Question

Does my laptop battery drain when it's sleeping?

Answer 1

The purpose of "sleep" or "hibernate" is to do a couple of things. First it keeps your RAM (Random Access Memory) running so when you reboot what every you had running before you turned it off will come back up. Secondly "Sleep" keeps the cpu (centralized processing unit) running at a low energy level. "Hibernate" does the same thing but a much lower level giving you longer reboot time. So to yes "sleep" and "hibernate" do take up power. The only time when you should use "sleep" or "hibernate" is when you want to continue something you were working on before you have to leave it. Other than that its best to Shut it down. It also extends the life of your components in the long run.

Answer 2

Sleep mode will use a little power, hibernate will use none.



RAM is where all the data you are working on is stored. In order to hold data, it needs to have power. So sleep mode is where the computer turns everything but the memory off to save battery life and allow you to power up the laptop quickly.



Hibernate writes all the data that is in the RAM to the hard drive, which does not require power to hold data. This will allow you to power up the laptop quicker than from a cold boot (completely powering it off) and it takes no power.

Answer 3

Basically, sleeping puts the computer in to a LOW POWER STATE. This means it DOES drain the battery, but normally it will last for a few hours (maybe 7). When your computer gets to its critical/reserved battery level, it will automatically hibernate. Hibernate saves your current computer state and saves it to your hard drive, then it shuts down your computer. When you boot the computer, it will start from where you hibernated. I hope this helps you.

Answer 4

well yeah. but still battery is gonna last long and hibernate uses less battery power and shut down doesn't use the battery at all. so probably shut down is the best option.

Answer 6

Shut Down vs Battery: Least battery usage. ALMOST None, but there is still SOME Drainage of power. It even happens with TVs that are off and plugged in, no big deal...



Hibernation vs Battery: Somewhat like shutting down, just saves the current status of your system. but Startup is a hell of alot fast (Still shutdown every now and then.)



Sleeping vs Battery: It puts your current session in memory and sets itself into a low power state so the you can almost instantly resume working, but it doesnt shut down, so it is no alternative to shutting down or hibernating.



What I do is Hibernate when going to do something else, and Shut Down when going to bed.

Hibernation vs Shut Down :Pretty damn close comparison....

Answer 7

Ever seen a desktop be in sleep mode while its not connected to a power source? no??? then yes it is draining power, however little it may be.



depending on your circumstances, be profficient with energy use and dont keep it in sleep mode if you're flying from LA to Dubai.

Answer 8

yes just shut it off given that is not nearly as much but yes

Answer 9

yes but it will take like weeks to do dead

Answer 10

Sleep uses the battery a bit.

The advantage is it resumes where you left off and is fast to start using.

The disadvantage is you can loose unsaved work if the battery goes flat or something goes wrong during resume. Also if the battery goes flat when it is sleeping you cant use it when you want to without a power source.

(Note: it is possible for a sleeping notebook in a carry bag to overheat and be damaged)



Hibernate does not use the battery.

The advantage is it resumes where you left off and is fast to start using, but not as fast as sleep.

The disadvantage is if something goes wrong during resume then you can loose unsaved work.



Shutdown uses no battery

The advantage is the computer starts afresh so can be more responsive compared to a computer that hasn't been shutdown or restarted for a few days.

The disadvantage is it takes time to boot, and if you forget to save work it is gone for sure.



Hope this helped

Answer 11

The battery will not drain when it's sleeping or hibernating. I would suggest you hibernate rather than sleep. If you put it on sleep for to long it will heat up. For long periods of time shut it down

Answer 12

Your battery will drain either way. However, there is significantly less battery drain in hibernate mode, as the computer preserves the system memory and goes into a very low-power state.

Answer 13

thinking until eventually it really is amazingly energetic RAM does not take a lot in any respect (just about not some thing) it really is extra likely the battery is failing. often it truly is from not cycling means wisely. yet they don't look to be the most good products of equipment besides. you should objective placing it to droop to disk in stead of RAM, quite often this does not take plenty longer to commence on waking. I often locate it complicated to degree the version.

Answer 14

Yes.It drains even when completely off



All batteries lose power even while sitting around

Answer 15

Don't forget to leave it plugged in that it should drain when plugged into a receptacle.
