I Need to know how to reset the bios jumpers on a HP g61 notebook can anyone help ?


This information is intended for experienced users. It is not intended for basic users, hackers, or computer thieves. Please do not try any of following procedures if you are not familiar with computer hardware. I'll not be responsible for the use or misuse of this information, including personal injury, loss of data or hardware damage. So use it at your own risk.
A. By Using the Motherboard Jumper:
In most motherboards CMOS battery is soldered, which makes it difficult to remove the battery. In this case we use another method.
Almost all motherboards contain a jumper that can clear all CMOS settings along with the BIOS password. The location of this jumper varies depending upon the motherboard brand. You should read your motherboard manual to check its location. If you don't have the manual then look for the jumpers near the CMOS battery. Most of the manufacturer label the jumper as CLR, CLEAR, CLEAR CMOS, etc.
When you find the jumper, look carefully. There will be 3 pins and the jumper will be joining the center pin to either left or right pin. What you need to do, is remove the jumper and join the center pin to the opposite pin. e.g. if the jumper joins center pin to left pin, then remove it and join center pin to right pin. Now wait for a few seconds and then again remove the jumper and join the center pin to left pin.
Make sure to turn the PC off before opening the cabinet and resetting the jumper.
B. By Using Software:

I have found that BIOS/CMOS Password Recovery Tool is the most effective.:
BIOS/CMOS Password Recovery Tool is a program that works instantly to remove any lost or forgotten BIOS/CMOS password. Simply boot your PC to DOS and execute the program, and get access to forgotten BIOS/CMOS passwords in just seconds

Forgot my password


In computing, BIOS (basic input output settings) refers to the information stored regarding a computer's hardware configuration, the system date and time and any applied password. This information is known as the BIOS or CMOS settings--the BIOS is stored on a small battery-powered semiconductor chip known as the CMOS (complementary metal oxide semiconductor). Having a CMOS or BIOS password restricts unauthorized changes to the system's hardware configuration and, in some computers, may even be required for booting. A lost password may be reset by removing the CMOS battery, clearing the motherboard jumper or using a software-based password cracker.

1.Shut down the laptop and unplug its power cord from the wall outlet. Remove the battery cover under the laptop and gently raise the battery from its dock. Unplug any peripheral devices with a live power source connected to the laptop, such as a modem or printer.
2.Locate and remove the CMOS battery. Refer to your user manual or visit the manufacturer's website for your laptop's architecture. Follow manufacturer recommended procedure to access and remove the CMOS battery. Depending on make and model, this procedure may be more involved for some laptops and not others. The CMOS battery is a flat circular shape and resembles a watch battery.
3.Wait 30 minutes and then put the battery back in. This will erase all information stored in BIOS. Assemble the laptop, making sure you leave no loose connections. Power up the laptop and press "F1" when you get the "CMOS cheksum error" message. Type in a new password.

Clearing CMOS Jumper

1.Turn off the laptop and access the motherboard following recommended procedures.
2.Locate the jumper in the motherboard. If you do not have your motherboard documentation, locate a single jumper near the CMOS battery. In some laptops, the jumper may also be labeled in the motherboard. Put the jumper setting to "Clear" and reassemble the laptop.
3.Turn on the computer and hit "F1" when the "CMOS checksum error" message is displayed. Navigate through the BIOS settings interface to load default settings and apply a new password.

Using Password Remover

1.Download a software-based BIOS password cracker. There are numerous free programs able to recover or delete CMOS or BIOS passwords from virtually all motherboard brands. Download the file from a trusted source and save it to the desktop.
2.Burn the installed file to a CD using image burner software. Insert the CD and access the password remover tool.
3.Note the password or use the program to set a new password.

I hope you find it very helpful. Thank you.

Where is the onboard battery located on the HP Pavilion ze4420us notebook, and easiest way to access it


The CMOS battery is on the motherboard, and you need to disassemble the laptop to get at it. You can download the Maintenance and Service manual from HP here, which details the procedure. It's tedious, involving lots of screw removal (and taking notes about which screw came from where, as several different lengths are used). The battery itself is a small coin cell type with wire leads that plug into a connector. I don't remember what battery type is used and how hard it is to get, but once you have it out you can check the part number and look for it online. Good luck, and thanks for using Fixya!

HP Pavilion dv6000 laptop


This can be a Hardware issue.

Try the steps below :


1. Disconnect the AC Adapter.
2. Remove the Battery.
Note : Please see that there are no external devices or cables connected to the Notebook.
3. Hold the Power button down for 30 seconds to 1 minute.
4. Reconnect the AC adapter and do NOT connect the battery now.
5. Turn on the Notebook power.

If the Notebook starts normally, the issue is resolved...

However, if the issue persists, I recommend you to try removing and resating the Memory(RAM) of the Notebook by following the instructions available in the Manual which can be accessed from the link below :

http://h10032.www1.hp.com/ctg/Manual/c01035677.pdf

Find the required instructions to remove and reseate the memory starting from page number 128 of 278 in the Manual.

If the issue persists, it can be a Hardware issue for sure.

However, HP had identified some hardware issues with some Notebooks.

Get the Product Number of the Notebook which can be located form the bottom of the Notebook indicated with P/N and check if it is listed in the list available in the link below :

http://h10025.www1.hp.com/ewfrf/wc/genericDocument?lc=en&cc=us&dlc=en&docname=c01300427#c01300427

You can get the Notebook repaired for free if it is purchased and currently available in US or Canada.

Find more information about this from the link below :

Password trouble


If you are talking about BIOS Password which is being asked when you try to access any feature of the BIOS, I am sorry, it is not possible to retrive.

However, if it is the Startup Password which is prompted to enter immideatly you start the Notebook, you can try removing and replacing the CMOS/RTC/BIOS Battery.

1) Turn off the Notebook and remove the Battery and Power Adapter.

2) Follow the instructions to remove the BIOS Battery provided in page number 125 of 310 in the manual :

http://h10032.www1.hp.com/ctg/Manual/c01035657.pdf

Start the Notebook with the CMOS battery removed with the power adapter and turn it off once you see the HP logo.

Remove the Power adapter and insert back the CMOS Battery and fix the door that covers it.

You should be able to go ahead with no issues.

If you are talking about Login Password after booting into the Operating System, it may not be possible untill you are not using the Administrator account.

Press hold the Ctrl and Alt keys and press the Del key twice.

This will get a window in which you need to enter the Administrator as the User name and Enter the password if you have set any....leave the Password column blank if you have not assigned any administrator password.

Once you are loged in, reset the password of the account which you are unable to login to.
