Are you experiencing issues with your Surface Pro 3’s date and time resetting constantly? Or maybe your system is struggling to boot up properly? These could be signs that your CMOS battery needs replacing. While it might seem daunting, changing the CMOS battery on your Surface Pro 3 is actually a fairly straightforward process. This guide will walk you through each step, making it easy for you to tackle this common repair.
Understanding the CMOS Battery
The CMOS battery, also known as the real-time clock (RTC) battery, is a small, coin-shaped battery located on your Surface Pro 3’s motherboard. Its primary function is to power the system’s BIOS (Basic Input/Output System) and keep the date, time, and other system settings stored even when the device is powered off.
Over time, the CMOS battery loses its charge, leading to various issues. Here are some common symptoms:
- Date and Time Resetting: The most obvious sign is the date and time constantly resetting to default values.
- Boot Issues: A faulty CMOS battery can cause problems during the boot process, leading to slow startups, error messages, or even complete failure to boot.
- System Settings Reset: You might find that your BIOS settings, like boot order or system configuration, keep reverting to their defaults.
Preparing for the Replacement
Before you begin, it’s crucial to gather the necessary tools and prepare your workspace:
- A Phillips head screwdriver: You’ll need a small, precision screwdriver to remove the screws holding the Surface Pro 3’s back cover.
- A replacement CMOS battery: Make sure you purchase the correct type of battery for your Surface Pro 3. The most common type is a CR2032 battery.
- Anti-static wrist strap (optional): This helps protect your device from electrostatic discharge, which can potentially damage sensitive components.
- Clean workspace: A clean and dust-free surface will prevent any foreign particles from entering your Surface Pro 3 during the repair.
Disassembling the Surface Pro 3
With the necessary tools ready, you can start disassembling your Surface Pro 3:
1. Power off and disconnect: Ensure your Surface Pro 3 is completely powered off and disconnected from any power source.
2. Remove the kickstand: Gently detach the kickstand from the back of the device.
3. Unscrew the back cover: Locate the screws securing the back cover. Use your Phillips head screwdriver to carefully remove them.
4. Gently pry open the back cover: Once all the screws are removed, use a plastic opening tool or a thin, flat object to carefully pry open the back cover. Be cautious not to apply excessive force, as this could damage the device.
Locating and Replacing the CMOS Battery
Once you’ve removed the back cover, you’ll need to locate the CMOS battery. It’s typically a small, silver coin-shaped battery located near the motherboard’s edge.
1. Disconnect the battery: You might need to disconnect a small cable or connector that’s attached to the CMOS battery. This helps prevent any accidental short circuits.
2. Remove the old battery: Carefully lift the old CMOS battery out of its socket.
3. Insert the new battery: Place the new CMOS battery into the socket, ensuring it’s properly aligned.
4. Reconnect the battery: If you disconnected a cable, reconnect it to the new battery.
Reassembling the Surface Pro 3
After successfully replacing the CMOS battery, you can now reassemble your Surface Pro 3:
1. Secure the back cover: Carefully place the back cover back onto the device and align it properly.
2. Screw in the back cover: Reinstall all the screws you removed earlier, making sure they’re securely tightened.
3. Reattach the kickstand: Gently attach the kickstand back to its original position.
Testing and Finishing
Now that you have reassembled your Surface Pro 3, it’s time to test if the replacement was successful:
1. Power on your Surface Pro 3: Turn on your device and check if it boots up normally.
2. Verify date and time: Go to your system settings and check if the date and time are accurate.
3. Test BIOS settings: Access your BIOS settings (usually by pressing a specific key during startup) and see if any settings have been reset.
If everything is working as expected, you’ve successfully replaced the CMOS battery on your Surface Pro 3.
