If the iPad can lock the screen once, but can't be turned on and off by pressing for a long time, there may be a small problem with the system settings.You can try to enter Settings ->General ->Auxiliary Functions, then turn off the AssistiveTouch option, and then turn it on again.If it still doesn't work, try restarting the device or restoring the factory settings (remember to back up important data first). This should solve the problem.If the problem still exists, you may need to contact Apple customer service for professional help
