My y700 is only 6 months old, Im suddenly getting only 2hours backup on battery, shows only 2 hours remaining when charged fully and it doesnt even last 2hours if observed closely. Its not that im gaming or using very heavy workload program something, Yesterday i fully charged the battery used it in 40% brightness and streamed 480p videos on youtube, it didnt last 2hours! Whyis this happening? shouldnt i begetting 5 hours on battery ? help please.
One more thing i noticed the laptop tends to be warm all the time, not like super hot while gaming, even when siiting in idle the keyboard part feels warm.

Thanks for using the Lenovo forums.
By the sounds of things, the battery may be failing.
Try to see if you can run an LSC hardware scan, see if that can find any issues.
1. Please click on the following link
2. Under the section ‘Download’ select the relevant Hyperlink dependant on whether your Lenovo is running Windows 7/8/8.1 32 bit or 64 bit.
3. When prompted, select save and browse to a drive and directory in which to save the downloaded files.
4. Navigate to the folder where you saved the installation file, lscsetup_x86_26001.exe.
5. Double-click the installation file icon to start the installation.
6. Follow the onscreen instructions via the installation wizard that will install Lenovo Solution Centre on your system.
7. Once installed you will have a ‘Lenovo Solution Centre’ icon on your desktop please click to open this.
8. Once solution center is opened please select ‘Checkup’ then ‘Hardware Scan’ and ‘Full Scan’
9. This will take up to 20 minutes, see if this can find any errors.
Also, try a static discharge for this, it may help to resolve the issue or at least get rid of any built up static on the motherboard that could be causing an issue.
(If the battery is internal, please just skip the remove/replace battery steps.)
1. Turn the unit off
2. Remove the battery and the Mains adapter
3. Press and hold the front power button for 30 seconds
4. Replace the battery and the Mains adapter
5. Turn the unit on as normal
Also, you can try to do a gauge reset.
Note: make sure the AC adapter is plugged in when performing a gauge reset.
1. Go to Power Manager
2. Battery tab
3. Battery Maintenance.
4. Click "Perform Reset"
See if any of the above helps, if these steps do not work or you would like more info on this issue you can call your local Lenovo support line. Below is the link to the phone list where you can find these numbers
Hope this helps, let us know how you get on.

Hi, I don't know if your problem is solved yet, but I'm having a the exact same problem with my 6 months old ideapad y700 15ISK.
After a lot of searching and trial and error, I decided to delete the power management driver, since it wouldn't start anyway and immediatly I saw my remaining time rising to 3.5 hours. Right now, after about 10 minutes, its up to 4.5 hours so it seems like this solved the problem for me.
Hope this information can help you or other people facing this problem

I simply went to the drivers folder on my C drive and deleted the 'Energy Management Driver' folder.
Unfortunatly, my battery has fallen back to 2 hours when fully charged. I noticed that after my remaining time had rosen to 4 hours, it fluctuated between 2, 3 en 4 hours and now I'm stuck again with around 2 hours.
It is still fluctuating though, one minute it says I have 1 hour and 40 minutes left and the next minute I only have 1 hour and 20 minutes left, then back to 1 hour and 40 minutes while my battery keeps draining.
In 1 minute my battery has gone from 88% to 83%.

The remaining time on a laptop's battery is mostly a windows feature and not linked to lenovo unless you install the Lenovo Energy management software and use that.
In my experience, this time fluctuates based on current usage, so say if you start playing a youtube video you will see that within a min or 2, battery remaining time can go down fast. If you stop the video, the battery remaining time will go up again. In reality, the battery just doesn't have enough power, only when in standy mode it will show higher remaining time.
Try using battery saving setting/Balanced rather than High performance.
So, the question is - Did your laptop battery provide more run time when you received it?
If it has dropped considerably, then you can click on Support link on top of this page, enter the laptop information and start a warranty case to replace the battery.
AFAIK, the high performance laptops usually don't run for more than 2-3 hours. It is really difficult to get 5 hours out of such gaming laptops, even if you are not gaming.
I have a Lenovo Yoga 900, which is purely a work/multimedia ultrabook and it provides me between 6-8 hours of battery life, whereas my Y700 lasts for 3 hours.
