Battery Express Charge Missing

Hi,

I got a second Yoga 720 15IKB just this past month and noticed that there is no express charge feature for this recent laptop that I purchased. It's the 1TB 4K model platinum silver. I noticed it has an LG battery in it.

 

My previous purchase back in november of 2017 was the 512GB 4K model in iron grey. I noticed it had a CelXpert battery or some sort. This one does have the express charge feature.

 

Anyone know what's up with this?

 

Thanks,

 

Richard

Hi, Richard.

 

I noticed the same on Yoga 720-15IKB.

Unit with mfg date 11.2017 has express charging, but unit with the same P/N with mfg date 09.2017 has not (different internal battery).

@dschapov, how did you get a manufacturing date on the laptop?

Re: Battery Express Charge Missing

Can anyone from lenovo comment or weigh in?

 

I tried tech support, but they were ineffective and unknowledgeable about express charge. They first thought that conservation mode, where you only charge up to 60% was the issue. They also tried reinstalling lenovo vantage to no avail.

 

This really should have been documented if it is available with whatever conditions necessary for express charge to happen.
