Laptop charges temporarily, then stops charging

[httpstarlost]

Hi there, my laptop has recently stopped charging when plugged in to the AC adapter. It will charge very briefly (indicated by the orange charging LED, perhaps for 30~ seconds which may go up 1%), then stop charging entirely (charging LED is white).

I've ran HP support assistant - tells me to replace it, and I've ran HP Diagnostics - tells me it is a blown fuse. However, when I run diagnostics without the AC adapter, it passes the checks. Furthermore, when I ran HP diagnostics immediately after plugging the AC adapter in, it will stay properly charging (orange light) and pass its checks. As soon as I exited diagnostics the light turned white and is on the same charge % (not charging).

Laptop is a HP Laptop PC 14-d2000 (2P5F4AV). Thank you for any help!

Hi @httpstarlost 

Welcome to the HP Support Community! We're here to help you get back up and running.

Thank you for explaining the issue so clearly. It’s genuinely frustrating when your laptop teases you with a brief charge, only to stop abruptly—especially when diagnostics offer conflicting results. 

Based on your description and similar cases, this behavior points to a hardware-level fault in the battery circuit, most likely a fuse degradation or intermittent power rail failure.

Let’s walk through a structured path to help you move forward:

What’s Likely Happening

Charges briefly, then stops (orange → white light):
This usually means the AC adapter is detected but the internal charging circuit cuts out.

Diagnostics only passes while actively running:
When the system is stressed by diagnostics, power is forced through; as soon as normal operation resumes, the protection circuit trips.

HP Diagnostics reported "blown fuse":
Modern HP boards have soldered charging fuses and MOSFETs that protect against overcurrent. If one is damaged, you get intermittent charging just like this.

 

Recommended Actions

1. Try a Known-Good HP AC Adapter

Even if your adapter appears functional, a voltage drop under load can trigger charging faults:

• Use a genuine HP adapter with matching wattage and connector
• Avoid third-party or universal chargers

If the issue persists with a known-good adapter, the fault is internal.

 

2. Run Battery Calibration

Sometimes calibration can help the system re-sync with the battery controller:

• Fully shut down the laptop
• Plug in the charger and let it sit for 30 minutes (even if not charging)
• Boot into BIOS (Esc → F10)
• Let the system idle in BIOS for 30–60 minutes
• Then boot into Windows and check battery behavior

 

3. Check for BIOS or EC Firmware Update

• Visit the HP 14-d2000 driver page
• Enter your product number: 2P5F4AV
• Download and install the latest BIOS and firmware updates

These updates may include charging logic improvements or fuse detection refinements.

 

4. Consider Battery Replacement

If diagnostics consistently report a blown fuse, and calibration or firmware updates don’t resolve it:

• The internal battery fuse may be partially degraded, causing voltage instability
• You can order a replacement battery from HP or a certified supplier
• Use HP PartSurfer to confirm the correct part: HP PartSurfer

Let me know what happens after trying a different adapter or checking for firmware updates—I’ll guide you through the next phase. 

You’re clearly being thorough and proactive, and this kind of issue deserves a clean resolution.
