Is hibernation the same as sleep mode on my Lenovo laptop?
No, hibernation and sleep mode are not the same. Sleep mode puts your laptop into a low-power state, allowing for quick access when you wake it up again. In this state, your session is stored in the RAM, meaning that power is still consumed. On the other hand, hibernation saves your session to the hard drive and completely powers down the laptop, consuming no power at all.
Since sleep mode allows for a faster wake-up time, it is typically used for short breaks, while hibernation is more suitable for when you won’t be using your laptop for an extended period. Understanding the differences between these modes can help you choose the best option depending on your usage patterns and power management needs.
What should I do if my Lenovo laptop is stuck in hibernation?
If your Lenovo laptop appears to be stuck in hibernation and is unresponsive, the first step is to perform a hard reset. Disconnect all peripherals and turn off the laptop by holding down the power button for about 10 seconds. This should force the laptop to shut down completely.
