Genuine 90W adapter for Elitebook 1040 G4

This 90W AC power adapter carries part number 904144-850 and model reference ADP-90FE B. It is built to the TPN-DA08 specification for the HP Elitebook 1040 G4 and arrives in new condition. The unit delivers the rated 90 watts through a black barrel connector and is 100 percent authentic.

Suits owners replacing a lost

Buyers who need a direct replacement for the factory-supplied adapter will find the correct voltage and connector here. Anyone who requires a bundled power cord, duck-head plug or additional accessories should look elsewhere because none are included. The adapter alone powers the notebook but cannot supply other devices or alternative tip sizes.

No accessories included changes the unboxing

The package contains only the adapter brick; no AC cable, duck head or extra tips are supplied. Users must reuse an existing C5 or C7 mains lead or source one separately before the charger can be used. This keeps cost lower but adds a preparation step for anyone without a spare cord.
