Re: Lenovo T470 (Core i5 7200u)- Slow performance on battery

I am from VietNam. My company just bought 116 laptops lenovo T470. But they got the same issue when they run without battery. I tried to update the latest BIOS version 3.19 but the issue still presist.

Following the instruction above, I unplug the extend battery, it work so fast.

Hopefully, Lenovo can have the solution or release the new BIOS version for fix this issue.

I still haven't received my replacement battery from Lenovo and support is not communicating any status updates. MTSA status is: HP Hold for parts.

just unclick the external battery. You'll have half the run time but you'll have a laptop that functions normally

That's not a solution when I need more than a few hours on the go.
