User locked - No Admin enable - How may i fix this stuff?

Hi,

Sorry for my bad english...

This is my problem :
I have a HP Probook 5310m with Win 7 Pro 32 bits.
I've been using it for 6 months without a problem.

Yesterday, when i tried to connect (after hibernation), my password was rejected. I tried to make a second and third attempt with ware : same. I know my password, it's the same as the password of network access of my company. After that, the user was locked!
-> I don't know why my password was rejected, really don't!

Unfortunately, i did'nt enabled the Administrator account!
So now : i really don't know how to fix this huge problem (for me)!

HP told me to swith off the CMOS battery, but i'm really not sure this is a good solution.

Anybody has an idea?

Many Thanks

Vincent

If this is a company owned PC, contact your company's IT pro. If it's your windows user account login password, clearing the CMOS won't do any good. It may just make things worse.

I'm a freelance consultant.
This is my own computer, I won't call a pc contact of my customer.


HP won't help me. Microsoft won't help me.
Si i'm alone.

Thanks

Many thanks Kirsch. I'll try this.

Hi Kirsch!

I've just fixed my problem yesterday! I was missing a portable USB DVD reader.
So, i followed instructions :
+ Download the Ultimate boot CD
+ Build a boot CD/DVD from a XP computer
+ Burn the ISO
+ Start from this boot CD on my computer (the problem was, no portable DVD reader, there is no DVD reader in this thin computer)
+ As indicated, i have tried the simple program to Unlock my user (and unlock Admin too) and change the password (first try : put a password, it does not work, second try, put no password)
+ And it worked! I've put passwords for my user and Admin.


Many many thanks! Kirsch! This is incredible because it's very simple (just need the right tools...).
