Bios reset for HP OmniBook XE3-L

By jimmy ·
I have 4 HP OmniBook XE3L laptops that have had BIOS passwords set, (which no one knows who set them or what they are set to) and they are set with the Hard Drives disabled, so they are useless. I am needing to reset the bios, or at least by-pass the bios-password. Any help would be really appreciated.

The best model number that I can find on the bottom labels is : F3466JT

All 4 laptops are identical (they are part of a Wireless Lab setup)

Your best solution would be to Flash the BIOS to the latest version or if it's already installed just rerun the BIOS Upgrading program with the same BIOS Version. That should clear out the installed Passwords but you'll have to reset the BIOS after Flashing it.

Password cracking software

The following software can be used to either crack or reset the BIOS on many chipsets. If your PC is locked with a BIOS administrator password that will not allow access to the floppy drive, these utilities may not work. Also, since these utilities do not come from the manufacturer, use them cautiously and at your own risk.

Using the Motherboard "Clear CMOS" Jumper or Dipswitch settings

Many motherboards feature a set of jumpers or dipswitches that will clear the CMOS and wipe all of the custom settings including BIOS passwords. The locations of these jumpers / dipswitches will vary depending on the motherboard manufacturer and ideally you should always refer to the motherboard or computer manufacturers documentation. If the documentation is unavailable, the jumpers/dipswitches can sometimes be found along the edge of the motherboard, next to the CMOS battery, or near the processor. Some manufacturers may label the jumper / dipswitch CLEAR - CLEAR CMOS - CLR - CLRPWD - PASSWD - PASSWORD - PWD. On laptop computers, the dipswitches are usually found under the keyboard or within a compartment at the bottom of the laptop.
Please remember to unplug your PC and use a grounding strip before reaching into your PC and touching the motherboard. Once you locate and rest the jumper switches, turn the computer on and check if the password has been cleared. If it has, turn the computer off and return the jumpers or dipswitches to its original position.

Many HP notebook PCs have no back-door for the password, and are pretty much crack immune.

Per HP, on many models, the only way to recover from a lost BIOS password is to physically replace the BIOS IC.

You then need to flash the BIOS and start over.

One big problem is that the Flash ROM on a notebook is a surface mount IC soldered to the board. You need the right tools, and very good technique to remove a surface mount IC without damaging the circuit board.

Search HPs web site with the specific model and serial number to verify if these need to have the BIOS IC replaced to recover from a lost password.

If they do not require replacing the IC, a HP service center should be able to clear the password for you.
