Lenovo U410 Battery Sudden Drop to 0%

Hi guys n girls,
I just got Lenovo U410 Windows 8 in February 2013. This afternoon when i was using the laptop in power saver mode, I was able to use an hour from 60% to 48%. After checking the battery percentage when it was at 48%, 5 minutes later the low battery warning showed up saying the laptop has 6% left, then it shut down itself.
Following are the situations:
I seldom use it and I left it for 1 week plus, and two days ago I used it for 15 minutes, and then I took it out n used it today.
I used it in power saver mode.
I was running the windows update.
Steam was on for updating.
I was running open office.
Is this normal ? Does this happen to others ? IS there a way to solve this ?
Thanks
Solved!

hi evanicle,
Upon checking the Lenovo Energy Management, the battery gauge can be found in this location (see spoiler)

Is this what you see?
Hope this helps

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...

Lenovo IdeaPad Z410 Battery Suddenly Drops From 100% to 0%

I have had my Lenovo IdeaPad Z410 since around January, and I have just recently expierienced the problem of the battery dropping to zero. What happens is my battery will be draining at a normal pace then all of a sudden my laptop will shut down and will not go back on as it thinks the battery is dead. If it is plugged when this happens then the orange battery low light will begin flashing and the message goes from saying "Fully charged (100%)" to "1% remaining (plugged in, charging)". This is quite annoying as I cannot take my laptop anywhere without fear of it randomly dying on me. I would assume I wouldn't need a new battery after only having the laptop for a few months. Also, if you are not familiar with this model, the battery is built in internally so I cannot try removing it and putting it back in myself. Any advice would be appreciated; I'd rather not deal with Lenovo's customer support unless I absolutely have to.

hi LordMothim,
Welcome to the Lenovo Forums.
Based from your findings, it's possible that:
- the battery circuit inside is not working to unload the charge, or
- one of the battery cells have already reached its life span
- the chip that handles how the battery gets charge/discharge and checks the charge level of each battery cell (both are controlled by a firmware) is malfunctioning.
Batteries degrade overtime due to heat and daily use. If you're still under warranty, I recommend you contact lenovo and report the issue as you most likely need a replacement battery.

Thinkpad T60 battery sudden drop

Hey,
I bought a T60 Sep 2007. Recently I am having a problem with battery life.(My battery is not on the list of recall)
My battery life went down drastically. It used to be a couple of hours, now it's less than half an hour. Power mangment reports a copule of hours remaining, until it gets down to about 85%-90%, and then suddently drop to 5% and a few minutes remaining.
I seldom use battery and most of time use AC. Interstingly, after charging my battery to 20% or 30%, it can last for half an hour or so. So I suspect there is something wrong with software rather than a physical problem.
Any comments or solutions?

That type of behaviour is typical if one or more cells in the battery are bad. You should look into replacement options.
What condition does Power Manager report for the battery?
Good luck andlet us know.
Cheers,
George

T430s battery capacity sudden drop

Hi, I have a look at my battery report today and found something really awkward. I bought the computer seven months ago, and the battery start with Design capacity 44,000wWh, while the full charge capacity is quite closer to the design capacity. However in the battery report it shows that two weeks ago the design capacity suddenly drop from 44000 to 40734mWh in one week, and then afterwards it drop to 39000mWh. And the actual full charge capacity seems to linger around 37000mWh. Is there something wrong or is my battery just wear out naturally? Best,Eddy

Full charge capacity will decline with battery age and number of recharge cycles. Lenovo warrants their batteries for 1 year. IIRC if the full charge capacity drops below 80% of design capacity in the first year you are eligible for a new battery. 80% of 44,000mWh is ~35,000mWh. I would keep an eye on full charge capacity over the remaining 5 months of your warranty.

N97 mini battery level drops suddenly

I've observed my N97 mini's battery level dropping abruptly from 4 bars to 1 bar (with low battery alarm). The phone's slightly more than a month old and using the latest 11.x.x firmware. Did a bit of googling, and found several suggestions on how to save battery (turn off everything 'smart' on ur phone). That's not the point anyways. I need to find out why the battery level drops suddenly (like what happens when ur battery's dying out), and *not* why the battery lasts X hrs. I'm not sure about this, but I think this mostly happens when the battery level is slightly below max, and I use any app that needs the GPS functionality. But then, there doesn't seem to be any problem with the GPS hardware in the phone, 'coz it usually gets a GPS lock in less than a minute (mostly within seconds). Could it be related to the algo used to show the battery level, or is it that its my battery that's faulty? Any others out there having the same problem?

It's understandable that the batterymeter is not linear (atleast the charge/discharge rates are not). But what bugs me are those sudden erratic drops within minutes (a couple of minutes at times). Anyone who has spent a few days with a dying (rechargeable) battery would know what I'm talking about. It's not a good feeling when u r away from a charge source, and you decide to use one of those power hungry things (like Wifi/GPS) thinking you still have sufficient juice left...and then bam! ... the low battery warning! you just switch off everything, and hope that it lasts till you reach the next oasis. I guess I'd have to analyze this a bit more to understand if its some specific app that causes such behaviour (as mentioned in my original post, i doubt the GPS apps currently). If it happens too often, and even with 'normal' voice+text kind of usage scenarios, its time see Nokia Care I guess. The reason for this post is to know if this behaviour is observed by other N97 mini users as well..then I know there's no point in taking it to Nokia Care.

Lenovo T500 battery stays on %100 for awhile then drops down to %99 for no reason

Hi,
The Lenovo T500 battery stays on %100 for awhile then drops down to %99 for no reason. What's up with this and how do I fix this issue? My laptop is really confusing me. The green battery says it's totally charged %100 and the little AC adapter icon in the system tray says "%99 available (plugged in, not charging.")
Thanks,
Liz

Hello Liz,
that is considered to be normal.
It´s bettter for a Li-ion battery not to be charged fully, so the powermanager don´t load the whole time.
That´s why the percentage could drop. But thats not a problem thats a feature.
if your battery handling is set to automatic in powermanager then, eveythings is ok.
Do you use your machine with AC plugged in the whole time?

Sudden drop in battery performance?

I've had my iPhone 3gs since release, been more than happy with the battery performance untill the last two days. The battery is dropping 2% at a time suddenly. Very quickly. I have restored the phone. I am getting concerned. Any ideas?

Lots of threads about this. Seems to be an issue with the 3.0.1 update or the way it affects certain apps. There are a couple step-by-step tutorials about resetting the battery sensor, restoring as a new phone, etc. Try one or all of those and see if it helps.

Why does the magic mouse battery level drop suddenly?

I typically get, oh, about 3 weeks off of a pair of AA alkaline 1.5V batteries on my magic mouse.
What I don't understand though is not really being able to track the battery level in the bluetooth menu on my iMac 21.5".
The battery level even now is at 100%. What happens is is that it stays at 100% for several weeks and then all of a sudden drops to 7% or so, and I get a low battery warning. Then after a couple of days the battery will drain out.
After it drops down to 7% I can usually track the battery drain in the menu. But I never see it at 90% or 80% or 50%, etc. It just drops down suddenly near the end of the battery life.
Do other people see more continuous changes of the battery level?
The same thing happens with my bluetooth Apple keyboard that came with the iMac. Right now it is showing a level of 100%. It typically lasts for months instead of weeks, but I will never see an in-between battery level value until I get a low-battery warning.
I'm thinking of rechargeable batteries for my magic mouse. But I see too many negatives posted here in the forums about that, so I am hesitant about investing in those batteries and a charger if it's not going to work well.
Thanks,
doug

Maybe it's a Mac model issue? I'm running the late 2009 model, purchased in February 2010, and running Lion.
But I've never seen the battery level display in-between values.
Here's what it is showing now and I replaced the batteries over a week ago.
Do your batteries also last a few weeks in the magic mouse?
Thanks,
doug

1950-Battery level drops suddenly to 5%

Hi,
I have a Satellite 1950-902. I was wondering if someone could help with the following problem/unusual behaviour that began about a month ago:
I start using the laptop with the battery showing up as being full in Power Management. After about ten minutes of battery use, as soon as the battery level shows as being around 85%, the battery level indication suddenly drops sharply to 5%, and the system hibernates. When I recharge the battery, the charging process takes a very short time (about half an hour).
This behaviour is repeated every time I use the battery now.
What is going wrong?
Thanks.

Hi Eleni,
It sounds as if some of the cells in your battery may have failed and consequently the battery can only hold a small portion of the normal charge. I would suggest a new battery is called for.
regards,

Sudden drop in battery performance / condition

I have a late 2010 MacBook Air. Battery suddenly says "Service Battery". Was away for 11 days and when opened air to use noticed this?

Do what it says. If it's the MBA's original battery it's probably due for replacement.

Lenovo U410 - Wifi disconnected when connected to USB.

Hi, I bought a Lenovo U410 sometime in July 2012 (bought it back home in Malaysia). About a week or two after I bought it, the laptop sleeve cover came off, causing the laptop to fall to the floor. But fortunately, other than a small dent (pictured) at one corner of the laptop, everything seems to work okay. [well, if you plug in an earphone, only the right side would play but I'm not too concerned about that] I've enjoyed using the laptop, everything works fine & easy for me. I use it mainly for my studies (I'm a rising junior in Madison) and occassionally some photos & video processing. Other than The Sims, I never actually used my laptop for 'gaming' stuff (was planning to soon though). But recently, in the past few months, I realized that there's something wrong with the laptop. It connects to WiFi just fine and everything, but whenever I connect my external hard drive to my laptop, my Wifi would disconnect automatically & wouldn't reconnect until I remove the hard drive. This happen even when I connect a USB port to the laptop, but doesn't happen when I connect a small USB pendrive or my phone (Samsung Note 4) or a bluetooth speaker. Not sure what's the problem with it, and I'm a noob when it comes to things like this, so I would really appreciate your help. Thanks in advance!

Hi syazanazura,
Welcome to Lenovo Community Forums!
The Laptop maybe having power issue since the drop.
You can try opening
Control Panel / Hardware and sound / Power Options / Change plan settings on selected power plan / Change Advanced power Settings
Now look for the Wireless Adapter Settings Make sure not to use the scroll but use the scrollbar to the right
Open the Wireless adapter setting and make sure that both plugged in and on Battery are set to Maximum Performance.
Let me know if this works for you

Lenovo U410 Urgent Help Will Not Turn On

Hello,
Firstly i would like to thank anyone reading this post and taking the time out of their day to try and help my problem.
I have a Lenovo U410 Ultrabook i've had my Laptop for around 1-2 years now and i have kept it in a very good condition there have been no issues with it. About 1 Week ago i was using my laptop left my room for about 30 minutes to have a shower and upon returning i saw that my Laptop was not charging i unplugged the charger from the laptop and place it back in nothing happened. so i turned off my laptop and unplugged the charger from the wall socket. since then i have not been able to turn my laptop back on i have tried but the led's flash twice when i tried to turn it back on. i have changed the fuse in my charger about 3 times with new fuses all 3AMP required and there is no difference at first i thought it was a problem with the charger but now im thinking otherwise and i'm quite worried. After searching around the internet for a fix i have pressed the power button for 30 seconds and the leds blinked 3 times and after trying various methods to turn it back on it has not been succesful i have even uplugged the battery and plugged it back in after removing the back cover. i have no warranty left as it expired and i was not able to renew it. if you have had any experience with similiar problems or any suggestions i would be very interested to hear what you think the next step for me would be. i dont have much money to invest into this laptop but i am prepared to spend some money if need be.
Thank you for reading my extremely long post,
Your's faithfully

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?
Moderator note; post moved to here to start new thread, subject edited

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?

When I am on Firefox, my Netzero email page suddenly dropped to very small print. AOL OK. How do I increase size of the print so I can read the email?

I was using Firefox to read my Netzero email. The print suddenly dropped down to very small and I have difficulty reading the email. Netzero said to oper Mozilla Firefox, click "tools", click "options", and click "content" to change the font to a bigger size. But when I clicked the brown "Firefox" button on the Firefox page, I do not see the buttons Netzero told me to click. Can you tell me what they are referring to or just tell me how to increase the size of the font when I am reading email on Netzero. AOL email font size was not affected when I clicked AOL to read the email there.
