Artificial intelligence researchers tell me this is a bad idea. If you’re not using your laptop at all, then it’s cool. But if you’re doing something else with it which involves charging then nothing is happening – the CPU isn’t running, there’s no data being transferred to or from HDD, etc. The battery will never charge in that case because the power supply has no work to do too!
This may result in a non-working battery. So it is not good to keep your laptop on charging all the time unless you are in hibernate mode or sleeping mode where your machine is on standby. If the machine has been switched off and you have been using a mains supply then it’s fine to leave it charging overnight without any problems.
You can find out more about how power management works by reading this article. In general, though, it is not advisable to keep your laptop plugged in all the time as you will be exposed to a number of risks.
The first risk that you run is that there is a chance that your laptop will overheat – especially if it is kept in an enclosed space such as underneath a pillow or under a table etc. This overheating may cause damage to components or even start fires if precautions are not taken. Even Apple – whose are known for their sturdy design – has suffered from this. It is not uncommon to find videos on YouTube showcasing their prized possession being reduced to ashes in seconds.
The other risk is that you are actually draining the battery unnecessarily when you keep your laptop plugged in all the time. This will also lead to a reduced lifespan of the battery due to constant overcharging. To help reduce power consumption, laptops have features built-in which dynamically adjust power levels based on usage patterns. When your laptop goes into idle mode, the processor clocks down, and less power is consumed by it – thereby reducing heat generation too. If you leave your laptop plugged for a long period of time, then chances are that it may be idling most of that time thus creating excess heat and wasting energy (especially if it is a desktop replacement).
There are laptops that have either a battery management system or a hard switch that will disable charging. However, all this does is keep the battery from getting charged – it does not actually stop it from discharging – both when plugged in and not plugged in. The only way to completely stop the discharge of your laptop’s battery is by physically removing it (if you can). If you do not want to go through that much hassle, then we recommend shutting down your laptop and unplugging it – once every couple of days.
Is it fine to charge your laptop while it is shut down?
A few years back I used to read a lot of articles about how it’s not a good idea to charge your laptop when you shut down your computer, that the battery would be affected in some way. I’m wondering if that advice still holds true today? It seems like most people suggest charging while on or turned on. Thanks!
It is perfectly fine to charge your laptop while powered down. Do you know how sometimes when you leave something plugged in too long without using it, it starts running slowly and acting sluggish? That doesn’t happen with laptops– unless they’re improperly calibrated (e.g., dimming the display) or have some other problem that can be fixed through calibration/cleaning/hardware maintenance.
As long as the battery is healthy and maintains a charge, there’s no other reason your laptop should slow down or run sluggishly while powered off. I’d be more concerned about draining the battery before you get a chance to recharge it—and if that happens while powered on, then yes– you’ll risk a sudden crash.
You’re not harming the battery by leaving it plugged in overnight. The worst thing that can happen is that you’ll waste electricity if you leave your computer charged for days on end.

Is it safe to keep my laptop in sleep mode?
Sleep mode conserves a computer’s energy by turning off some of its components, including the display and hard drive while keeping others—keyboard lights, memory, and wireless connectivity—on for quick access. When you open your computer again, you only have to wake it up rather than go through a full boot sequence. Your laptop uses some power even in sleep mode because certain components stay on—but this shouldn’t drain your battery completely or constantly. In fact, most laptops can last up to 30 days in sleep mode.
Do I need to be worried about my laptop in sleep mode and is there anything that can damage the computer?
Basically, if your computer is not receiving any interruptions while it’s in this state, you don’t have anything to worry about. Just don’t close the lid on a Macbook Pro when it’s in sleep mode (the system will wake up when opened). However, you should not shut down or reset your computer without allowing it time for all of its files to be safely written back to disk. These temporary memory areas are called “swap space” and if the system is forced to use them after their contents have already been back into virtual memory (typical of swap space), then data loss is likely.
It’s always best to do a proper shutdown (including selecting the proper option in Windows) when you plan on leaving your computer alone for any period of time (say more than 5 or 6 hours; some experts say it’s okay if you leave it overnight). This clears the memory completely and allows your operating system to complete all pending tasks before exiting. If you’re not sure how long you’ll be away, just give it at least an hour after logging out of Windows before turning off your computer. Of course, this also applies to laptops that are plugged into the wall at all times—most users don’t realize that they can unplug them while working on something important! So, to sum them up, some precautions you should take:
Never leave your computer running while unattended. Have a routine of saving your work and exiting all programs before going to sleep at night. If you want to watch a DVD or listen to music, make sure you allow plenty of time beforehand for the disc to load and the program(s) to launch. Never close the lid on a Macbook Pro when it’s in sleep mode (the system will wake up when opened). However, you should not shut down or reset your computer without allowing enough time for all files to be safely written back to disk – these temporary memory areas are called “swap space” and if forced into using them after their contents have already been written back into virtual memory (typical of swap space), then data loss is likely.
If you have a desktop computer, never cover the fan vents with anything. This impedes proper cooling and can lead to a heat-related failure or fire hazard. It’s probably a good idea not to eat or drink around your computer too! If it is in sleep mode when the power goes out, there shouldn’t be any problems, but if they’re in hibernation when the power fails – well, you get the picture. Remember that all devices need room for air circulation and there are no exceptions to this rule—including notebook computers that use an external monitor when placed on a desk with a separate keyboard and mouse. If your laptop is in a carrying bag, make sure that the vent at the bottom is not blocked before calling it a day.
Also, it’s very important to know that even when you’re using your computer, if it’s generating heat due to overclocking or other reasons (like working too hard), you should set up an automatic shutdown schedule so that your computer can correctly recover from any damage caused by overheating. Finally, never let your laptop run on battery power for extended periods of time if you want to keep both the battery and system in good health. This is especially true with older model laptops—you can check this tutorial for more details.
Does putting the laptop in sleep mode cause damage to RAM in the long term?
It is quite common for people to put their laptop in sleep mode when they are not using it. This saves energy and prolongs the life of the battery. However, some users have also claimed that putting a computer in sleep mode can cause damage to your RAM. So let’s look into whether this is true or not.
First of all, let’s look at how RAM works. When you start up your computer (or restart it), the first thing that occurs is called “booting”, where your operating system is loaded by temporary storage (usually on hard disks) known as ROM BIOS (Read Only Memory Basic Input/Output System). The RAM will contain function pointers that point to where the operating system is located on the hard drive.
Once the operating system is loaded, it begins to load drivers for all of the different hardware components in your computer (eg. graphics cards or network adaptors). It also allocates space in RAM for these devices, so that they are ready when you want to use them.
Now let’s talk about putting your laptop into sleep mode. When you put your computer into “sleep”, RAM will no longer be powered on. This means that any device which was using this memory will lose power and will thus be reset (and therefore lose any information which had not yet been written to non-volatile storage). These devices include network adapters, sound cards, etc… So if you use a wireless keyboard or mouse while your computer is in this state, you will have to re-pair the devices when you turn your computer on again.
What about RAM damage? Once the memory has lost power, it cannot be powered on again without something to tell it what function it should carry out (because all of the information is stored in non-volatile storage). If there is no device that needs access to that memory, then there is no way for it to get power and thus no reason for the data to be retained.
For example, many laptops actually come with a small hard drive inside them which acts as an additional battery pack for keeping some information available if the main battery drains completely. This hard drive remains functional even when your laptop loses power. Although putting your computer into sleep mode will eventually cause your RAM to lose power, it is not able to hold a charge long enough for this information to be lost. You can read more about how RAM works here.
What you should do: As we mentioned before, putting your laptop in sleep mode does not cause permanent damage to your RAM and thus there is no reason to avoid doing so. It also saves energy and prolongs the life of the battery (although the main reason why laptops enter sleep after they have been inactive for a certain period of time is that it is most useful when the laptop isn’t actually being used).

How long can we keep laptops in sleep mode?
Most laptops will go into sleep mode after the computer has not been in use for about 10 minutes. This is to conserve battery power and keep your laptop ready to provide you with all of its resources at a moment’s notice. Many people believe it is fine to leave their laptop in sleep mode when they are done using it for short periods such as taking a quick break or finishing up on one task. The problem with this comes from when people do not allow their devices time to ‘rest’.
If you like, you can think of sleep mode like an athlete going through practice drills and conditioning each day before his real games begin. If he only practices well but never plays full games, then things start getting out of shape and he gets tired faster. This is a lot like computer components when they are in sleep mode but not being used. While the electronics get to ‘rest’, the components (such as your hard drive, display screen, etc.) will get out of shape and strain your laptop’s components if you do not allow it some time to use each day doing full tasks.
** What can happen? **
If you’re lucky, then nothing may happen and everything continues working correctly for quite a while (with problems only occurring every now and then or after heavy use). However, there is always a chance that something could go wrong with your device which may result in an overheated battery, reduced battery life, reduced processing power due to overheating, and potential problems with your hard drive and other components.
** What can I do? **
Ideally, you should let your laptop come out of sleep mode daily to give it a chance to use and rest like we were discussing above (this may be by simply allowing it to sit for 10 minutes without opening any applications or performing any tasks). This should help to avoid any problems that might arise from leaving your device in sleep mode for too long. You could also try closing out of all open programs before allowing your computer to enter into sleep mode as this will allow the device as well as the battery’s power usage time to adjust itself accordingly.
