說明

The AC adapter of Dell systems can get damaged due to accidental damage or improper usage. The damage can occur on the AC adapter brick, AC adapter cable, or power cable.

If the AC adapter or the cables are damaged, frayed, exposed, or have broken or bent pins, it can stop the computer from powering on or charging the battery.

WARNING: A damaged, frayed, or exposed AC adapter or power cable can cause an electric shock. Do not touch the damaged, frayed, or exposed part or the AC adapter or cables. Power off the main wall outlet immediately.

The AC adapter or the cables can get damaged due to improper handling, incorrectly wrapping the cords, disconnecting the cables by pulling on the cord instead of holding the plug, and so on.

AC adapter or the cable can get damaged in differently.

NOTE: Normal wear and tear are not covered under the warranty of the Dell product.

Frayed Cables

NOTE: Normal wear and tear are not covered under the warranty of the Dell product.

Cables can get frayed at either end of the AC adapter cable that comes from the AC adapter brick to the DC-in power port on the computer or the power cable.

This issue may occur if the cable is subjected to undue stress by incorrectly wrapping the cable, wrapping the cable too tightly, or cable twists.

Exposed Wires

NOTE: Normal wear and tear are not covered under the warranty of the Dell product.

If the cable is frayed or cut in any way, this may expose one or more internal wires. If the cable is frayed or cut, or any of the internal wires are exposed, you must immediately discontinue using the AC adapter.

Cut in Cable

NOTE: Normal wear and tear are not covered under the warranty of the Dell product.

A cut in the cable may appear at the flexible joints near the adapter brick or the connector. These flexible joints are designed to allow the cable to bend when being wrapped around the adapter brick, but over time the cable can become brittle and cuts may appear. A cut may also appear if the cable is rubbing against the edge of an object, like a desk or chair.

Pin that is bent or broken

NOTE: Normal wear and tear are not covered under the warranty of the Dell product.

The adapter pin may become bent or break entirely if it is not plugged into the DC-in power port of the computer correctly. Removing or inserting the cable at an angle or forcing an incorrect AC adapter may cause the center pin of the adapter or the DC-in power port to become bent or broken.

Cable Loose and Open AC Adapter

NOTE: Normal wear and tear are not covered under the warranty of the Dell product.

If you have a cable that is loose, try disconnecting the cable and reconnecting it. Ensure it is firmly connected. If the cable continues to be loose, check for bent or broken pins or damage to the connector on the computer or the cable.

If there is damage to the cable that is causing the issue, the adapter and or cable must be replaced. Contact Dell Technical Support for repair options that are available in your region.

WARNING: When you disconnect the AC adapter cable from the computer, hold the connector or plug. Do not hold the cable. This can cause irreparable damage to the cable or the connector on the computer. Dell AC adapters are rated to work with all electrical outlets worldwide. However, power connectors and power strips vary between different regions. Using an incompatible cable or improperly connecting the cable to the power strip or an electrical outlet may cause fire or damage to the equipment.

CAUTION: Do not attempt to open, repair, change, or test any part of an AC adapter, as this may cause injury or even death.
