Product: HP Spectre x360 16 inch 2-in-1 Laptop PC 16-aa0000 (7M3L2AV)
Operating System: Microsoft Windows 11

Hi,

I’m using a HP Spectre x360 2-in-1 Laptop 16-aa0xxx (32 GB RAM, BIOS F.13 from March 20, 2025, Windows 11 24H2), and I'm having trouble charging the device with a USB-C power bank.

The power bank is the Anker 737 (PowerCore 24K) with USB-C1 PD 3.1 / 140W output.
I'm using a fully EPR-certified 240W USB-C cable (Silkland, 20Gbps, 5A/48V), and I've tried multiple charging scenarios:

✅ Laptop on
✅ Laptop fully powered off
✅ Different USB-C ports
✅ Power bank fully charged

The issue:

  • The power bank display keeps blinking as if the connection is being repeatedly made and dropped.

  • It shows only 0.1W power output on USB-C1.

  • The laptop does not charge at all – not even when turned off.

What I suspect:

  • The USB Power Delivery 3.1 handshake seems to fail.

  • The laptop may be blocking non-HP chargers or rejecting unknown PD 3.1 vendor IDs.

Questions:

  1. Does my model support third-party USB-C PD 3.1 charging at 140W?

  2. Is there a BIOS setting or firmware restriction that blocks non-HP power sources?

  3. Is an official HP 140W USB-C adapter mandatory for this device?

I would really appreciate any insight. I’d love to use this laptop with a power bank on the go, but right now it seems impossible.

Hi @codewatcher_834 

 

According to the Anker specs page, you need the PD to be version 3.1 to get 140 watts and you have a PD 3.0 see page 2 manual service

 

Maintenance and Service Guide HP Spectre x360 16 inch 2-in-1 Laptop PC Model numbers: 16-aa0xxx

 

 

Anker 737 Power Bank (PowerCore 24K) - Anker US

 

To reach 140W, you need to use a cable that supports PD 3.1 and a device that supports PD 3.1 input such as the 2021 MacBook Pro 16.
