The CMOS battery is located underneath the keyboard as well as one of the two memory slots. To get at it, you have to remove the “Hinge Cover” and then the Keyboard.
To remove the “Hinge Cover” (The hinge cover has the ON/OFF button) follow these steps:
1) Remove the battery and AC power.
2) In the battery bay you’ll see 2 small Phillips screws. Remove these screws.
3) Turn the laptop right side-up and using a small screwdriver, pry up on the notch on the right side of the hinge cover.
4) Lift and remove the hinge cover from the laptop.
5) Carefully lift the keyboard and gently slide it towards the LCD. (CAUTION! The keyboard is connected to the motherboard with a ribbon cable. Be careful not to damage the cable on the underside of the keyboard.)
6) The CMOS battery is located on the right side of a small white ribbon cable. It’s about the size of a small coin.
Hope this helps.

How do I replace a y510 cmos battery


Hello,

Locate your CMOS battery

Caution: When inside your computer make sure you're aware of ESD and all it's potential dangers.

cmos.jpgOpen the computer case and find the battery on the computermotherboard, 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 refer to your motherboard or computer documentation or contact your computer manufacturer for additional assistance in locating it.

Obtain battery information

Unfortunately, most manufacturers will not list the exact type and model of your CMOS battery; therefore, once you have located the battery, write down all information about the battery (Voltage, chemistry, wiring, and packaging). If possible, remove the battery and take it to the location you plan on purchasing a new battery from. The part number for this battery for most computers is CR2032.

Additional buying information can be found on our battery buying tips page.

Removing the battery

Caution: When inside your computer make sure you're aware of ESD and all it's potential dangers.

If you're computer is using a coin cell battery similar to the above example picture. Removing the battery is relatively simple. 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 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 resetting the CMOS values to the defaults. 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 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 supply or bad motherboard.

Tip

CMOS Checksum error


Issue:
CMOS Checksum Bad or CMOS Date/Time Not Set


ae4e911.jpg
Cause:
This issue is caused when the CMOS values are incorrect. This issue can occur because of any of the below possibilities.
* Bad or old CMOS battery.
* BIOS update.

Workaround 1:
1. Disconnecting power from computer without shutting down computer.
2. Attempt to reboot the computer. If error still occurs after rebooting the computer enter CMOS setup and check all values, this includes verifying the time and date are correct. Once everything has been verified and/or changed make sure you save and exit CMOS setup.
3. If you have a Phoenix BIOS and have an option for 'Reset Configuration Data', set this value to 'Yes' and save and exit the CMOS.
4. If the computer was had the power disconnected while it was still running it is possible this could cause the CMOS to become corrupt. Ensure that the computer is ready to be shut off before turning off the computer. If you have a laptop computer ensure that the battery is charged before disconnecting the power connection.
5. If the CMOS values have become corrupted entering the values in CMOS setup and saving and exiting CMOS should resolve your issues.
Note: If this issue continues to occur after you turn off your computer off it is possible that the CMOS battery may be failing or already bad. Before considering replacing the CMOS battery try leaving your computer on for several days.
Workaround 2:
If you performed workaround 1 and the error occurs again after a complete power down (i..e. removing the power cord), the CMOS battery is likely bad. Most systems use a small coin style lithium battery. These often last 3-6 years, but at some point run out of juice and need to be replaced. For desktops, your system manual or motherboard manual should specify the type of battery and location on the motherboard. For laptops, it is often very difficult to access and may require a professional to replace it. To replace the battery on a desktop system:
1. Turn off the system and remove the power plug.
2. Remove the case or side panel to access the motherboard.
3. Look for a round silver coin cell, typically in a black holder.


06928b6.jpg
4. Remove the battery while noting which way the battery is located. You may need a small flat screwdriver to release the side clip.
5. Install the replacement battery with the same battery type, being careful to insert it in the same direction as the removed battery (or using the polarity marked on the holder or manual).
6. Reassemble the case and power.
7. Turn on the power. You will get the CMOS Checksum Bad error once more, but it should be the last time. Go into the BIOS setup and set the date and time, and any other options you prefer.

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.
