Method 1: Do not use ink. Set the standby time to 9999 minutes. No? I don't think you can sleep for 9999 minutes. That's more than 150 hours. Open start → Control Panel (on the right) → appearance and personalization (click below. Click these words) → change the screen saver (personalize the blue text below. The last set of blue characters) → next let's look at it. Wait for the next check point to adjust the time. If you click 9999, you don't have to worry about it. If it is annoying to download things, directly put the screen saver. Find the blank option and select. Click Preview. Move your hands away from the keyboard. OK Method 2: right-click windows XP system, download "my computer", "management", and "Device Manager", find the "Network Adapter" you are using, right-click the network adapter you are using, and right-click "properties", and "Power Management" "Allow the computer to turn off this device to save power" Remove the check box before
