La-f952p Schematic ((free)) Online

The Compal LA-F952P (also known by its project code NB8610) is a highly prevalent motherboard found in the Lenovo IdeaPad 330 series, specifically the 330-15IKB and 330-17IKB variants. Powering 8th Generation Intel Core processors (Kaby Lake R) paired with AMD Radeon discrete graphics or Intel UHD integrated graphics, this board is a staple on repair benches worldwide.

If the laptop powers on but fails to show an image, the problem lies in the display initialization or memory rails.

What have you already taken on the main power rails? Do you have access to a multimeter or an oscilloscope ?

Built for Intel Coffee Lake-H series processors (such as the Core i7-8750H or i5-8300H) coupled with dual-channel DDR4 memory slots. la-f952p schematic

Commonly marked as PR8107 or similar depending on the exact sub-revision. This monitors overall current draw to safeguard against catastrophic over-current spikes. 2. Standby Power Rails ( +3VALW and +5VALW )

Locate the power jack page on the schematic to identify the first input components, usually protection diodes and dual MOSFETs (e.g., PQ301 , PQ302 ).

Look closely at the schematic for open trace breaks denoted by symbols like PJ1 or PJ301 (Power Jumpers). These are small solder pads bridged together at the factory. If you have a short circuit on the 3.3V rail, you can desolder and split open the PJ jumper. This immediately isolates whether the short lies on the producing side (the PWM regulator IC) or the consuming side (the PCH, IO chips, or audio codecs). The Compal LA-F952P (also known by its project

Look for "Compal LA-F951P LA-F952P" or "DH5VF" files. These are often shared in electronics repair forums.
