RTC Battery Substitution on 11th Gen Intel® Core™
If the RTC battery repeatedly gets drained, the capacity will degrade, requiring the coin cell to be replaced. As an alternative to this, we''ve created an RTC Battery Substitute module that can be inserted in place of the coin cell, allowing the RTC circuit to remain powered whenever either the main battery or external power is present.
