I have the hp omnibook 500 plugged into the wall but im not getting in response, do i need to have anything else plugged into the laptop

I have had success is taking the backup battery out for at least 10 min ...you may be able to remove just the keyboard to gain access to it...just unplug it wait and re-plug it

Don't try anything. Simply contact the HP tech. support team. They will help u come out of the trouble.

You need to download the audio driver from the Compaq/HP WEB support/download page. Make sure you select your model laptop and the XP or Vista Windows version of the drivers you require.

push the screen to you and push it away so far as he can.

you hear a click the screen is fixed

most likely you got a bad battery take it back and have it replaced.
good luck

To recover your bios password you can read here in the HP Omnibook 500 service manual (page 107) where it states you'll need to contact HP and provide proof of ownership and they'll walk you through the process of resetting your password:

here are the instructions


-Remove the hard drive.
-Remove the keyboard.
-Disconnect the reserve battery cable from the system board connector.
-Pry the reserve battery free from the system board. The reserve battery is attached to the system board with a piece of adhesive tape.
-Remove any remnants of the adhesive tape from the EMI shield.

Step 2
Make sure all power is off/disconnected and batteries removed before attempting anything like changing parts
in HP > Compaq nx6310 is in a easy to get-to location, but changing it is a pain. Remove your main battery, you'll see a small square of silver plastic in the middle of the compartment. The CMOS battery is underneath of this square.
The battery's connector is on the mainboard, just below the area of the "ALT" key. Unfortunatly, you have to dissasemble the laptop to change it.
