: Check for the "Always On" voltages required for the power button to function.
A motherboard schematic is essential for "chip-level" repair. If your laptop is "dead" or not charging, the schematic helps you trace power rails: ya-4a194v-0 motherboard schematic

The is a specific motherboard marking often found in a variety of laptop models from manufacturers like Asus , Lenovo , and Acer . Because this number refers to the printed circuit board (PCB) raw material standard (E114139) rather than a unique laptop model, finding the correct schematic requires identifying the actual "Platform Name" or "Mainboard Model" usually printed near the RAM slots or under the stickers.
