My external battery works fine on OSX.After doing some testing I am having more issues with the external battery. Does anyone else have any issues with the external battery with macOS and the t440s? Does removing and reinserting the battery while the laptop is on work for anyone?
I can get the external battery to work and be recognised most of the time, but when it is inserted just moving the computer around a bit the laptop just shuts off. I cannot get the laptop to do this when the external battery is removed. No amount of moving it around can make it turn off.
This means the problem is either the battery or something else? Could it be something with Bios v2.36? I never had this problem before when running Linux on the t440s for about a year.
Yours is likely a problem with battery capacity or connections. Should be easy to test the battery function while you're booted to windows or on bios screen. If moving it still switched off laptop, it is definitely the connections.
