Is it ok to leave the battery charging while it is being use? Or is it ok to keep the power plugged in with full charged battery while the laptop is in use? Can this shorten battery's lifespan?

When your laptop's battery is 100% charged, should you leave it plugged in so any battery power doesn't get used, or will that cause overcharging, overheating, etc.? Should the laptop be unplugged when the battery level is 100%?  I'm asking because my laptop's screen tends to get dim when unplugged, so I don't like to run it on battery.

Answers to this question  explain how charging while phone is in use does both - charging the battery and powering the on going activities.  My question is different — Can I stop charging the battery but use the connected power for ongoing activities?  Why do I want to do this?    I want to charge the battery within ideal limits (see )    and    at the same time use the charging power to keep running the phone without any heat stress on battery, thus extending battery life.  Also the battery is not drained, enabling me to use the phone for longer time without charging   Edit : I am not looking for dedicated cables or hardware that can possibly do this

I wanted to ask, what to do if MacBook Pro 2017 uses more wattage than the charger can give? Why I am asking this or thinking this might be a problem? I tried to play some games on BootCamp (playing games on MacBook is another discussion, no hate please) on settings where I got 60FPS without lag but the problem is that my battery is discharging at the time I am playing. I can not recognize the problem on macOS though.  If I bought the mac couple days ago, first they gave me fake charger which f*d up my mac and wouldn't charge at all. Still can not believe that I buy new Mac and get fake charger with it. Then I went back to the store and asked for new Original charger which I then got. I can not see any more problems than the above I described.  Can anybody tell me what to check, what to do, who to contact with? Any help is much appreciated.

Is there any sort of installation that can be added to provide power options for when I am running on battery? I wouldn't want to always be on power savings, so I would hope I could switch between Eco and performance like I do with windows 7. Anything like this out there?

My laptop battery won't charge anymore, sits at 0%, and the laptop only operates if plugged to the AC adapter (it detects the power cord, but charge remains at 0%) The battery is already 2.5 years old, saw extensive use (at least daily recharge). so I wouldn't be surprised if it is damaged/beyond repair, but could it just be a software issue? I'm running Arch Linux.

The comments in  say that I shouldn't wait until low battery charge level before I charge, because that reduces battery life (this is contrary to my understanding before that the faster we charge (without waiting for battery to discharge) the worse it will be for battery life). My question is, when I should generally start charging to avoid this effect? 20%?   Interesting question: If we always limit the usage of the battery only 20% and above, won't we, in effect, reduces our battery capacity to 80%, because we will only use the battery in 20%-100% state?

I have found contradictory opinions on this. Some say Windows users tend to shut down but that it is not necessary, and I tend to do that too. Others say it is preferable to shut down, as it does not take too much time to boot anyway, and that in this way the battery is protected. While others say that it is in fact better not to shut down to often, including for the battery, etc. An interesting opinion - cannot find the link for that now - was that shutting down / restarting serves no purpose for Macs, except when that is needed after installing or upgrading applications or the system, unlike in Windows, where shutting down was (is?) very important. Also, that Macs do periodical system maintenance work during operation and even sleep, which eliminates the need for restart; possibly restarting would even come against all this, etc., and &quot;not shutting down&quot; is in fact a typical differentiating Mac feature. Is this true? I need a competent opinion on this - not just a description of the most common use - preferably reflecting some advice from the manufacturer. I have a Macbook Air.   Update after answer: Although I got , a crucial point in it (that the system has to be shut down, but only from time to time) is not yet clear: how often should I shut down the system. So, I will bring my question down to this formula. As pointed out by that answer, my question cannot be answered in relation to a tangible benefit for the system, but rather in relation to the battery life. So, I guess this last point can be answered by some information on how how is battery life dependent on how often the system is shut down.

I want to do laptop maintenance and looking to ground myself with an anti-static wrist strap.   How, or where, do I ground myself to the laptop? Where can I find a grounding point in order to not make a mistake and spoil something?

It is a  and the other day it stopped charging.    The charger seems to have some output since one of the LEDs on the battery lights up. It is only one LED though and I believe I remember the other LEDs (in the column of LEDs) light up in a fashion when charging. I only measure 5V of output from the charger which might, or might not mean something. The charger can be so cunning as to output only a low voltage until it has found out a proper Bosch battery is attached and is ready to be charged.  I have tried taking the battery out of the charger and depress the button for 10 seconds as I have been told it resets the battery but to no avail. I have unplugged the charger, waited for some time, and replugged. Nothing is running hot, not battery nor charger.    I am taking both battery and charger back to the shop but before that, is there another trick or check?    For future reference I add what has happened so far: The dealer has software with a license dongle s/he had to buy from Bosch. S/he connected a computer and saw some logs about the battery being too hot (I am certain it has not been) or cold (inprobable) and it being bricked due to hardware failure. S/he saved the log and then resetted the battery. I can now use the battery again. Bosch has commented the error log with "no danger". So Bosch bricked my (very expensive) battery without any reason and then forced me (the dealer) to pay for a solution. That is not serious business.

I would like to get an alert (with sound) when my laptop battery is fully charged.  How can I do that?

I bought the MBP around 2016 April. Few months ago, around 2018 Nov, bottom of the device appears a bit uneven, with slight gap with my desk. Over past few months, it wobbles more and more serious. Today I brought it to Apple Store Singapore for diagnostic, specialist at Genius Bar confirmed that it's caused by swollen battery. Consider it was just after about 2.5 years use, I find it hard to believe. According to the staff, it depends on usage. If under heavy usage or often charge it overnight, it's normal that MacBook Pro's battery can become swollen pretty soon.   My battery charge cycle is under 300, battery life drops a bit but still strong (9 hours instead of 10). I rarely charge overnight, normally turn AC power off and leave my MBP in sleep mode. I do use my MBP heavily though, say 10 to 13 hours a day. However, I still find it hard to accept the explanation given by Apple Singapore.  I wonder if other MBP 15" users experience the same? Or... am I the isolated case?  -- edit  To make the question more specific, is it generally expected that, Macbookpro battery will start swelling after 2-3 years use if laptop usage is heavy, e.g. 10-13 hours a day? The concern is not about the slightly reduced battery life (the battery life is still strong), but the physical expansion. I'm asking this because I've used few other laptops before, among which I never experience battery swelling except one (after near 5 years use). If the experience with my MBP is aligned with most other users, which means it's just a matter that I should adjust my expectation, and include the near SGD300 battery cost per 2-3 years into my next purchaser's consideration; Otherwise, I will try to ask them to consider replacing without me paying the full cost.   -- update 2019/6/21  Apple has just announced a battery recall for Macbook Pro 15" mid-2015 model. They confirmed that these batteries may pose fire safety risk:

Quite similar to . If I'm not mistaken any impulse mobile device charger is still consuming power, when plugged into socket, but when cable is disconnected from charged device. Correct?  Does the same rule goes for power sockets equipped with USB ports for charging mobile devices ( to Polish seller):    I was wondering, if this kind of construction means that my socket(s) will be continously draining power, 24 hours a day, no matter if anything is connected to it or not? Or do these have some kind of power-off "switch" (meaning stops draining power when everything is disconnected)?

On my y510p, I set Lenovos battery software to "Optimize battery health" while I was in Windows 8.1. I forgot to change it before overwriting that partition with Ubuntu, and now my battery in Ubuntu never charges past 59~60%. I think this is due to something in the BIOS because it persists despite my Windows partition being gone.   I've searched the BIOS but there's no mention of battery anywhere!  I'm using Ubuntu 14.04 LTS.

How do I change the low and critical battery levels to below 10%? I understand that this is a reasonable limit for most portable computers, but what about those with large batteries? On my computer (which has two batteries) 10% is an hour of runtime and is therefore way too high.

My friend told me that I need to disconnect the power cord when the battery is fully charged. Otherwise, I will shorten the life of the battery.  Other people say you should drain it once a month or point out that for long term storage, you should charge it to 50% and then periodically (3 to 6 months) bring it back to 50% and store it again.  I am going to use my laptop at home 90% of the time. So, I plan to have the power cord connected all the time.  I'd prefer to just plugging in my MacBook Pro and letting it be on charge long term and occasionally taking it away from the charger when I'm not at home or my desk.  Are these specific recommendations worth the inconvenience?

In the power management, I selected the option called "suspend when I close the lid". If I close the lid, the computer is not suspending. It keep itself on. How can I solve this problem?

I've been experiencing a very annoying problem lately. Often, I've got my MacBook Pro connected to  power when I'm working from the office. At home, I often leave it unplugged until the battery is too low to continue at which point I plug it in. The problem occurs when my device is connected to a power supply. My battery indicator shows 100% charge which is fine. But sometimes the battery starts draining and the menu bar icon says &quot;Battery not charging,&quot; even when it's connected to a wall socket, and it keeps draining until absolutely dry. It doesn't even warn me the battery is running low because it shows &quot;Power source: Power adapter&quot; which I guess disables the Operating system low-battery warning. This has happened on multiple occasions. I've already tried several things, I've swapped chargers, swapped wall sockets, started with as few tools/apps running as possible. But the problem comes back. I also can't really tie this to a specific app or behavior,  AFAIK. Does anyone know what might be causing this behavior and what to possibly do about it?
