The main reasons why the computer slows down after waking up from sleep include delayed network resource recovery, congestion in background programs, slow graphics card driver response and improper system settings. The solutions are: 1. Use a wired network instead or turn off the automatic mount network disk; 2. Disable unnecessary self-start programs through the task manager and check the timing tasks; 3. Update the graphics card driver and adjust the power management settings; 4. Turn off the mixed sleep and quick start function and switch to high-performance mode to optimize the system response speed.

The computer slows down after waking up from sleep, which is not uncommon on Windows 11. Usually it is not that the system is broken, but that some background services or drivers are "waking up too slowly", or that the network, hard disk and other resources have not been fully restored, which causes you to feel stuck as soon as you turn on the computer.

Below are some common reasons and practical suggestions to help you solve this problem.

Wake up slows down

The first thing many computers do when they wake up is to connect to the Internet, especially if they are connected to Wi-Fi, they may need to re-authenticate, obtain IP addresses, and even re-mount remote disks or synchronize OneDrive files. During this period, system resources are occupied, which will naturally make you feel like "a special card just woke up."

You can try:

• Plug the network cable instead of Wi-Fi to see if it improves
• Turn off the automatically mounted network disk (especially if the connection fails)
• The impact of turning off "Allow computer to turn off this device to save power" in power management on network cards

Too many background programs, starting together causes congestion

In sleep state, the program is suspended. After waking up, they all "resumed work", and some automatic update tasks also started running at this time, so the CPU and memory could not bear it at once.

It is recommended to do this:

• Press Ctrl Shift Esc to open the Task Manager, switch to the "Startup" tab, and disable unnecessary boot program
• Check whether there are scheduled tasks that are executed immediately after wake-up (such as antivirus software scanning, Windows update check)

Graphics card/driver is not keeping pace

Sometimes, the graphics card driver reacts half a beat slower after sleep recovery, especially when the independent graphics card is switched to the graphics card state. You will see that the screen lights up first, but you can't react for a long time if you click anything.

Try these operations:

• Update the graphics card driver to the latest version
• Find the display adapter in Device Manager, right-click "Properties", and uncheck "Allow computer to turn off this device to save power" in the "Power Management" tab
• If using dual graphics cards, you can use the integrated graphics to wake up in the BIOS or NVIDIA control panel

System settings are not optimized properly

Windows 11 default settings are not always the most efficient, especially when features such as mixed sleep and fast boot are enabled, which can sometimes lead to incomplete wake-up or cache mess.

Recommended adjustments:

• Go to "Control Panel>Power Options>Change Schedule Settings>Change Advanced Power Settings", and set "Mixed Sleep" in "Sleep" to "Off"
• Enable "High Performance" mode in the "Power" option (for temporary testing)
• Check whether "Quick Start" is enabled, the path is "Control Panel > Power Options > Select the function of the power button", then click "Change currently unavailable settings" and uncheck "Enable Quick Start"

Basically, these common reasons and treatment methods. Although it seems a bit too much, in most cases, you only need to move one or two settings to significantly improve. There are not many really complicated problems, and many times the system default configuration is just too conservative.
