Replacement AC adapter for Satellite PRO U400

This 75 W AC/DC adapter replaces the original Toshiba PA3715U-1ACA charger for Satellite PRO U400-SP2804 and U400-SP2908R notebooks. It accepts worldwide 100-240 VAC input at 50/60 Hz and includes a 10 ft power cord for flexible placement. Buyers needing a different connector or higher wattage should look elsewhere.

Thermals noise and power draw

The unit delivers 75 W continuous output with built-in over-current, over-voltage, short-circuit and total-power protection. A smart chip provides overheating protection while high-quality wires and isolation materials reduce interference during normal operation. No active cooling fan is present so the adapter runs silently.

Deciding specification

The critical figure is the 75 W output rating matched to the PA3715U-1ACA part number for the listed Satellite PRO models. Certifications include FCC, CE and RoHS confirming compliance with safety and environmental standards. Compatibility is limited to the U400-SP2804 and U400-SP2908R series identified in the product data.

Questions about this item

How do I connect the 10 ft power cord to the U400-SP2804 without strain?

Plug the barrel tip firmly into the laptop DC jack first, then route the 10 ft cord away from foot traffic before connecting the IEC C7 mains lead to the adapter brick and the wall outlet.

Which parts of the 75 W adapter will need replacement after extended use?

The detachable mains cable and the barrel-tip DC cord are the only field-replaceable items; the sealed brick contains the smart chip, overload and short-circuit protection and is not user-serviceable.

At what sustained load does the 100-240 VAC input protection engage?

The over-current and total-power protection circuits trigger when continuous draw exceeds the rated 75 W output, limiting the adapter before overheating protection activates.
