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.)

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.

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've been troubleshooting slightly higher than expected power usage on my P70. Yesterday, the Lenovo Settings app Battery Charge Threshold displayed a slider that I could adjust.To-day, it does not. There was both a "Runtime Application Reconfiguration" for the Lenovo Power Manager to-day and Lenovo System Interface Driver install/reconfiguration mentioned in the Reliability Monitor. I'm looking at a battery that's sitting at 75% (not charging)- when it should be charging to 80%.Any ideas? I'd like to have a charging threshold.

Hi there, I just got my new Thinkpad X1 Tablet (gen3) and got some problem when using Battery Charge Threshold in the Lenovo Vantage app. I have set the Threshold to stop charging at 80% and start charging again at 75%. It works at first, for a few days I guess, and suddenly during the lunch time today, I locked the X1 Tablet (battery level 78%), going out for lunch, then I come back and the battery level is 100%. I then opened the Lenovo Vantage app to check, and Battery Charge Threshold is disabled. I have no idea completely, why this settings was messed up, I didn't open the Lenovo Vantage app and the setting was cleared. Can anyone help?

Hi I just updated battery firmware for my lovely Yoga C930. This updating made my battery could be charged to 100%.

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!  

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.

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?

The pen that is normally docked and charging in the computer hasn't been functioning since yesterday. I believe it is a charging issue because I saw the battery dying the other day even though I had it in the computer for most of the day. I also noticed something about the charging pins in the pen dock. See the attached photo. It looks like either 1) one of the charging pins has fallen out or 2) one of the charging pins is pulled out and jutting into the hole where the pen goes. Would someone with an active and working lenovo yoga c930 please confirm that the attached photo of the pin connectors in the pen charging port are abnormal? If I can confirm that, then that would help me confirm that this is a problem with the charging port and not the pen itself! Thanks!

Hello brain trust. - I purchased a Yoga c930 for my daughter to use at college and I noticed that after shutting down (using windoes shut down, not sleep mode), the battery will deplete down to around 25% after sitting totally off for just 4 days. I've tested this a couple of times and it's consistent. In addition, it will then fully charge after around 45 minutes on the charger, even though the charge icon in the systray says it will take around double that time I've not used it enough to check the battery life in use, but since my Dell laptop will fire up after going weeks and weeks without a charge, there seems to be something wrong with this machine if it's depleting the battery like that while totally shut down. Any suggestions on what to check or how to diagnose why this is happening?  Thanks in advance

After my friend's laptop wouldn't run on battery power OR charge the battery I tried many "fixes."
 
Shockingly none worked that I found.
 
Only one thing worked for me to my surprise.
 
A last ditch effort was to open up the laptop (sony pcg-81114L) and disconnect the cmos battery for a few minutes to reset the CMOS.
 
To my surprise, when powered on, the battery instantly showed it was charging AND when removing the power plug the battery POWERS the laptop now! (and I'd thought I was wasting my time.)
 
Worked with an off brand battery also.
 
Many times this has saved many computers that have odd "unsolvable" things wrong with them.
 
Surely someone else has done this also but I haven't seen it posted anywhere to my knowledge.
 
Thank GOD for bringing the idea to remembrance!

Hi,  As it is not good for the durability of a lithium battery to be charged above 80% , and unplugging the power once the laptop reaches 80% charge is not really an option: I am wondering if it is at all possible to set the battery charging threshold/limit/maximum to 80% for an HP Laptop ? (For example by using any software or sepcial setting) So basically a tool that stops the laptop from charging the moment in reaches 80%, in order to increase the battery's durability. Other manufacturers (Samsung/Sony/Lenovo...) offer certain battery control tools in order to maximize the lifespan of the laptops battery. Is there a tool by HP/for HP laptops?  I am sorry if this is a repost or if this question was already answered elsewhere. I use a HP Spectre x360 and Windows 10. Thanks in advance!

Hey guys, my IdeaPad U41 shipped with Windows 8.1. My work, however, requires me to use linux as my operating system. I got to choose which distro I wanted to use though, so I went with openSUSE. The problem is, that I can't figure out how to set or unset the battery charging threshold. It is currently set to stop charging at around 60% to preserve battery life. Since I'm going on a trip tomorrow, I need this limit out of the way as fast as possible. Does anyone know of an easy way to achieve this in openSUSE (tumbleweed)? I know that some Lenovo machines ship with linux by default, so I figured there ought to be a way of doing this... EDIT:So, I spent some more time, googling the issue, and foud this tpacpi-bat-tool. It is targeted at ThinkPads and I wondered if it would work on an IdeaPad as well.

Hi everyone!After a month of using Ubuntu on my Yoga 2 Pro machine i realized that the battery is degrading when the laptop is continiously connected to AC.Dual boot with Windows is not an option - because to change the battery threshold you have to make a reboot and keep the space for windows on your ssd drive.So what have i done - i studied Super I/O registers values while enabling/disabling different Yoga 2 Pro management features like battery threshold, quick charge and usb charging and wrote a simple program which allows you to change this feautres from Linux. Find the project here:https://gitlab.com/mikoff/Y2P-PM/The program can set up different Yoga 2 Pro power management features and read their status. It was tested on my machine under Ubuntu 15.10. Please note that you have to be root to run the program.
