Yes. Dell computers provides technical support. They provide specific types however. They provide "hardware" fault diagnosis and repair service.
Not necessarily. There could be different components at fault when your laptop fails to charge properly - the power supply (power brick), the charging circuitry inside the laptop for the battery, and/or the battery itself (which in itself also has a circuit for diagnosis, telemetry [battery level, battery health], and overcharge protection).
When they develop a fault.
The problem's activity.
A diagnosis is for an illness or a fault. It is not a component of a driving exam.
chicken dippers!
In cases like this it is best to use an anolog meter instead of a digital meter,I say one of your switches is bad, rarely is it both switches,if the wiring has not been tampered with, the switch is breaking the contact to the light when the door is closed,when the door or doors are opened current or volts flows. sometimes a digital meter is to fast to detect the fault, current is leaking by one of the switches. disconnect the battery, or remove the bulbs until the problem is solved.
Clean the switches and check that the harness on the switches is tight, its usually just the power seat ajustment switches that are at fault and not the seat at all.
You could have a fault in the battery or even a short if so replace the battery
Describe the specific safety precautions to be taken when carrying out fault diagnosis of the specific piece of equipment
on my old 1.2 clio the battery light came on as there was fault with the alternator and it needed replacing. As far as i know the battery light comes on when the battery is not charging or there is a fault with the battery.
Possibly a technical fault.
