I am trying to locate the cmos backup battery in my Gateway Solo 3350 laptop as it has died and I want to replace it. Can you describe where it is located, and how may I get at it? Ian Hawke

    Thanks for your response, but it did not answer my original question, and that is:- how do I physically get the computer apart to get at the battery without destroying the case in the process?
    I have removed all the screws that I can get to, but the keyboard retaining screws are still inaccessible. Obviously, there is a trick to getting the top escutcheon moulding off, and I have tried prying it away with as much force as I dare use, but to no avail. Can you please offer advice?

Download manual for a another Gateway laptop that illustrates you the steps to disassemble the laptop.

I could have given u manual steps. However, I think the manual will describe the best practise.

Hope, this helps.

If your computer is losing its time or date settings, or you are receiving a message CMOS Read Error, CMOS checksum error, or CMOS Battery Failure, first attempt to leave the computer on for 24 hours. In some cases this can charge the battery and resolve your issue. This often resolves CMOS battery related issues when a computer has been left off for several months. If this does not resolve your issue follow the below steps.
Write down all system settings
Ensure that the information within your CMOS, if not already lost, is written down. If you're getting a CMOS error message or your time is not being saved your settings are already lost.The procedure to get into CMOS is :-

Because of the wide variety of computer manufacturers and BIOS manufacturers over the evolution of computers, there have been numerous different ways to enter the BIOS or CMOS Setup. Below is a listing of the majority of these methods as well as other recommendations for entering the BIOS setup.
Notice: If you are unable to get into the BIOS or CMOS setup because of a password please see document CH000235.
New computers
Thankfully, computers that have been manufactured in the last few years will allow you to enter the CMOS by pressing one of the below five keys during the boot. Usually it's one of the first three.

  • F1
  • F2
  • DEL
  • ESC
  • F10
A user will know when to press this key when they see a message similar to the below example as the computer is booting. Some older computers may also display a flashing block to indicate when to press the F1 or F2 keys.
Press <F2> to enter BIOS setup
Tip: If your computer is a new computer and you are unsure of what key to press when the computer is booting, try pressing and holding one or more keys the keyboard. This will cause a stuck key error, which may allow you to enter the BIOS setup.
Older computers
Unlike the computers of today, older computers (before 1995) had numerous different methods of entering the BIOS setup. Below is a listing of general key sequences that may have had to be pressed as the computer was booting.
  • CTRL + ALT + ESC
  • CTRL + ALT + INS
  • CTRL + ALT + S
If your computer is unable to boot or you wish to restore the BIOS back to bootable settings and your computer uses an ACER BIOS, press and hold the F10 key as you turn on the computer. While continuing to hold the F10 key, you should hear two beeps indicating that the settings have been restored.
Older AMI BIOS could be restored back to bootable settings by pressing and holding the insert key as the computer is booting.
BIOS / CMOS diskettes
Early 486, 386, and 286 computers may have required a floppy disk in order to enter the BIOS setup. These diskettes are known as ICU, BBU, and SCU disks. Because these diskettes are unique to your computer manufacturer, you must obtain the diskettes from them.

Locate your CMOS battery
Open the computer case and find the battery on the computer motherboard, verify that it will be accessible and that it can be removed. Most computers today use a coin cell CMOS battery as shown in the image to the right.
If you are unable to locate your CMOS battery you will need to refer to your motherboard or computer documentation and/or contact your computer manufacturer for additional assistance in locating it.

    Removing the battery

    Caution: While in the computer make sure
    you're aware of Electro Static Discharge ( E.S. )
    your computer is off, and that you're properly grounding yourself.
    Especially before removing the battery.

    If you're computer is using a coin cell battery
    similar to the above example picture. Removing the battery is
    relatively simple. Simply use your fingers to grab on the edge of
    the battery and pull it up and out of the container holding it. Some
    motherboards have a clip holding the battery down. If your computer
    has this clip you may need to use one had to move the clip up and
    the other hand to pull the battery out.

    Unfortunately, not all CMOS batteries are
    removable; some manufactures will only allow a replacement battery
    to be added. If you're not using a coin cell battery and are
    not able to determine how to remove it refer to your motherboard or
    computer documentation and/or contact your computer manufacturer for additional assistance in removing the battery
    or how to insert a new replacement battery.

    Users with computers that do not have removable
    batteries only options to install a new battery will most likely
    also need to set a jumper when
    adding the new battery into their computer.

    Insert the new battery

    Once you have purchased a new battery, remove the old
    battery (as instructed above) and replace it with the new battery.

    Enter CMOS values

    Once the battery is replaced turn on the computer and enter all values back
    into CMOS or set the values back to the default settings.
    Additional information about getting the values back to default can
    be found on document CH000970.

    After the values have all been entered make sure to
    save the settings before exiting. Many CMOS setups allow you to
    press a key (such as F10) to save values and exit all in one action.

    If after following all the above steps you continue to experience
    the same error when your computer starts and/or your computer is
    still unable to keep the stored values it's likely that you're
    experiencing a more serious issues. Most likely causes are bad power suppy or bad motherboard.

    Hope i helped you.

    Thanks for using "Fixya".

CMOS location in gateway model # 6332

The CMOS battery on the Gateway M-6332 is located either next to or underneath the WiFi card. With the laptop upside down, loosen the three screws along the rear edge of the panel next to the fromt of the laptop. Remove the panel and you'll see the hard drive and the WiFi card. There will be one or two Mini PCI Express slots. I've replaced the mainboard in this one, don't recall if the original only had one slot, the one I installed has two.

That's where the CMOS battery is, held to the board with a piece of double sided tape and connected by a pair of wires to a small plug.

I forgot my gateway model ML6230 bios password, i need a new password for it (reset the password).

A method you can try if you don't have a password reset software is by removing the CMOS battery. Remove the CMOS battery then turn the computer on. The system BIOS will be reset and password will be removed. Then you can put the battery back in. Click on this link for the Gateway ML6230 Notebook PC Manual. Check page 36 for CMOS battery removal instructions.
