Question about HP Computers & Internet
I am the only user, and my password is absolutely correct. If the CMOS battery is bad, is my password remains the same after replacing the battery? If not, how do I reset a new password?
The cmos battery holds your password and boot order settings on some motherboards removing the cmos battery will not remove password its held by a small chip which has back up power designed for this

SOURCE: CMOS battery replacement
Your Pc should have an Intel E210882 motherboard in it.
A coin-cell battery (CR2032) powers the real-time clock and CMOS memory. When the computer
is not plugged into a wall socket, the battery has an estimated life of three years. When the
computer is plugged in, the standby current from the power supply extends the life of the battery.
The clock is accurate to ± 13 minutes/year at 25 ºC with 3.3 VSB applied.
When the voltage drops below a certain level, the BIOS Setup program settings stored in CMOS
RAM (for example, the date and time) might not be accurate. Replace the battery with an
equivalent one. Figure 14 shows the location of the battery.
These batteries are very common and can be purchased at Wal-Mart, Walgreens, Etc...
Here is a link to the motherboard manual with battery replacement procedures:

There is a wafer lithium battery that maintains the power onboard the motherboard to maintain settings. The batter is located on the top side about midboard. Open the side of the computer case so that you have access to the motherboard. Before you remove the battery, you may want to carefully vacuum out the dust in the case and then use a can of air (available from Radio Shack or comuter supply store) to blow out the remaining dust.
You will need a replacement CR2032 Lithium batteery.
To replace the battery:
1 Remove the side panel that has the thumbscrews. See page 99.
2 Gently lay the PC on its side.
3 Remove any cabling, if necessary, to reach the battery.
4 Remove any memory modules, if necessary, to reach the battery.
5 With a flat screwdriver, press the metal latch that holds the battery in its
socket away from the battery. The battery will pop out.
6 Install the new CR2032 battery in the socket, with the positive (+) side
This should take care of your lost date.
Please rate this solution. Thanks.

Testimonial: "kitajib answered my question and solved my problem within 1/2 hour of posting my problem. He was able to tell me how to access the part."
SOURCE: I lost all password for
Lots of sites say to move the PSWD jumper (on the motherboard) from pins 1&2 to pins 3&4, or something like that. However on my Optiplex 360 I found that the PSWD jumper had only 2 pins. By trial and error I found that removing the jumper from these two pins while the system was off allowed me to boot the system with BIOS password disabled. I was then able to change BIOS settings (and install Linux - yeah!!).

if you have access to another computer and the internet, you can download software called password reset/recovery. these come with instructions on how to use. just use one of these to recover/reset your password and you should be able to access your computer again. Hope this helps :)

Try installing the system board driver and chpset driver.
You can also try setting the BIOS to factory default settings.
If you have a volt meter check to see if there is votage at the battery connector, and the power supply connectors are plugged into the mother board, which I suppose you are, just an idea, if the above suggestions don't resolve your issue.
I hope this helped.
Good luck and have a fantastic day.

Almost all motherboards use a small coin sized CMOS battery to store
all BIOS settings along with the password. To reset the password, unplug
the PC, open the cabinet and remove the CMOS battery for approx. 15-30
minutes and then put it back. It'll reset all BIOS settings as well as
the password and you'll need to re-enter all settings.
If it fails, then try to remove the battery for at least one hour.
B. By Using the Motherboard Jumper:
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.
