How to set the laptop, the monitor can still continue to run
In the advanced options in the power options properties, you can set up, close the lid and take no action.
Control panel - power management - close the lid and choose not to take any action.
In the power options, set the lid action for nothing to do ~!
Right click on the desktop, property - screen saver - power - Advanced - and on the portable computer, the standby instead of taking any action is fine, I hope to adopt.
