## Long description

The Dell 235W Cypher W125711985 replacement AC adapter delivers up to 235 watts of continuous power for compatible Dell systems. It is intended as a direct replacement or spare power supply to restore charging and operation for laptops or small workstations that accept this adapter form factor and output.

How to use
Confirm that the adapter's output specifications and connector type match your system requirements before connecting. With the system powered off, connect the adapter's DC plug to the device's power inlet, then plug the AC cord into a properly grounded mains outlet.

Disconnect the AC mains before removing the adapter from the device, and avoid bending or sharply twisting the cord near the connector to maintain reliable contact.
Usage recommendations
Use this adapter only with compatible Dell systems that accept a 235W external power supply. Operate the adapter in well-ventilated areas and avoid covering it during use to prevent overheating. If the adapter becomes unusually hot, emits odors, or shows visible damage, discontinue use and replace it. For best results, pair the adapter with a battery and system firmware that are up to date and use a properly grounded mains outlet.
