La-7912p Rev 1.0 Boardview May 2026

Overview: LA-7912P Rev 1.0

• +RTC_CELL: Powers the CMOS real-time clock.
• +VIN (B+): Main DC input (19V to 20V). Enters through the DC jack and protection MOSFETs (typically PQ301/PQ302).
• +3VPCU / +5VPCU: The "always-on" linear or PWM rails generated by the TPS51125 (PU401) or similar. These are the first rails to appear when the adapter is plugged in.

• Type: DDR4 or DDR5 RAM support.
• Slots: Number of DIMM slots and maximum RAM capacity.
• Speed: Supported RAM speeds (e.g., 3200MHz, 3600MHz).
