XPS 9560 disable recharging?

Hey,
so I have received my Dell XPS 9560 and played around with it a bit.
Given the laptop will be connected to AC mostly, I wish to preserve the battery efficiency best possible.
I am aware that once the battery reaches 100% it stops the charging and starts transferring the power from the power plug directly to the motherboard. Although I do notice that the next day it might of gone down to 99%, then the laptop will charge it back up to 100%.
Firstly, in regards to keeping the longevity of your lithium battery I can understand, is among things to keep it charged around 50%, and never let it go below 20-30%.
Secondly, apart from warm temperatures, recharge cycles is one of the main contributions to shortening the battery life, so with that being said, if I know I will be having the AC plugged to the laptop most of the time, I'd recon it would benefit me, if I would be able to charge the battery to around 50%, then have the laptop pull power directly from the AC to the motherboard, until the battery by it self falls below 30%.

It would be great if there would be a way for me to have a switch that lets me decide manually when I want the battery to be recharged.

What are you guys opinion on the matter, and Is this possible? The last resort is to pull out the battery and store it in the fridge, or just keep the battery inside and suck it up, then order an additional battery in 1-2 years time, once the current battery isn't so efficient anymore.

 

You can do this, you can either use Dell's power control app or you can set charge thresholds in the bios.. I've got mine set to stop at 95% and to not charge until 50%..

 

Hi Unferth33,
I found the setting in the Dell command power manager-->Battery Information-->Settings-->Custom, here you can set this.

Although it won't let you set when to start charging, to anything below 50%
So I guess I will set it to begin charge once battery hits 50% and stop at 60%.

Thank you very much for pointing me in the right direction.

 

Go into BIOS and do it from there. You can set any thresholds you want, including below 50% minimum charge.

During the boot process, hit F2 to enter BIOS setup. Then go to
Power Management --> Primary Battery Charge Config.

Select Custom.
Below that, enter the battery charge percentages you want. I'd recommend between 40%-60% or anywhere in that range.

When you know you will need a fully charged battery, come back into BIOS and change the setting to Standard. It will behave like a "typical" charge profile, and just charge your battery to 100%.

Avoid the Adaptive Charge setting. It's pretty useless.

Hi Kent,
thank you for the tip, I tried your recommended steps, unfortunate when trying to set the threshold below 50%, the setting via bios still tells me that this is not possible.

 

Set it to adaptive and leave it alone, it will last you just fine

 

there is literally no reason to set it below 50%. You get nearly no returns for reducing the charge below 75%. Even at 90% it will still only lose a couple of % a year (at room temperature)

 

Have tried to ask on another thread, no one answered.

Have almost the same question / problem. Use hardly my current Asus on battery. It has battery externally, so easy to remove, it works fine without battery. So was my question, “will the computer still work if you disconnect the battery connector to the motherboard? (If used more as a desktop PC)?”

Can understand on answers you get that in BIOS one can interrupt / off charging you must then just be sure that it never takes power from the battery even if connected two AC.

 

Is the premium warranty extension available on battery ?

 

Just learned about 2 weeks ago that the battery warranty is 1 year, regardless of the warranty level.
But, if you talk to their support you might get approval for the replacement.

 

For the current XPS range?
I understand removable batteries are 1 year regardless but as this is a non removable battery it should last for the laptop warranty as it isn't considered a user replaceable part. Including extended warranties.

 

That's what I was told by Dell technician as well as Dell support when I found that the battery of my old 9530 gone bad.
It was actually swollen to the point that my touchpad was sticking out and got almost non responsive.

So I called premium support and that what they told me... so they transferred my case to some "Resolution Center" for approval and I got the new battery.

 

I can see us all having to go through the resolutions team, but throw your weight enough and you get your own way!
I can not find any mention that an extended warranty doesn't cover the battery, anyone else?
