X220 Tablet in UltraBase 3 won't run with lid closed

I sometimes dock my ThinkPad X220 Tablet in an UltraBase Series 3 connected to AC power, external display, keyboard, and mouse. In this setup I would prefer to keep the tablet screen closed while the machine is running.

But the computer always puts itself to sleep when I close it, even though I have set the power options to 'Do nothing' when I close the lid.

I am running Windows 7 Home Premium.

Can anyone here help me to fix this please?

For the record, I have solved the problem by changing Windows settings as follows:

 

Control Panel -> Hardware and Sound -> Power Options -> Change Plan Settings -> Change Advanced Power Settings.
Under Procecessor Power Management, set both Minimum and Maximum settings to 100%.
