170 W AC adapter for LITEON laptops

This 20 V 8.5 A power supply delivers 170 W through a 7.4 x 5.0 mm barrel connector. It matches the PA-1171-72 specification for compatible LITEON notebook models. Buyers who need a different voltage, tip size or wattage should verify their original charger label before ordering. The unit replaces a lost or damaged factory adapter for supported devices.

Thermals noise and power draw

The adapter operates at its rated 170 W output using standard AC input. No active cooling fan is fitted, so operation is silent under normal load. The external enclosure dissipates heat passively during charging sessions. Continuous full-load use will warm the case to a level typical for high-wattage laptop bricks.

Questions about this item

How do I connect the 7.4x5.0mm barrel plug to my LITEON laptop and what step is often missed?

Align the centre pin and outer sleeve of the 7.4 mm by 5.0 mm connector with the laptop's DC jack, push straight in until it seats firmly, then secure the AC cord to the adapter body so the 20 V 8.5 A supply stays latched.

What part of this 170 W adapter will need replacement first and how can I tell?

The detachable AC mains lead usually fails before the brick; replace it when the plug shows cracked insulation or the connector feels loose on the PA-1171-72 unit.
