Such a problem - the computer does not wake up from sleep mode or takes too long - is not so rare. To solve it, in most cases, it turns out to be sufficient to make a number of simple changes in the settings.
A possible reason for this behavior of a computer or laptop with Windows7 installed is the programmed disconnection of the hard drive from the power supply after a certain time in sleep mode.
By default, Windows7 is configured so that the hard drive is disconnected from power after 20 minutes from starting in standby mode. Problems may occur when trying to turn on again. To avoid such problems, it makes sense to disable the power off function of the drive.
To do this, you need to do the following:
1. From the Start button menu, select the Control Panel folder. In the control panel window go to the "System and Security" section. In this section, select the Power Options tab.
2. Under Power Options, select the Change Battery Options tab. The Select Power Plan window opens. Here the "Balanced" plan is selected by default, leave it that way. Go to the Balanced Plan Power Plan Setup tab.
3. In the window that opens, go to the "Change advanced power settings" tab. Select the line "hard drive" in the drop-down list, then "unplug hard drive after". Left-click on the set time value in minutes, in the window that opens, select the "Never" value. Click OK.
After this configuration change, the hard drive will no longer be disconnected from power, which will speed up the time the computer wakes from sleep mode.
