Application Programming Interface (API)

Application Programming Interfaces (APIs) are sets of functions or routines
that specify how software components should interact with each other. The
APIs are, to the end user, entirely invisible and function behind the
scenes, handling such tasks as process thread management, error handling,
rendering output for graphic user interfaces (GUIs) and other core functions
that are part of the computing experience.

Not too long ago I bought a new desktop

PC. Whenever I put it to sleep, in no time flat it was awake again. A little
research revealed that this is not an uncommon problem and can have several
possible sources. Malware infections are sometimes the cause but more often
it is some device that is waking the machine up and that was the case for
me. In this tip, I will describe several settings in your system that may
keep waking up your PC. The discussion is for Windows Vista/7. You will
generally need administrator privileges to make system changes.

*Step 1) Stop the mouse from waking up the PC

Mice, especially, wireless mice, can sometimes wake the PC up. In fact,
there is a specific setting to allow this. If the mouse turns out to be a
problem, you can change the setting with this procedure:

1. Open the Start menu and type “mouse” (without quotes) in the Search
bar

2. Under the Control Panel list, click “Mouse” (or just press Enter in
Vista)

3. In the dialog box that opens, select the tab “Hardware”

4. Highlight the entry for your mouse and click the button “Properties”

5. A new dialog will open. Click the button “Change settings”

6. In the new dialog that opens, click the tab “Power Management”

7. Remove the check by “Allow this device to wake the computer”

8. Click “OK” and close the dialogs.

*Step 2)Stop a network card from waking up the PC

From what I read, a network card is the most common source of wake-up
problems and that was the cause of my own computer never staying asleep.
Here is how to configure a network card:

1. Open Device Manager. There are many ways to do this but a quick way is
to enter “dev” (without quotes) in the Start search bar and click “Device
Manager”

2. Arrow down to “network adapters” and Expand the list by pressing the
right arrow.

3. There may be several adapters, one for Ethernet, one for wireless,
and others like Bluetooth.

Keyboard users,

aArrow . down to the adapter to be configured.

b. Tab to properties and press the spacebar.

If using a mouse,

a. Right-click the adapter to be configured

b. choose “Properties”.

4. In the dialog that opens, shift-Tab to Power Management” or click this
tab sheet.

5. Remove the check by “Allow this device to wake the computer” A simple
way to do this is to press the spacebar. This toggles a checkbox on/off.

6. From the keyboard, tab to “okay” and press the spacebar. Then close
out of device manager.

Mouse users, Click “OK” and close up Device Manager

*Step 3)Scheduled tasks , updates, and other causes

Sometimes a task or Windows Update is scheduled for a specific time and will
wake up the computer. Dealing with these and other possibilities are
discussed at this link

*Step 4) Use the command line to find what causes the PC to wake up

a. One way to find out what is causing a wake-up problem is provided by the
command line. Open a command prompt and enter this command:

powercfg -lastwake

The last device that woke up the system will be shown

b. To find out which devices are enabled to wake up the PC, enter this
command

powercfg -devicequery wake_armed
