Malfunctioning laptop battery?

[DapDingo]

Greetings,

My laptop battery is not charging correctly. I've scoured the internet for solutions, but this one seems unique. The ONLY way I can get the laptop to charge the battery is if I do the following steps in the exact order:

1. remove battery, 2. unplug charger from laptop, 3. unplug charger from outlet, 4. plug the charger back into the outlet, 5. plug charger into the laptop, 6. turn on the laptop, 7. then finally put in the battery.

After those steps, the battery charges fine. If I do it in any other order, the battery does not charge. My specs are the following:

Lenovo Y400
6-cell battery
Stock charger
Windows 7 64
MSATA SSD

Things that I've tried:
1. Reinstalling the OS
2. Disabling/updating battery device drivers
3. Using another charger. I have to do the exact same steps as above even with a different charger that I know works fine.
4. Different outlets

Thanks for any responses,

Sounds like the charging controller circuit on the motherboard is malfunctioning. How does it run if you remove the battery completely and run only on the A/C adapter-charger? It would also be helpful to try a different battery, if you can access one.

I don't need the battery to start the laptop. I can start the laptop by unplugging and re-plugging the charger from outlet and the laptop. Unfortunately, I don't' have access to another battery I could try.

The most similar problem I could find was Lenovo's battery not charging after using guage calibration, but I've never done that:

Are you saying that even without the battery installed, you still must plug and unplug to start it?

Yup, that's correct. Now that I think about it it seems more like a mobo issue than a battery.

Thanks for the responses btw.
