The Lenovo IdeaPad 100-15IBY motherboard is a proprietary system board with an integrated (soldered) low-power Intel Bay Trail-M or Braswell processor and supports DDR3L SDRAM. The CPU is permanently affixed via a BGA (Ball Grid Array) socket, meaning it is not a removable component. 

Core Specifications

  • Processor: Features an on-board, non-upgradable Intel processor, typically from the Bay Trail-M series (e.g., Intel Celeron N2840, N2940) or Braswell series (e.g., Intel Pentium N3540). These are very low-power, integrated CPUs.
  • RAM: The motherboard design typically features soldered RAM (usually 2 GB or 4 GB) and no additional SO-DIMM expansion slot. The memory configuration is fixed.
    • Maximum Capacity: The total system memory is limited to the soldered amount (typically 2 GB or 4 GB).
    • Speed: Memory operates at speeds up to 1333 MHz or 1600 MHz, depending on the CPU.
  • Graphics: Comes with integrated Intel HD Graphics, which is part of the system-on-chip (SoC) design and utilizes shared system memory. 

Expansion and Connectivity

  • Storage: Includes a standard 2.5-inch SATA II or SATA III interface for an HDD or SSD. It also has an internal SATA interface for an optical drive (DVD-RW).
  • I/O Ports: Provides various soldered ports, including:
    • USB: One USB 3.0 port and one USB 2.0 port.
    • Video: One HDMI port.
    • Networking: An RJ-45 Ethernet port (10/100 Mbps).
    • Audio: A 3.5mm headphone/microphone combo jack.
  • Wireless: Features a dedicated slot (often M.2 or Mini PCIe) for a wireless module, supporting basic Wi-Fi (e.g., 802.11 b/g/n) and Bluetooth options. 

Key Part Numbers

When purchasing a replacement, verify the Manufacturer Part Number (MPN) or the board identifier to ensure it matches the specific processor variant: 
  • 5B20J35481 (example MPN for N3540 CPU)
  • 5B20J35482
  • NM-A681 (board identifier)
