What happens to setTimeout when the computer goes to sleep?
In a modern web browser, suppose I do a setTimeout for 10 minutes (at 12:00), and 5 minutes later put the computer to sleep, what should happen when the system

Here is my code :
<!doctype html> <html> <body> <input type="button" name="clickMe" id="colourButton" value="Start Timer" onclick="setTimeout('alert(\'Surprise!\')', 120000)"/> </body> <script> </script> </html>I have taken three scenarios that might answer the question.
Scenario 1: At 00 Seconds click on 'Start Timer' button . At 25 seconds computer falls asleep. At 1min 40 seconds wake up computer. At 2mins Alert is displayed.
Scenario 2 : At 00 Seconds click on 'Start Timer' button . At 26 seconds computer falls asleep. At 3 mins, I wakeup the computer. The Alert is displayed.
Scenario 3 : This one is truly astounding.
<input type="button" name="clickMe" id="colourButton" value="Start Timer" onclick="setTimeout('alert(\'Surprise!\')', 600000)"/>At 00 Seconds I click on 'Start Timer' button. At around 1min 30 seconds the computer is on hibernate mode (my pc takes a minute to initiate hibernate)
At 8 mins I turn the laptop on. At 10 mins exactly, the alert pops up.
