Are you experiencing issues with your Lenovo Yoga laptop's Wi-Fi connection when it is plugged into an AC adaptor? This article will provide a detailed explanation of the problem and offer a solution to help you get back online.
Understanding the Problem
Many users of Lenovo Yoga laptops have reported that their Wi-Fi connection stops working as soon as they plug in the AC adaptor. While this issue can be frustrating, it is often caused by a simple software conflict.
Power Management Settings
The problem is usually caused by the power management settings of the wireless adapter. When the laptop is running on battery power, the wireless adapter is set to use more power in order to maintain a strong signal. However, when the laptop is plugged in, the power management settings may cause the wireless adapter to reduce its power usage, resulting in a weak or non-existent signal.
Finding a Solution
Fortunately, there is a simple solution to this problem. By changing the power management settings of the wireless adapter, you can prevent the Wi-Fi connection from dropping when the laptop is plugged in.
Changing Power Management Settings
To change the power management settings of the wireless adapter, follow these steps:
- Press the Windows key + X and select Device Manager from the menu.
- In the Device Manager window, expand the Network Adapters section.
- Right-click on your wireless adapter and select Properties.
- In the Properties window, click on the Power Management tab.
- Uncheck the box next to "Allow the computer to turn off this device to save power" and click OK.
// Power management settings for wireless adapter
var adapter = Get-WmiObject -Query "SELECT * FROM Win32_NetworkAdapter WHERE NetConnectionID = 'Wireless Network Connection'"
adapter.PowerManagement.PowerSavingMode = 0
The Lenovo Yoga laptop's Wi-Fi disconnecting when it is plugged in can be a frustrating problem, but it can be easily resolved by changing the power management settings of the wireless adapter. By preventing the wireless adapter from reducing its power usage, you can maintain a strong Wi-Fi signal, even when the laptop is plugged in.
