Re:T480: Does not switch to secondary battery, turns off unexpectedly (Win10)

2021-02-02, 18:39 PM

Hi guise 

 

I have Lenovo T450s Series. I had this problem too. 

I want to share my experience about this. (Does not switch to secondary battery, turns off unexpectedly). Problem resolved.

I calibrated two batteries with Lenovo vantage software with this steps:

First : Install Lenovo vantage from Lenovo website

Second : Opened Device Menu in right top of screen and in Device setting opened Power and in Battery setting select Battery gauge reset,

and at first reset SECONDARY BATTERY and then reset PRIMARY BATTERY. 

 It need long times to complete process. 

 

Regards

Ali:

 

It is good to hear that it worked for you as well.

 

It seems kind of silly, but if it works ....

It's not silly  ;-)

 

thanks for the post!

Jim

For me the vantage battery-capacity reset procedure was helpful.

I have no idea why, as the before and after values were not very far apart ... but it did help.

Great, I just noticed my T460s has this problem.

 

I have 2 hours to get this to a new user, already spent one hour running diagnostics while it cut off just before finishing. I'm going to see if I can try the vantage fix before time is up.

 

Thankfully, batteries are not an important feature of laptops
