Common Repair Examples (concise)

• No power, short on 3.3V: Locate shorted LDO output — remove nearby electrolytic and tantalum caps, then isolate PMIC.
• No display but boots: Check eDP/LVDS power rails and display power sequencing; verify GPU Vcore and 1.2V/1.8V rails.
• Battery not charging: Test charger presence at DC jack, check charging FETs, measure SMBus signals to battery and PMIC.
