* Un-mount your mainboard from your computer case and look for several screws on the reverse side of the board. Removing these allows you to remove the VRM heatsink. | *Un-mount your mainboard from your computer case and look for several screws on the reverse side of the board.

* If your model contains an RGB lighting assembly on the VRM heatsink watch for the cable that is attached to the mainboard to enable this. Remove that cable if present. | *If your model contains an RGB lighting assembly on the VRM heatsink watch for the cable that is attached to the mainboard to enable this.

* Locate the CMOS battery and unplug the leads. The leads should be a pair of black and red wires leading to a miniature mainboard plug. Unplug the connector. | *Locate the CMOS battery and unplug the leads. The leads should be a pair of black and red wires leading to a miniature mainboard plug. Unplug the connector. | ||
* Dismantle the wrapping on the battery unit itself and un-mount the leads from the battery surface by either force, desoldering, or clipping them. | *Dismantle the wrapping on the battery unit itself and un-mount the leads from the battery surface by either force, desoldering, or clipping them. | ||
* Solder each lead to a piece of nickle strip, and use a tackwelder to re-anchor each strip to the battery surface. Alternatively, simply wrap some electricians tape to re-anchor leads to the terminals though this solution will weaken over time. Upon completing this assembly to your satisfaction, move on to the next step. | *Solder each lead to a piece of nickle strip, and use a tackwelder to re-anchor each strip to the battery surface.

* Encase the new battery with electrical tape and re-mount it near the original location. Standard double sided foam tape should function nicely for this. Hotglue also works. | *Encase the new battery with electrical tape and re-mount it near the original location. Standard double sided foam tape should function nicely for this.
