Dates are compiled from OEM end-of-life notices and third-party trackers and are provided for planning purposes only. Each entry shows its source; where the OEM publishes no model-wide date (for example, support set per serial number or service tag), we say so. Always confirm entitlement for your specific unit with the OEM. Listing a product does not guarantee coverage — to confirm support for your equipment.
