How to stop M14x battery from charging

Is there a way to stop the m14x battery from charging at a certain point? For example stopping the charging at 40% and only using the AC power. Removing the battery seems very difficult so is there some kind of software that can do this?
I feel like this is question thats been answered before but I can't find any previous threads.

 

There was a discussion about disabling charging all together, and that option is in the BIOS.

Not sure if there is software that will monitor and manage battery charging.

 

Doesn't it stop charging at 100%?

 

yes but if your using it more as a desktop replacement the battery will drain slowly over time and then it will constantly be at a discharge/charge state causing the battery to become consumed faster...

 

actually does it help? cause i've had the a fujitsu lifebook for 4 years and i plug it on at least 8 hours a day and never take the battery off.. it's a working laptop so it's on 5 days a week for 4 years.. and i still get 2 hours battery life out of it... compare to when it's new.. 2 and a half hours maybe 3.. i always tot taking the battery out isn't helpful.. but i'm not sure..

 

this is ment for if you keep it plugged in all day and night for months at a time.

you are still using it in a portable sence.... so its not really beneficial to you

 

I agree with ted264. If you rarely use it off the desk, keeping it plugged in at a constant charge/discharge state, I think you can harm future battery life. If this was the case, you can disable battery charging via BIOS.

If I understand correctly, the safest is to have the battery charged at 40%, then disable charging. If you use it as a true laptop though, using it on battery power often, no need to worry I guess.

Anybody feel free to correct!

 

Yea the problem is that for about 2 months I'm not going to be taking the laptop anywhere. I'm just using it on the desk so I don't want the battery to be at 100% continuously. Like somebody said earlier, I believe the battery can be preserved best when it is at 40%.

So just go to the BIOS at startup and the settings should be there?

Thanks

 

Yes the setting is definitely there. If you don't see it at first, it may be under the advanced options in the second tab.

I don't remember it's specific location, but I know I have seen it

 

Are there any negative consequences to switching the BIOS often from charge battery to not charge the battery besides the hassle?

 

A bit confuse reading the earlier posts, just want to confirm that is it good for the battery life If I use it as a Desktop replacement? Because that is what I going to do with my M14x, since that I dont or will never use it on battery.

In the BIOS is it really an option to have it stop charging once it reach 40%?

 

No, the BIOS won't do that automatically. What you do is drain the battery to 40%, reboot into BIOS and set the option to not charge battery on AC power.

I wouldn't think so....

 

Oldish thread I know.

I've been wondering this too. The lenovo laptops come with software with manages this for you. To optimise the longevity of the battery for when it really is mainly plugged into mains.

It ain't great because you might want to take you laptop off desk all of a sudden and be stuck with 30% charge, because it hasnt drained down enough to start a charge to full.

Alienware really need to get something in this space though.

 

So does Sony, it's why I didn't get a m11xR3 (since I'm a sucker for the m11x line, and have had the other two).

Oh, well, there was a workaround with the hotkey in one of the m11x models, but I don't know what happened with that.
