Hello, I've just bought a second hand T440, and windows 7 tells me that battery #1 is "missing" (battery #2 is ok).
If i take out the external battery while in BIOS or Windows, the computer shuts down, so I believe it's not a driver issue.
My BIOS is up to date (2.29), set to default configuration.
Do you think it's a hardware issue?
Thanks for your help

I think whoever you purchased this second hand laptop off of removed your internal battery. that would just be too **bleep** funny if that were the case. "I don't think it's a driver" LOL no your battery is missing! read the error message agin!
Hey at least you benefit from the reduced weight! LOL
Always buy new or certified refurbished parts

II have a brand new (1 Week Old) T440s with the same problem. Battery #1 isn't detected. The unit has 12Gig of RAM. Hopefully I don't have to crack the case to see if it is there, but I suspect it is there and perhaps it failed in some way. Has anyone run into this issue and found a solution? Windows 8.1, BIOS 2.29

Thought I would follow up on the resolution... The laptop was shipped from the factory with a defective internal battery.
I am now able to swap batteries without dropping the OS, but I have noticed that when you do this the battery meter no longer shows the two batteries separately. and even though the 6 Cell was fully charged and the internal was at 46% when I swapped batteries it now says there's 46% remaining. The meter information is completely unreliable.
