Usually you need to remove the keyboard from the laptop, and the cmos batery should be visible.
the screws for the keyboard should be marked on the base
hope you have a manual as the IBM website is a nightmare

Batteries non reconnues


google translated
Battery not recognized
make sure the battery has a secure dust free seating and has charge

If there is no charge from the CMOS battery, or little charge even, you will notice your clock set to 12:00 and the date to Jan. 1 every time you start your computer.

Your computer will also ask you where it should boot from when you turn it on.


These are the most basic signs your CMOS battery is going dead and will be your ultimate test of the battery
(some motherboards cmos batteries are soldered in)

hope this helps

How to verify that the CMOS battery needs to replace


<p>The CMOS battery is named after the Complementary Metal Oxide Semiconductor power. The CMOS has the current date and time functions for desktop and laptop computers. It allows the computer to automatically adjust the time, even on computers that are disconnected for long time. When a computer no longer has the date and time and forget it on every boot, the CMOS battery probably needs replacing. Some computers have messages when the battery is weak, while others just lose the current date and time after each shutdown.<br /> <p>Time & Date Errors<span> </span><br /> <p><span> </span><br /> <p>1. Turn on the computer. Look in the task bar at the bottom right. Make sure the date and time is set correctly. Double-click the time and click the up or down arrow to switch to the correct time. Click on the arrow next to month to change the month. Click "OK" when finished.<br /> <p><br /> <p>2. Turn off the computer. Wait 3 to 5 minutes and start the machine.<br /> <p><br /> <p>3. Look on the taskbar to see if time was lost and said a strange date January 1, 2000. Replace the CMOS battery, if this is the case.<br /> <p><br /> <p>CMOS Error Message<br /> <p>1. Look for error messages like "CMOS checksum error", "CMOS Read Error" or "CMOS battery failure" when you start your computer. These errors are caused in the machines shut down for several months or when the CMOS must be replaced.<br /> <p><br /> <p>2. Let the computer on for 24 hours. Restart the computer and find the error.<br /> <p><br /> <p>3. Change the CMOS as the return error.<br />

Cmos battery error failure


The CMOS (BIOS) battery keeps the computer'a comfiguration and the Date & Time settings in the CMOS (BIOS) chip in its memory. When the CMOS (BIOS) battery is flat these configuration information is lost.
Replace the CMOS battery with a new one, in most cases this battery is a lithium 3 volt battery type CR2032 and it is coin size battery 18mm in dia.(check it to make sure the type of battery is installed on your motherboard).
When you replace this battery then go into the BIOS and set the Date & Time etc.

How to get a valid yahoo certificate update because mine got expired


Hi there, the simplest way to resolve certification error is by fixing your computer's date. If the clock's date was set wrong, then it sends expired security certificates. I hope that helps.

Cmos checksome error


I don't know what kind of unit you are useing.
You need to watch the screen when it boots up.
It will say check sum error, press ? F-2 to continue or F-1 to enter setup.??
Enter the setup screen and change the date and time.
Save ? F-10 and exit.
I hope this has helped you.

The 161 CMOS error means the CMOS/BIOS battery is dead/flat and needs to be replaced.
The 163 CMOS error means the Date and Time could not be updated when you change the Date and Time setting. This is caused by the flat CMOS/BIOS battery.
When you replace the battery with a new one, the BIOS will go back to the default settings, go into to BIOS setting (press F2 when you boot up) and change the Date and Time, then save and exit.

This is likely your CMOS battery dying on you and resetting your computer's date. Hitting F2 I belive it is will allow you to access your bios and on the second page you can see your date. It will likely be Jan 1st, 1988. Use your number keys to adjust the date and use your tab key to move between month, day, year, ect.

This is a temporary fix however and you will have to do this often until you have your CMOS battery replaced. I have a Travelmate that has the same problem.
