Lah103p Schematic New [2021] -

Check the first and second input MOSFETs right after the DC jack connector. High-side MOSFETs feeding the CPU core or GPU phases frequently short to ground, transferring 19V directly to low-voltage lines. Corrupted Bios or EC Firmware

Here is what you need to know about locating the new schematic and how to work around the lack of official documentation. lah103p schematic new

Once the power button is pressed, the EC releases the standby signals, prompting the board to generate secondary voltages. +1.2V_VDDQ (Powers the DDR4 RAM). Chipset Rail: +1.8VALW and VDDCR (AMD SOC core voltages). 5. CPU & GPU Core Rails (VCORE) Check the first and second input MOSFETs right
