Appendix B. Troubleshooting
Before contacting Service and Support, complete these steps to verify if your
adapter is defective:
1. Inspect your adapter.
a. Inspect case for any damage (for example, cracks, deformations, or
exposure to water).
b. Inspect cables for any damage (for example, cracks, cut, or exposed
wiring).
c. If any damage is found, discontinue use of the adapter and contact
Service and Support for replacement parts.
2. Ensure all of the connectors are firmly seated at the power receptacle, the
input side of adapter, and the notebook computer.
3. Ensure the adapter has adequate ventilation. The adapter might overheat
and shut down if it is operated too long in a confined area.
4. Check the AC receptacle by connecting a known working device (for
example, a lamp). If the AC receptacle is not working, verify that your
circuit breaker or fuse panel.
5. Connect the adapter to your notebook computer:
a. If the adapter immediately shuts off, check your notebook computer
connector for looseness or damage. Try connecting the original AC
adapter to your notebook computer. If the original AC adapter operates
correctly, contact Service and Support for a replacement adapter.
b. If the adapter works for a period of time and then shuts off, check to
ensure that the adapter has proper ventilation. It is normal for the
adapter to feel warm when you touch it.
Note: The adapter is designed to shut down and latch off when a fault is
detected. The fault must be removed AND the adapter must be disconnected
for at least 10 seconds before you can reset the adapter.
