Took out battery from laptop and plugged it in the whole time -- is this safe?

I am not actually an expert but I would tell you that it is just normal for the laptop to heat up while it is plugged in. I use my laptop more than 5 hours every weekdays and more than 8 hours during weekends. It would not be good for the battery if I use it while it is currently charging and I don't have any choice because I need it in my work. What I do then is just what you do. I took out the battery and directly plugged the computer to the outlet directly. I've been doing this for like almost 2 years and my computer is still fully functional. The risk though is that the computer will automatically shut down once the power supply is taken out. This would happen if there would be power outage or perhaps you accidentally unplugged the laptop from the power outlet. If such is the case you may lose data that you haven't saved on the PC especially if you are currently working on a project.

Computers heat up - whether on battery or AC. It's normal. Overcharging doesn't normally occur on all batteries. It happened more often with the older batteries (Nickel-Cadium - also known as Ni-Cd or Nickel Metal Hydride - also known as Ni-MH). These batteries needed extra care. The manner of charging and discharging the battery was important. Most comuters are now fitted with Lithium-Ion batteries, also known as Li-ion. These batteries are more expensive. There is an internal circuit to stop the charging process at full charge. The only way for a Li-on battery to overcharge is if the charging system malfunctions.

Actually, I had never really thought of this, so I found your question quite interesting. I normally only use the battery when traveling and when I am at home always plug my computer into the wall socket. This is just routine for me and I've always done it. I've never had a battery fail because of this or for any other reason. Good to read other perspectives on this.

I have been for the most of my computer use have not attached my laptop battery when I am using my laptop. I do a lot of presentations since my job is conducting trainings. My laptop is directly connected to my power supply. I am actually afraid that my battery might be overcharged so I decided not to use it when I am conducting training. Well, I have never encountered any problem ever since. So I think there is nothing to worry about. Naturally when you use the laptop, it will surely warn up most especially that it has a very small fan as compared to the desktop. You should avoid lancing your laptop on any soft surface such as bed, pillows as it may restrict the ventilation. This will surely damage your laptop later on.

I have been using my laptop on the plug for years. I find I bothersome to have the battery plugged, remove the A/C and plug the A/C again whether battery is at the low level. I do plug my battery once n a while so that I know the condition it it has been. Also, I do this to make sure that I have spare power when the power is out. I believe that it makes my battery life more lasting and it serves the purpose of the battery which is for mobile purposes only.

I have tried to do this in highschool, because I don't want my classmates using my battery, so when they try to borrow laptop from me, they have to plug it somewhere. I think it's safe, because our laptop is still working just fine til now. :D

Laptop with battery is basically used for mobility purpose and I would suggest not to use damaged or malfunctioning batteries since that may damage your laptop. Also advised to use power supply with un-interruption to avoid HDD damages.

I do this all the time. I think plugging in WITH the battery still in the laptop is a whole lot more dangerous as opposed to plugging it in without any battery. You're right, the battery has a tendency to overheat and in the long run, it might even ruin the battery life. So, do what you have to do. I've been doing this "routine" for three straight years now and my laptop still works like new :)

Hi, As long as your wall outlet give enough voltage without fluctuations, your laptop would do fine. The heat is normal for most models, it needs some cooler to mitigate the temperature though, especially when the ambient room temperature goes up. If you use the laptop PC-powered style (you lose the mobility), you should consider plugging the power adapter to a continuous power supply system (UPS) first to prevent that annoying power outages and surges that can damage the HDD in the long run, losing valuable data and expensive equipment.

Hello there jure. I am not an exper but I would like to share that I do not put the battery of my netbook here at home. I just plug it directly. Battery of netbook or laptop are expensive so I do it that way. I just put the battery if I need to bring my netbook outside

Actually, it's like this. It is better to use the laptop battery only when like there's no electricity. Of course, you have to fully charge it first. Otherwise, just use your laptop, without battery inserted. In other words, you just use the cable. That is just my advice for your information. By the way, for your that problem, I'm sorry, I don't have any solution yet. If I had one, I'll let you know. At the meantime, I hope someone else can help you.

Obviously it is not safe especially when you live in a unstable power supply region,if it out of electricity then it will damage your laptop. And my opinion is very simple,why not to buy a new battery?I mean you no need to buy a original battery because it is very expensive you can buy a OEM one.It can be used as well and much cheaper.

Just a friendly tip , buy a branded battery and not a low cost battery. Branded is bit expensive but longer life span and not hazardous .Whereas if low cost maybe cheap but it is just disposable and so dangerous that it might explode because of low grade materials being used.

It's actually a good thing you took out your battery. Plugging your laptop with battery in it will cause damage to your battery and they are very expensive. To avoid overheating, buy a cooler pad for your laptop.

I not experience of this because I remove the charger from plug after completing the laptop charging. But I think full time battery plugged it not good.
