My first laptop was an old IBM Thinkpad (back when they were made in the USA). It remained on my desk plugged into the power source from 1999 to 2004. I only powered it down maybe four times.
We have dozens of notebooks that are left powered 24/7. Thay are just fine (Dell, Apple, etc).
If you own a cheap Tiawan brand like Asus, then you might have something to worry about, but even in that case the odds are small.

no it wont
2015-12-06 11:32 pm
it shouldn't be harmful at all. If is was, there was a problem with your laptop. I leave mine on and plugged in all of the time.
2015-12-08 12:58 pm
In short no problem, some people have used laptops as cheap web servers so they are on 24/7 for months. It is designed to run quite happily for ages. The only down side is that you will loose a tiny percentage of battery life the longer its in the mains dependant on how the charger works.
But no, not a problem

no.

This should cause no problem at all. That's what the "sleep mode" was introduced for. There are times when I am pulled away from my laptop for 8 plus hours, and after a couple of hours of inactivity, it goes to sleep by shutting down. Ironically I just discussed this with a computer repair shop technician a couple of days ago. he told me that people really should leave their computers on, either desktop or laptop, for as long as three or four days before powering them off to clear the cache/RAM every now and then. This is especially true over Tuesdays when the Windows updates are released. He said he rarely ever shuts hos computers at home down and has had no problems with them when leaving them powered on. Other than the fact we're wasting a bit of electricity when the computer is on and not being used, he claims this is easier in the long run than powering the unit on every day or even several times daily.

Leaving a Laptop powered on for long periods of time will present no issues as long as the Laptop has adequate cooling.
I have 4 laptops of various different ages and I leave them on 24/7... Powering on and shutting down causes more wear and tear due to cooling and heating cycles, whereas leaving on continuous, while being less energy efficient is less stressful to the device.

2015-12-09 6:29 pm
The laptop will be fine. If you have sleep mode enabled it will automatically go to sleep. However even if it was left on for 2 days straight it would still be fine. These machines are designed to run continuously.
2015-12-09 3:00 pm
There shouldn't be a problem with your laptop, even if you left it for more than 5-6 days.
2015-12-08 7:03 am
no, not at all.
2015-12-08 1:56 am
No. It will cause normal wear, but that's negligible after only two days.
2015-12-07 10:13 pm
It wears off the battery's life slightly, but you shouldn't worry about it. Even if you turned off sleep mode
2015-12-07 9:22 am
no
2015-12-07 12:01 am
No.
2015-12-07 8:43 am
it may cause the release of underground CHUD. I'd be worried.
2015-12-22 11:15 pm
Idk
2015-12-22 10:14 pm
No. I am using a laptop from the past 6 years and haven't experienced any such troubles. I keep the charging plug in the socket of my laptop always and it did not damage its potential or work functions in any way.
2015-12-22 6:03 pm
Gennarally it will not harm, because It will sleep or hibernate as the configure of Power management.
Also is there a good battery , the lap ac adapter will be stop charging after full charge, and after start sleep mode it will cool down. not harm, but if you configured it will make over heat and stop.

OMG, 2 days with it plugged in! Call the authorities, get rid of it! It's no longer safe!! RUUUUUUUNNNN!!!!
2015-12-20 2:58 am
nope, it won't be any damage unless you keep it charging for a month. I have tried continously charging my laptop for over a week and there isn't any problem
2015-12-19 10:59 pm
It shouldn't I have an HP 15 notebook pc and it stays plugged in all the time except for the few hours every week when I take it somewhere and its been perfectly fine
2015-12-18 1:29 pm
You have got quite a few answers, I can't go through all of them so I don't know if someone else mentioned but here is what I think:
I had to open my laptop multiple times to remove fluff accumulating where the fan is blowing the heatsink radiator of the processor/CPU and the GPU.
I mean the laptop was unusable it would overheat in a matter of minutes and the safety system would turn it off to save the CPU.
So you are certainly helping fluff accumulate.
I also have my laptop connected to the mains through a protective device (it's not a UPS it has lightning protection, overvoltage protection, undervoltage protection, thermal protection and I think it filters transients) so should something happen it has some chances of survival but nevertheless I don't leave it on like you did.
And should power goes down for long period of time your laptop may get its battery discharged.
Batteries are designed to be charged and discharged however I recently read that extreme charges and discharges shorten their life.
They are compared to a spring and the greater the deformations the more likely it is to loose its properties.
So I don't know how to limit the amount of charging your battery is charged to however you can do something about preventing deep discharges.
Now I use my laptop as a desktop computer and use its battery as a UPS only, and if you use your laptop as a mobile computer and need the greatest capacity the battery can provide you then you have no option but to fully charge it and deeply discharge it, unless maybe if you can afford to buy an extra battery and a charger for it so you switch the batteries and continue working however some computers require the battery changing to be done when they are turned off(not in stand by regime).

2015-12-17 4:32 pm
It can lower the battery capacity by few mAh-s but even normal usage will do that.It was just sucking and wasting it.So I would rather worry about bills and that still isn't any problem
2015-12-17 4:56 am
SHOULD DO, I MEAN HOW CAN U NOT NOTICE IT OR USE IT after not turning it off... insane and careless child! Learn to spell.

Nope. If your laptop has heat issues then the screen will dim.
2015-12-16 10:38 am
don't know enough about the technicalities to give advice -
however it doesn't seem to have improved your spelling.

2015-12-16 3:04 am
it doesn't harm. Because in this case the power is automatically cut off when it's become 100% charge
2015-12-15 3:05 am
It will damage your laptop charger.Since your lap was ON for two days,it might drain up ur battery or may cause screen burn. But none of them happened..it means your lappy is 100% safe.in this case,direct power is taken by charger,all the load nd loss should be expected in charger...power delivered to ur laptop is limited to some volts...so it will be safe for sure
2015-12-14 4:34 am
I don't think there is anything to worry about. The laptop is fine. As there is charge controller there is no way to overcharge the laptop. So it's safe
2015-12-14 3:31 am
In most cases it won't cause any damage at all
2015-12-13 3:12 pm
nah ı always keep my laptop plugged in u are fine
2015-12-13 7:42 am
I really don't think so
2015-12-13 5:32 am
Yes, it will overheat then eventually melting soon. I think you got rekt mate
2015-12-13 3:06 am
nah
2015-12-12 9:22 pm
At this point do u really think that tech is that fragile some people are afraid that their phone charger will burn their house down iv had mine plugged in for the last 2 years your pc is fine
2015-12-12 11:52 am
I used to wonder about that too. I asked a computer person once. He said that it's good to unplug the charger once it reaches 100% as it puts pressure on the battery. I get very attached to my laptops and only replace them if they die. Prior to replacing them I may buy batteries from time to time. This is probably what leaving the power on and plugged in will cause you to need to do. The battery will get weaker- however batteries can be replaced.
2015-12-11 7:49 pm
i just need points i dont give a **** about it...
2015-12-11 3:26 pm
don't think you gonna face any problem but if please do some care and shut down your pc while you are not working ..if you regularly keep doing such thing your battery backup will go down
2015-12-11 9:15 am
it may cause your laptop battery to explode . generally if you overcharge your battery whether its of mobile or laptop it explodes or otherwise go dead
2015-12-11 4:06 am
no it fine
2015-12-11 1:19 am
Computer hardware is designed to run 24/7/365 .. Just ensure proper cooling and light workloads(internet surfing,movies,file copying,etc). I keep my desktop & laptop always on.

2015-12-10 8:47 pm
Shouldn't be a problem.
2015-12-10 5:59 pm
No, its good. My Toshiba Workstation remains on and plugged in all the time, even when idle. You will be fine. :)
2015-12-10 1:26 pm
no i do it all the time
2015-12-10 9:51 am
It will not cause any major problem but shorten it's battery life.
2015-12-10 8:16 am
No, shouldn't have caused any problems at all, I leave my laptop on 24/7 all year and it's fine, it actually seems to work better the longer it's left on for.
2015-12-10 7:53 am
It will be fine as long as you don't let it happen all the time. And even then all that wil happen is you will wear out the battery
2015-12-10 4:39 am
2015-12-10 3:20 am
probably not
2015-12-10 2:56 am
yes

2015-12-09 9:32 pm
How can you forget?
2015-12-09 7:05 pm
It might, if a laptop and a tablet are related.
2015-12-09 1:23 pm
no....
2015-12-09 6:42 am
No problem, just don't make a habit of it.
2015-12-09 4:39 am
You will certainly see no problem but a short decrease of battery life. And as this is not a too big difference, do not worry.
2015-12-09 2:25 am
as the others answered it will go to sleep mode unless you have adjusted the laptop to stay on all the time.generally speaking ,no problem.
2015-12-08 11:55 pm
If its a newer Mac than no. Most Apple specialist claim that the computer will stop charging when it reaches 100% Depends on the type of computer... Is it a Mac/Dell/Acer/Etc....?
2015-12-08 4:51 pm
Calm down....
It's fine
It's fine
2015-12-08 2:03 pm
It might not good for the battery of the laptop
2015-12-08 9:02 am
relax, it is fine.
2015-12-08 8:58 am
no its fine if it's working now. Worst thing that can happen is you ruined the battery a little
2015-12-08 4:08 am
No its fine, Laptops will stop charging on there own. I have a desktop and i leave it on 24/7.
2015-12-08 4:05 am
yes
2015-12-08 3:04 am
If your laptop didn't go into sleep mode then maybe because of what might get burned into the lcd, or because the system itself may have gotten hot. But if it did go into sleep mode you should not have anything to worry about. A little wear on the battery is probably the only thing that occurred.
2015-12-08 2:44 am
youll be fine
2015-12-08 1:05 am
you computer should not be damaged in any shape or form, in fact computers actually like to be on
2015-12-08 1:02 am
Nope
2015-12-08 12:21 am
nothing
2015-12-07 8:59 pm
????????
2015-12-07 6:41 pm
No it wont cause any problem at all but still best to turn it off when not in use.
2015-12-07 5:10 pm
Nope. The laptop automatically switches to sleep mode. However if there is any power fluctuations then it may effect the battery.
2015-12-07 2:19 pm
Mine is powered and plugged in for many days on end. It doesn't cause damage, but it does wear your battery out quicker.
2015-12-07 2:10 pm
I have indeed covered some of this before, once or twice, but your question is timely: Just last month, your fine state adopted new energy-efficiency rules for chargers, citing potential residential and commercial savings of $306 million a year. Also, I am all zinged up by your question about leaving chargers attached to gadgets when their job is done — an important, but often overlooked, variable in this multi-pronged energy equation.
First, a refresher on things that plug in, which allows us to bandy about two fun terms. “Vampires” are appliances that suck energy even when you think they’re shut off, like microwaves, DVRs, TVs, and game systems. Anything with a cute little light or digital clock on it is drawing power, usually unnecessarily, and costing you money — one estimate from Cornell University suggests these vampires cost an average household $200 per year. Unplug these items when you’re finished with them, or better yet, use a power strip.
Our other offenders are “wall warts” — a nose-wrinkling term for those chargers with oversized, boxy plugs — and other AC adapters. In a national display of incomprehensible laziness, these power supplies are often left plugged in when disconnected from the gadget in question. It’s as if you decided to pour yourself some orange juice, filled up the glass, and then just left the jug lying on its side, the top off, contents spilling everywhere. Why, people, why?
My tidiness issues aside, it turns out there’s only one thing worse than leaving a charger plugged in with no device attached: leaving it plugged in and charging for too long. Now, T.G., we get to the heart of your question, but we must travel along slightly divergent arteries to discuss your phone and computer.
According to our very thorough, very reliable friends at the Lawrence Berkeley National Laboratory, who measured several devices in each category, a cell-phone charger draws an average of 3.68 watts when the phone is on and charging; 2.24 watts when it is on and charged; and 0.26 watts when it is just hanging out in the socket. So put very simply, leaving your charged phone attached to the charger uses 10 times the energy that leaving the charger dangling would. None of this amounts to much on its own; the Berkeley Lab people estimate that each watt they measured translates into roughly $1 per year of energy expenses, so we’re talking about $3-$4 per charger, per year. But when you consider all the chargers in your house, then multiply it by the 115 million or so households in the U.S., it adds up.
Your laptop follows a similar-but-higher-stakes pattern, drawing an average of 44.28 watts when it is charging; 29.48 watts when it is charged; and 4.42 watts when we let the charger dangle. Laptops get a bit more complicated, because keeping them plugged in can actually be a good thing — it’s more efficient to use that power to run the machine than to use it to charge a battery which then runs the machine. So if you’re going to be stationary for any length of time, consider keeping the machine plugged in (be sure to check your manufacturer’s recommendations, as they do vary). Also, ignore people who try to scare you about having to charge, discharge, and recharge your battery; today’s lithium-ion models do not need such handholding (here are a few tips for making your Li-ion battery last).
T.G., if you’re feeling forgetful when it comes to your chargers, I have a few ideas:
Create a central charging area for all the devices in your house, using a power strip (with a timer, even) to ensure that nothing is left on longer than needed.
Check out alternative chargers like wind-up or solar devices.
Buy a watt meter, which can be had for $20-$40, to see how much energy you’re using around the house, and how much it costs. (To give you a sense of scale, many users report that dangling chargers use so little energy as to not register on these meters.)
When the time comes to buy new electronics, look for the Energy Star label.
Frankly, I’m of two minds about whether we should all freak out about chargers. Standby power use is responsible for an estimated 1 percent of global CO2 emissions, and every little bit certainly counts. But if you haven’t taken bigger steps like insulating your house or embracing public transportation, fretting over wall warts might not be the best use of your energy.

Most probably there will be no damage because your laptop would have been gone on sleep mode. So no need to be worry about that.
2015-12-16 11:45 am
I think; it does not an issue of any damage. And, I discuss about battery power saving processes.
1. Reduce the brightness of laptop screen
2. Prevent updates when laptop running on battery power
3. Unplug unnecessary devices
4. Turn off Bluetooth
5. Set the Power Plan
6. Use InstantGo technology

2015-12-10 9:22 pm
well, I don't think that's a good idea it might cause battery damage, and laptop batteries are expensive
2015-12-10 1:37 pm
The laptop I'm on is five years this month. From personal experience, I haven't found any damage to battery or screen when left on for more than a few days at a time. I do have it set up to go into sleep mode, though. When I know I'm going to be away from my computer for awhile, I also turn the screen brightness down. Also, since seeing that piece on how some hacker may be able to turn on the webcam, I lower the lid down so it's pointing downward. I also have it plugged into a battery backup/surge protector.
I suppose I may have shortened the life of my laptop, but for me, I feel five years of problem free service is worth the money I paid for it. (HP Pavilion dv7 series AMD processor 17" Entertainment Notebook running win7)

Don't Worry the laptop will go automatically to "Sleep Mode" unless you have change the settings in the Power
Option.
I use to switch off my Laptop once in a couple of Month for dusting the table. I have not seen any performance hamper.
So Chill don't Worry..

It can ware down the battery life and could burn out the screen, otherwise it shouldn't be too much harm as long as this isn't a frequent thing to happen.
2015-12-08 3:13 am
I've left mine powered on and plugged into power 24/7 for many years.

It could damage it, however, the most damage would occur to the battery and screen (assuming it wasn't closed).
2015-12-07 8:58 pm
This is a sure fire way to overheat your computer and that is definitely not a good thing. I would not be surprised if you begin to have problems with your computer.
