Genuine IBM AC/DC Adapter for Compatible Systems

This genuine IBM 85G6675 power adapter supplies 16V at 4.55A for a total of 72W. It includes a detachable power cord and a round tip connector. The unit accepts worldwide input from 100 to 240V at 50 or 60Hz. It is intended for users replacing a lost or damaged original supply for matching IBM hardware.

Thermal and Electrical Behaviour in Normal Use

The adapter incorporates safeguards against incorrect voltage, short circuit and internal overheating. Each unit is tested for wire integrity, jack function and internal debris before dispatch. Minor cosmetic marks may be present on the casing but do not affect operation. Normal use stays within the rated 2A input and 72W output limits.

Sustained Load Characteristics

Under continuous demand the adapter maintains its 16V 4.55A output while the internal protections monitor temperature and current. The design is built to safely power the target device under varying conditions without shutdown. Buyers needing higher wattage or a different voltage should select another model.

Questions about this item

How do I connect the 16V 4.55A round-tip output to my laptop and what step is often missed?

Plug the round tip firmly into the laptop's DC jack until it seats, then attach the supplied power cord to the adapter's AC inlet and a 100-240V~50-60Hz wall outlet.

Which part of this 72W adapter is most likely to need replacement after extended use?

The detachable power cord and the output cable near the round tip see the most flexing; inspect them periodically for wear or damaged insulation.

What is the first limit reached when this 16V 4.55A unit runs continuously at full load?

The 72W output rating caps sustained delivery; internal overheating protection (IO) will activate if that limit is exceeded for too long.
