Typically integrates Intel Core i3-6100U , i5-6200U , or i7-6500U . Memory: Utilizes DDR3L RAM (Low Voltage).
If you're interested in obtaining the ASL50 LAC921P Rev 10 schematic, here are a few possible ways to acquire it:
(Always-On Rails): These are produced by the main PWM controller. Without these, the laptop will not turn on. +3VSUSpositive 3 cap V sub cap S cap U cap S +5VSUSpositive 5 cap V sub cap S cap U cap S (Suspend Rails): Active after the power button is pressed. asl50 lac921p rev 10 schematic exclusive
The ASL50 LA-C921P is an OEM motherboard manufactured by Compal Electronics. Revision 1.0 represents the initial production baseline for this specific architecture. Understanding the core specifications helps isolate whether a fault lies within integrated chipsets or peripheral power rails. ASL50 LA-C921P Revision: 1.0
An schematic implies that this rendition contains manufacturer annotations, test point voltages, and component-level troubleshooting notes not found in generic datasheets. Typically integrates Intel Core i3-6100U , i5-6200U ,
| Method | Likelihood | Notes | |--------|------------|-------| | Lenovo service center | High (but restricted) | Only for authorized repair | | Paid repair sites (e.g. Badcaps.net, Vinafix) | Medium | Members sometimes share boardviews/schematics | | Public Google/forum search (board number in quotes) | Low | Most links are dead or malware | | Reverse engineering from board | Very low | Requires removing soldermask and tracing by hand |
A shorted CPU buck converter MOSFET can pull down the entire system instantly to protect components from overvoltage. Without these, the laptop will not turn on
Damaged protection diodes or direct damage to the Southbridge component within the CPU. Understanding the Schematic Sections (LA-C921P) The schematic is typically divided into functional blocks: 1. Power Supply Circuitry Go to product viewer dialog for this item. uses specialized DC-DC controllers for voltage regulation. 19V19 cap V VINcap V cap I cap N ): Input voltage protection. 3.3V3.3 cap V Standby: Provided by PU301cap P cap U 301 . These must be present before the laptop powers on. : CPU Power. 2. Clock and Reset Lines : Signals that the power supply is stable. : Platform Reset. 3. BIOS and EC (Embedded Controller)
The entry point of the 19V rail uses dual N-channel MOSFETs (typically AO4407A or similar) to isolate the DC-in jack from the main system rail ( B+ ).
