SOURCE: want to replace cmos battery in Toshiba Satellite A10

On Toshiba laptops you hit the ESC key as soon as you turn it on & then you
are given the option to hit the F1 key to enter bios.


As to the cmos battery, they couldn't have hidden it better if it was the Queen's diamond!

It is near the bottom of the laptop on the right side, almost directly beneath the pause/break key.
Problem is, you have to disassemble the entire laptop to get at it!

Disassembly instructions for the Satellite A10 are here

SOURCE: Trying to locate the cmos battery for Toshiba Satellite L25-S121 laptop?

On the Toshiba Satellite L25 S1217 Laptop, the battery is indeed to the left of the wifi card. I was having a problem with a bios password and had spent a considerable amount of time looking. However Instead of taking the whole laptop apart, I removed the wireless card and used a precision flathead to maneuver the connector out of it's socket. after a few seconds I booted the laptop, with the battery still disconnected , and no password prompt! using the same screw driver, I was able to get the connector back into it's socket, and put the wireless card back in. it runs fine now. the trick is to only pull the connector out only enough so that it's not making the connection, if you pull it too far you will have a tougher time guiding it back into the socket. I hope this helps a lot of people with the same problem.

SOURCE: Dell C610 battery cmos/bios

The removal and replacement instructions can be found in the dell service documents available at support.dell.com. You can look it up by service tag or model number. But in short, the procedures are. 1. Remove the hard drive, then remove the keyboard. The keyboard is removed by removing the 5 screws on the bottom of the laptop marked with a "K" beside them. Then the keyboard can be removed. be careful not to tear the ribbon cable, and you do not have to remove the ribbon cable. The battery will be in the center of the opening, it will have a white plug that plugs into the keyboard. Contrary to Ayyasam's recomendations above, it is not necessary to remove "all" the screws on the bottom, nor is it necessary to remove the bottom of the laptop. It should be a 5 minute project. Again for any Dell item, the factory repair manuals are available online, and have exact instructions including pictures and diagrams.

Happy Computing

How to change cmos battery


Locate your CMOS battery
cmos.gifOpen 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.
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.
Additional buying information can be found on our battery buying tips page.
Removing the battery
Caution: While in the computer make sure you're aware of Electro Static Discharge (ESD), 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 supply or bad motherboard.

Trying to get the backup battery out but cant find it need help to tell me where it is


Once you remove most of the casing to your notebook and gain access to the motherboard look around the corners and all over it. There will be a button batter about the size of a quarter or smaller on the motherboard. It may be sitting in a socket designed for the button cell battery or it may be wrapped in black shrink tape and plugged into the motherboard by red and black wires.

Lost system password


Only way to remove a BIOS password on any computer is to remove all power sources from the motherboard so its memory can be cleared.

First, remove the main battery from the laptop. Then you must locate and find the little coin cell battery (It looks like a watch battery) on the laptop and remove it for about a minute or so. Then you can replace them in the opposite order.

Your coin cell battery is in a bay on the bottom of your computer. Enjoy!
1. Before removing the coin battery:
2. Locate the memory module cover on the bottom of the system.
exmem01.jpg 3. Use a Phillips screwdriver to remove the two screws securing the cover.

4. Lift and remove the cover from the system.

5. Locate the coin battery.

6. Use a fingernail (or small flathead screwdriver, if necessary) to release the battery ZIF connector.

8. Reverse the previous steps to replace the coin battery.

Unfortunately, some laptop coin cell batteries are difficult to locate, or require an in depth dissection of the laptop to get to them. Without the model of the laptop, I cannot tell you how to get to it.
