OEM EOSL Calendar · Lenovo
Lenovo EOSL Calendar — every milestone date, every active model
Lenovo Premier Support renewal makes sense while ThinkSystem firmware feature evolution is active. TPM economics start to win at year +3 post-EoS on stable virtualization fleets, particularly SR630 / SR650 first-gen and SR850 / SR860 platforms. WUC supports all Lenovo platforms below indefinitely post-LDoS.

How to use this calendar
The 30-day fleet review procedure.
If you maintain a Lenovo fleet of any size, this four-step pass yields a 36-month refresh-and-TPM roadmap.
- 1
Pull asset inventory
Export your Lenovo fleet from CMDB / spreadsheet / OEM portal. Minimum columns: serial number, model, install date, support contract end date.
- 2
Map against this calendar
Cross-reference each model against the table above. Flag every unit where LDoS lands within your refresh planning horizon (typically 18–36 months).
- 3
Bucket by economics
For each model bucket: refresh-now (year +1), refresh-soon (year +2), TPM-and-hold (LDoS +1 or beyond), evaluate-app-stack (LDoS dependent on application lifecycle).
- 4
Cost-compare per bucket
For TPM-and-hold gear, compare current OEM renewal cost vs WUC TPM quote vs replacement TCO. The math typically favors TPM at LDoS minus 12 months and beyond.
Run your Lenovo renewal numbers against a real alternative.
Bring four data points to a 60-minute call and we'll map your Lenovo fleet sequence:
- Current Lenovo asset count
- Annual OEM maintenance spend
- Contract anniversary distribution
- Asset visibility state (CMDB, spreadsheet, none)
