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

My laptop is unexpectedly turning off when it reaches around 50% battery, but the actual level can be anywhere between 40% and 60%. It never turns off when plugged in. Whenever it does shut off, I have to plug it in before it turns back on. I thought maybe something was wrong with the way the laptop was reading the battery, so I updated the BIOS. Right after updating, the computer reached 20% without turning off so I thought the problem was fixed. But the next time I used it, it shut down at 40% again.

I know its not a heat issue because it happens whenever the laptop isn't plugged in. I thought maybe my laptop is reading the battery wrong but I don't know how to fix it. I've already completely reinstalled Windows.

Some people suggested manually calibrating the battery by fully charging, discharging, and then charging it again. I can't do this because the computer shuts down before it gets to 0% battery.

AAA-Cindydog 5.pngYou've no doubt done this but have you updated driver's, ect?

That may help especially after updating the bios..

Your battery may be dying. You may need to replace it. Go to the Lenovo Service Center and ask for battery replacement. Use your warranty if possible, it will help.

It appears as well that your battery is no longer calibrated. It may also show signs that your battery is dying. Re-calibrating it will be difficult so just keep the AC Adapter plugged in.

Try to go to Lenovo Vantage and look at your Battery Condition. Is it bad? If yes, replace it. If not just reply. I'll see what I can do.

Lenovo Vantage says that my battery condition is 'good'.

Hmmm okay...

Maybe try to repair and reinstall your battery drivers? I'm not sure if that will solve it but just try. Make some backup as well if anything goes wrong (like a restore point.)

Uninstall your microsoft apci driver in your device manager. After reinstall it. If it does not work, try the other driver. Make sure you backup your files and make a restore point before doing this.

I reinstalled both battery drivers but the battery is still shutting down unexpectedly.

I see.

That's weird...

Maybe you need to replace your battery, even though Lenovo Vantage says it's good. It may say it's good, but it does not say how good it is.

Once you buy a new battery make sure to calibrate it once per month, like literally a full cycle - from almost 0% to 100%.
