    Hi,

    I have a Lenovo Z50-70 running Windows 8.1. The laptop is relatively new, bought in Jan. 2015.

    Some time ago, the original battery suddenly started to have a problem where it would say 45% available, plugged in, not charging. No matter what fixes I tried (after looking through a lot of articles, posts, comments, etc.), nothing made the battery start charging again. It always stays at 45%. Also the battery light/indicator on the front of the laptop is always blinking white.

    So I got a new battery, put it in hoping that it would work and charge up to 100%, but the new battery is having exactly the same problem as the original old one! It will only charge up to 45%, then it says plugged in not charging. The battery light is again always blinking white.

    What do I do? How can this be fixed? What's going on?

    Appreciate any help. Thank you very much.

    Do you have any 'battery saver' programs running which limit the charge to 45%.

    Check any and all options that you can find in relevant Lenovo helper apps.

    No battery saver or conservation mode, it's set to be on high performance mode to go to full charge, but still will never charge higher than 45%.

    It can't be that both batteries are bad...

    Is there some setting in the BIOS? That could be stopping this..

    I went into the uefi firmware (from what I Googled it seems there's no traditional BIOS on win 8.1 machines, not that I really know much about that), and there was no settings about battery at all in there, so what else could be causing this?

    What can I do that will make both batteries charge to 100% again, or is there even anything that can be done?

    Are both batteries just duds, or is there something wrong with some internal hardware, motherboard, or internal connection in my laptop that's causing this?

    sounds like a motherboard issue. Perhaps something with the charge controller and its related circuitry with the battery. Impossible to say exactly what, without seeing it.
