HP 90W USB-C Adapter for Spectre and EliteBook
This 90W USB Type-C power adapter is built for HP Spectre 15-bl000, 15-bl100, x360 Convertible PC, EliteBook x360 1040 G5 and EliteBook 1040 G4 models. It delivers 20V at 4.5A through a USB-C connection for compatible laptops. Business professionals and frequent travellers get a compact charger matched to these specific HP devices.
Installation and common issues
The adapter plugs directly into a USB-C port and accepts 100-240V AC input for worldwide use. No driver installation is required for basic charging operation. Connection problems usually stem from using a non-compatible laptop or a damaged USB-C port on the device. Verify the exact model number before purchase to avoid fitment errors.
Capacity and headroom
Rated at 90W output, the unit comfortably powers the listed Spectre and EliteBook laptops during normal workloads and charges the battery simultaneously. Headroom decreases when driving high-performance tasks that push the system beyond the adapter's 90W limit. It cannot supply enough current for larger workstations or models requiring higher wattage.

Questions about this item
How do I confirm the adapter is delivering 20V at 4.5A after plugging it in?
The laptop battery icon will show charging and the power LED on the Spectre or EliteBook will light; a USB-C power meter can verify 20V 4.5A output.
What comes in the box and do I need to buy a mains lead separately?
The adapter has a fixed USB-C output cable; a standard IEC C5 cloverleaf mains cable for 100-240V AC input is required and sold separately.
Which part number matches my HP Spectre 15-bl100 — 904144-850 or L45440-003?
Both numbers refer to the same 90W USB-C charger; either MPN is correct for the Spectre 15-bl100 and the other listed models.
