Computers are one of the most frequently used electronic devices at the present stage, and they are often used in learning, training, work, as well as entertainment and leisure. If the computer is not used for a period of time, it will automatically enter sleep mode. In this case, only when we wake up the computer can it return to the menu page. However, some people may find that they cannot wake up the computer after it enters sleep mode during use. What should we do in such a situation?

Solution to the problem of not being able to wake up after computer sleep:

One, in our newly installed Win7 system, the system default is no sleep mode but only sleep mode, at this time in the ‘Power Options’ ‘Sleep’ option, there are only two options to choose from.

Two, if you press the power button on your computer now to wake up the sleep mode of your win7, then it will either not wake up or automatically wake up. What we need to deal with now is how to wake up the WIND7 system. The way to enable sleep mode is to press WIN R, that is, to open ‘Run’, then enter ‘powercfg-h on’, confirm, at this time a dialog box will pop up, and your sleep option will be enabled. Go to ‘Power Options’ and check, whether there are already two options as shown in the figure, a total of four options.

Three, the following is a crucial step, click on ‘Sleep’ in the ‘Allow hybrid sleep’, then select ‘Enable’, and finally confirm.

Note::

1. The method described in the text is not the only reason for the inability to wake up from shutdown and sleep mode in Windows 7, for example:

The advanced battery management settings in BIOS may also affect the wake-up issue.

Hardware shutdown issues or heat dissipation problems during shutdown and sleep mode can also cause overheating and hang, making it impossible to wake up. Of course, the hang situation does not necessarily reflect as a blue screen on the computer.

I have encountered a situation on a friend’s laptop where only the SATA driver of Windows 7 itself works without any problems, and installing AHCI will cause shutdown to hang: (, but it is definitely necessary to install it on my own laptop.

2. The driver update issue in the text is not suitable for traditional ATA computer hard drives. Installing AHCI drivers for traditional parallel port hard drives can cause blue screen issues on the computer.

Before installing, please first upgrade the patch to the latest version, install all drivers with the default settings of the applications installed on WIN7, and first check if the shutdown is still stuck. If it is still stuck, change it.
