Sleep mode (or suspend to RAM) is a low power mode for electronic devices such as computers, televisions, and remote controlled devices.These modes save significantly on electrical consumption compared to leaving a device fully on and, upon resume, allow the user to avoid having to reissue instructions or to wait for a machine to reboot.Many devices signify this power mode with a pulsed. May 27, 2020 This free software for Mac OS X is a product of By Limit Point Software. From the developer: NoSleep is an application that you use to prevent your computer from going to sleep and for waking it at a specified time and then keeping it awake. To extend the life of your battery, set your Mac to automatically switch between graphics modes. 'Computer sleep' and 'Display sleep' sliders, or 'Turn display off after' slider. Drag the slider to set the amount of time your computer or display should wait before going to sleep. Put hard disks to sleep when possible.
Your Mac computer is set to go to sleep after a certain amount of time in order to help conserve power or your laptop's batteries. However, it can be annoying if your computer is going to sleep when you don't want it to. Here's how to turn off sleep mode on a Mac using System Preferences and keep it awake with third-party apps.
If your Mac of choice is a portable one, it most definitely also has a lid which, when closed, will automatically send your computer to sleep. Although this is, in most cases, a useful feature, at times it will also mean that apps you need to run around the clock will be forcefully stopped. On your Mac, choose Apple menu System Preferences, then click Energy Saver. Open Energy Saver preferences for me. Do any of the following: Set the amount of time your computer or display should wait before going to sleep: Drag the 'Computer sleep' and 'Display sleep' sliders, or the 'Turn display off after' slider. Keep your Mac from going to sleep automatically: Select.

Sleep mode (or suspend to RAM) is a low power mode for electronic devices such as computers, televisions, and remote controlled devices. These modes save significantly on electrical consumption compared to leaving a device fully on and, upon resume, allow the user to avoid having to reissue instructions or to wait for a machine to reboot. Many devices signify this power mode with a pulsed or red colored LED power light.
Computers[edit]
In computers, entering a sleep state is roughly equivalent to 'pausing' the state of the machine. When restored, the operation continues from the same point, having the same applications and files open.
Sleep[edit]
Sleep mode has gone by various names, including Stand By, Suspend and Suspend to RAM. Machine state is held in RAM and, when placed in sleep mode, the computer cuts power to unneeded subsystems and places the RAM into a minimum power state, just sufficient to retain its data. Because of the large power saving, most laptops automatically enter this mode when the computer is running on batteries and the lid is closed. If undesired, the behavior can be altered in the operating system settings.
A computer must consume some energy while sleeping in order to power the RAM and to be able to respond to a wake-up event. A sleeping PC is a case of a machine on standby power, and this is covered by regulations in many countries, for example in the United States limiting such power under the One Watt Initiative, from 2010. In addition to a wake-up press of the power button, PCs can also respond to other wake cues, such as from keyboard, mouse, incoming telephone call on a modem, or local area network signal.
Hibernation[edit]
Hibernation, also called Suspend to Disk on Linux, saves all computer operational data on the fixed disk before turning the computer off completely. On switching the computer back on, the computer is restored to its state prior to hibernation, with all programs and files open, and unsaved data intact. In contrast with standby mode, hibernation mode saves the computer's state on the hard disk, which requires no power to maintain, whereas standby mode saves the computer's state in RAM, which requires a small amount of power to maintain.
Hybrid sleep[edit]
Sleep mode and hibernation can be combined: the contents of RAM are first copied to non-volatile storage like for regular hibernation, but then, instead of powering down, the computer enters sleep mode. This approach combines the benefits of sleep mode and hibernation: The machine can resume instantaneously, but it can also be powered down completely (e.g. due to loss of power) without loss of data, because it is already effectively in a state of hibernation. This mode is called 'hybrid sleep' in Microsoft Windows other than Windows XP.
A hybrid mode is supported by some portable Apple Macintosh computers,[1] compatible hardware running Windows Vista or newer, and Linux distributions running kernel 3.6 or newer.

ACPI[edit]
ACPI (Advanced Configuration and Power Interface) is the current standard for power management, superseding APM (Advanced Power Management) and providing the backbone for sleep and hibernation on modern computers. Sleep mode corresponds to ACPI mode S3. When a non-ACPI device is plugged in, Windows will sometimes disable stand-by functionality for the whole operating system. Without ACPI functionality, as seen on older hardware, sleep mode is usually restricted to turning off the monitor and spinning down the hard drive.

Microsoft Windows[edit]
Disable Sleep For Mac
Microsoft Windows 2000 and later support sleep at the operating system level (OS-controlled ACPI S4 sleep state) without special drivers from the hardware manufacturer. Windows Vista's Fast Sleep and Resume feature saves the contents of volatile memory to hard disk before entering sleep mode (aka Hybrid sleep). If power to memory is lost, it will use the hard disk to wake up. The user has the option of hibernating directly if they wish.
In older versions prior to Windows Vista, sleep mode was under-used in business environments as it was difficult to enable organization-wide without resorting to third-party PC power management software.[2] As a result, these earlier versions of Windows were criticized for wasting energy.[3]
There remains a market in third-party PC power management software for newer versions of Windows, offering features beyond those built into the operating system.[4][5][6] Most products offer Active Directory integration and per-user/per-machine settings with the more advanced offering multiple power plans, scheduled power plans, anti-insomnia features and enterprise power usage reporting. Vendors include 1E NightWatchman,[7][8] Data Synergy PowerMAN (Software)[9] and Verdiem SURVEYOR.[10]
macOS[edit]
Sleep on Macs running macOS consists of the traditional sleep, Safe Sleep, and Power Nap. In System Preferences, Safe Sleep[11] is referred to as sleep. Since Safe Sleep also allowed state to be restored in an event of a power outage, unlike other operating systems, hibernate was never offered as an option.
In 2005, some Macs running Mac OS X v10.4 began to support Safe Sleep. The feature saves the contents of volatile memory to the system hard disk each time the Mac enters Sleep mode. The Mac can instantaneously wake from sleep mode if power to the RAM has not been lost. However, if the power supply was interrupted, such as when removing batteries without an AC power connection, the Mac would wake from Safe Sleep instead, restoring memory contents from the hard drive.[12]
Safe Sleep capability is found in Mac models starting with the October 2005 revision of the PowerBook G4 (Double-Layer SD[vague]). Mac OS X v10.4 or higher is also required.[13]
In 2012, Apple introduced Power Nap with OS X Mountain Lion (10.8) and select Mac models.[14] Power Nap allows the Mac to perform tasks silently, such as iCloud syncing and Spotlight indexing. Only low energy tasks are performed when on battery power, while higher energy tasks are performed with AC power.[15]

Unicode[edit]
Because of widespread use of this symbol, a campaign was launched to add a set of power characters to Unicode.[16] In February 2015, the proposal was accepted by Unicode and the characters were included in Unicode 9.0.[17] The characters are in the 'Miscellaneous Technical' block, with code points 23FB-FE.[18]
Thus, it can be used to create ringtones for you phone or pad, etc.It's worth noting that Joyoshare Media Cutter for Mac supports lots of audio file formats including MP3, WAV, WMA, AAC, AC3, OGG, AIFF, RA, M4A, M4B, M4P, M4R, MP2, MPA, MKA, RAM, APE, FLAC, AA, etc, so that you can use any media file in different formats to become a ringtone. Besides iPhone, iPad and Android generic, you can also create ringtones for Windows Phones, Blackberry, Motorola, LG Optimus, etc.Pros. Besides, you can also adjust the volume and weighting of the audio file, add special sound effects to the audio, extract audio from video, etc. Ringtone makers for mac.
The symbol is ⏾ (⏾)—defined as 'Power Sleep Symbol'.[18]
