Alpha and Omega Semiconductor AO4435 datasheet, a 196 KB PDF; the extra number in the name only marks a duplicate save. The AO4435 is a P-channel MOSFET in an SO-8 package, frequently used as a load or input switch on laptop power paths. The document covers pin assignments, threshold voltage, on-resistance and thermal limits. During repair it helps identify which pins are source, gate and drain so you can check for a short on the adapter or battery path and select a proper replacement.
