Yoga 720-15IKB Laptop spontaneously turns off when unplugged

My Yoga 720-15 laptop spontaneously turns off when not plugged in, despite being at 100% battery power.

I ran Lenovo Vantage to update my BIOS but when I run the update software, I get an error message saying "Please insert system battery."

Any suggestions on what is happening? I am worried a battery connection has come loose.  No trauma incidents I can think of recently to have cause this.

When plugged in, the computer stays on.  But I am still unable to update my BIOS.

Hi Zev1!

 

Welcome to the Community,

 

Laptop turning off immediately once the charger is unplug could caused by a faulty battery. In BIOS update, battery should have at least enough charge (In some, 30% charge is needed). The BIOS is not working since the laptop is now relying on the power source. You can use the guide here on how to open the back cover and check the battery connection,

If the laptop is still within the warranty, we would suggest to contact our support at 877-453-6686 / 24 hours/day 7 days/week so they assist you in setting up a service for your laptop.

 

Regards,
