Windows Vista : System not coming up from Sleep Mode.

Disable Hybrid Sleep Mode in Windows Vista Windows Vista has a neat new feature for laptops called “hybrid sleep”. Actually, Windows Vista has a neat new feature for laptops called sleep too, so I’m getting ahead of myself a bit.
Windows used to have a fairly simple hardware suspend command called “standby”. However, this operation took a while to execute (both entering and exiting standby) and it was somewhat unreliable when performed repeatedly, on certain hardware or with certain applications running. Sleep is meant to alleviate these problems by just serializing the current state into memory and then shutting down all devices other than the RAM. With the OS state simmering in memory like that, entering and exiting sleep is nearly instantaneous. However, the dark side to all this is if there is a power outage while the computer is in sleep, all of the unsaved data is lost (since it just existed in memory). That’s where hybrid sleep comes in.
Hybrid sleep saves the OS state into RAM, but it also writes it all to the hard drive as well (sort of like hibernate does). This ensures that even if power is lost, the data will remain. This all sounds like a good idea, but in practice it’s just as slow as standby was.
Now, laptops have batteries and most of them are configured to enter hibernate when the battery dips below a certain level. This means that unless the battery is physically removed, power to the RAM is never unexpectedly cut. Thus, we don’t really need the hybrid sleep feature. Unfortunately, giving hybrid sleep the pink slip is a little harder than it could be.
Step one, open up the power options setting from the control panel and select the “Change plan settings” link below the selected power plan.


Once in the resulting dialog, choose “Change advanced power settings”. Now you need to scroll through the miles and miles of options to find the “Sleep” node. Expand this, and then the “Allow hybrid sleep” node below it. You should see two options, “On battery” and “Plugged in”. Set both of these to “Off”.

Once this is done, click “OK” and you should be all set! From now on, whenever your laptop would normally go into “Sleep” – usually when the lid is closed or when inactive for a certain time – it will enter full sleep mode, rather than hybrid sleep. And when you go to awaken it from its slumbers, it should be fully responsive within a second or two of reactivation – as opposed to the 10-15 seconds after hybrid sleep.

Curious - What is the moon shaped key all about


this button puts the computer into sleep mode.

FROM WIKIPEDIA-

Sleep mode can go by many different names, including Stand By (Microsoft Windows 95-Server 2003), Sleep (Mac OS 8)-(Mac OS X) / (Windows Vista,Windows Server 2008), and Suspend (Linux). When placed in this Sleep mode, aside from the RAM which is required to restore the machine's state, the computer attempts to cut power to all unneeded parts of the machine. Because of the large power savings, most laptops automatically enter this mode when the computer is running on batteries and the lid is closed.
Though Sleep and Hibernate are generally thought as two separate functions, modern Macintoshes, Windows Vista (termed Hybrid Sleep), and some specially configured Linux machines also feature a variation of Sleep mode that incorporates the strengths of Hibernate. The RAM is copied to the hard drive before sleep mode is initiated, preserving the RAM contents in the event of a power loss.
ACPI is the current standard for power management, superseding APM 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.

Stand By Shutting off on my HP Pavilion DV5000 using Windows XP


Is your laptop's Operating System Vista? Also, does the laptop completely power off or just go to sleep and nothing you do (touchpad/pressing keys) brings it out of sleep? If it still is powered on, but won't come out of stand by, or sleep mode try this: Go to Control Panel, and on the left hand side click Classic View then double click the icon for Power Options.

There will be a few options under Preferred Plans and one is selected (Filled in dot)

Under the Power Plan that is selected, click Change Plan Settings and on the next screen, click Change Advanced Power Settings.

You will have a new window that opens up with a bunch of categories with little boxes with + signs. Click the + Sign box beside sleep to open op the menu. In the options under sleep, change HYBRID sleep and HIBERNATE to NEVER. Especially the Hybrid sleep as this was a problem I found with Vista. It sounds like the computer is going into the Hybrid/Hibernation and not comping out from it unless you power off the computer and turn it back on

Also, click the + sign beside Hard Disk and make sure the option to "Turn off Hard Disks After" is also set to NEVER
