4-pin AC adapter for ThinkPad 750/755

This 4-pin AC/DC adapter replaces the original power supply for IBM ThinkPad 750, 750C, 750P, 755 and 755C models. It accepts 100-240 VAC at 50/60 Hz for worldwide use. The unit carries FCC, CE and RoHS certifications. It is intended for owners of those specific legacy laptops who need a direct replacement charger.

Protection under continuous use

The adapter includes over-current, over-voltage, short-circuit and total-power protection circuits. A smart chip provides overheating protection during extended charging sessions. High-quality wiring and anti-interference isolation materials are designed to maintain stable output over long periods. These safety features operate automatically whenever the unit is powered.

Simple connection with long reach

A 10 ft power cord gives ample length to reach distant wall outlets without strain. The 4-pin connector mates directly with the laptop's original input jack for a secure fit. No drivers or configuration are required; the adapter works immediately upon connection. Buyers needing a different pin layout or voltage for other ThinkPad models cannot use this unit.

Questions about this item

Does the 10 ft power cord stay cool when the adapter runs all day at 100-240VAC?

The adapter includes over-current, over-voltage, short-circuit and overheating protection, so the cord and brick remain within safe temperatures during continuous operation.

What must I already own to use this 4-pin adapter with my ThinkPad 750 or 755?

You need a laptop that accepts a 4-pin barrel connector — specifically a ThinkPad 750, 750C, 750P, 755 or 755C — and a standard mains socket for the 100-240VAC input.

Will this charger work alongside the original 9545 power supply I kept as a spare?

Yes, it is 100 % OEM-compatible with the 9545 specification, so it can replace or supplement the original unit without any change in voltage or connector fit.
