Gs44b Gs54b Nm-c561 Schematic 【HIGH-QUALITY】
Before downloading files, you must understand the hierarchy of these codes.
Critical Warning: Do not mix boardviews. While the NM-C561 schematic covers the PCH (Platform Controller Hub), CPU power delivery, and I/O logic for both, the GS44B and GS54B have drastically different power sequencing around the GPU area. Using the wrong boardview will lead you to test empty pads.
Once you have the schematic open (reference sheets 5 through 12), pay attention to the following common failure zones:
The GS44B, GS54B, and NM-C561 are standard 5S Li-Ion battery assemblies. While official printed schematics are rare, their internal topology
GS44B/GS54B NM-C561 is a motherboard schematic and boardview reference for the Lenovo IdeaPad S145-15IKB laptop. Manufactured by LC Future Center (LCFC)
, this board is a common platform for mid-range IdeaPad models released around 2019. Technical Specifications & Core Architecture The NM-C561 motherboard is designed to support both Intel Kaby Lake-U (7th Gen) Kaby Lake-R (8th Gen) processor series. Chipset/CPU: Intel KBL-U22/U42. Integrated Available in both (Integrated) and
(Discrete) configurations. The discrete models typically use NVIDIA GeForce MX110/MX230 (N16S-GTR/N17S-G1) with GDDR5 memory. Embedded Controller (EC): Managed by the ITE IT8586E Connectivity: Includes SATA, USB, audio, and LAN interfaces. Essential Repair Resources
For technicians, the schematic and boardview are critical for diagnosing power issues or component failures. Schematic Diagram: gs44b gs54b nm-c561 schematic
A detailed 60+ page PDF mapping all electrical circuits and power rails. Boardview File: Often provided in
format, this allows visual tracing of components like resistors, capacitors, and ICs directly on a digital PCB representation. Power Flow & Sequence:
These diagrams help troubleshoot "No Power" states by showing the step-by-step voltage initiation (e.g., verifying if the input reaches key test points like Where to Find Files

The GS44B/GS54B NM-C561 schematic and boardview files are essential technical documents for repairing the Lenovo IdeaPad S145-15IKB
laptop. These files provide the electrical blueprints needed to troubleshoot power rails, identify faulty components, and trace signal paths on the motherboard. Technical Document Details
The schematic for this specific LCFC motherboard (NM-C561) typically covers: Before downloading files, you must understand the hierarchy
Power Sequence: Detailed diagrams of how the board powers up from the DC jack to the CPU. Voltage Rails: Locations and specifications for +3VALWpositive 3 cap V cap A cap L cap W +5VALWpositive 5 cap V cap A cap L cap W , and CPU core voltages.
Component Map: A boardview file (usually in .brd or .cad format) that allows you to click on a component to see all its connected traces.
Pinouts: Connections for the keyboard, LCD connector, battery, and BIOS chip. Where to Find the Files
Since these are proprietary documents, they are primarily hosted on specialized technician forums and laptop repair databases. You can find the GS44B GS54B NM-C561 schematic on platforms such as:
NotebookSchematics: Offers a direct download for the schematic and boardview set.
BadCaps.net: A popular community forum where technicians often share BIOS dumps and schematics for Lenovo models.
Vinafix: A comprehensive library for mobile and laptop repair files (often requires a subscription). Critical Warning: Do not mix boardviews
If you are currently troubleshooting this board, let me know:
What is the primary symptom (e.g., no power, no display, or water damage)? Which voltage rails have you already measured?
You cannot rely on software to tell you which board you have. Flip the motherboard over. Near the RAM slots or under the M.2 SSD slot, you will see white silkscreen text.
If you are working with battery packs for power tools, flashlights, or DIY power walls, you have likely encountered the GS44B, GS54B, and NM-C561 designations. These are commonly printed on the plastic housing of battery packs used in brands like Parkside (Lidl), Einhell, and other OEM manufacturers.
Because manufacturers rarely release official internal schematics to the public, repurposing these batteries requires understanding the standard layout of Lithium-Ion (Li-Ion) and Lithium Polymer (LiPo) packs.
This guide covers the likely schematic, pinout identification, and how to safely repower these modules.
