The computer appears the blue screen code 0x000000a5 How to solve ?

Failure One:

1. Error Analysis:

This is typically because the motherboard BIOS does not fully support the ACPI specification. For example, there is a computer for Lenovo brand machine, the user has replaced the motherboard, but did not reload a key recovery software, resulting in the boot blue screen. Because a key recovery program requires ACPI support, replacing a motherboard part may cause an unsupported error to occur if the BIOS program does not recognize the associated file of the original one-key recovery.

2. Solution:

You can refresh the BIOS, and if you do not have the appropriate BIOS upgrade, when you install Windows 2K/XP, when the press F6 if you need to install a third-party SCSI or RAID driver prompts, click The F7 key so that the Windows operating system automatically disables the installation of the ACPI HAL and installs the standard PC HAL.

When the computer resumes from hibernation, the "Stop 0x000000a5" the ACPI BIOS in the system is not fully compliant with the ACPI specification "(Stop 0x0000 00A5, the ACPI BIOS in the system does not fully comply with the ACPI specification) error message.

2, the problem reason:

This problem may occur if you add random access memory (RAM) to the computer when it is in hibernation. When the computer resumes from hibernation and loads the Hiberfil.sys file, Microsoft Windows detects changes in the memory state and you receive the error message.

3. Solution:

Restart your computer, and if the problem persists, you can start the computer by using the Windows installation CD or by using the Emergency Boot disk (you need to set the CD-ROM as the first boot entry in the BIOS), and then delete the Hiberfil.sys file.

When the "Welcome to Setup" screen appears, press the R key to start the Recovery Console. If your computer is configured for dual-boot or multiple-boot, select the appropriate Windows XP installation. When prompted, type the administrator password, and then press ENTER. By default, Hiberfil.sys is typically located in the root directory (C:). At the command prompt, type del hiberfil.sys, and then press ENTER. Restart your computer.

Reason analysis: You need to press F7 to turn off the ACPI features of Windows XP during Setup. Windows XP ACPI does not support some special features in the BIOS because of the older Windows XP system.

Solution:

② during the installation of Windows XP, press F6 if you need to install will appear. When prompted, press a few F7 keys, you can normally install.

Note:

Because the ACPI Advanced Power management feature is turned off, the Windows XP operating system may affect other power management operations, such as sleep, hibernation, and so on, when the computer shuts down, it also prompts "you can safely shut down", at which point you need to press the power switch again to properly shut down. This is a normal behavior caused by turning off ACPI functionality. For a better operational experience, this notebook recommends installing Windows 7 or Windows 8 operating systems.
