrator password reset. While this is true in some cases, it is not always necessary.
Many Samsung Security DVRs have a built-in reset that will allow you to wipe the settings of the device and reset the configuration, including the administrator password. Note that if you perform one of these resets, all settings will be erased and you will have to setup the DVR again. So you should only do this as a last resort - but to reset an admin password, the last resort is the only option.
Reset Procedures for Samsung Security DVRs
There is more than one reset procedure for Samsung Security DVRs, depending on the series and model. But in total, this only amounts to a handful. Since one reset can apply to several different models, I'll provide the resets here so you can try them on yours - I won't associate any one reset with a single model because a complete list of which reset works with what model Security DVR simply doesn't exist. Some of these won't make sense based on the buttons available on your unit or your remote. In those cases, just skip that reset procedure.
If you can perform a reset (in other words, if the instructions match what you have available on your Samsung Security DVR and/or Samsung Security DVR Remote), try it, and let us know in the comments if it works and on what model. If you tell us which model Samsung Security DVR you have, along with your results of each reset procedure, we can compile a complete list of reset procedures by model so that it will be easier for those seeking this information in the future to reset their Samsung Security DVR. Also, if you have a reset that you have used and you know works, let us know and we will add it here. I will update the list of Samsung Security DVR resets/recoveries as I encounter them.
So if one of these doesn't work for you, you may want to check back occasionally. In fact, if you leave your model number in the comments and any specifics about your problem, I'll try to get that specific reset for you. For any of these comments, just use the comment section at the bottom of this page - it is checked regularly.
Samsung Security DVR Default Password
For nearly all Samsung Security DVRs, the default password is 4321. If it hasn't been changed since setup, then you can just use that to access the DVR. The default password is included in the reset procedures for completeness. If you have changed your password or access code for your Samsung Security DVR since it was setup, or if you changed it during the initial setup, use that password in place of the default password. The password will be the latest password that was set on the DVR. If no password has ever been set, then it will be the default.
Steps to Reset your Samsung Security DVR
Samsung Security DVR Reset Procedure #1
Reset the unit to factory by pressing both [MODE] and [PTZ] button for 5 seconds
Then enter the 4321.
Samsung Security DVR Reset Procedure #2
Reset the unit to factory by pressing both [MODE] and [CH2] button for 5 seconds
Then enter the 4321.
Samsung Security DVR Reset Procedure #3
This reset will work on Android based DVRs only. All steps are performed on the device itself.
Turn the device Off
Wait 2 minutes
Press and hold the following buttons
POWER,
HOME
VOLUME UP
The unit should power on. Once it does, you can release power.
Use the volume UP and Down buttons to select "Wipe/Factory Reset" from the recovery menu.
Activate the reset using the HOME button.
When the DVR goes through it's setup again, it will be at factory defaults. The password will be 4321.
Samsung Security DVR Reset Procedure #4
This reset will work on SDR models. It may also work on other models.
With just the cameras showing, press the following in quick succession using the remote:
Freeze
Alarm
Freeze
Alarm
Freeze
Menu
Enter
Make sure you press them quickly, one after the other. If it doesn't work the first time, try doing it several times. It can take many tries to get the timing right. If/when it works, you should get a screen that gives you the option to reset.
Samsung Security DVR Reset Procedure #5
This reset will work on SDR models where procedure #4 failed. It may also work on other models.
Press the DVR Button to place the system in DVR Mode
Press:
Freeze
View
Return
As with Procedure #4, you may need to press Freeze, View, and Return in in quick succession a few times to get it to work. The timing can be tricky.
Samsung Security Reset Procedure #6
Courtesy Sergio Ayala
To factory reset the SDR-B74301
Reboot the DVR
Once the DVR has rebooted, enter the following sequence on the remote:
UP, RIGHT, 5, 3, 3
You will be prompted to do a factory reset. Confirm
This has been confirmed by several people. Thank you, Sergio! If this works for you, please thank him in the comments below.
These reset procedures cover many Samsung Security DVRs, but not all.
