La-g121p Schematic Access

Dell laptops are notorious for charging issues or "Plugged in, not charging" errors. The LA-G121P schematic details the charging IC (often an Intersil/Renesas chip). You can verify if the PS_ID signal—the signal from the center pin of the Dell power adapter—is reaching the Super I/O chip (KBC). 4. The Voltage Rails Table

Always remove the battery and AC adapter before probing the motherboard with a multimeter to avoid accidental shorts. Dell laptops are notorious for charging issues or

If your power brick light goes out when you plug it in, you have a short on the main 19V rail ( B+ ). The schematic helps you isolate which power stage (CPU, GPU, or WiFi) is pulling the voltage down. The schematic helps you isolate which power stage
