When troubleshooting a "no power" state on the GS44B, the first step is verifying the . Based on the NM-C561 architecture, you should check the following rails in order:
Verify if the 19V input is reaching the PJ 5301 jumper.
If you are working with battery packs for power tools, flashlights, or DIY power walls, you have likely encountered the , 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.

Once all regulators confirm their output voltages are stable, a Power Good signal is aggregated and sent back to the processor to release the system reset lines. 4. Common Failure Modes on the NM-C561
The is a motherboard developed by LC Future Center (LCFC) for Lenovo. It is designed to support Intel Core processors and is used in budget-friendly yet capable laptops like the Lenovo IdeaPad S145-15IKB. Key Technical Specifications: Motherboard Platform: LCFC NM-C561. Board ID/Number: GS44B / GS54B / GS44C / GS54C. CPU: Intel Kaby Lake-U/R processors. Memory: DDR4 SODIMM slots.
Even when off, the board has "Always On" voltages that can short out if your probe slips. When troubleshooting a "no power" state on the
Understanding the power-on sequence is key to troubleshooting a "no power" issue on the . If the sequence stops, the laptop will not start.
Clock: verify crystal oscillation on oscillator pins; replace suspect crystal or caps.
