A workaround for Windows 7 standby hibernation that cannot be awakened

These two days in the notebook installed Windows 7 Use, always have a standby sleep can not wake up phenomenon, if it is just standby or hibernate again immediately open or can restore, but wait more than a few minutes will not wake up, can only force shutdown, previously used Windows XP, Only on the big machine to use Windows 7, in order to ensure that the idea is not outdated, or patience to get used to Windows 7, the night dedicated test, the first thought is AHCI-driven problem, the result as expected.

I've written two questions about AHCI drivers before, and it's all about installing on Windows XP, and in the process of installing Windows 7, almost all of the drivers are Windows 7, using the default driver, so you don't have to focus on installing Dell's official driver, After a night of testing, as long as standby or hibernate more than four or five minutes, the power key, keyboard and mouse are useless, unable to wake up, update AHCI official drive After the problem is resolved, it seems that the default driver problem is a lot, has been found on the network card default drive intermittent network, AHCI drive standby sleep and other compatibility issues, So if you have an "unprecedented" problem with Windows 7, the first one should try to see if Windows 7 is doing a bad thing (though the last standby blue screen on WinXP was due to a hard disk problem).

　Attention:

1. The method described in this article is not the only reason why Windows 7 standby hibernation does not wake up, such as:

Advanced Power Management in the BIOS setup may also affect wake-up issues

There is a hardware shutdown problem or thermal problem during standby hibernation can also cause overheating panic, which can not wake up, of course, the crash is not necessarily a blue screen form reflected

In a friend's notebook, only the use of Windows 7 of their own SATA drive is no problem, installed AHCI will also standby panic: (, but in their own notebook must be installed just OK.)

2, this article for SATA serial Drive driver update problem, for the traditional ATA hard drive is not adapted to the traditional and hard disk installation AHCI drive will cause blue screen and so on.

3, before attempting to install, please update the system patch to the latest, all using the WIN7 default installation of the driver, the first test is still standby panic, if you still crash and change.

　A special reference to the earlier AHCI article

Previously written two AHCI driver issues, mainly for Windows XP systems and how to find the right AHCI driver, in fact, the previous two articles are exactly the same as this article, only to take care of the novice computer users will be categorized, according to the issue of the focus of the separate explanation.
