Question about HP Elitebook 8530w Notebook
Posted by Anonymous on
To Remove the CMOS battery:
1. Position the computer upside-down with the front toward you.
2. Loosen the two Phillips PM2.0×5.0 captive screws (1) that secure the memory module compartment cover to the computer.
3. Lift the right side of the cover (2), swing it up and to the left, and remove the cover. The memory module compartment cover is included in the Plastics Kit, spare part number 495076-001.
4. Disconnect the RTC battery cable (1) from the system board.
5. Slide the RTC battery (2) out of the rubber pouch on the bottom of the system board.
Reverse this procedure to install the RTC battery.

There is also usually a "jumper" that you can do this with. You would have to look up your make and model on the manufacturers site.
The cmos batter just flicks out. It's held in by a med loose spring. Once out leave it for 5 mins for replacing it.

There are 2 ways you can reset your bios.
1. On the motherboard there is a small watch battery. Remove this battery along with the power cable from the power supply. Hold down the power button to fully discharge the system. Wait 2-3 minutes then reinstall the battery and plug in your system. Your reset is now complete
2. Some motherboards have a 3 pin jumper by the battery. Lets say that the jumper is on pins 2 and 3. Remove the jumper while the machine is OFF and place onto pins 1 and 2. Power on your machine for a minute. (Note: Your system will not POST). Shutdown your machine and put the jumper back to pins 2 and
3. Your reset is now complete
There might also be an option within the BIOS to "Load Defaults" if that is all you are looking to do

hope it helps!

If you have forgotten your BIOS or system password, there are no software tricks or magical gimmicks that will get the password cleared. Laptops are different in that they are designed to not work with “backdoors” etc. for security reasons. There is one true way that works most of the time and that is hardware.
The Cmos (RTC) battery that is mounted on the motherboard in most cases holds the key, if your motherboard has the battery that is connected to the motherboard by using a two wire socket that plugs into the MOBO, then here is the procedure.
On the motherboard where the battery plugs into, you will see two pins sticking straight up, these engage the plug on the battery side. These two pins have to be “shorted” and then the motherboard powered up for approx. 30 seconds, then power down the system and replace the Cmos battery and reboot. Your password problem should be cleared up. The best way to “short” the pins is get another cmos battery and cut the wires from the battery part, bare the ends and twist together, this will short the pins. Make sure you tape the connection good on the jumper you just made….don’t want to touch anything else with powered up bare wires. Below is the link to your service manual that will point everything out to you. Good luck.

Tips for a great answer:

Open up your computer case. You need physical access to the motherboard to complete this procedure
Find a circular, (mostly) silver metallic object on the motherboard. This is the CMOS battery
CAREFULLY remove the CMOS battery, avoid touching it with your fingers, and leave it out for about 120 seconds. This will flush the CMOS memory which stores the BIOS password and all other configuration. (See Warnings)
Set the battery back into place and power on the computer
The computer should then warn you that the CMOS configuration could not be found. You can either reconfigure it yourself or restore defaults. Restoring the default configuration should be fine.
You will notice that the BIOS password has been cleared and you can boot without it. You may reset the BIOS password to something else by going into the BIOS configuration and setting a new User Password (The Supervisor Password controls access to the BIOS, NOT the computer!)
Hope this helps
