These two days in the notebook installed Windows 7, always appear after the standby hibernation can not wake up, if it is just standby or hibernate and then open immediately can be restored, but wait for more than a few Minute can not wake up, can only force shutdown, has been using Windows XP before, only use Windows 7 on the big machine, in order to ensure that the idea is not outdated, or endure the habit of Windows 7, special test at night, the first thought is The AHCI-driven problem was as expected.
Tianyuan wrote two questions about AHCI drivers before they were installed on Windows XP. In the process of installing Windows 7, almost all drivers are Windows 7 and use the default driver. So I didn't have the official driver to install DELL. After night test, as long as standby or hibernation is more than four or five minutes, Power button, keyboard and mouse are useless, can't wake up, update AHCI official driver problem, it seems that the default driver There are still many problems. At present, there are compatibility problems such as NIC default driver intermittent network disconnection, AHCI driver standby hibernation, etc., so if you encounter the problem of “unprecedented” on Windows 7, the first one should try whether It was caused by Windows 7 good things (but the last time the standby blue screen on winXP was completely due to the problem of the hard disk).

2, this article for SATA serial hard drive driver update problem, for traditional ATA hard drive is not suitable, for the traditional Installing the AHCI driver on the parallel port hard disk will cause problems such as blue screen.
3. Before attempting to install, please update the system patch to the latest one. All the drivers installed by default using WIN7, first test whether it is still waiting for the crash, if it still crashes and then change.
One, especially refer to the two AHCI driver problem articles written before the AHCI article
