I have recently purchased a T530 with Windows 8. I specifically asked on the phone about the possibility to set up battery charging limits since most of the time the laptop will be docked, so I don't want it to sit on 100% charge for weeks at a time (the the sake of long term battery life). They said that the Lenovo battery manager software allowed you to do that, and actually I seem to recall this as an option from years ago when I had a Z60m.
Alas, it seems as though this is not true with Windows 8. It seems as though the old Lenovo battery/power manager is not supported in Windows 8.
Does anyone have any suggestions before I start raising support calls?

Hey there Hopkins and welcome to the forums!
If you will do you have or are you able to install the Lenovo Settings App? This will require you to have Lenovo Settings Dependency Package also installed. The app itself is only available if you purchased a machine with Windows 8 OEM.
If you have both of these installed and ready to go, access the app and select the Power option. Within here you mayhave a battery charging threshold option. It may be similar to the Twist's power selection option, which allows you to charge to either 100% or 50%.
If the Lenovo Settings App is not an option for you, I did find this Knowledgebase Article that may be of some assistance as well. Changing Charge Threshold on ThinkPads under Windows 8 without Power Manager.
I hope this helps.

Thanks for the welcome and the quick reply! I do have the Lenovo Settings App, and that does not have any threshold control - it is interesting that they have implimented something for the Twist but not yet the others. Perhaps this suggests that they are working on a more comprehensive Windows 8 solution.
Thanks for the link to the threshold registry settings - I will try this and report back. The requirement for a restart makes this a little inconvenient (for example, if I know that I will be working away from home the next day then I will want to toggle it into "full charge" mode), but it is much better than nothing.

Ah, sadly this has not worked for my T530. I just plugged it in again but the registry parameters had set back to zero and the battery was charging. I re-edited the parameters and rebooted - now they appear not to have reset but the battery is still charging.

As far as I know, we don't have formal support for setting start / stop thresholds under Windows 8. There are some work arounds as suggested in that KB, but there may be cases where this doesn't work.
We are definitely carrying forward the feedback that customers miss some of these features, and I hope that perhaps they can be reintroduced some way. In the interrim, we'll see if more testing can be done and the referenced article with registry tweeks updated.

Many thanks, Mark. It is nice to visit a company forum which appears to be monitored by the company!
The ability to set thresholds is really important for people whose laptops live mostly in the dock, and it still amazes me that this problem is not more widely addressed by the industry. The old Lenovo Power Manager really set it appart from the crowd.
Would you recommend that I opened some sort of support ticket to register my request/concerns formally with Lenovo?

Mark, thanks indeed for responding, but you are admitting that support for battery threshold functionality was removed by Lenovo ON PURPOSE? Only a cynic could suggest this was a deliberate ploy to sell more replacement batteries.
"Perhaps". LOL. This is really not acceptable I'm afraid. Batteries cost £100+ and are extremely sensitive and delicate and need extreme care to retain charge capacity - as everyone at Lenovo of course knows. Please restore this functionality immediately or supply me with a free spare battery.

I've been wanting to submit a formal complaint/request, especially as when I bought the machine I specifically asked them about this feature and the salesman confirmed that it existed, apparently unaware that this was not true for Windows 8. However, I can't work out how to do it by e-mail - it seems like I might have to make a phone call!
