Is Sleep Mode bad for PC?
There’s often a concern among people whether sleep mode is better or worse than shutting your PC down. While it is easier to initiate sleep since all you have to do is shut the lid down, shut down helps your PC in performing self-tests, clearing out RAM, and alerting you of software updates.
Does Sleep drain the battery?
Although yes, it does consume battery while it is in sleep mode, it is quite minimal. In the sleep mode, your PC is in a low power state where power is used only to keep the computer’s state in memory. The startup post-sleep is very quick but that snappy power back move takes in a considerable amount of power. We hope this helps!
