I have an HP DV4000 laptop with a Power-On password activated, but no password. The HP manual details how to reset CMOS, pointing to a program on their website called UNLOCK6.EXE, which is no longer available (Thanks, HP!).
Anyway, I have tried unplugging the CMOS battery, looked for a jumper or switch, etc. but no luck. It seems like the only way is to find this UNLOCK6 program to run the override password (05260) that was given to me on this laptop, so that UNLOCK6 can generate a backdoor password.

If anyone can help with a copy of this program or by generating the password and passing it along to me, it would be appreciated. Thanks!

That would be great! Thanks for the very fast reply. Too bad I didn't notice it sooner. I guess I was expecting a notice through email that there was a reply.
What would be the best way to send it to me?
Thanks

If the removing the battry does not work, then i can not see it being in CMOS. This simple code will get rid of the BIOS password, but how are you going to run it ?.
org 0x100
 remove:
  mov	 al, 0x2E
  out	 0x70, al

  mov	 al, 0xFF
  out	 0x71, al
exit:
  int	 0x20

After 3 login attempts a number code is generated. Run the utility on another machine; enter the number code, and password is generated. The password isn't stored on the cmos chip. Of course, I could be wrong, got to try until I get it.

If someone could run the utility and post the result, the code is 16220. Thanks.

From what I understand, these laptops have a CMOS chip that stores the power-on password whether the CMOS battery is installed or not. I left my CMOS battery unplugged for 28 days with no effect.

The program does not identify or erase the user-defined password, but instead identifies the specific backdoor password for that laptop serial number.
I have yet to hear back from DaleJRRocks with the application, but I hope someone will be able to provide some assistance soon.
Thanks!

1337 hack Dex :)

but how are you going to run it ?

hmmm........ put in a new cmos? :)



What exactly is the point of a BIOS password if HP has backdoor to every single one? FreeBIOS?

Best of luck. I still haven't received a response from anyone with the program after 6 weeks, so don't expect help right away, if at all.

I have the app. The only real problem is how to use it. For what it seems, everyone says that it should give you a code after the third try so you can input it in unlock6, but thats not my case. I just get a weird starlike character and don't know how to use it. Here's a picture of the error:

All, are you also using an HP DV4000? according to the documentation these are the supported systems:

HP Compaq nx7200 Notebook PC, HP Pavilion dv4000 Notebook PC, HP Pavilion dv4100 Notebook PC, HP Pavilion dv4200 Notebook PC, Compaq Presario V4000 Notebook PC, Compaq Presario V4100 Notebook PC, Compaq Presario V4200 Notebook PC

If you're not using one of those, you might need to consider another venue

Well, in my case I opened the laptop, took out the battery and left it out for over a day, with the power cord disconnected. It didn't work. I tried the unlock6 solution posted by a couple of users, but I don't get that numeric code I'm supposed to get. I only get the symbol posted in the link I gave up there.
