Question:
Where is the CMOS battery on an Aspire 4315 laptop?

Under the keyboard? Then how do I remove the keyboard? Specifically to the Aspire 4315, without damaging the laptop. Reach it through the back cover? Remove the cover and then what? Specifically where is the CMOS battery on this model of laptop? If there is a clear CMOS jumper on this model, then specifically where is it? Presumably under the back cover. That would be the most sensible. But where?
If you know then thanks in advance for sharing. I have noticed others getting unhelpful answers like "on the motherboard" and feel their frustration. So thanks again for detailed answers.

Locate your CMOS battery



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



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 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.

Where all of them are for laptops, on the motherboard.

You will need to completely dismantle the laptop to get to it. I know, it's a pain in the but....

If you are trying to just reset a forgotten BIOS password, there are ways to do that without clearing the CMOS. Anyway, I was never able to understand why people even bother to set BIOS passwords to start with. I've been using computers and laptops for over 14 years now and I never had the need for that.
