This notebook Compaq Presario V3000 requires a password to enter BIOS setup but we don't have the password as it was bought second hand.

Where to locate the button battery so that we can reset the CMOS? Is there any other easy way to go about? I've downloaded the CMOSPWD (http://www.cgsecurity.org/wiki/CmosPwd) but it doesn't work.

Can someone help?

I did removed the 'RTC' battery for about 19 minutes with both the laptop battery and power cord out but it doesn't help to clear the password.

Is that the only battery or there's some others hidden somewhere?

Did you remove the laptop battery?

Yes. I did.

I'm now trying to perform a fresh install of XP Home but the installation halted because it says that "Setup did not find any hard disk drive installed in your computer"

I thin it may be the SATA driver that's required. Where can I get the SATA driver? HP download site for this particular model has no such driver available.

Try these standard drivers (http://rapidshare.com/files/46694067/Intel_Driver.zip.html)

Then slipstream it using something such as nlite.

What you may also need to do to clear the cmos is find the cmos jumper, with 3 pins and a jumper across 2 of them(i.e 1 and 2) move it to another position such as (2, 3) and then unplug all batteries then wait 30 minutes.

Tried a installl CD with SATA driver slipstreamed (not for HP notebooks) but still could not get it to recognise the HDD.

I really need to get into the CMOS to see what's wrong. I've unplugged both the RTC batter, laptop power battery and the Power cord from the adapter but still couldn't remove the password. Where can I find the reset pins for this model? I'm getting mad with this machine. :badpc::badpc:

You need to change the sata mode in the BIOS for the install.
Why can't you just ask the person you bought it from for the password?

Do you think that by flashing the BIOS update will reset the password?

It might on a normal system but I don't know about laptop.

Since they are designed to be more secure the password may not go away



Did any other settings clear when you removed the BIOS battery? Maybe you just need to leave it longer.. overnight perhaps?

Have you tried BNTBTC? might be something in there you can use...


Although if the procedure outlined in the manual doesn't work...

1.2Resetting the Computer
If the computer you are servicing has an unknown password, follow these steps to clear the password. These steps also clearCMOS:1.Prepare the computer for disassembly (refer to Section 5.3, “Preparing the Computer for Disassembly,” for more information).2.Remove the real-time clock (RTC) battery (refer toSection 5.5, “RTC Battery,” for more information).3.Wait approximately 5 minutes.4.Replace the RTC battery and reassemble the computer.5.Connect AC power to the computer. Do not reinsert any batteries at this time.6.Turn on the computer.All passwords and all CMOS settings have been cleared.

I left it overnight last night - nothing happens.

I really don't know, you'd think that would work - hey you'd think that would work even after 5 minutes like it says in the manual

Maybe try HP tech support directly?

Did you give the BIOS update idea a try?

Unfortunately, BIOS update can only be done in Windows environment, no DOS update utility available for this laptop.

Will try to phone HP's tech support but according to forums comments, the only way is to send it to them to unlock it and can expect a huge amount of service charges.

A friend of mine unlocked a Toshiba laptop using a specially-wired parallel plug attached to the parallel port, but his is an older model...
