why sleep mode without backtosleep is not safe?
If you keep your laptop in sleep (standby) mode you have to know that your computer may unpredictably wake for multiple resons:
1)External devices like USB keyboard or mouse may awake your PC. Bluetooth or LAN adapters, modems and other devices can send command wake computer from sleep mode too. Read our guide how to stop mouse from waking computer.
2)Operating system itself and even any thirdparty software may wake your PC on schedule. By default Windows Update will install updates at 3 a.m. Any software may add itself to system scheduler which will wake PC to run the task. Read how to stop software from waking computer.
3)Power button of your laptop may be pressed accidentally in carring bag. Lid opening sensor may activate when your laptop is moved. There is no known alternative to BackToSleep to prevent this.
