How to do a full charge when "charge threshold" mode is activated

Q: How to do a full charge when "charge threshold" mode is activated

Hi,I just activated battery "charge threshold" mode (with the default 80-85%). Let's say I need to charge the battery to 100% once a week, how do I do that without changing the threshold in Vantage? Thank you!

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

A: How to do a full charge when "charge threshold" mode is activated

You can turn off chargin threshold. It should fully charge. Then turn back on charging threshold afterwards. I've done that on Thinkpads before. Turn off charging threshold and once charged to 100% for a out of office business appointment then turn back on charging threshold. A little error message pops up in vantage that something to the effect charging threshold wont take effect until battery level is below threshold limit. The thresholds are still stored from when you turn charging threshold off and back on in Vantage.

Not sure where I'd submit a bug report, has anyone else experienced the following? I have my charging thresholds set to 80% in Lenovo Companion for my T470. However, it seem like half the time it will end up charging one or both batteries to 100%. What seems to happen is it charges to 80%, and it might sit there for a little while, and then a battery creeps to 81%, at which point it then gets charged to 100%. I'm assuming the code behind the threshold portion of the program is saying if charge == threshold rather than if charge >= threshold to determine when to cut the charging off.

My P51 battery is set to start charging when below 80% and stop charging at 95%.  (Lenovo Companion> Hardware Settings> Power> Battery Charge Threshold> Start Charging When Below 80%> Stop Charging at 95%).  I have my P51 plugged in all the time.  The battery always stays at 95% charged, it never reduces down to below 80% and then automatically recharges back up to 95%.  Obviously the P51 will run the battery down when unplugged and then when plugged back in it will recharge back up to 95% capacity and stay there.My older T530 had the same settings as my new P51 does but it honors the charging perameters  set by the T530's Lenovo Companion's Charging Threshold....The battery charge gradually reduces to below 80% and then it automatically recharges back up to 95%...Thus "exercising the battery".                       My question is two fold...1.  Why doesn't the P51 perform the same way that the T530 does using the same Charging Thresholds?2.  Isn't it beneficial for a Lithium Battery to vary it's charge vs. staying charged always at the same level? Curious...Altoid666

A:P51 Battery Charge Threshold

My guess is that the power management works the same.  Probably, the T530's cells are slowly losing charge over time and when it gets below 80% it charges.  The new battery cells probably lose charge also, but MUCH more slowly.  When it gets below 80%, it will charge.  If you want to vary the charge level, unplug it for a few minutes, occasionally.  I think Lithium cells degrade over time, but I think the degredation speed has more to do with ambient temperature and number of recharge cycles.

I am driven crazy by Battery Charge settings on T440 (Windows 10). It charges internal and external battery to 80% whatever I do. I can't change this (for example to increase level so as to maximise battery life when going on a trip). The controls in Lenovo Settings have no effect - ON/OFF, changing thresholds all do nothing. I have looked in the Registry and changed the Start and Stop Values for the specific batteries and also disabled both Start and Stop charge control - this has no effect after a system Reset although the new Registry settings are there. The same 80% battery thresholds are used when the device is switched off which must surely mean that it is not software controlled and some settings must have been passed to to the battery or charging system hardware. As far as I know I have the latest versions of Lenovo Settings, Power Manager etc. The fact that the registry settings are ignored leaves me nothing else to try. Any ideas?

It's great that Lenovo Vantage cares about the lifespan of our batteries and offers us a choice of charge threshold.  But it offers no guidance what maximum level to set, except that it should be less than 100%.  Lenovo must have studied the effect of maximum charge on battery lifespan, and I wish it would share that information with us.  Higher maximum offers a convenience for most users, but they might be willing to trade some of that convenience for some increase in battery lifespan.  We need data in order to decide.  For example, does even setting the maximum at 95% have significant livespan advantage vs. setting maximum at 100%?  Without knowing such things we're just bumbling in setting battery charge threshold.

Hi! I have X1C 5th 20HR. I was using it with the Windows 10 Pro which came built in. I was using it with the battery charge threshold option (95%).After that, I switched to Ubuntu and clean installed it. I tried to change it (charge threshold) also with Ubuntu, but I failed. The battery was only charging up to 94 % all the time. I was okay with it.Yet, after several months, I had to change back to Windows. Now I have Win10 Pro again, but this time, whenever I try to set up a threshold, it is set for several seconds, and after that, it turns itself off automatically. I tried it like 30 times already with a different threshold, with different levels of battery charge, almost with an empty battery, but no result.Is this behavior expected? How can I fix it? I will attach my attempt as GIF file

I have a Lenovo T460s that will only charge when the computer is either turned off or in hibernation. When turned on, I get the dialog box stating that "Incorrect AC adapter is attached." , along with the boilerplate text that details the problem, and gives some helpful advice.  I have searched the forums for a solution, and have tried a few things (like disabling airplane charging mode) but to no avail. We had replaced the power cord and charger, but the problem persists. I suspect that the charging port itself was damaged, and not the charger. Is it possible to determine if the problem is truly due to a lack of amperage (or wattage)?  I suspect that the rectangular charge adapter has a simple detection mechanism to determine the wattage of the power supply, and that this mechanism is causing the laptop to incorrectly detect the wrong type of power supply.If this is the case, is there a setting, either in BIOS or in Windows itself, that can disable this detection and enable the laptop to charge, despite the damaged port? (I realize this is not ideal or recommended.) Thanks in advance.

Greetings,

After a while of searching with no useful result, I decided to come here and ask for help. Do any of you know of a program that creates a visual alarm when your battery is fully charged and doesn't stop until you press a button? Both visual and audio alarm at the same time would be awesome but I just need to see when my battery's fully charged so I can unplug.

I've tried several sound alarms before but I always miss them because I have either headphones or earphones plugged in and hung on the side so I wouldn't be able to hear it.

Dear Sir  Welcome to Lenovo Community first of all lets do small troubleshooting steps, if its working ok if no so you have to deliver your device to the Service center to replace the battery if it still under warranty. ( find the list of service center link at the end of the message )if you do not have the power manager or power management you can download it from the below link:http://support.lenovo.com/eg/en/products/Laptops-and-netbooks/Lenovo-Y-Series-laptops/Y40-80/downloa...after installing you have an option inside called battery gauge reset, you have to make it night when u do not use the laptop cause this operation will take more than 6 hours to full charge the battery then difull charge then full charge again to refresh your battery, after you do that try your machine, if the battery still drains fast so you can visit the nearest service center to your place. https://support.lenovo.com/eg/en/contactus/supportphonelist Best Of Luck

Hi so I'm kind of paranoid about maintaining my battery life so every now and then I check whether the remaining capacity is the same as the full charge capacity in HP Battery Check. When I checked this maybe 6 hours or so ago, Full charge capacity is 5344 mAh and remaining capacity is 5309 mAh. Then when I checked it now remaining capacity lowered to 5181 mAh. Is there a problem? P.S. I keep this laptop plugged in all the time because I play games on it and sessions usually last from 6-12 hours every day. I only unplug the laptop when I'm going to school (I seldomly bring this to school) and after I shut down my laptop. An HP expert said that I can just keep the laptop plugged in even after charging it to 100% since there is a technology in place when the laptop hits 100%, it uses the electricity from the charger and not the battery.

It's possible you got a bad one. It's also possible the computer, being brand new, is doing a lot of things that eat battery. FWIW, I've noticed the battery gauges are rarely accurate out of the box. They give a best-guess depending on what the computer's doing over a particular slice of time. If your machine is downloading and installing windows updates, doing a virus scan, updating other programs and what-have-you - like all new computers do - then that coupled with a gauge that hasn't learned the computer, yet, could lead to the indications you're getting.
 
Give it a couple of full charge-discharge cycles. Let everything update. Update your BIOS and drivers, as well. If your machine came with McAfee, temporarily disable it.  THEN see what kind of life you get. If it's still short, use Task Manager to see if anything else is running in the background. If not, then it's possible you got a bad battery.
