The RTC battery is inside the laptop connected by a two wire connector. it generally resembles a large button type battery. The laptop will have to be taken apart and the top panel removed to be able to get to it.

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 />

Need to replace cmos battery in Gateway MP8708


Power down PC. Open the PC tower. Look at the motherboard and find the CMOS battery. Looks like the picture below. Make sure you touch some sort of metal area on the PC to ground yourself before touching the components. Use something thin to pop the old CMOS battery out. The CMOS batteries are usually universal. CR2032 is the usual type used. These can be found at a CVS or Walgreens. Once you have acquired the next battery, make sure the CR2032 is facing up and just press it in.

Got message "CMOS battery low" What steps are


Assuming you know how to get into your computer and identify the CMOS battery, you just need a pair of tweezers or similar to remove the battery. Once it has removed, take it into a drug store or pharmacy and find the exact same battery, and replace it in the motherboard. If you can't identify the CMOS battery, please let me know and I can help you with that.

This is a typical sign that the CMOS battery (the coin-shaped battery on the motherboard) has failed & needs to be replaced. After replacing the CMOS battery, you will need to boot into BIOS & save CMOS settings.

How do I replace a dead cmos on acer 4520LCi travelmate laptop? The laptop no longer keeps track of system time when shut off completely. Can you tell me the exact location of the cmos so I can be able to...


Hi,

what you replace is not the CMOS, but the CMOS battery.

On an ACER from those years the CMOS battery looks like a coin, or a coin wrapped in plastic and connected to the motherboard.

On most models from same series the battery is located on the lower side of the motherboard, like on picture below:

On some model the battery may be located underneath the keyboard.

Here disassembly instructions for a similar model.
