Lenovo 5WS1X47535 4-Year Premium Care Plus Upgrade

Extend an existing 1-year Lenovo Premium Care Plus entitlement to a 4-year service term while adding 4-year battery coverage. Lenovo 5WS1X47535 is a service upgrade rather than a device component or standalone battery. It applies to supported Lenovo systems that already have the required 1-year Premium Care Plus starting coverage, making it relevant when a system will remain in use beyond its initial protection period. The entitlement makes two stated coverage changes: it extends Premium Care Plus from 1 year to 4 years and upgrades battery coverage to the same 4-year duration. Keeping both terms at four years matters for systems expected to remain assigned through a longer refresh cycle, where battery coverage may be evaluated alongside the primary service entitlement. Use this upgrade where the covered system, its existing protection level, and its service-region eligibility match the plan requirements. It is differentiated within the Premium Care Plus service range by its upgrade path from 1-year coverage and its included battery-term extension. The result is a single 4-year protection period for the eligible system and battery coverage specified by the plan.
