Having your HDDs automatically turned off after being idle can help save energy and extend a PC’s battery life.
Some Windows systems might exhibit very small amounts (bursts) of disk activity separated by relatively long amounts of disk idle time. This pattern of disk activity impacts system power savings because the disk is powered up periodically. The disk then remains in the spin-up state for at least the disk idle time out, even if the amount of disk activity that caused the disk to spin up is very small.
The Hard disk burst ignore time setting in Power Options lets users ignore this burst of disk activity up to a specified time when the Turn off hard disk after setting is determining if a hard disk is idle. By default, Hard disk burst ignore time is set to 0 (do not ignore disk burst activity).

Selective Suspend Wi-Fi — что это?
Приветствую уважаемые друзья! Сегодня поговорим про одну настройку, которую можно заметить в свойствах беспроводного сетевого адаптера. Постараюсь все написать простыми словами, поехали разбираться!))
Описание
Selective Suspend Wi-Fi — функция активирует энергосберегающий режим, при котором беспроводной адаптер использует минимум энергии при бездействии.
Скажу сразу — толку от это функции как кот наплакал…
Разбираемся
- Среди дополнительных параметров беспроводного адаптера можно заметить пункт Selective Suspend, а рядом Selective Suspend Idle Timeout in seconds.
- Selective Suspend позволяет включить или отключить энергосберегающий режим Wi-Fi-модуля. Если включить — тогда если адаптер не нужен, он будет использовать минимум энергии, пока адаптер снова не понадобится.
- Selective Suspend Idle Timeout — это интервал, через который система будет проверять используется Wi-Fi адаптер или нет. Если не используется — будет переводить его в энергосберегающий режим или вовсе отключать. Значение этого параметра лучше выставить 60 или оставить по умолчанию.
- У некоторых пользователей при использовании адаптера TL-WN722N были проблемы с сетью — сама отваливалась. Решение оказалось простым — просто отключить опцию Selective Suspend.
Собственно сама функция Selective Suspend:
Включать или нет? Во-первых экономия мизерная. Даже для ноутбука. Во-вторых из-за этой экономии могут быть глюки в работе беспроводной сети. Можно включить (Enabled) и протестировать, если проблем не будет — так и оставить. Если начнутся непонятные глюки — отключить (Disabled).
Еще в Windows есть опция USB Selective Suspend, которая находится в дополнительных параметрах схемы электропитания. Это связано не с Wi-Fi, а с USB-портами, хотя Wi-Fi модуль спокойно может быть подключен и по USB. Так вот, эта опция — позволяет переводить определенные порты USB в режим ожидания, при этом остальные будут работать в обычном режиме. Есть отдельные настройки функции для работы от батареи (On battery) или когда ноутбук работает от сети (Plugged in):
