SYSTEMS RELIABILITY & AI TRUST DIVISION — ADVISORY NOTICE (Updated on 29 November 2025)

Advisory ID: UMC-AI-1130-L5

Date Issued: 21 November 2025

Subject: Removal of Lenovo AI Now From UMC Fleet (Legion 5 Units) Following Expiration of UL Certification

1. OVERVIEW

This advisory is hereby issued to notify all departments and operational users that the Lenovo AI Now platform installed across the Legion 5 fleet will be decommissioned and removed on 30 November 2025.

The action is mandated due to:

  • the imminent expiration of the UL Solutions certification “AI Model Transparency Score — DIAMOND” on 29 November 2025, and

  • the absence of evidence of renewal from Lenovo (Beijing) as of the date of this advisory.

UMC/UMCIPC applies strict compliance rules: systems that rely on expired trust certification cannot remain in operational service.

2. EFFECTIVE ACTION DATE

ActionDate
Certification expiry29 November 2025
Automatic removal from fleet systems30 November 2025

Beginning 00:00 — 30 November 2025, all Legion 5 units will operate without Lenovo AI Now.

3. IMPACTED HARDWARE PLATFORM

DeviceStatus
Lenovo Legion 5 units under UMC operational fleetAI Now removal mandated
Other Lenovo devices without AI NowUnaffected

No hardware performance reduction is expected after removal.

4. RATIONALE

Although Lenovo AI Now received a UL DIAMOND rating, its scope does not cover factual accuracy or dataset recency. Recent evaluations discovered:

  • outdated model responses

  • speculative / fabricated answers stated as factual

  • user reliance risk in research and academic environments

Maintaining AI Now post-certification expiration would:

  • invalidate UMC trust compliance

  • risk misleading information exposure

  • potentially contribute to academic / operational data contamination

5. ACTION PROTOCOL

DateAction
Now → 29 NovSystem lockdown — monitoring, no new deployments of AI Now
30 NovRemoval package pushed to all Legion 5 units
Post-removalReplacement assistant evaluated (interim: offline mode only)

All user accounts will receive an action record confirmation automatically once the removal operation is logged.

6. USER GUIDANCE

Following removal, Legion 5 users should:

  • rely on traditional research sources and trusted cloud services

  • avoid citing historical responses generated by Lenovo AI Now without verification

  • report any residual AI Now interface access immediately

Attempts to manually re-enable Lenovo AI Now will be blocked by fleet security policy.

7. ADVISORY STATUS

🔹 ACTIVE — Pre-removal stage
Next expected notice:

  • UMC-AI-1130-L5-B — Completion confirmation bulletin (30 Nov 2025)

  • Certificate Expired: Lenovo AI Now (Beta) was archived from the Lenovo Support download database following the expiration of its UL Verification (ID: V848832). Once the certificate lapsed, Lenovo removed public access to the Beta software, signalling the end of its distribution and the conclusion of the Beta program.

How I Became a Proactive Battery Monitor (Catching Issues Early)

-
Author : Felisitas Faya P. Most users notice battery problems only after something feels wrong — shorter runtime, sudden health drops, or unstable charging. By that point, degradation has already accumulated. My goal was different from the start: catch battery issues early , before they become visible, irreversible, or expensive. The Beginning: Observing, Not Assuming (2022) In 2022, I began continuously monitoring battery health on my Lenovo Yoga Slim 7 Carbon 13ITL5. Using Lenovo Vantage Battery Details alongside HWiNFO’s tray monitoring, I tracked capacity, temperature, charging behavior, and long-term trends in real usage. The purpose wasn’t to follow battery myths or chase perfect numbers. It was to understand how batteries actually age over time — slowly, quietly, and often invisibly. Expanding the Scope: Gaming Laptops and Heat (2024) In early 2024, I expanded this monitoring to my first gaming laptop, the IdeaPad Gaming 3 15ACH6. This introduced new variables: higher power draw...
