What is the Differences Between Sleep (Standby) and Hibernate


What is the Differences Between Sleep (Standby) and Hibernate

Have you ever thought of what is the differences between Sleep and Hibernate options provided by Windows shutdown function? Both commands provide a easy and quick way to leave your computer in existing last state and come back to work on it at exactly the same state later without waiting too long to system to restore itself. However, fundamentally there are significant different between them that allows users to easily choose whether they should use Sleep or Hibernate.

Sleep is commonly known as Standby in Windows system or S3 in ACPI. In Sleep mode, the power supply to non-essential and non-critical component is withheld, and most system operation is shutdown and stopped. All data in physical memory (RAM module) is still kept in internal memory, and whole system is place in stand-by mode, which can be woke up and used almost immediately. In Sleep mode, the power load reduce considerably, saving a lot of energy. However, the power must not be cut off, and must be continue to supply to the computer. Once out of power, the system will have to start again just like a newly boot computer just started from power off state.
Windows Vista has enhanced sleep mode so that on notebook computer, sleeping computer will automatically hibernate when battery power level is low. It also has built-in Hybrid Sleep mode which ensure that system state is preserved when there is power lost.
Hibernate, or S4 in ACPI, meanwhile will save the data in physical memory to hard disk drive (HDD), and then power off the computer. In Hibernate mode, a file named hiberfil.sys which has the same file size as the amount of system memory will be created on the local disk. When user wants to use the computer again, the computer will boot up and load back the state at the last hibernation. The advantage of Hibernation mode is that no power is wasted for maximum saving of power. In Hibernation dormancy, no electricity is consumed by system. Beside, restore from Hibernate is generally faster than computer reboot, and is totally different from fresh start, as users can return to the exact state of last hibernation with all programs running and documents opened intact, instead of empty desktop. The disadvantage of Hibernate is that after a period of time, there may have fragmentation of file. Users will need to defragment the volume that stores the hibernation file frequently.

How to run Android on Windows Mobile Phone

Install Android on your HTC Windows Mobile phone – Guide

Welcome to the official XDANDROID AOSP thread which is dedicated to getting Android running on our beloved HTC devices.
Phhusson: has dedicated most of his time helping users and updating kernel to run Eclair and his work for other msm7k devices. However phhusson is not alone as there are also other members working on this. You can find some of them on http://www.htc-linux.org. I've listed some of the developers i know of that currently are working on and they deserve credits and thanks. We also have to note that before this work done there was quite a substantial number of people starting working on linux for our devices. Without them we may not be where we are today. So respect and credits to everyone involved in working on linux kernel for msm devices.
I am not responsible for any damages or problems your device encounters. The build is relatively safe and shouldn't cause any problems.

OS Setup (Windows): Installing using the MBR or GPT partition style

Applies To: Windows 8.1 When installing Windows on UEFI-based PCs using Windows Setup, your hard drive partition style must be set up to support either UEFI mode or legacy BIOS-compatibility mode. For example, if you receive the error message: “Windows cannot be installed to this disk. The selected disk is not of the GPT partition style”, it’s because your PC is booted in UEFI mode, but your hard drive is not configured for UEFI mode. You’ve got a few options: Reboot the PC in legacy BIOS-compatibility mode. This option lets you keep the existing partition style. For more info, see Boot to UEFI Mode or Legacy BIOS mode.
Reformat the drive for UEFI by using the GPT partition style. This option lets you use the PC’s UEFI firmware features.

You can do this yourself by reformatting the drive using the instructions below, or if you need to preserve the data, use a third-party utility to convert the drive to GPT format.
Why should I convert my drive? Many PCs now include the ability to use the…

How to Remove Windows Genuine Advantage Notifications

Windows Genuine Advantage (WGA) notifications occur when your computer hasn't passed the validation test. The validation test can be failed due to being sold a pirated (non-genuine) copy of XP, or because you have changed your XP product key to a software-generated key, or sometimes it just happens for no reason at all. The failed validation installs three types of notifications on your computer: one on the log in screen, one log in timer, and one balloon. It also stops updates from Microsoft and disables your ability to install IE7 and Windows Media Player 11. This solution can get rid of all three notifications, even though you will still not be able to update through Windows Update. You will not be able to download things from Microsoft that requires a valid license either. EditSteps
Delete Method 1 If you have only just installed Windows Genuine Advantage notifications, simply using the system restore function will remove the program. Then refuse to accept the WGA update next tim…
