How long should a laptop be put on sleep before it should be shut down instead?

Question

I recently got a new laptop (HP Envy m4) & I want to make sure I don't unnecessarily deplete its battery life.

With my old laptop (a -very- old Pavilion dv2000), I only shut it down when I wouldn't be using it at all the next day. I'd put it to sleep almost all of the time. It lasted fairly long, but the battery pretty much died at some point and left it with an unplugged life of less than an hour. I'm not sure if this was due to its age (about 5 years before I replaced it) or me almost never shutting it down.

My question is: at what point (e.g. before bed, gone for a few hours, gone all day ) should I shut down my laptop instead of putting it to sleep? Also, how often should a laptop be shut down in other to maintain is battery life?

Thanks!

Answer 1

Sleep doesn't fully shutdown your pc as you know its something like standby. It still keeps the programs and just saves the PC state for a while but it does consume power.

Machine state is held in RAM memory and, when placed in sleep mode, the computer cuts power to unneeded subsystems and places the RAM into a minimum power state, just sufficient to retain its data. Because of the large power saving, most laptops automatically enter this mode when the computer is running on batteries and the lid is closed. If undesired, the behavior can be altered in the operating system settings.



A computer must consume some energy while sleeping in order to power the RAM and to be able to respond to a wake-up event.



So instead you Hibernate your PC



Hibernation is functionality allowing a computer to be turned off completely while maintaining its state. On switching back on the state is restored to the way it was, with files open, unsaved data intact, etc. Whereas a computer in standby mode has the computer's state saved in RAM, a system in hibernations has the state of the computer saved on the hard disk (swap partition).

depends what you mean by sleep if you mean standby you can leave it a couple of hours if you mean hibernate you can leave it as long as you want if you are leaving your laptop for the day or going to sleep at night hibernate it you don't need to shut it down.

i've been using laptops 12-13 years basically i never shut down my laptop if i'm not going to use it for up to two hours i put it on standby if i'm out all day or going to bed i hibernate it i only restart my laptop when windows wants to automatically restart and install critical updates before automatic updates existed i'd restart when it got sluggish and unresponsive or froze



typically if your laptop has a good battery it can last on standby for a week and hibernate or shut down for a month it is good to drain your laptop battery every now and then the rest of the time you can keep it plugged in older batteries used to have a memory effect and would eventually last less and less time modern batteries don't have that problem

Answer 3

its depend on time:



if you work offen 15 to 45 min you can go with Sleep mode.



if your need not want to shutoff use "Hibernate" option.
