Intel Celeron M 440 Mobile Processor (Socket M) – Single-Core CPU for Legacy Laptops (SL9KW)
Are you looking for a reliable replacement part to rescue an old laptop running specialized corporate applications under Windows XP, or are you repairing vintage computing hardware? The mobile single-core Intel Celeron M 440 processor (S-Spec SL9KW), built on the 65nm Yonah architecture, is exactly what you need to revitalize portable computers from the 2006–2007 era.
This processor features a single physical core operating at a clock speed of 1.86 GHz. With a 1 MB L2 Cache and a fast 533 MHz FSB, it provides stable and predictable performance for older 32-bit operating systems and basic office applications. With a thermal design power (TDP) of just 27W, it is ideal for maintaining the quiet operation of the original laptop cooling system.
Key Features of the Intel Celeron M 440 Processor
- 1 physical core running at a frequency of 1.86 GHz.
- Generous 1 MB L2 Cache for legacy application workloads.
- Standard system bus with a **533 MHz FSB**.
- Proven 65nm manufacturing technology (Yonah core) with a low 27W TDP.
- 32-bit (x86) architecture ensuring full compatibility with older software.
- Designed for laptop motherboards equipped with the Socket M (mPGA478MT) interface.
Ideal for Windows XP and Diagnostic Workstations
Even today, this type of processor remains highly relevant for workshop laptops dedicated to automotive diagnostics, controlling older CNC machinery, or working in service environments where modern 64-bit systems conflict with legacy software. It guarantees 100% native execution of 32-bit code exactly as older applications require.
Compatibility and Socket
This mobile processor is designed exclusively for the **Socket M** interface (code mPGA478MT), which is typically found on motherboards based on the **Intel 940GML, 945GM, or 945PM** chipsets. Although the socket has 478 pins, it is NOT electrically or physically compatible with the desktop Socket 478 nor with the newer mobile Socket P.
