Question about HP Compaq 6715b Notebook PC
I had a problem with my laptop a HP Compaq 6715b Notebook PC, I had to do a hard reset for my computer and when the computer was back online all of a sudden its asking for a power on password. Now I've looked around for the password but when i try to enter it nothing is showing up and it gives you three tries before freezing up. Can someone please explain to me how to get by this. I've already talked to HP about it and they said my warranty was up.
I had same issue. Called HP and they told me it wasn't covered under warranty (even though my laptop is still under warranty). They gave me a number to a local shop. I called the local shop and they told me they did not work on laptops! What a joke! Anywhoo, this laptop has gone through 2 HDD in about a year's time. Don't know if something is up with the power supply board maybe? Anywhoo...enough ranting. Here's what I did to clear up the issue:
Turn the laptop off.
Take the battery out.
There are 3 screws holding the laptop keyboard. Two of them are marked on the back and one is inside the memory/wifi card compartment. Take off the cover and there will be a screw on the left side (if you have the front of the laptop towards you).
Flip the laptop back right side up. Unlock the tabs that secure the keyboard in place by sliding them down. There should be 4 of them in between the F-keys. Lift the keyboard from the top, towards you. CAREFULLY. There is a ribbon cable that attaches the keyboard. Slide both little tabs up away from you on the side of the connector and slide the ribbon cable up.
The RTC battery should be right there. Slide it down and slightly to the left and it should pop right out. Wait about 10 minutes.
Plug the keyboard back in and plug in the AC adapter. Turn your laptop on. It should boot right up.
Don't know why this password got set on my laptop since I did not do it. I thought it was pretty sorry of HP to tell me that they don't cover this type of error even though I could prove that the laptop is legally mine.
You should also look into setting up a USB drive to be able to boot up some sort of Linux OS from it. (I use Ubuntu 9.10) Since Linux is not prone to viruses and .dll file issues like Windows. In fact, I'm writing this solution on FireFox browser using Ubuntu from my USB drive, while waiting for my new HDD to come in from HP. It's saved me on a few occasions. Another plus to doing this is that you can also scan the Windows folder on your HDD from Ubuntu to check for any viruses that are preventing Windows from booting up. Since you don't have to install it on your HDD, you're not affecting anything on your Windows partition.

Someone has put a power on password on your laptop. This password is setup from the BIOS configuration and the password is stored on an EEPROM chip, there may also be a password set on the hard disk which means that if you remove the hard drive from your laptop and insert it into another laptop, it won't work in the other laptop.
Also removing the BIOS battery to try and reset the BIOS will not work either.
There are no backdoor passwords you can use to get into your laptop.
IBM uses the same password protection method to protect your data from unauthorized access.
This is very very hard to crack, try to remember who used your laptop last and ask them the password, once you enter the correct power on password you then can enter the BIOS to remove the password or you can change it...
