E82152 Schematic: 2021

: The marking on your board signifies that the bare PCB meets UL safety standards for flammability and manufacturing quality.

In older schematics, the current sense shunt (R25) was on the high side (+24V rail). In the , R25 (0.01Ω, 3W) has been moved to the low side (between load and GND). This allows the LM2902 to measure current without requiring a level-shifter. Consequence: The output load can no longer share an external ground with the control logic.

If you want, I can:

ASUS laptop schematics are usually well‑organized and follow a consistent layout. Here is what to look for:

When searching for a replacement board, do not rely solely on "E82152". The most accurate way to ensure compatibility is to use your laptop's full model number (e.g., "ASUS ZenBook UX360CA") and the part number (P/N) , which is usually printed on a sticker or directly on the PCB silkscreen.

When you see "E82152" printed on a green or blue circuit board, it is often a UL Mark indicating that the board was manufactured by . Manufacturer: Gold Circuit Electronics Ltd (GCE). : The marking on your board signifies that

The E82152 marking appears on a variety of ASUS laptop sub‑boards—power cards, touch controllers, and I/O boards. While there is no single “E82152 schematic,” you can successfully locate the correct documentation by identifying the laptop model and board revision, then searching for the full service guide or boardview files for that model. Once you have the schematic (and a boardview file), diagnosing USB, audio, or power failures becomes a straightforward process of checking voltages, continuity, and component behaviour.

Board short-circuits immediately when power supply is connected. Texas Instruments or Cypress Power Delivery chips This allows the LM2902 to measure current without
