Customer's dell laptop is very picky when it comes to turning on. Most of the time when the power button is pressed, amber light comes on. Feel like the power button was meant to turn the amber light and not the laptop LOL. Any advice where I should start? Motherboard? Rumor has it a defective battery can destroy the motherboard circuit.

Okay, let's find out... First, measure the standby-current of the laptop, is there any current consumption without starting the device? Then, is there any change in current consumption if you press the power button?
Now open the device. Do not power it. Carefully measure the voltage at the battery. Is the battery dead?
