Questions about this item

How do I connect the 6.5mm x 4.4mm barrel plug to my Sony PCG-GRX707 and which step do people often miss?

Plug the barrel connector firmly into the laptop's DC jack until it seats fully, then attach the supplied power cord to the adapter brick and into a 100-240V 50-60Hz wall outlet; the step most often missed is pushing the barrel in until it clicks rather than leaving it partially inserted.

What part of this 75W adapter will need replacement first and after roughly how long?

The detachable mains cord and the DC cable near the barrel plug are the wear items; with daily flexing they typically need replacing after two to three years while the brick itself often lasts longer.

What thermal or electrical limit appears first when this 19.5V 3.96A unit runs continuously at full load?

The adapter's 75W maximum output rating is the first ceiling; sustained loads at 19.5V and 3.96A will hit that limit before any voltage-regulation or over-temperature protection engages.
