Laptop battery

I read somewhere that it was now safe to leave the battery in charge all the time as they had "safe switch" that made it so that it doesn't charge all the time. So I tried on my ASUS R510C with the ASUS Li-Ion Battery Pack A41-X550A and I guess I was wrong.

The battery is completely dead, meaning that if it's not plugged in it won't work and will shut down as if you pulled the plug on a desktop PC. In fact, it acts as if it has a low Battery life if I leave it inside, even while being plugged in.

I guess it's not safe to do leave it all the time plugged in.
 
What source? I'd RMA it personally. Regulated Li-Ion charge circuits in laptops have been there for over a decade, unless they implemented some substandard one so you'd buy more batteries

@johnb35 hah, it seems like something else is an issue, I've left my laptop plugged in for months at a time without this behavior

While it may not happen to some laptops but it does happen to a good share of them. I physically see at least 2 a year dealing with clients, my last one was just a few months ago.
 
This is not a problem of leaving laptops plugged in 24/7. They do not charge 24/7. What you will see is the laptop charge the battery to 100%, run off the charger, and when the battery gets to around 95% due to being unused for a while, it will top it back up to 100%.

The notion that leaving a device plugged in after it's at 100% is bad, is based off the previous NiMH battery tech and people don't understand the difference.

Something else is wrong with your battery. Modern Li-Ion batteries can last for hundreds to a thousand full 0-100% charge cycles before they lose maybe half or 25% of their charge. Where I used to work we had laptops plugged in 24/7 in mobile carts, and after 3-4 years of being plugged in and used daily, they still lasted several hours off a fully charged battery. I did have a few here and there that needed to be swapped out, but you're talking maybe 1 out of 25 that needed to be replaced. This again is just due to non-related battery hardware issues.

Yeah I think we had that discussion a while ago and I remember reading this somewhere else too. I decided to give it a shot again, and the battery is in charge at 0% so something is definitely wrong here. I guess I'll have to buy another one :)
 
Yeah, thats why I'm seeing laptops with windows 8 preinstalled with bad batteries in them with staying plugged in 24/7. SMH, does anybody actually work on laptops besides me??? Evidently not. Come back when you have some real evidence.

You as well, please. ALL evidence shows that there is no danger in keeping Li-Ion batteries plugged in all the time. Yes, batteries die, but it's not because they are left plugged in all the time. Almost always it's because it has been used significantly and has so many charge cycles that it's now dead. If you read my post fully, you'd see that I worked at a school with several hundred laptops, all of which are left plugged in 24/7 in mobile carts. 3, 4, and 5 years into their life cycle and 95% of them are on the original batteries with no adverse effects. While it is recommended to use your battery periodically once every couple months to discharge it, not doing so isn't going to have any adverse effects.

The question is asked, “Should I disconnect my laptop from the power grid when not in use?” Under normal circumstances this should not be necessary because charging stops when the Li-ion battery is full. A topping charge is only applied when the battery voltage drops to a certain level. Most users do not remove the AC power, and this practice is safe.

Technology moves quickly, you aren't alone, lots of people still think batteries need to be discharged fully, not to shallow charge them, and to unplug them once they get to 100%. This is simply not true with Li-Ion batteries.
 
Thats also why this preinstalled windows 8 laptop had a bad battery and also bought a new battery and it wouldn't charge. So something happened to charging circuit on the motherboard, and its not the charging port as without the battery attached the power adapter runs the laptop. So in my experience and years of working on laptops its always best to NOT keep them plugged in.

So I provide you a reference to a reputable source, and you ignore it saying that dealing with laptops over the years, you are an expert on battery technology? Your issue here with a Windows 8 laptop not charging even after replacing the battery, shows that it has nothing to do with keeping a laptop plugged in causing battery problems. What evidence, other than speculation, do you have showing that leaving that laptop plugged in somehow damaged the charging circuitry? I also like how you conveniently ignore proof of hundreds and thousands of other laptops that have had zero problems staying plugged in all the time. Batteries can be faulty, they can be dead or poor performing even when brand new.

What do you propose is a better solution? Run off the battery, then plug in, then run off the battery again, and repeat? That's not practical at all for your average user who likely uses it on a desk for several days then grabs it when they need to run to a meeting for instance. Most new laptops have integrated batteries as well, so you don't have the option to remove them.

What about docks? :p

This. I would love to hear what John's solution is for business users who often use a dock (such as myself right now). My Dell has an integrated battery. Should I run it off the battery from 8AM until noon until it's near zero, then plug it in? I just hope I don't have a meeting to get to when it's nearly empty...
 
My 2 cents on this.
if you have a laptop with a battery on it all the time and you do not use it,the best option to have a healthy battery to last you longer time, is to remove it full charged and store it in a cool place and every 6 months recharge it,and again if you do not use it much like me,i may use it every 6 months.

It says that leaving the battery empty for a while is one of the things that damages it...

I ordered this replacement:

It does, you don't want to store batteries discharged. Taking a fully charged battery and putting it away for a while will cause it to eventually fully discharge, and is not good for the battery.

Also you guys should reed this from PC world;

That article is also 5 years old. The whole debate here was if leaving the battery plugged in would kill the battery, which isn't true (read the paper I linked to above dated April 2016). Taking the battery out is not a possibility in the majority of laptops these days as they are mostly integrated, so that is irrelevant for most.

You assume that majority of PC's here are all new bleeding edge?

The original date on that article is back in 2010 according to the date the comments are, so basically its 6 years old and I'm still calling BS as I've seen way too many laptops batteries or motherboards crap out due to being plugged in all the time. I bought a brand new battery for my GF's laptop a few years ago to replace the original battery. Ended up letting her brother and sister in law borrow for it a few months and they kept it plugged in all the time. Got it back and the battery only lasts 30 minutes before it needs charged again.

Geoff, you can post all the articles in the world that says its okay to keep it plugged 24/7 but from personal experience and proof that I see with my own eyes, it's not good to keep batteries plugged in 24/7. I'm not gonna argue with you about this so don't even go there. All your doing is posting articles, I have actual proof otherwise.

No, but most new laptops in the last year are, so it's becoming less and less of a potential solution for people.

It has been updated since then with new information and statistics, last updated last month.

How many laptops have you dealt with? You keep posting examples from what seems like a handful of laptops that you've dealt with. Again, I will use my past experience from working on Apple laptops for the past 7 years, where only a select few have died after 3-5 years of being plugged in 24/7, many of which Apple replaced as they found those batteries to be faulty.

I'm not saying keeping it plugged in is better than taking the battery out. But, keeping it plugged in is better than charging it, running it down, recharging, and so on when you are at your desk. I am also saying that you aren't going to cause problems if you don't unplug it.
