I jut change m old pssword to a new password how would i know if it alread changed?


Hey, I also got locked out of my computer several days ago. I tried several free software. It took me two days and got quite messy. Unfortunately none of them work for me.

Finally I made it work with Windows Password Reset . The good news is that it works. The bad news is it is not free. You can try Windows Password Reset . It works for me.

Compaq nx6310 factory bios reset


You can try removing the CMOS battery or take it in to a good shop they have the software tweaks to do that. I know most folks are avoiding the shops for a good reason however some things just are not avoidable and by the time you learn how to crack a lost password plus purchase the software program to do it. You will already be up and running for an hours time at a shop to reset it.
This is why it is critical to make a password reset disc right away or do not use a password that you will forget over time. I use the last four of my social when I use a password who can forget that.....
Another option is to re-install and re-boot the computer to its factory settings using your restore software that came with your purchase.............John

I don't remember the Power On Password in my computer. Is there a System to remove this Power on Password?


If your system is prompting you for the Power-On Password there are a few things you can try.

First - remove the Battery and the Power Cord. Next remove the RTC battery. You can find instructions for how to remove the RTC battery from the user guide here: http://h10032.www1.hp.com/ctg/Manual/c00753552.pdf it is on Page 111. Leave all of the batteries and power off/unhooked from the computer. Next, press and hold the power button for at least 30 seconds while there are no batteries or power cables attached. Then allow the computer to sit for at least 5 minutes without the power sources. Finally - replace the RTC battery and then plug in the power cable. DO NOT PUT BACK IN THE MAIN BATTERY YET. Power the computer on and see if the password has been blanked out.

If the power reset fixes the password, then you can put back in the main battery and go about using the computer.

If the power reset does not fix the Power on Password - you will need to contact an HP authorized repair center to get it fixed. This is not a cheap option, but it may be the only way to remove the password. To get started with a repair with HP you can call: 866-234-1377.

I hope this information helps you out!

I forgot the windows password. cani get past it without rostoring the factory settings. I only know the power up and system login codes


1. See if you can log in as the Administrator, from there you will be able to reset the password via the control panel

If you cannot log in as the Administrator then download (on a another computer) "Hiren's Boot Disk". Burn it to a CD and boot up off of the Hiren's Boot Disk on your computer that is locked. Go through options and you will find several password reset tools. Use these tools to reset your password reboot the computer and you will be in.

Please rate and vote if this helps.

Power-on password forgotten! How can the computer be started?


The Power on Password is set from the BIOS configuration. Ask that person who borrowed your Compaq for the password. Once you have this password, you can enter the BIOS configuration and remove/disable this password.
Depending how old you Compaq is, removing the BIOS battery and main battery for 15+ mins may remove this password and restore the BIOS to the factory default (insert both batteries again) and configure the BIOS Date and Time etc.
BUT if the the password is stored on an EEPROM chip then removing will not fix this problem. There are no backdoor passwords available.

Power on password problem


there are several ways on which you can reset the cmos in your pc, most common ways are removing the battery (like what you did) or doing a short circuit on the battery or reset pins. However there are some manufacturers now that use a different method, I had a dell PC before where the reset pins are already shorted, to reset it, I had to remove the jumper, power the device for 10sec, power it off then put the jumper back, kinda odd but I guess that how dell wants it, you can try that method as well. there are some that requires a key or before it could be reset like what I heard on some HP brand computers, the use has to call HP, then they ask for the serial or something then give ot generate a key. The best advise is to consult the documentation or vendor of your laptop for details on how to get your reset your laptop.

cheers,
