@JacobsK5, Welcome to HP Support Community. 

Thank you for posting your query, I will be glad to help you. 
Based on everything you've shared, here's what’s likely going on and what you can try to fix it.

🧠 What's Likely Happened

Using the Samsung charger, even briefly, might have triggered one of the following issues:

• Power circuit protection or charging IC failure: Modern laptops like your HP Transcend often have overcurrent or overvoltage protection that disables charging/power to protect the board.
• EC (Embedded Controller) lockup: The EC manages power-on/off, battery charging, etc. A bad power event can cause it to freeze or shut down completely.
• Battery/power delivery firmware confusion: The wrong charger handshake might have confused or damaged the firmware.
• Motherboard fuse/charging IC damage: Less likely if it was only for a few minutes, but still possible.

🛠️ What You Can Try Right Now

1. Perform a Real EC Reset

This is different from just holding the power button. Try this:

1. Unplug everything: charger, USB, peripherals.
2. If the battery is removable (unlikely, but if yes), take it out.
3. Press and hold Power + Mute (or F12) for 30–60 seconds. (Some HP models use Power + Windows + B or Power + V for EC reset as well.)
4. Wait 1 minute, then plug in the original HP charger and see if the white light blinks once or changes color.
5. If the laptop supports a "real" embedded controller reset through a pinhole, look for a small reset hole (usually near the vents or bottom) – you might need a SIM ejector pin to press it.

2. Try BIOS Recovery Shortcut

With the charger unplugged:

1. Press and hold Windows + B, then press and hold Power for 3–5 seconds.
2. Keep holding Windows + B for another 10 seconds, then release.
3. If there's life in the BIOS, it may attempt to recover.

3. Check the Charging LED Behavior

The white blinking LED usually means:

• 1 blink every 3–5 seconds: Battery not detected.
• Continuous blinking: Battery critically low or hardware error.

Try different USB-C ports if available and check for any faint sounds or heat (indicating the board is alive but stuck).
 

I hope this helps. 

Take care and have a good day.

Hi @JacobsK5,

Thank you so much for the update! I'm really glad to hear you were able to send the laptop in under warranty, definitely the safest choice, especially with a device in mint condition. Fingers crossed the repair goes smoothly!

Wishing you a great weekend too, and I’d love to hear the update once HP gets back to you. 😊

Take care,
