Lenovo Z580 battery & charging

Hi
I am looking to save a bit by not charging my battery cuz I am using my laptop constantly plugged.
Is there some option that would allow me to not charge the battery till it drops below 10%.
Is removing the battery the only solution?
if I remove my battery and there is suddently a blackout do I lose all what I have been working on or does the laptop save that?
Cuz many times when similar happens and the battery is in I can just turn on and continue from where I left,while without the battery I have to turn on and wait for the laptop to start again.
Also,can you tell me how much this laptop consumes electric energy per hour?(I figure around 40W,but I could be wrong)

hi blackdragonstor,

Genuine Lenovo Replacement Battery Does Not Charge

After reading the number of people on this forum who experienced the same problem I faced (my T61p 9 cell battery went from fine to dead overnight), I took the advice of the contributors and purchased a new, genuine Lenovo replacement battery from a seller on e-bay. I compared the new battery to my original battery and here's the test results for each of the 2 batteries;

After charging the replacement battery overnight, the battery gauge never went above showing 24% charged. I unplugged the AC adapter and it went from 24% to its current level of 5% in about 15 minutes. After plugging the AC adapter back into the computer, the battery will not charge.
Any advice would be greatly appreciated.

It is hard to be sure without seeing it, but best guess is that the battery charging circuitry on the motherboard has died. If you still have remaing warranty, now is the time to use it.

Lenovo Vibe Z2 Pro (K920) battery charging time

Hello everyone,
I wonder, if anyone could help me, please.
I'm experiencing an interesting issue related to battery charging procedure of brand-new Lenovo Vibe Z2 Pro (K920).
The thing is, the first two battery charging procedures took about let say 2 hours 40 minutes both.
But the third battery charging procedure took about 3 hours and 10 minutes exactly!, which I consider to be rather strange, mostly because of web reviews of this smartphone, where 2 hours and 30 minutes typical charging time is described.
I understand the fact that brand-new battery has to be initially "formatted" and it's capacity is therefore gradually increasing after few battery charging attempts.
Needles to say, after that third battery charging procedure, the battery life has been also significantly improved. I use genuine Lenovo charger which comes with the phone in the box. The only thing, which I changed since first two battery charging procedures, was turning ON "Core efficiency" in the Lenovo Battery Manager.
Could it be the reason of such extended battery charging time or is it perfectly normal bacause of gradually improving capacity for brand-new battery? Could it be defective battery? Has anyone of the owners the same experience or what is yours typical battery charging time using in-box charger?
Thanks in advance for any advice, suggestion, explanation.
Martin

Lenovo Z400 Battery will not charge

Hey Lenovo Forum: I'm having a battery charging problem that seems slightly different from any on this forum so far. I just acquired a T430 running Windows 7 (64-bit) like a charm. After a few issues with the audio drivers, everything has been running smoothly. Abruptly, yesterday, when I plugged it into the wall socket (the same socket that it had sucessfully charged on earlier) it failed to charge. Thinking it was the outlet, I tested it. The outlet and adapter are both working fine (the adapter powers the computer no problem with the battery removed from the system). The lock switch on the battery is in the propper position (i've tried both). The battery is not overheated (it's cool to the touch). I tried removing everything and holding the power button (apparently that discharges some built up charge in the system) then reconnecting the battery and AC adapter, nothing. I just downloaded the power manager which (when the laptop is, in fact, running off of AC power (the battery charge indicator hasn't draining in hours of continuous use) reads: i have also tried reinstalling and updating the "Microsoft ACPI - Compliant Control Method Battery" driver in the Device Manager. Nada. In summary, the machine is fully functional when tied to wall power, but the battery won't charge. The only thing I have yet to try is using the Energy Manager to perform a battery gauge reset, which I'll try tonight (but hopes are not high). Am not really looking to replace a battery that's basically brand new and seems to be in otherwise perfect quality. On the off-chance that this is a helpful piece of information, I am using the power adapter to standard wall power in India. Don't think that should be an issue - the computer had no issues charing for a few days here and other devices have no issues. Any thoughts? Thanks!aaron

Hey x220forme, Thanks for your response. Funny, you're right, not sure how that happened in the title. It's a T430. I'm not sure about the battery, I bought the laptop (battery included) from a 3rd party refurbisher. If there's any other info from the battery that would be helpful, please let me know. Cheers,aaron

Lenovo G570 battery not charging. Battery stuck at 90% but has no charge at all.

Hi,
My Lenovo G570 battery is stuck at 90%. It says plugged in, not charging. It just happened over night. Next day battery refuse to work.
In windows it says battery 90% and is not charging but battery has no charge at all. When I disconnet the A/C power laptop just shutdown immediately. As soon as I unplug the power laptop just shutdown as there is no charge in the battery.
I did reinstalled the Power managment and also updated it. I all unpluged reboot in OS, restart, put battery back and boot into the OS back. Nothing seems to work. Is there any suggestions?
UPDATE: I just installed Lenovo Enery Managment in windows 8 before I was trying in windows 7. In the battery tab there are two options
Maximun battery Life
Optimized battery Health
It is selected to "Optimized battery Health" and won't change regardless of power plan. I click on "Maximun battery Life" and when I open the app again it reset it to "Optimized battery Health".
UPDATE # 2: Lenovo Solution Center say that battery life is GOOD. "Your battery is in good condition".
Solved!
Go to Solution.

LSC (lenovo solution center) does "NOT" support the G570 further information at http://support.lenovo.com/en_US/downloads/detail.page?&LegacyDocID=MIGR-73784

Lenovo K 900 --Battery charge indicator always shows 100 %

A strange issue after firmware upgrade in lenovo K 900 , When I charged to 100 % , the phone always shows 100 % charge . It is not getting updated and after using for 6-7 hrs the phone gets switched off without any notice . Now I can charge again and this time the battery charge indicator shows correctly . but again the same issue is seen if the phone is charged to 100 % .

Let it die all the way down, to recalibrate the battery, and then fully recharge. See if that helps.

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...

Yoga 3 Pro Battery Charging Problems

I've combined several discussions into one because there are multiple cross-overs of symptoms.
After reviewing all the posts, I see there are two types of problems discussed:
Battery charging but only to a certain percentage
Battery intermittently charging
Several people have reported success with their limited battery percentage problem by following the solutions suggested by MarinM and Vladtech.
For the intermittent charging, several people have reported that sometimes the battery charges, sometimes it doesn't. I'd like to dig into these reports. I have a few questions I'd like to ask.
When does it charge, when does it not?
Are there any patterns to this?
Does swapping electrical outlets make a difference?
Does the USB 2.0 charging port appear loose?
Does the cable show any signs of damage?
Does the AC adapter show any signs of damage?
When a second device is plugged into the extra USB port on the AC Adapter, does this impact Y3P charging?
Are there any battery error messages?
Thank you for your help,

How to Disable battery charging Function?

Hi;
I have a question about charging funtion of my "HP Compaq Business Notebook, 6720s":
How can I disable "battery charging" function in windows 7? Is there any "advanced setting change" or "software" that while battery is in its slot, stop my notebook from charging its battery?
Thanks

After some days trying many methods, yet I haven't find a solution to my problem. Then I ask is there any one
knows which software should I download for HP Compaq Power Management (similar to the software that Huffer
mentioned, but that was for Lenovo) or which registery or BIOS change should I do , so that I can manually disable
charging function of laptop, or at least put a starting level that up to that level, laptop won't start
autolatically to charge battery, because in this manner once that my Battery reaches to below 100%, instantly begin
to be charged & it would decrease its life time. Please consider that because of my power cable is to some damaged, sometimes it suddenly disrubt & cause my laptop abruptly shut down, then necessarily the battery would always be connected tob prevent this suddent effect.
If any one could help me, I would appreciate him a lot.

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.)

Y50 battery charging problems

hello,
received my new y50 a few days ago and began seting it up. the first few hours it was working fine. battery charged up to the full 100%, i then disconected the power cord to let the battery drain down to about 20%. i then plugged it back in and shut the computer down left it charging overnight. this is when the problems started.
waking up the next day i turn it back on to see that the battery is only at 21%. no mater how long i left it charging it did not change from 21%. So i decide to unplug it again to let it fully discharge. while unplugged it ran for another ~hour all the time staying at 21% until i finally shut off out of nowhere.
plugged in the cord and turned it back on, battery shows 0% plugged in, charging. but it never gains any % charge just stuck there. i do some reading online and decide to do the generic power down, unplug power cord and remove battery, hold power button for 30 seconds, then reconnect everything and power up. When it boots up the battery indicator now shows 2% and over the course of the next 10-12 hours it increased by mabe 30% more. the indicator NEVER changes its percent the only way to see the change in the charge is to shutdown/restart.
today is the third day and after many hours of use i got stuck at around 76% (only reaching this number by restarting every few hours to get a new updated battery charge%) since it stayed stuck at 76% for a while i went for the more hardcore fix ive seen online:
power down> unplug power cord>remove battery>plugin power cord and startup on power cord only>uninstalled the microsoft acpi-compliant control method battery driver>shut down>re-installed battery>plugged in cord and restarted. the driver then automatically re-installed itself and brings me to where i am now.
now a few hours since doing that im up to 83% charge, but same problem remains the only way to update the charge % is by restarting/shutdown and occasionally i can remove the power cord and plug it back in while computer is on and it will update.
Any advice or suggestions on what to do, the 2 main problems i see are:
1. battery charge % doesnt update dynamically, requires power down of some form to update it
2. over 24 hours of being 'plugged in,chargin' just to charge ~80%

i have found the culprit to the problem, but it is one that doesnt make much sense to me.
if i try to install the intel video drivers from the y50-70 drivers page in lenovo support, or if i try to install the intel video driver from windows update, i lose the functionality of the battery indicator. it does show when its connected to ac or runnig on battery power, but it wont update the % load nor time remaining. only way to charge to full is when off.
i did ANOTHER fresh install and am currently running with all drivers installed except for any version of intel video driver and the battery indicator and charging times when powered on are functioning.
any chance to get new intel video drivers for win 8.1 for hte y50-70?

How to change battery charge settings in Windows 8

On my previous Thinkpads I could change the battery charging settings in Lenovo Power Manager. (things like minimum charging threshold, etc). Now in Windows 8 Lenovo seems to have abandonded the Power Manager, but there is still a power manager driver. Is it still possable to change the battery charging settings?

Yoga S1 Can we turn off battery charging?

I am a new user for the Yoga S1, but I was wondering if it is possible to turn off battery charging. I mainly use my laptop at a desk (so I rarely leave it unconnected from Power Plug). I know this is bad for the battery. On a dell that I own (Inspiron 14z) i can turn off battery charging when the laptop is plugged into the ac power plug. Is this possible w/ the lenovo yoga S1? The closest I've gotten to doing this was seeing an ability to turn off battery charging via BIOS, but that is only temporary (when comp is off and unplugged to switch out battery).
Any suggestions woiuld be greatly appreciated.

But why turn off battery charging, makes no sense in this case. You either run off the battery or plug it in and run off the battery while it is charging.
The power draw won't change appreciably.
My bad power consumption will change
It would seem the best strategy would be to get on with a fully charged battery plug in the laptop and let it trickle charge as you use it. Given the length of the flight this should give you the longest use with the minimum amount of draw from the seat outlet.

My Lenovo S890 battery suddenly drains in minutes

Just last night I realized that my Lenovo s890 has been shut off due to battery drain from full charge to 0 in minutes...So what I did is to recharge it again and to my amazement, in under 30 minutes it has fully recharged, but when I unplugged it from the charger there's the battery notification display rapidly counting down...I have checked online for general topics on this matter and tried all the suggested tips and solutions but to no avail...My unit is still under 1 year from date of purchase...please help...

I'm surprised and at the same time disappointed that nobody had offered any input to sorts of troubleshooting to somehow give a semblance of solution to my unit"s problem, or perhaps this is a first type of a problem of its kind thus, no one could come up with any clear solution...Anyway, I have done some tinkering while waiting for replies, and I believe I have solved my own problem, and decided to share with you guys for reference if ever you encounter this same problem:
I consulted years-old forums about android phones quick-battery loss problem and picked out potential solutions there such as:
1. Not using the Facebook app since its using lots of battery juice by posting notifications which come minute after minute; and instead just use the FB in the built-in browsers which consume very little battery juice...
2. Tried the full battery drain then recharge 10 times, and after 4th recharging, there already is a significant normalization of my battery life, On this 4th recharge, I got full battery by 7am. After 16 hours, its only down to 66%, and that's with a considerable amount of Wi-Fi connectivity.
3. I also suspected a particular screenshot app as a culprit for the sudden rapid battery drain, as if this app has caused my Lenovo's battery draining behavior to go haywire. Upon uninstalling the app, the draining behavior of my battery gradully returns to normal...
4. When this rapid battery draining happened, I had the combinations of Lenovo Battery Saver, NQ Power Booster, and Green Power Free apps which I all used to monitor and keep my battery life at check...then after the "incident" I stopped using the said apps and replaced them eith Super Battery Saver and Juice Defender which were effective when I still have my Lenovo A90, at first there was a semblance of normalization in my battery life but with this screenshot app[which I also uninstalled with the 3 powersaving apps, then re-installed with this 2 replacement battery saving apps] the battery draining was still fast, which continued even after the second uninstalling of the screenshot app. What I did is to uninstall Juice Defender and Super Battery Saver and replace it with Lenovo Battery Saver and Green Power Free but to no avail...Next move: replaced the Lenovo Battery Saver and Green Power Free with Juice Defender and NQ Power Booster, and upon the said 4th recharging the return to normal battery draining behavior...
The full-drain then recharge 10 times is still on and I'm still monitoring my unit's battery draining behavior...I will be posting updates...
