[Alper11]

I’m experiencing an issue with my laptop where the Wi-Fi connection drops a few minutes after unplugging the power supply, and even if I reconnect, it disconnects again after a few minutes.

Hi @Alper11,

Welcome to the HP Support Community. 

I'd be glad to help you! 

The issue you're experiencing with your HP 15.6-inch Laptop PC 15-fc0000 (733M2AV) seems to be related to power management settings affecting the Wi-Fi adapter when the laptop is running on battery. Here are some steps to help resolve the problem:

1. Adjust Power Management Settings for Wi-Fi Adapter:

• Right-click on the Start menu and select Device Manager.
• Expand Network adapters and find your Wi-Fi adapter (e.g., Realtek, Intel).
• Right-click on the Wi-Fi adapter and select Properties.
• Go to the Power Management tab.
• Uncheck the option “Allow the computer to turn off this device to save power.”
• Click OK to save the changes.

2. Change Power Plan Settings:

• Go to Settings > System > Power & sleep > Additional power settings.
• Click on Change plan settings next to your active power plan.
• Click on Change advanced power settings.
• Expand Wireless Adapter Settings > Power Saving Mode.
• Set both "On battery" and "Plugged in" to Maximum Performance.
• Click Apply and OK.

3. Update or Reinstall the Wi-Fi Driver:

• Go to Device Manager and find your Wi-Fi adapter.
• Right-click and select Update driver.
• Choose Search automatically for drivers to let Windows find and install the latest drivers.
• If this doesn’t work, you can try uninstalling the driver and then restarting your laptop. Windows will automatically reinstall the correct driver.

4. Disable USB Selective Suspend:

• Open Control Panel > Power Options.
• Click on Change plan settings for the active plan.
• Go to Change advanced power settings.
• Find USB settings > USB selective suspend setting and set it to Disabled.
• Click Apply and OK.

5. Check for BIOS/UEFI Updates:

• Visit the HP Support website and enter your laptop's model number.
• Check if there is an available BIOS/UEFI update for your laptop. If so, download and install it, as it might contain fixes for power management and connectivity issues.

6. Perform a Network Reset:

• Go to Settings > Network & Internet > Status.
• Scroll down and select Network reset.
• Follow the prompts to reset your network settings, and restart your laptop.

After completing these steps, monitor if the Wi-Fi connection remains stable when unplugged from the power supply. If the issue persists, there could be a hardware problem with the Wi-Fi adapter or a deeper software conflict.
