The first time you open it, Windows asks if you want it to be your primary alarm; if you say Yes, then it will be able to get your attention by displaying notification bubbles on the screen when the time comes.
If you travel much, this feature could turn out to be one of your machine’s most useful functions. It’s reliable, it’s programmable, and it’s fun to use.
Microsoft starts you off with a dummy alarm, set to 7:15 a.m., but switched off.
To change the time, click the bullseye-shaped alarm to enter editing mode; now drag the two round handles around the circle to specify the alarm time (Figure 4-1). The inner, darker handle sets the hour; the lighter, outer one sets the minute.
Figure 4-1. Top: The Alarm app can’t wake the computer to wake you. You should think of it more as a system to remind you of something while you’re actually working (and the computer is on and awake). Bottom: The Timer is a countdown. You can set up multiple timers, by the way; tap to set up another one. To delete one, tap it and then tap .
Occurrence. Tap Repeats to specify what days this alarm rings. You can specify, for example, Mondays, Wednesdays, and Fridays by turning on those three checkboxes. (Tap one again to turn off its checkmark.)
When you finally hit the button, the Alarm screen lists your new alarm. Just tap the On/Off button below the display to prevent an alarm from going off. It stays in the list, though, so you can quickly reactivate it another day, without having to redo the whole thing.
When the alarm goes off, a notification appears on the screen, identifying the alarm and the time, and the sound rings. (If your machine is already on and awake.)
You can snooze it or dismiss it (turn it off for good).
The second tab in the Alarms app, Timer, is a countdown timer. You input a starting time, and it counts down to zero (Figure 4-1, bottom).
Countdown timers are everywhere in life. They measure the periods in sports and games, cooking times in the kitchen, penalties on “The Amazing Race.”
Drag the handles of the two dials to specify the number of minutes and seconds you want to count down. The inner ring sets the minutes (and hours, if you drag it around the whole circle); the outer ring sets the seconds.
Not much happens when the timer runs out; it just kind of stops. There’s no notification, no sound—so it’s probably best if you don’t trust it to remind you when it’s time to take the roast out of the oven.
While the digits are flying by, you can tap the Lap button () as often as you like. Each time, the list at the right identifies how much time elapsed since the last time you tapped Lap. It’s a way for you to compare, for example, how much time a runner is spending on each lap around a track. The Splits column tells you how much time has elapsed since you started the stopwatch.
