The operating system will power down most of the connected hardware devices except for the computer memory which is being used to restore the previous state once the computer ends sleep mode. The unresponsiveness of computer systems that are in sleep mode made it impracticable for certain situations where response is required. This includes staying connected to a computer network, being available in Instant Messengers and VOIP software or availability for remote access.

Sleep Talking, a new system that is called internally Somniloquy has been designed by computer scientists at UC San Diego and Microsoft Research, combines the energy saving benefits of sleep mode with the responsiveness of awake mode. An USB prototype has been created that acts as a low end computer system impersonating the host computer on the network. The prototype comes with the ability to wake the host computer system if necessary. This can be an incoming call using voice over IP or a P2P download that filled the internal flash memory of the USB prototype so that the contents have to be written to the host computer system.

Tests that the researchers conducted resulted in power savings between 60 and 80 percent depending on the use model compared to idle state which is

Now you probably want to rest a little bit and enjoy the days off as much as possible. You might appreciate some kind of stimulant that would help you loosen the tension and concentration accumulated in your mind and body..

NapSounds.com is a very simple website aimed at providing a good content rather than an amazing design. What you can get here for free are daily updated power-nap sounds that are able to help you enjoy a few-minute rest every day to “recharge your batteries” in a short time. Power-nap is actually a really short rest during your day which – if performed the right way – can equal up to several hours of sleep. Power-nap sound containing varied sound effects and melodies picked for this purpose is the thing that should help you enjoy your short rest the right way.

These power-naps also contain special binaural beats, sounds split into 2 stereo channels and then merged by human brain again, though you need stereo headphones to make use of them. Besides daily updated preset naps you’re also allowed to compose your own nap according to your priorities. Just note that due to the nature of these sound tracks, you should only listen to them when you’re not doing any activity (like driving a car) and avoid listening to it if you suffer from epilepsy or are pregnant.

I use to work a lot and often stare at a computer screen for 10+ hours a day. When I´am finished I shutdown the pc and go to sleep. Most of the time I have problems sleeping right away and start to think about what I did today and what I have to do tomorrow.

An article from psychology today tries to shed some light into sleeplessness. Its a great read with some useful information. Have a nice Sunday.
