*[Unconfirmed] : Replacement CR2032 for MSI Laptops that ship with the lead are available from third party vendors. The connectors from these products [https://forum-en.msi.com/index.php?threads/cmos-battery-replacement.391638/ appear to match the MSI mainboard plug]. If you have obtained one of these, skip the next 3 steps. | |||

Alternatively, simply wrap some electricians tape to re-anchor leads to the terminals, though be mindful, that tape adhesive will weaken over time, leading to possible loose connections. Tack welding is preferable. Upon completing this assembly to your satisfaction, move on to the next step. | ||
