USB-C to 4.0x1.7mm DC adapter for Lenovo IdeaPad

This internal power cable converts a USB Type-C female port into a 4.0 by 1.7 mm DC plug for compatible Lenovo IdeaPad models. It suits the 310, 110 and 100 series, including the 100-14IBY and 100-15IBY variants. The adapter lets you power these laptops from a USB-C source when the original barrel jack is unavailable. Builders repairing or repurposing these specific machines will find it a direct fit.

Fits inside the chassis alongside the motherboard

The short cable routes from the USB-C port to the DC-in jack without requiring external dongles. It frees up the original charger for other uses and keeps the internal layout tidy. The connector matches the 4.0 by 1.7 mm specification used by the listed IdeaPad models. It is not suited to laptops with different barrel sizes or proprietary power inputs.

Questions about this item

How much current can the 4.0x1.7mm DC plug carry continuously for my IdeaPad 310?

The adapter passes power from a USB-C source through the 4.0x1.7mm barrel plug to Lenovo IdeaPad 310, 110 and 100 series laptops.

Does the converter get hot when powering a 100-15IBY all day?

It is a passive plug converter with no active electronics, so heat depends on the USB-C charger and the laptop's own power draw.
