Introdução

This guide will walk you through the process of replacing the Wi-Fi card in the HP ProBook 640 G1 laptop. Sometimes the Wi-Fi may stop working even though everything else on the laptop works fine. Before replacing the Wi-Fi card, try simple fixes such as checking your network connection, turning airplane mode off, restarting the router, forgetting and reconnecting to the Wi-Fi, updating or reinstalling the Wi-Fi driver, or restarting the laptop. If the Wi-Fi still does not work after these steps, the Wi-Fi card may be faulty and replacing it can help fix the issue.

This repair requires removing battery, service cover and Wi-Fi card. Always make sure the laptop is fully powered off and not in sleep mode. Disconnect the charger and any external devices before starting.
