And also, is it really better to put your computer to sleep than shutting it down?
What's the difference?

Answer 1

There are a limited nuber of devices capable of waking a system. One very common component is the LAN adapter (or network adapter, NIC, network interface, etc...). This is because your computer is capable of functioning as a rudimentary server (all Windows boxes are!). If you have your computer connected via router/switch to your home network, there are a plethora of reasons why your computer might come out of sleep.

Some, more advanced, routers will poll the network frequently to detect new computers, or changes in existing network attached hardware. This feature can be disabled on your router (usually accessed by typing "192.168.1.xxx" in an internet browser (xxx is the router number, usually 1 or 100 or 101). You'll have to consult your router manufactuerer about that. Don't worry, there's an easier fix.

Conversely, another computer on your network might be attempting to make contact with your new computer to discover shared files, or printers, or any number of other things!

EASY FIX: If this turns out to be the case, simply go into your BIOS and disable "Wake on LAN" or a similar titled feature. Please use your discretion when modifying your BIOS settings as a small change can have very big results. If you don't feel comfortable doing this, the read up on the issue a bit more.

As far as a sleep mode preference, its really up to you. I will list the various options of sleep/hibernate and let you decide what is best for your pc.

S0: Working. This is the normal state of the computer when switched on.
S1: Suspend / Sleeping 1: The CPU suspends activity but retains all its contexts in a very low-power state.
S2: Suspend / Sleeping 2: The CPU is powered down and loses its contexts, but the memory retains all of its data.
S3: Suspend / Sleeping 3: Same as S2 but devices will need to be re-initialized at the next wake-up.
S4: Hibernation / suspend-to-disk: All contexts are written to disk in a hibernation file and the system is powered off (same as S5).
S5: Soft-off: Everything has been shut down.

Hope this has been helpful.
Take care!

Answer 2

When a computer "goes to sleep" or standby, it merely goes on low power and is not off. You don't have to "tell it to sleep" -- you can have it go on standby after a certain number of minutes you set in the Control Panel.

To shutdown closes all programs and turns the PC and/or monitor off if you set it that way in the Control Panel.

Click Start, Settings, Control Panel, Power Options. Carefully study the settings and choose.

Standby: If you take a quick look around your home, you will likely see many devices that have a standby power option. Televisions, cordless telephones, CD players and, of course, the personal computer are all able to have standby power. Although the device may not be in use, if it is on standby power, it will still be consuming power.

When a device is on standby power, it is ready to be switched on instantly. Although not obviously in use, the device will still be drawing power from the electricity source, usually much more than is commonly thought to be the case. Most devices that can be switched on with a remote control have a standby power option. If you have pressed the off button on the remote but not switched the device off completely then there will still be power in the device.

I leave my computers runnign 24/7 and they seem to last forever, and my father shuts his off every night, he has gone through 3 computers and i still have my tower that I got when windows 98 came out that works just fine. so from personal experience id say leave it running. Anyway, id bet your problem is a virus or a spyware that is running in your back ground that is accessing the internet, or some other program your computer considers high priority, and so it turns back on like it is suppose to. If you want to change that setting start a new question, and ill explain, its a log explanation

Answer 4

It probably isn't sleepy yet.

Actually, the difference in shutting down & putting it to sleep are:

Shutdown - Whole computer is off.
Sleep - Computer is on, in a reduced energy state.

Sleep takes less time to access than restarting cold (supposedly).

Many computers have problems with hibernation (deep sleep) as opposed to standby. Usually, it is something to do with hardware/driver conflicts or problems.

Check for updated motherboard, video, modem, audio, usb, & ethernet drivers. Test different things. Sometimes Direct-X 9 works better than DX-8.1, sometimes it is vice versa.

Try with or without SP2 installed. Change your power settings under the control panel applet to see if you can adjust it how you want.

Use hibernate & standby to see which works best (hold down shift after you click shutdown for hibernate option to appear).

Hope these tips help.

Answer 5

if you move the mouse or hit the spacebar it will get out of sleepmode
the difference between putting it to sleep and shutting it down is that it is hard on the boot process when you shut it down and turn it back on couple times a day, sleep mode is when it sort of shuts down but not all the way, lets the computer be at rest the computer will stay on during sleep mode

hope this helps

Answer 6

it all depends on what you have running on your computer. If you have allot of background programs running then one of them could start the computer back up from stand by or sleep which ever your keyboard calls it lol.

As far as turning off your computer, as long as you go to start-shut down it will not hurt your computer at all. Its when you just press the power button or what now to turn it off that i could hurt your computer. I personally have a very powerfull computer for gameing and video and if i leave my computer on all night my electric bill is the price of a nice car lol.

Answer 7

Someone is bound to answer your question with "Gremlins", but actually, you are likely connected to the internet and you likley have things such as live updates working in the background. There are also those mischievous hackers that try to get in. If you allow other "servers" access to your computer through programs such as Bear Share, your computer is easily accessed and will activate itself from a sleep mode.

Answer 8

Because it's sick and tired of you trying to run it's life and telling it what to do. You never want it to have any fun. It's not tired and it might go to bed but it's not shutting it's eyes. It really hates you and it's not putting up with this crap anymore. Oh, dang, that was my teenager, not your computer. Sorry about that but I'm really confused right now and need to ask a question about what to do about this kid. Good luck on your 'puter problem

Answer 9

There are a number of power settings that involve sleep. Sleep mode generally shuts down the monitor until the mouse or a key is touched again.

Click start/run/type in powercfg.cpl /click ok/

You'll need to make decisions in the power settings, advanced and hibernate tabs.

Make it a great day!

Answer 10

Maybe it isn't tired yet :-)

I turn ours off for the nite, it saves energy and have never used sleep. I'm not sure what it is actually doing, maybe cycling through the programs that are automated like norton antivirus or internet hits to get online or something like that. Your best bet is to just shut it off.
