Replacement adapter for Sony VGN-FS840 and VGN-FS875
This 75W AC adapter supplies 19.5V at 3.96A for compatible Sony Vaio laptops. It matches the original voltage and current ratings for the VGN-FS840, VGN-FS840/W, VGN-FS875 and VGN-FS875P models. The unit includes a 6.5mm by 4.4mm barrel connector and a region-specific power cord. It is sold new with a 24-month warranty.
75W output handles charging and operation
The 75W rating delivers enough power to charge the battery while the laptop runs typical workloads. It supports the full operating range of the supported Vaio models under normal use. Headroom decreases if the system draws sustained peak loads or charges a deeply depleted battery while under heavy compute demand. The adapter accepts 100-240V AC input at 50-60Hz for worldwide mains compatibility.
Standard thermals for a 75W brick
In normal use the adapter runs warm but stays within typical limits for a 75W external supply. No active cooling is present, so heat dissipates through the plastic casing. Audible noise is limited to faint coil whine under load, which is common for switch-mode designs. Power draw from the wall matches the 75W DC output plus normal conversion losses.
