X201s Battery Charging Didn't Stop Automatically

Assalamualaikum and hello,
I notice that there is a battery maintenance support for the battery charging which it will automatically starts the charging once the battery reach the minimum limit and stops at the maximum as we set.But I've tested a few times before with this applications and found out that my battery doesn't stop charging at 90% as I set,instead it keeps charging until 100%..(hopefully the battery doesn't overcharge)..
So,i'm wondering whether this applications is actually working or not(or maybe I need to update some drivers perhaps)..Coz I thought I might leave the laptop's charging and automatically stops once it's full or reach the maximum settings meanwhile I could do another work..Someone please help me..
Solved!

Hello Pidot~!
Try updating the BIOS, Power Manager, Power Management driver and see if it stops charging at 90%.
If it doesn't stop charging despite the threshold being set then try doing a battery gauge reset and see if that helps.

I have a Y2P (i5) ... Feel free to ping me if you want me to test some applications with your Y2P if you have the same model. I don't mind keep doing recovery on it if needed .... =)

Battery recalibration: didn't stop, simply shut down

i planned to calibrate my Macbook Pro battery, so yesterday night i let the battery get very low (after having recharged it completely), the battery level alert appeared, and after some minutes the MBP shut down.
it didn't stop, it actually shut down: no white led in the right corner, nor the computer restarted from where i leaved my work when today i turned it on again. there could be something wrong?
p.s.: i also noticed that clicking on the battery icon there is written "service battery" with a warning icon: what does it mean?

The computer will shut down when the battery gets very low. You can only restart with the power adaptor plugged in. You should then leave the power adaptor plugged in until the battery is fully recharged. When fully recharged (if it will recharge at all open System Profiler and click on power to find out the battery condition.
As your MacBook Pro is a similar age to mine it's possible that you do need a new battery, especially if you regularly run off the battery. System Profiler will give the current full charge data as well as how many cycles the battery has been through. If the battery is not less than 80% and has completed fewer than 300 cycles then Apple considers that you've had fair life from the battery. There was a replacement program for batteries that didn't reach this standard but I think it has been closed as all the suspect batteries are now probably more than 3 yrs old anyway.
Post those SP stats for the battery and we can easily assess whether you have to face the cost of a new battery.

Battery charger does not stop charging when battery is full

On my G4 laptop, the battery continues to charge even after the battery is obviously full charged. Also, the battery life indicator in the menu always says "calculating" rather than giving me the remaining time left on the charge.
I've tried two different batteries, and I've reset the PMU.
Any ideas or help with this problem?
Thanks!

I have the same thing happening to me. My indicator at the top right of my screen shows the plug sign at 99% or 100& but the amber ring doesn't change to green. After a while the symbol changers to charge but the ring remains amber no matter what the symbol indicates. I've also reset the PMU. Waht worries me is that something is wrong. Should I ignore the improper amber ring color?

X201 Battery Suddenly Stopped Charging

I'm a new user of the X201. I was sold on the 'name' and 'reliability' and 'quality' of the product, the X201, on the design and size and power. So I paid the premium for this notebook, where I could have easily bought TWO Acers with similar power and storage etc.
This was in June 2010..
The battery suddenly stopped charging and status was 'amber' and software says battery is charging... it's not.
battery condition is all green... good...
what's happening?

I am experiencing the same issue with my X201i. It is just weeks old and battery has been used for five cycles.
Unfortunately it seem to not want to charge the battery anymore, and it stays as 0%. I have been in touch with Lenovo, and they are shipping a new battery that I will try. However, I tried to upgrade form bios 1.14 to latest, but this did also failed because of no charged battery which is required for a upgrade :-(
Any more updates on this so I can try to get the battery charging again?

Any way to stop battery charging at under 100%?

Research has shown that a battery kept at 40% charge will retain 96% of capacity after 1 year (at 25 degrees C), while a battery kept at 100% charge will retain only 80% of capacity after the same period of time.
Is there any way to control the maximum charge level, so that the battery stops charging after a certain point (say, 40%, or 75%). Thanks.

Do you have a link for the article you read that has this info? I'd love to read it!
Like the above poster said, you can't control how long the battery charges--unless you unplug the cord yourself.
I would like to mention something for you. My battery is 11 months old, and has maintained 98% of its original capacity. Within the next 4 weeks, it will hit the one-year mark, and I don't anticipate it failing on me before it has reached the typical lifespan of ~300 charge cycles. I wouldn't be surprised if it hangs on for another 100! It currently has 264 to its credit. I think my battery is doing pretty well--and I run off it for a few hours nearly ever day
Of course that's an expected outcome with most lithium rechargeable batteries. However - they do have their drawbacks including an inherent loss of total capacity from the aging process.
The best thing for your battery is to USE it, even if you're sitting at your desk much of the time. Unhook the power charger for 30 minutes, or an hour, then reattach it. If it doesn't seem to be working properly, calibrate it.
It all depends. Using a battery and charging it to near maximum by definition cut capacity because of some loss of the electrolyte solvent when it gets vented. In NiMH batteries, the solvent is water. It's a non-water solvent for lithium rechargeables. If it's not vented, it could potentially explode. Using a battery every day will result in noticeable loss of capacity. There's a balance to overuse and underuse of a lithium rechargeable battery. Apple recommends that a battery be partially drained at least once a month. My MacBook is set up with an iCal reminder to use battery power once a month.
The 40% you mentioned from the article is something I've heard before, but I believe it was mentioned in relation to storing your computer for an extended period of time(ie several weeks). If you wanted your battery to be healthy when you returned, you wanted to store it after you'd partially discharged the battery.
I've brought up the extreme case of first generation hybrid car batteries. They employ a different strategy for charging that takes advantage of an always present charging source (the internal combustion engine and generator). They take advantage of the extreme case where the battery is intentionally kept between 40-65% of charge nearly all of the time. Going a little bit under or over this isn't a big deal. This keeps it from the extremes of near max charge and near min charge; both tend to reduce battery capacity for different reasons. The electrical output is only a supplementary power source used during peak demand periods. I've heard of some original batteries from Toyota Prius taxis that have survived 400K miles of service; that probably meant 100,000-200,000 of the shallow charge-discharge cycles. The fact that only a small range is needed means that they can continue this use for a long time. It probably would have been noticeably degraded after maybe 1000-2000 20-100% deep discharge cycles. The total amount of energy drawn over the lifespan is many times with the small discharges compared to deep discharges. You're typically using 25% of the charge hundreds of thousands of times rather than 80% of the charge a few thousand times.

Stop battery charging with plugged MacBook Pro

Hi,
is it possible to stop battery charging on a MacBook (Pro) with the power plug connected? I have looked into the PM api docs but cannot find anything to do that.
The idea is to make a menu app to toggle between "Preserve Battery Life" and "Full Power" modes. According to http://www.batteryuniversity.com/parttwo-34.htm, Li-Ion batteries loose less capacity over time when charge level is about 40% of max. capacity, escpecially with the comparatively higher temperatures that are given in a running notebook.
So the "Preserve Battery Life" mode would charge to say 50%, then let the MB run on battery to about 30%, then charge again etc. Before taking it on the road, one would switch to "Full Power" mode to charge the battery to 100%.
Thanks,
Bastian

My ipad will not power on after update. I have tried connecting to computer which doesn't recognize it. I have pushed top and circle buttons at same time. It had a battery charge before it died. I tried to stop the upload and am afraid it 'crashed'

My first genteration ipad will not power on after update. I have tried connecting to the authorized computer which won't recognize it - does not acknowledge a device is plugged in. I have pushed top and circle buttons at same time. It had a battery charge before it died. I tried to stop the upload midway and am afraid it 'crashed'

Try putting it into recovery mode.
Connect iPad to your computer via USB while it's turned on.
Open iTunes
Hold the iPad's Sleep/Wake switch (power button on the top of the iPad) down until the "power off" slider appears.
Power off the iPad completely (wait for the progress spinner to disappear).
Hold the Sleep/Wake switch AND the Home button down for a full 10 seconds.
After 10 seconds (the second time you'll see the Apple logo on the screen) release the Sleep/Wake switch while still holding the Home button.
Continue to hold the Home button for another 10 seconds until the USB connection image appears on the iPad's screen, then release the Home button.
A pop-up message will appear on iTunes saying it has detected an iPad in recovery mode, you must restore...
Click on the "Restore" button and the process will begin.

Ideapad S400 battery charge until 60% and stop charging, on Linux

Got the same issue that windows users had but, I can solve the same way cuz I did Install Linux on my s400, is there anything that can do under linux?

Hi Yasumitsu,
Welcome to Lenovo Community Forums!
I’m sorry to hear that your S400 Laptop is charging only upto 60%, this issue in windows will get resolved by install the LEM (Lenovo Energy Management) and by choosing the (Optimized Battery Health), the Battery charges only to 60% and stops charging the battery and then it take its power from the charger, so if you want to charge the battery to 100%, you need to choose (Maximum Battery Life).
Do post us back if the issue still persists.
Best Regards
Shiva Kumar

Does the battery charging in the macbook pro retina automatically cut off when the battery is fully charged?

Does the battery charging in the macbook pro retina automatically cut off when the battery is fully charged? or does it continue charging?In which case,is it better for the battery life to switch off the power supply or leave it on while using the macbook?

Yes, and the pilot light on the MagSafe2 connector changes from orange to green. If you unplug, you will start draining the battery again, whereas if plugged the Mac will take power from the brick and leave the battery in a charged state.

Battery charges for 20 seconds , then stops. Lenovo yoga 3

My battery started having sudden drains when in sleep mode. As soon as i woke it up it showed 0% left and shut down. I installed all the updates. The problem seemed solved for one day. Then it drained again but this time did not shut down. It kept going and when plugged in shows 'plugged, not charging' so i started the calibration. That was yesterday. This morning it is still running. I so do not want to send it back, but if there is no way to fix this I may have to
Moderator note: Post edited.Messages moved to this thread from https://forums.lenovo.com/t5/Lenovo-Edge-Yoga-Flex-Laptops/Battery-charges-for-20-seconds-then-stops...

I broke off the calibration since it seemed to be doing nothing at all, then let the computer fully drain.On stertup everything seemed fine for a bit till it then again failed to recognise the battry being charged. I gave up,and plugged in laid it aside. After a few hours opened it up again and presto, battery regognised, fully charged and now after a night in sleep mode 98% left and still functioning...

Recommended First Battery Charge

Hi everyone. Im receiving my 8Gb iphone tomorrow and I was wondering how long should I leave it charging for the first time? Ive seen many of you having problems with battery life and Ive looked everywhere but Apple doesnt state anything.
With all my previous phones, as soon as I bought them either on the manual or the service provider's salesperson would specify how long the first charge would be. Its something about charging it a long long time so it's programmed to full capacity, cause if the first time you charge it for just a little while or the typical 2 hours, the battery wont use its whole capacity. Such as with laptops. May be a myth for all I know but its worked with my laptops and my cell phones so far.
So does anyone have an idea of how long should I charge the phone for th efirst time?
Id really appreciate it. Thanks! Susana

You can only charge the iPhone's battery or any battery until it is completely charged. The battery's charge can't go past full - the charging process will stop when full.
Some people like to "season" their battery which I don't think makes much if any difference but to do this, make sure the battery is completely charged.
Use it until the iPhone shuts down automatically - which it will do when the battery is depleted.
Charge it completely - don't disconnect it until completely charged.

T520: Slice battery charging thresholds stuck

I bought a T520 (4240) a few months ago and, like most people around here had the same issues with pulsing fans and, on applying BIOS 1.28, CPU throttling issues. I'm not sure if the latter one is fixed properly yet, but I also have a problem with the battery charging thresholds that has me stumped.
I have the 55++ and 27++ 9-cell main and "slice" batteries. For a while I let them charge up to 100% whenever connected to AC, but then I read that a 100% charge level is not recommended for day-to-day operation.
I use Fedora 15 Linux 99.9% of the time on my T520. I wanted to set the battery charge thresholds to avoid the 100% charge level, but the "tp_smapi" Linux driver doesn't work for the T520 (yet). I read somewhere that if I were to set the charge thresholds with the Lenovo Power Manager in Windows 7, that they would work in Linux as long as the laptop was not completely powered down when switching from Windows to Linux (i.e., use a warm boot). Well, it worked. In fact it worked really well: I could even power down and remove the batteries and something, somewhere would still remember that I wanted to start charging the slice battery when it dropped below 35% and stop charging it at 80%, even when running Fedora 15.
Having used the machine for a few weeks, I found that I used it on battery power a lot and liked to "top up" the batteries over night. The 35/80 thresholds didn't really suit my working pattern. So, back in the Power Manageer in Windows, I changed the battery thresholds from 35/80 to 50/88 for both batteries (55++ and 27++). On booting back to Linux, I noted that the main battery would respect the new levels, but he slice battery was still stuck on 35/80. Back in Windows, I tried changing the levels in different ways, but the slice battery refused to charge to more than 80%, even under Windows, no matter what I did. It seems that my first change from the default (is it 96/100?) to 35/80 has gotten stuck somewhere and I cannot change it again.
I even notice in the Power Manager that the slice battery constantly toggles between charging and not charging when under AC power if I set the threshold to 85/90. Because the 80% level where the battery is stuck is lower than 85% (my new "start" threshold), charging kicks in, but it immediately stops again, as it won't go over 80%, then, of course, it starts again and stops again, and so on.
How do I fully reset the charge thresholds on the slice battery so I can exceed 80% charge?

I had kind of given up on this, but thank you KooMaster for your confirmation that I am not alone with this issue. I don't think this is a problem with the Lenovo or Windows software, as this happens to me when running Linux without either of those. My guess is that the problem is in the embedded controller (EC) firmware. It is responsible for charging the batteries and enforcing the charging thresholds (that's why they still work even when the machine is turned off).
It probably makes sense to charge each battery to 80% first, as it likely only takes half of the overall charge time to get to that level (the last 20% taking as long again). That way, we get both batteries to a useful charge level as fast as possible. However, based on your observations, it seems that someone in Lenovo forgot to tell the EC to check that the main battery has reached its upper charge threshold, not that it has reached 100%, before topping the slice battery up to its upper charging threshold.
Can someone in Lenovo please comment on this issue, as I raised it over seven months ago now and I haven't heard a single word from any of you about it? "KooMaster" has confirmed the problem on a different model with different batteries, so it seems highly likely that a quick check of the (shared?) EC firmware code and a patch will resolve this quite quickly.
(I updated my BIOS and EC firmware today and it made no difference to my problem.)

Weird battery charging behaviour

Ok, I'll start by saying that this is a problem that has been coming and going for quite a while (definitely months, maybe years). But for the sake of illustration, I'll describe what happened today.
So last night I was using my laptop on the couch (not plugged in) and fell asleep. Woke up to a dead battery. No problem, I plugged it in and woke it up and was good to go. Several hours later I noticed that my battery charge was still at 1 or 2%, though clearly it was running just fine off AC power. Looking at the light on the power adapter, I thought it was completely off until I read a few support posts and found out that "dim green" is an option. Upon close examination, yep, dim green. System Information said the battery itself was ok (cycle count 153, condition normal) but not charging. Under AC Charger Information, it said Connected: yes, Charging: no.
Unplugging and replugging the adapter a few times didn't seem to do anything. There's no obvious gunk in around the terminals. I shut down and reset SMC, no change. Finally I just fiddled with the adaptor (unplug, replug, flip around, wiggle up and down) until the light turned briefly green, and then orange. Now it's clearly charging (up to 38% now, and battery icon has a little lightning bolt) although System Info still says it isn't charging.
Oh, hang on. I just quit and restarted System Info, and now it says it is charging! Huh.
Addendum: While adding tags I noticed that the light on the adapter is back to dim green. System info still says it's charging, and battery % charged numbers are still going up.
I'm guessing it's an issue with the magsafe adaptor, just not sure how you end up with a temporary situation where the laptop can run on AC power but can't charge the battery.
Oh, and in case it's relevant: I'm running a 13" mid-to-late 2009 MacBook Pro, the kind with a non-removable battery, though I did have the battery replaced (by a friend who is Apple-certified) less than a year ago. The AC adaptor I'm using is the one that came with the computer. I'm pretty sure the problem pre-dates the new battery (since it comes and goes, and because I spend a lot of time using the laptop at home while plugged in, I don't always notice).

I had this exact same problem with my mid-2009 MBP as well. My adapter (white connector) has suddenly stopped charging the computer and displayed a very dim-green LED instead of the normal orange or bright green.
I came to the conclusion that the adapter has been shorted out in some way (possibly due to old age) and that was the cause of this. Sure enough my local Apple retailer sold me a new adapter that everything has been fine ever since. I even enjoy the new design - the metal-tipped connector that faces sideways.
Unfortunately the adapter cost me $80, but was a small price to pay as opposed to replacing my laptop. Since this sounds like the exact same issue I faced, I would recommend you purchase a new MagSafe. Just make sure you get the right one for your model (should be a 60W MagSafe)
Hope this helps you out!
