So far, so good. The open, good condition is like new, with everything in great condition. Should I worry about anything? I really like the portability and the build quality.

Hello! I am looking for a USB4 dock for PX13 GoPro Edition (considering CalDigit Element 5 Hub). Since most of the USB4 docks are supplying power to the host, I am a bit worried about using the laptop with the dock and official 200 W power adapter attached at the same time. Many of the workloads I run stress the CPU up to 100%, so I do need the official power brick and wouldn't want to rely on ~90 W delivered from the dock. However, I remember some of the earlier ASUS laptops (G14 2020?) could be damaged if one tried to use them with a PD dock and the official power adapter simultaneously attached.

I wonder if anyone had any experience of using Element 5 Hub (or other similar PD dock) with PX13 and could possibly confirm that the dock wouldn't fry the laptop if the official power adapter is also attached?

Got this open box from Best Buy and still within my return window. By all appearances it was in brand new condition. I am pretty sure I heard sound from this laptop at some point early on but not positive. I have mostly been docked to a screen with speakers or on Bluetooth headphones. Yesterday I tried to watch a video with it on my lap and nothing. I have tried all the usual windows output settings, updated sound related drivers, toggled the Asus audio enhancements, restarted, and still quiet.

Bluetooth, the 3.5mm jack, and audio through an external monitor via displayport work as expected. Am I missing something? Should I open it? The only support Best Buy offers is a drop off which is inconvient at best and I suspect not useful at worse. That is just an impression based of no first hand experience.

Any leads on where to look would be greatly appreciated.

**TL;DR:** My ASUS ProArt PX13 (HN7306WV, Ryzen AI 9 HX 370 + RTX 4060) almost always negotiates a low USB-C PD profile (~30-45W) from a 200W charger, and Windows shows a "slow charger" warning. Only very rarely — maybe 1 in 10-15 plug cycles, or when the laptop is shut down — does it briefly negotiate ~60W. Battery drains while plugged in under any load. I've exhausted every troubleshooting step I can think of.

## Hardware

- **Laptop:** ASUS ProArt PX13 HN7306WV (Ryzen AI 9 HX 370, 32GB RAM, RTX 4060 Laptop GPU, AMD Radeon 890M iGPU)

- **BIOS:** HN7306WV.316 (March 2025)

- **OS:** Windows 11 (Build 26100)

- **Battery health:** 63,293 / 73,000 mWh (~86.7%, normal wear)

- **Charger:** Anker Prime 200W 6-port GaN (A2683) — single USB-C port rated up to 100W (5V/9V/15V/20V × up to 5A)

- **Cables tested:** 3 different USB-C-to-C cables, including a brand new 240W Anker EPR cable. Original ASUS 200W proprietary adapter is at another location, not available right now.

## The Problem

This is the part that's driving me crazy: **the behavior is inconsistent and unpredictable.**

- Most of the time, charging is stuck at **30-45W** and Windows shows a **"slow charger connected"** warning.

- I have unplugged and replugged the cable **10-15 times in a row** — only occasionally does it briefly jump to ~60W, then drop back.

- When the **laptop is shut down** and I plug it in, it sometimes negotiates **~60W** (presumably because PD renegotiates from scratch with no OS running). But as soon as I boot Windows, it drops back to 30-45W and the slow charger warning appears.

- Under any actual load, the **battery percentage drops while plugged in** — the laptop consumes more than USB-C delivers.

Measured via PowerShell:

```

Get-WmiObject -Namespace root\wmi -Class BatteryStatus | Select ChargeRate, Voltage

```

ChargeRate consistently in the 16,000-43,000 mW range, rarely up to ~60,000 mW.

## What I've Tested

**Cables:**

- Stock Anker 200W cable → 17W (worst, probably faulty E-Marker)

- Generic USB-C-to-C cable → 30W

- Belkin 60W cable → consistent 60W (hit cable limit)

- Brand new Anker 240W EPR cable → still 30-43W most of the time

**Ports:**

- Both USB-C ports on the laptop — same result

- Multiple USB-C ports on the Anker Prime — same result

- Nothing else plugged into the charger (full 200W budget available)

**Software / Settings (tried every combination):**

- Windows power plan: Balanced, Performance, Power Saver, ASUS Standard, ASUS Whisper, ASUS Performance — **no difference**

- MyASUS → Battery Care Mode: **OFF**

- MyASUS → Operating Mode: tested Whisper / Standard / Performance — **no difference**

- MyASUS → GPU Mode: Standard / Eco / Optimized — **no difference**

- Disabled NVIDIA RTX 4060 in Device Manager — **no difference**

- CPU sits at 4% idle when tested, so it's not load-related

- Battery at 13-19% (well below any throttling threshold)

- Laptop cool, fans normal (not thermal throttling)

**Plug-cycle test:**

- Unplugged and replugged USB-C cable 10-15 times consecutively

- Result: mostly 30-45W with "slow charger" warning, very rarely ~60W for a moment, then back down

**Shutdown vs. on:**

- When the laptop is **off** and plugged in → sometimes negotiates ~60W

- When the laptop is **on** → almost always 30-45W with slow charger warning

This strongly suggests something in the Windows / ASUS driver / EC firmware is renegotiating the PD profile *downward* after boot.

## What I Suspect

1. **ASUS firmware is artificially capping USB-C PD input on this model.** PX13 ships with a 200W proprietary barrel adapter; ASUS may have locked USB-C charging to a low profile as an "emergency travel" mode. MyASUS literally warns: *"For best performance, please use the adapter that came with your computer."*

2. **EC/PD controller is renegotiating to a lower profile after Windows boots.** The fact that it sometimes works at 60W when shut down but always drops on boot points to a Windows-side or ASUS service intervention.

3. **Possible hardware fault in the PD chip on my unit.** But behavior is consistent across both USB-C ports, which makes me think it's firmware, not hardware.

## Questions for the Community

1. **Other PX13 (HN7306WV) owners** — what charging wattage do you see via USB-C from a 100W charger? Do you also get the "slow charger" warning?

2. **Is there a hidden BIOS setting** to disable USB-C PD wattage limiting? I've gone through every BIOS page and don't see anything obvious.

3. **Has anyone tried the EC reset** (Vol-Down + Power held 40 seconds) on a PX13 and seen USB-C wattage improve afterward?

4. **Is there an ASUS service or driver** that intentionally renegotiates the PD profile downward on boot? If so, can it be disabled?

5. **Is this actually expected behavior** — i.e., the PX13's USB-C ports are firmware-limited to ~45W on AC, with the full 200W only via the proprietary adapter? If yes, I'll stop chasing it and just use USB-C for travel only.

Any insight from PX13 owners, ASUS techs, or anyone who's solved this would be hugely appreciated. I want to rule out user-fixable issues before sending it to service.

Thanks in advance.
