La-e801p Rev 2.0 Schematic ❲FRESH ✦❳
The LA-E801P Rev 2.0 Go to product viewer dialog for this item.
- Step 1 – Visual: Check for corrosion near PU2 (BQ24735) or PQ30/31. This is a common failure.
- Step 2 – Measure: Find
DC_IN(page 4 of schematic). Verify 19V at drain of PQ30. - Step 3 – Check ACDET: On PU2, pin 5 (ACDET) should be ~2.6V (via resistor divider PR33/PR34). If not, charger IC won't turn on.
- Step 4 – Check REGN: PU2 pin 16 (REGN) = 6V. If missing, replace PU2.
- Step 1 – Check all coils: Find
PL4(+5V),PL5(+3.3V),PL9(Vcore),PL12(1.05V). Use boardview to locate them. - Step 2 – Check PCH power: Look for
+1.05V_PCH(page 20). If missing, check PU7 enable pin (SUS_ONfrom EC). - Step 3 – SPI BIOS: PCH requires SPI flash to boot. Check
SPI_CS#(page 37) for activity with an oscilloscope. If stuck high, EC isn't releasing reset. - Step 4 – LCD connector:
LCD_VCC(page 29) = 3.3V only when backlight is on.DISP_ONcomes from EC.
USB-C / Charging Circuit: Since this board relies on USB-C for power, the CC lines and the USB-C Controller chip are high-stress areas. If the laptop won't charge, check the protection diodes near the USB-C port. la-e801p rev 2.0 schematic
