Compaq presario c502us laptop how to enable the administrator account in the system recovery options

You'd be better ordering the disc from compaq/hp.

Here is your only option besides trying to restore, or using the recovery partition to the way it was from the factory. If you do have to recover make sure you back up all important data to a thumb drive first. And for future reference always have two administrator accounts password protected.
There are numerous hacks that can be used, and I would advise people against
them. Instead, stick with XP and work through the problem. To restate the
problem, if the admin account has been disabled (to the best of my knowledge
there is no way to delete it completely!) you will come to the windows login
without a login name. You can press ctrl+alt+delete twice to pull-up a
log-in screen and when you type in "administrator" and enter your password
(if you have one!) it will say "Your account has been disabled. Please
contact your systems administrator." Obviously you can't go much further
with this. Instead, re-start your machine and keep hitting F8 and enter safe
mode with command prompt. You should be able to hit ctrl+alt+delete twice to
pull up a log-in screen again and re-enter administrator and whatever
password you may have. That will take you to a command prompt "C:\ documents
and settings/administrator." Now you are in business. Simply type "control"
at the prompt and press enter. This should bring up a message that allows
you to enter Windows recovery function, and it will also open the control
panel. Click on Administrative Tools and then Local Security Policies to
bring up the settings. On the left side bar you can select Local Policies
and then Security Options and Enable the Administrator Account the same way
you may have disabled it.
Thank you and good luck,

The best option is to contact HP they will direclty provide you with the steps..
First contact them and then rate me if I was correct or not...
I am sure they have the steps..

Unmountable boot volume means your harddrive has gone out.You will have to get a new one and load your os again.Sorry:-(

You need to repair your operating system (OS), using your OS installation CD.
OS repair wont loose your data, it will simply repair and correct your errors

The Center Pin Is Always Positive

presario c700 is coming with vista not with xp. so how u got xp recovery disc?? check the bios for enabling (for vista) or disabling (for xp) option for sata drive

The windows logon password?
Restart the computer and when you see te Compaq logo press F8 and keep [ressing it until you see a menu. Select Safe mode. If the Administrator account is enabled, at the logon window select Administrator (hopefully no password required). Once you're in right click on the My Computer icon and select manage. Now double click on Local Users and Groups select Users and on the right panel right click on your username and then select Set Password. Proceed clicking Ok and set a new password.

You need to tweak your power options to get this functionality back, these options are found in the control panel under power options.

command prompt: click on start>run then type in "cmd"

admin accout: click on start>control panel>administrator accout
