Unplug the white connector attaching the CMOS battery to the motherboard. +5. To clear the CMOS, [disconnect the main battery](#replacing-the-main-battery), open the lid of the machine, and hold down the power button for at least 15 seconds to discharge any residual energy in the system. +6. Re-connect the CMOS battery and the main battery, and replace the SSD and bottom panel. +7. Power up the machine. The system may power itself off and on after initial boot; this is normal behavior when the CMOS has been reset. + +## Replacing the cooling system: + +If the CPU fan becomes noisy and cleaning it out doesn't fix the issue, you may need a new CPU fan. Contact support to start a warranty claim or parts purchase. + +Depending on your climate and the age of the machine, it may be necessary to apply new thermal paste between the CPU and the heatsink.

Slide the new speaker onto the plastic posts and connect it to the motherboard. + +## Replacing the main battery: + +The battery provides primary power whenever the system is unplugged. + +**CAUTION:** Do not use metal tools to remove the battery. Do not touch the battery contacts with your hands or metal objects. If the battery is damaged during repairs, do not reinsert it into the laptop. Do not continue to use the computer if it contains a damaged battery. It is a potential fire hazard to operate a computer with a damaged battery. Keep children away from, and properly dispose of, the damaged battery. Always dispose of batteries carefully, by placing a piece of tape on the contact points. Take damaged batteries to an electronics recycling center and contact System76 to purchase a replacement. Batteries may explode or leak if exposed to fire, or if improperly handled or discarded. Only use batteries designed for your specific computer. This product contains a rechargeable battery. The battery is recyclable. At the end of its useful life, under various state and local laws, it may be illegal to dispose of this battery into the municipal waste stream. Check with your local solid waste officials for details in your area for recycling options or proper disposal. + +**Tools required:** Cross-head (Phillips) screwdriver +**Time estimate:** 30 minutes +**Difficulty:** High ● + +### Steps to replace the main battery: + +1. Follow the steps above to [remove the bottom cover](#removing-the-bottom-cover). +2. Unplug the white connector that connects the battery to the motherboard. + +![Main battery](./img/battery.webp) + +3. Remove the battery. + - The battery is secured to foam standoffs with double-sided tape. + - A flat plastic object (such as a credit card) can be used to separate the tape from the battery. + - If any tabs from the tape are visible around the perimeter of the battery, do not push them back under the battery. + - Hold the tabs down while inserting the plastic tool to separate the tape and foam from the battery. + - Alternatively, pull the tabs up with the battery to separate the tape and foam from the chassis. +4. Put the battery back (or put your new battery in its place) and plug it back into the motherboard.
