Hi @angrymickey,

Welcome to the HP Support Community. 

I'd be happy to help you! 

I understand that your HP Pavilion Gaming Laptop 16-A0045nr Notebook PC does not charge and also the power LED blinks 3 times.

This issue could occur if the BIOS is not updated.

And here's the step-by-step guide for you in the link.

Let's go through a few steps to resolve this issue.

The issue with your HP Pavilion Gaming Laptop 16-A0045nr not charging and the power LED blinking three times indicates a hardware problem, often related to the battery or power supply. Here are the steps you can take to diagnose and possibly resolve the issue:

Power LED Blinking Code

Typically, the blinking LED pattern can indicate specific hardware issues. In HP laptops, three blinks usually point to a problem with the RAM or the battery.

Basic Troubleshooting Steps

Perform a Hard Reset

• Disconnect all external devices (USB drives, external monitors, etc.).
• Unplug the laptop from the power source.
• Press and hold the power button for about 15 seconds.
• Reconnect the power adapter and try turning on the laptop again.

Check the Power Adapter

• Ensure the power adapter is working correctly. If you have access to a multimeter, you can check the output voltage to ensure it's delivering the correct power.
• Try using a different power adapter if possible to rule out a faulty adapter.

Inspect the Charging Port

• Check the laptop’s charging port for any visible damage or debris. Gently clean it if necessary.

Battery and Power Reset

Remove and Reinsert the Battery

• If your laptop has a removable battery, remove it and then reinsert it. For non-removable batteries, you can skip this step.

Battery Calibration

• Sometimes, calibrating the battery can help. To do this, let the battery fully discharge until the laptop shuts down, then charge it to 100% without interruption.

I am sharing the other set of steps in the next post. Kindly check.

Hope this helps! Keep me posted for further assistance.

Hi @angrymickey,

Here are the remaining steps. 

Advanced Troubleshooting

Check RAM Modules

• Since three blinks can indicate a RAM issue, try reseating the RAM modules. If you have multiple RAM sticks, try using them one at a time to identify if one is faulty.

Run HP Diagnostics

• Turn on your laptop and immediately press the F2 key repeatedly until the HP PC Hardware Diagnostics UEFI menu appears.
• Select System Tests and then run a Quick Test or Extensive Test to identify any hardware issues.

BIOS Update

1. Update BIOS
   • Sometimes, a BIOS update can resolve hardware recognition issues. Check the HP support website for any available BIOS updates for your model.

• If the above steps do not resolve the issue, it might be a more serious hardware problem that requires attention. Contact HP phone support for further assistance. If your laptop is under warranty, they might offer repair or replacement options.

Summary

• Perform a hard reset and check the power adapter.
• Inspect and clean the charging port.
• Remove and reinsert the battery, if possible.
• Reseat or test the RAM modules.
• Run HP Diagnostics for hardware tests.
• Update the BIOS if available.

By following these steps, you should be able to determine whether the issue is something you can fix yourself or if it requires service/repair.

Hope this helps! Keep me posted for further assistance.
