Legion 5: Under Warranty and Repairs

-

 We regret to report that our brand-new Lenovo Legion 5 (15AKP10, 2025) experienced a deep kernel-level AMD GPU driver failure. The issue manifested as an unrecoverable TDR (Timeout Detection & Recovery) event, where Windows was unable to restore the GPU from a low-power or idle state.

This failure caused repeated black screen events lasting several seconds, indicating that the GPU could not properly resume operation. All standard and advanced software-level troubleshooting steps were attempted, but the issue persisted, clearly requiring deeper technical diagnosis and hardware-level intervention.

Due to this condition, the Lenovo Legion 5 15AKP10 became unavailable for primary operational tasks.

Service Center Diagnosis & Repair Process

On 2 December 2025, the device was brought to an official Lenovo Service Center, where I explained the issue in detail to the technician (Novi), including my own technical analysis. After evaluation, Lenovo confirmed that the repair process would require approximately three days, with an estimated completion date of 5 December 2025.

During this period, UMC operations were temporarily suspended until the repair was finalized.

Following a comprehensive hardware diagnostic and full system scan, Lenovo technicians identified the root cause:

A silicon-level defect in the integrated GPU (iGPU) within the APU

The failure originated from a power-gating logic transistor, preventing the iGPU from waking correctly from low-power states

This defect directly caused the recurring black screen behavior and unrecoverable TDR events

As a result, the entire mainboard was replaced with a new unit using the same official FRU (Field Replaceable Unit) part number, ensuring full compatibility and factory specifications.

Warranty Status

Fortunately, the device remains fully covered under Lenovo Legion Ultimate Support, valid until 17 November 2028. The entire repair, including the mainboard replacement, was completed under warranty.

Repair Completion Updates

Update — 5 December 2025:

The repair process was successfully completed, and the device was declared ready for return from service.

Update — 16 January 2026 (Edited):

Further confirmation identified the issue conclusively as a silicon defect in the iGPU inside the APU, validating the original hardware diagnosis.

Issue date: 30/07/2025  Updated : 31/07/2025  Note:  We updated with example of LNV -5B10W13897 batteries. (Update: UMC officially designated as L17C3PS2.) UMC ID: UMC01-07042   UMC today announced that was issued formal advisory that would recall of current fleet laptops is Lenovo ThinkPad L15 Gen 2a was equipped with Celxpert batteries because that degradation trend was flaw , lasting only 3+ hour battery life as observed. Key findings were included in screenshots. Figure 1: A degradation trend from 45.73Wh to 38.39Wh in Commercial Vantage. Multiple complaints from Reddit users raised concerns over the Celxpert batteries because they degrade into 16% wear level based on observations from linux-hardware.org sites that used to lookup for battery models and concluded that Celxpert (e.g,  LNV-5B10W13897  (L17C3PS2 detected) batteries) was worst long-term retention of advertised watt-hours.

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...

UMC Bans the DeepSeek amid security concerns

-
 We are announcing the UMC now starting to ban the DeepSeek due to amid security concerns. The DeepSeek is a Chinese AI was developed by  Hangzhou DeepSeek Artificial Intelligence Basic Technology Research Co., Ltd. that doing business created the AI models is a thing dangerous. And the UMC banned the DeepSeek for employee using dangerous AI models that expose the personal and company information could potentially leak and vulnerable attacks that penetrated for my studio UMC Corporation. We advise to not use DeepSeek AI for security reasons. We appreciate this take serious action by UMC officials at representative from using Chinese AI apps.
