XPS 15 turns off when adapter is plugged in

Asked By 60 points N/A Posted on -

I have a new XPS 15 and suddenly it started having problems. The laptop turns off whenever I plug in the adapter. It worked fine with the battery, but as expected, it didn't last long since the battery drained out. The light on the power adapter is always on so I can tell it's fine. What do you think is the problem? Is this something I can fix on my own or I should just call tech support?

The battery and the laptop work fine. The adapter is the problem.

Laptop adapters offer an output of 19.5 to 22 Volts at 4.6 or 5 Amperes. Every laptop motherboard has a resistive protection that cancels any kind of high voltages or currents that start to travel through the circuit.

This automatically sends a signal that shutdown any components, thus leaving your laptop unwilling to power on until the necessary input voltage is received.

However, do not plug in the AC adapter anymore. It might be an AC rectifier inside that is faulty it doesn't convert the alternative current to direct current, as it's necessary for the laptop to function properly.

I recommend in buying a new AC adapter because there is no point in fixing the one you have right now. It might cost you less if you repair it, but you don't know if it will function properly. Find an AC adapter for the same laptop model with the same specifications.
