Re: Ideapad 700 15ISK: Computer Shutting Down at ~50% Battery

2018-06-25, 3:58 AM

battery gauge calibration does not require any application you can do it manually..

 

here,
when your battery goes to 0% charge it 100%
and do not unplug charger let it charge to for 3 to 4 hrs on 100% , let it overcharge (you can do light use of laptop during that charging process),after doing that unplug charger,

 

during discharging do not use laptop let it discharge just ensure that your laptop do not goes to sleep mode or screen sleep you can adjust these setting in battery options in windows settings.

 

after that battery will discharge to 2 to 3% or it will shut on on 50% let it shut down and charge your laptop again to 100%
this time do not overcharge your battery.

after 100% charge,unplug charger use your laptop check does it shuts down.

If it's that so, then try to replace your battery instead. Maybe that's the only option left, and let's see what happens.

I can suspect battery gauge fault in your system if a new battery won't solve your issue.

I have Vantage installed, but I can't seem to find the battery recalibration option. I've checked the 'Power' menu under 'Hardware Settings' but don't see anything.

My 700-15ISK was supplied with the older "Lenovo Settings" application installed, and I have not yet updated to the current "Lenovo Vantage".  I have just looked at "Lenovo Settings", but it does not have the recalibrate function.  I thought that "Vantage" does, but perhaps not.  Sorry for the bad advice.

 

If you want an application to perform the recalibration, you could use one of the older Lenovo "Energy Manager" applications.  On my 700-15ISK I have both Windows 10 and Windows 7 installed, and I use "Energy Manager" on Windows 7, in particular this one:

 

 http://pcsupport.lenovo.com/gb/en/downloads/DS100173

 

This does have the recalibrate function; it is called "Gauge Reset" (click the menu icon at the top right of the energy-manager panel).  I have never used gauge reset, so I cannot confirm that it performs a useful function.  However, I did try installing "Energy Manager" on Windows 10, and it does work, even though it was originally written for Windows 7/8 and older Lenovo laptops.

 

Laptop batteries have a limited lifespan, and you should expect to have to replace it after some period of time.  Also, style of use may affect useful lifespan.  I don't know whether your battery is now at the end of its useful lifespan.

Probably your battery is dead,

here one thing that  you can do , take another similar battery from your friend use it on your laptop or take your battery and use it on another laptop and check whether the battery works or not. if  battery from your friend is working well then thats not your laptops fault, replace your battery.

Re:Ideapad 700 15ISK: Computer Shutting Down at ~50% Battery

I'm facing the same thing. My laptop-T460 drop when the battery is 50% (actually: battery1: reach 0%, battery2: 100%). If I turn on my laptop again, it will start using battery 2.

 

Any solution?

Possible fix:

 

1: Test your battery

2: If it's good, DISABLE Windows automatic driver updating

3: Remove Lenovo power/battery management programs and drivers

 

1 - TEST YOUR BATTERY: So, in order to truly test your battery, do this: Charge your battery to the max it will go to. Reboot/power on the computer, and then open the BIOS on startup, and use max brightness on your screen. Then, unplug it and time how long it takes for the system to die - and that's it. If it lasts awhile, your battery is still good. If it dies quick, your battery is bad. The BIOS has ZERO power management and there will be nothing to get in the middle of the battery being fully discharged. It will go like a car with the gas pedal stuck down until it runs out. I did this when my system was crashing, and it lasted the 50-60 minutes that I was expecting. This showed me it had nothing to do with the actual cells going bad... especially since it was new. Side note: This method can be used to re-calibrate your battery, if it's still actually working right.

 

2 - DISABLE WINDOWS AUTOMATIC DRIVER UPDATES - Right click This PC on your desktop -> Advanced System Settings - System Properties -> Hardware -> Device Installation Settings -> NO.

 

3 - REMOVE BATTERY/POWER DRIVERS, DONT ADD MORE:

Right click This PC -> Manage -> Device Manager -> View by Connection -> Look alphabetically for Lenovo XYZ power management/battery management and UNINSTALL AND DELETE DEVICE DRIVER. Also uninstall the Microsoft ACPI-Compliant Control Method Battery BUT DO NOT ERASE THE DRIVER FOR IT. Also get rid of any Lenovo power management software in your software lists - you don't need it. I've never needed it for my W530, ever.

 

4 - Reboot. See how long your system lasts now.

 

Immediately after removing the Lenovo battery device driver, I tried using my BIOS hacked W530 laptop unplugged with a 3rd party battery. I've now been typing this tutorial for the last 35 minutes.

 

Hopefully you can now enjoy being mobile!
