  Published on UMC Blogger Official Overview During an active testing session, our team conducted a deep investigation into unexpected behavior observed in Lenovo's WMI GameZone interface and the custom boot logo functionality within the Lenovo Legion Toolkit (LLT). This report summarizes the findings, root causes, and pending action items identified throughout the session. Background Testing began with the deployment of test1.ps1  a diagnostic script targeting the root\WMI namespace — specifically the LENOVO_GAMEZONE_DATA class. The script operates in safe mode, meaning it only invokes Get/Is methods that require no [In] parameters, to protect system integrity during automated testing. Initial output from the script returned minimal results, causing confusion among the team. At this stage, the root cause was not yet identified. Finding 1 — WMI Method Parameter Requirement After testing on a 2025 Legion 5 15AKP10 running Windows PowerShell ISE as administrator, ...

 United Metrolite Central (UMC) will temporarily suspend all battery systems made by Sunwoda Electronic because of the escalating patent dispute started by LG Energy Solution. This includes all Sunwoda-integrated systems that UMC monitors. One retired unit of the Lenovo IdeaPad Gaming 3 15ACH6, which has a Sunwoda battery, is now classified under restricted status. The suspension is a precaution and is based on ongoing legal and regulatory issues, including investigations by the Korea Trade Commission. No safety defect has been confirmed. This step is only due to legal uncertainty and possible effects on battery supply chains. The directive will remain in place until the dispute is resolved and related regulatory decisions are made.

At CES 2025 , Lenovo unveiled its 2025 lineup, including the new Legion 5 Gen 10, Legion Pro 7i, and the handheld Legion Go 2. I followed the announcements online, already considering an upgrade. Before July 2025, I had planned to replace my IdeaPad Gaming 3 15ACH6, which was starting to struggle with newer AAA titles. My initial target was to purchase the Legion 5 Gen 10 on August 17, 2025. However, those plans were delayed until November 17, 2025 due to security concerns and industry-wide turbulence surrounding critical BIOS/UEFI vulnerabilities. Eventually, my United Metrolite Central (UMC) acquired a Legion 5 Gen 10 (model 15AKP10, 2025) on November 16, 2025, and I picked it up the following day. This decision came after a selection process to find a device that could balance both gaming performance and work needs. Originally, we aimed to secure a Legion 7i, but it was out of stock. As a result, the Legion 5 became the final choice—and ultimately, the system I moved forward wit...

 Per EU law (EU Batteries Regulation (2023/1542), Article 11), United Metrolite Central updated for all models including Microvision II Advanced Console (mainstream), Microvision X nano (rugged version), and Microvision II ZSX (high-performance by Zyrus) to comply with EU law requirements that have removable batteries and no lock-in battery firmware, just simple with Battery Safety Monitoring System (BSMS) module, allowing third-party battery to meet the all safety critieria. These projects are ongoing and expected to follow rugged and standard models depending on SKU model. The X nano RB (Removable Battery) is planned.

 The NVIDIA N1X was rumored and scheduled to launch in H1 2026, the original release date was pushed back to 2026 after 2025 delay due to redesign and several mismatches. Lenovo accidentally leaked the Legion Space with support was " Legion 7 15N1X11 ", and later leaked new Yoga with N1X was " Yoga 9 2-in-1 16N1X11 ". Deployment of one unit is scheduled within same date is H1 2026 for United Metrolite to replace the L15 Gen 2 first via United Metrolite Central Network Service Deployment Unit (UMCNSDU) built-in in HQ. UMCNSDU will deploy the one unit for work and gaming with N1X is planned at date (Q1 2026 or H1 2026). We committed to use the script to check the readiness deployment which provided by service networks.

 UMC announced that the United Metrolite Central Battery Procedure Checklist is no longer drafted and now available converted from PDF to text in the web.

 UMC announced that fleet will be supported for lifecycle fleet until at least November 31, 2028 after purchased back at date February 9, 2025. This aligns with Lenovo PSREF's End of Support is December 4, 2030 date for Legion Go S 8ARP1. UMC will be re-platforming the entire fleet with partial AI PCs to ensure stability within fleets across managed systems. UMC developed by one-person developer for my script is "ThinkPad Utility Management" (TUM), a PowerShell-based code. Update: The future of Legion Go S will be replaced within Yoga 9 2-in-1 16N1X11.

 After purchase on May 13, 2025 of used ThinkPad L15 Gen 2a, UMC announced that would end of service starting in March 15, 2027 and will be moved to new Yoga 9 2-in-1 16N1X11. This new model is powered by NVIDIA N1X, UMC is committed to ensure the updates are necessary. Based on Lenovo PSREF, the End of Support date is December 2027, its 9 months away after UMC ended before Lenovo ended their model of L15 Gen 2a. At the time, UMC will no longer in service after this date. Yoga 9 2-in-1 16N1X11 was tailored for productivity and gaming. This is major leap from this my older L15 Gen 2a model. We will continue to receive repair fixes and maintenance annually.

 United Metrolite Central announced that would reconsider the Role of Deployments now has several changes for the current role to new current role. This matches for the UMC deployment needs. This is a list of new changes will take effect in Q2 2026: ThinkPad L15 Gen 2a : Backup machine deployments with new my script " ThinkPad Utility Management " (TUM). Legion 5 15AKP10 : Primary machine deployments. Legion Go S 8ARP1 : Secondary machine deployments. Custom-built desktops : Third and backup machine deployments. This aligns with new broader changes for UMC strategy deployments in the managed environments. These deployments help make smoother and faster workflow environments in the managed that currently owned by a single-dev UMC center.

 United Metrolite Central released a statement regarding about battery supplier for cell battery manufacturers. While we working on prototype, UMC has restricted the cell supplier, Zhuhai CosMX in Germany for planned release Microvision II and Microvision X nano after Court Munich found that ATL patent is enforcable and ruled out where ATL won the 2024 Munich infringement ruling until appealed when hearing is scheduled Higher Regional Court by March 2026. Our UMC team is taking serious action and penalize if CosMX illegally imported battery to the Germany under injunction law. The UMC Enforcement is on standby and if found, we take action. The UMC selects high-quality from cell supplier such as U.S., China, Taiwan, and Korea for better quality and reliable.

 During regular maintenance period, United Metrolite Central noticed that our own used ThinkPad L15 Gen 2a had thermal issues. UMC is investigating the root cause and comfirmed that found the issue was heat leak coming from SSD that no thermal pad installed. Since Lenovo removed the SSD thermal pad in many special-bid / fleet configuration, leaving NVMe with no proper heat path. This affects PCB motherboard and the battery zone (third-party battery installed on August 2025) caused by heat leak that NVMe couldn't cool down properly with expected at 64 °C max temperature for drive. UMC is working to resolve the heat leak issue by adding for thermal pad to reduce the warm temperature to cooled temperature. This best method is 1.0mm thickness of thermal pad is recommended to apply for L15 Gen 2a. UMC is looking the temperature for battery and drive via HWiNFO and Lenovo Vantage. Update on March 4, 2026 : The Thermal issue was fixed with CPU thermal repaste. The operation was returned.

     A long history of the Microvision, a first console with interchangeable catridge was launched by Milton Bradley in 1979. However, its small game library, its small screen, and a lack of support from established home video game companies led to its discontinuation in 1981. In this personal project, I revived the original Microvision with new modern project, called Microvision II (codename: Hawk Regine), a new modern look and repairable compliant with EU's 2027 Right to Repair. With new advanced features and designs look thinner than the original Microvision, this led to work for concept designs that drawn on paper by date in 2024. My original concept of planned to design from hand-drawn paper about concept of Microvision II (known as Microvision II Advanced Console) and X nano within advert-style based designs. A Microvision II concept design work art from 2024 Microvision X nano concept art from same year as 2024 With first to integrate with my own proprietary is Hey...

 In a short amount of time, lithium-ion batteries are now how a lot of us are storing energy in our devices like phones, laptops, and wearable tech. As the demand for tech grows, so does the global supply of lithium-ion batteries struggle to keep up. After lithium prices had corrected themselves in 2023 - 2024, they are now rising due to a strong electric vehicle market, increased use of solar energy storage, and new AI datacenter. This renewed upward pressure on lithium prices has significant downstream implications—not only for automotive and industrial battery applications, but also for the often-overlooked replacement battery market for personal computing devices. The Rise of the Lithium Prices After 2024 - 2025 lithium prices collapsed ~90% in 2023–2024 due to oversupply, the prices are growing again by 2025 - 2026 lithium prices are soaring ~130% from 2025 by late 2025, report data sources from Reuters . They're shrinking the lithium supply like Dongguan NVT Technology (Dong...

In response of ongoing increase in lithium battery price, it has been decided to keep using the third-party battery that is currently installed in the ThinkPad L15 Gen 2 due to the continuous rise in lithium battery component prices that are impacting both OEM and third-party suppliers. The goal of this measure is to lessen exposure to market volatility associated with lithium supply constraints and to mitigate higher replacement costs. Currently, UMC will continue to monitor as possible to watch both genuine and third-party batteries. This applies to our safety standards of procedures in the United Metrolite Central policies. We have regret of price increase as battery packs, UMC will have no responsibility for property damage, injury, or other accidents. Stay Safe and Stay Vigilant!

  The real story behind Lenovo Legion Toolkit Issue #162 On January 15, 2026 , a GitHub issue was opened on the Lenovo Legion Toolkit repository by ScripterRickster . At first glance, it looked like a typical RGB bug: the keyboard lighting preview was broken, zones were missing, and the UI didn’t resemble the physical keyboard. But the truth turned out to be much deeper — and much simpler. This is the story of how a code check didn’t fail, yet still got everything wrong . The Symptom: A Broken RGB Keyboard Interface Users reported that: Only a few areas of the keyboard reacted to RGB changes The preview showed a strange horizontal strip instead of a full keyboard Lighting effects looked inconsistent or “random” Importantly, the application did not crash . Everything appeared to load normally — which made the issue harder to diagnose. The Initial Assumption: “The Check Passed” From a developer perspective, the toolkit had already passed its internal validation:...
