The method relates to minimizing power consumption in a computing device, which executes the requested tasks in a high power mode, in which it has normal processing power and, correspondingly, normal power consumption, and which, after it has executed the requested tasks, is switched to a low power mode, in which it has limited processing power and, correspondingly, a considerably lower power consumption. In the method of the invention, the power consumption of a computing device is decreased by lengthening the time during which the device remains in the low power mode in such a way that the device is not switched to a high power mode immediately when the user starts the input, but the switching is delayed. The switching to the low power mode can be done on the basis of a sign included in the input, after a certain time (set or programmable) has passed since the input began, when a specified time has passed since the input stopped, or when a certain amount of information has been received after the input began. The means for the user input may preferably comprise a touch screen and a pen means.
