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

Hi All,

 

just found this thread. Unfortunatelly I don't see that issue on any T470 here in the Lab. Could you pls let me know what is your removable battery vendor pls ? Either run "powercfg /batteryreport" and check the HTML file or "wmic path win32_battery get /format:list" to check the vendor. Thnx.

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

Thnx Chris, need to get more people to confirm that all of you seeing the issue have SMP battery as all machines here have Sanyo. We have ordered SMP to doublecheck in the LAB.

@elmatkos: thank you for your help on this issue!

In Lenovo Settings it states that both my batteries are from SMP.

Running "powercfg /batteryreport" confirms that I also have SMP batteries (both internal and external).

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

[ Edited ]

Maybe because I've got next day call out I could ask an engineer to bring a Sanyo. Might make sense.

 

Well.... I just called them and they told me that my "part has been delivered".... They didnt seem too happy to explain what that meant as I was meant to be having an engineer visit on Monday and a phone call. Apparently the engineer is with me in my office that I'm 10+ miles from and certainly not being seen by!

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

Thank you all for confirmation, I hope that I will get the SMP battery soon to confirm that behaviour here in the Lab. If anyone get battery replaced for Sanyo, pls let us know if you still see the issue so we can doubleconfirm. I will let you know ASAP if I find something usefull.

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

Both batteries are SMP, though CPU throtliing (0.35 - 0.38 GHz) only occurs on external battery for me.

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

Guys, if you can run just the "powercfg /batteryreport" again and send that HTML report to me at EMEAtech1@lenovo.com, I would appreciate that. There are all the details about the battery, like date and FW, so in case the issue is really connected to that SMP battery, I will have more details for our Product Engineering. Thanks a lot.
