Q: There are so many benefits in standby and hibernation, but also shut down? Or is it better to change hibernation directly to shutdown?
A: Although the advantages of standby and hibernation are obvious, ACPI/APM is required for both hardware and system. If the hardware or system is not supported, the standby and hibernation functions are forcibly used, and it is easy to lose data. The system is unstable or even crashes; at the same time, hardware changes can only be made in the case of a real shutdown, such as replacing devices, adding memory upgrades, etc., so they cannot replace the shutdown.
Q: I accidentally lost the "standby" in "Start → Shutdown". How can I recover?
A: Generally speaking, such problems as long as the reinstall motherboard drivers will be able to solve, or the "Device Manager" in support "ACPI" hardware deleted, and then restart the machine, the system prompts Reinstall these hardware. If you cannot stand and hibernate on a newly installed system, or the system fails to start after performing these functions, first confirm in BOIS that STD and STR have been turned on. If it is already open, confirm whether the hardware supports ACPI (especially the motherboard). ), or consider the issue of hardware conflicts.
Q: I am using Windows XP. I have selected "Use password protection on recovery" in the screen saver window, but the strange thing is that it does not work. After the screen saver starts, move the keyboard or mouse to end the screen saver, and there is no window for entering the password!
A: In Windows XP, only the "resume, password protect" the choice does not work. Right-click on the desktop to open "Properties", select "Advanced" in the Power Options Properties window, and check "Prompt for password when the computer resumes from standby." In addition, the screen saver password of Windows XP is different from that of Windows 9x. The password cannot be set separately. It can only be opened by the user password when the system logs in.
Q: Sometimes my computer has been used for a long time, I want to take a break, then I chose to let the computer sleep, but the computer often does not respond at all?
A: Sleep is to save the data in memory to the hard disk, because the computer is running a long time, and save part of the data does not often run into virtual memory, sleep and then select the virtual memory section If the data is not released in time, there will be no reaction after performing dormancy. In this case, it is recommended to restart the computer.
Q: I often have to make plans or thinking about programming time, so leave the computer. But sometimes thinking time is too long, and when you use a computer, it often causes a crash. Why is this?
A: For many like graphics, programming users, pay attention to the process of debugging try to avoid going to sleep because the Windows startup screen saver, go to sleep is by detecting the input signal (such as mobile /Click the mouse to proceed. In drawing and programming, the computer work is always very busy, but at this time, there is no need to input through the outside world. If the computer sleeps at this time, the data in the CPU and the memory will be in an "isolated" state, and wake up again. When the computer itself is awake through the software, it needs to occupy the CPU and memory resources, which often leads to memory data errors, resulting in blue screen or even crash. Therefore, it is necessary to save the disk as long as possible without using the computer for a long time, so as to avoid unnecessary losses.
Q: After entering the “Power Options→Hibernate” option on the desktop, the “Enable Hibernate Support” checkbox is grayed out.
A: The current system disk free space is smaller than the memory space while saving all the contents To Sleep memory to the hard disk, the hard disk space is greater than or equal to the memory capacity. Clean up the disk and make enough space in the system disk.
Q: Why does my Windows XP automatically resumes from standby, but after two minutes and then automatically go into standby it?
A: This is usually because the network card wakeup (Wake-on-LAN) function caused. Press Win+Break to open the “System Properties” window, then go to “Hardware→Device Manager”, double-click to expand “Network Adapter”, then double-click the NIC item to open the Properties window and cancel in the “Power Management” tab. Check the box "Allow this device to take the computer out of standby."
Q: Why does my Windows XP after standby recovery, it does not recognize USB storage devices?
A: If you are in this process: plug the USB storage device into the computer → enter standby mode → remove the storage device during standby and plug in another USB port → resume from standby. You will encounter a failure to recognize the USB storage device. The solution is also very simple, just plug the storage device back into the original USB port.
In addition, when Windows XP recovers from standby and hibernation, please do not plug in the USB storage device immediately, which will cause problems in the device. Instead, wait for more than 5 seconds.
Q: Why can't my Windows 2000 recover from standby?
A: Windows 2000 BIOS is set for APM standby time support is not good. If you enable "Advanced Power Management" in Windows "Control Panel → Power Options" and the standby time set in the motherboard is shorter than the time set in the power options, then when you want to recover from Windows standby mode , will find that can not be restored successfully, because currently in the BiOS level of standby, Windows system can not interfere with it.
In addition, Windows 2000 standby function is not perfect, for example: we have encountered can not be restored after the adoption of standby, after the computer can no longer shut down properly. Therefore, it is recommended to use the standby function less in Windows 2000.
Q: Why did I choose to reboot in Windows XP, but the computer went into standby?
A: This fault generally appears after clicking the "Start → Shutdown" shutdown dialog box, you do not use the mouse to select the restart, but directly use the keyboard arrow button to select to restart, and then press back Car key. Microsoft did not give a solution or related patches, so after encountering this failure, it is recommended to use the mouse to select "Restart", then click the "OK" button to restart.
Q: Why does Windows XP SP2 return to blue screen when it resumes from standby, stop code is STOP: 0x000000D1 (0x0000000C, 0x00000002, 0x00000001, 0xF96C49ED), DRIVER_IRQL_NOT_LESS_OR_EQUAL?
A: The reason for this failure is that you have installed Sygate Personal Firewall and resumed after a long standby time. It is recommended to upgrade the latest version of Sygate Personal Firewall, if not, please uninstall the software and use other firewall tools.
Q: Why do I stop responding and crash when I want to resume from standby?
A: The reason for this failure is usually in the process of entering standby mode, you press the shutdown button, while the "Power Management" You're the Shutdown button to turn off the computer. The solution is to go to “Control Panel→Power Management→Advanced” and change “When the computer is turned off” to “Standby”.
Q: Why can't my computer use standby and hibernation?
A: This really is a universal phenomenon, it is recommended to exclude the following aspects:
(1) is recommended for Windows to apply the latest patch, Windows 2000 should upgrade to SP4, Windows XP is upgraded to SP2 because some system critical files in previous versions have problems. For example, the old version of Usbuhci.sys will cause the USB keyboard to be unusable after recovery from standby or the USB keyboard cannot wake up Windows. This causes sleep and standby to be incorrect.
(2) to upgrade the motherboard BiOS latest drivers and chipsets.
(3) If you press the USB mouse button while the computer is in the standby state, it may cause the USB mouse and USB keyboard to fail to wake up the computer. There is no good way to solve it. I can only recommend you. Wake up the computer by pressing the chassis power button.
(4) If you are using Nero Burning Rom 5.0 ~ 5.5, the operating system is Windows XP SP1, appears in standby and hibernate the phenomenon of death. It is recommended to upgrade Nero.
