Installed BIOS update 39 and I now get the 10% warning message. Battery drops SUPER fast though. Dropped 20% in 10 minutes... Not normal. I've got the 8.1 windows and the 8.1 energy manager but I'm gonna try and install the 8 instead and see if the battery runs normal again... At least it doesn't drop from 100% to 0% anymore lol

No, the battery meter on the energy managment says it is fine and it did work intermittently giving a warning but as of now it is the same problem, laptop stuck at 99% and then shuts off no warning. It seems to be a problem with this model of laptop, a quick search shows that we are not the only people suffering this. The only remedy I have been offered is to send the laptop back under warranty but this also poses a problem as I need it for work. So it is either suffer the battery issue or let my work suffer. If this is a known issue with these laptops they should not have been sold in a state like this, it is only 7-8 months old and I know the battery life decreases after time but this is a joke, what happens after another 7-8 months when the battery goes again and my warranty is up? I love the laptop bar this issue but this has seriously knocked my faith in Lenovo and I will be hesitant in purchasing another item fromm them.

Yes, even I'm not in a position to send away my laptop for fixing. But, it seems like this issue was earlier faced in the Z500 series laptops and Lenovo released a battery firmware update for fixing it.
Link to the upgrade:
As the information on this download page states, "Z&P400/500 series battery may suddenly stop charging or discharge. Once in this state, unplugging adapter will cause system to power off immediately. This issue can be resolved by upgrading the Batteryfirmware version to 0003_800A_0010_80A3 or later with the Battery Firmware Upgrade file."
Looks like the Z510 laptops were also shipped with faulty battery firmware. High time Lenovo took notice of this and corrected the version. As this seems to be a software issue, it doesn't seem logical that replacing the battery will resolve the problem. We can have the battery replaced under warrenty, and after another 7-8 months, the probem is sure to resurface.

I personally have not been able to fix the solution yet; as of now, I'm just keeping the laptop plugged in when I need to use it and avoiding the battery altogether. I've been too busy to try the OneKey reset or BIOS solutions posted in the thread thus far, but it seems even those are having mixed results to date. At the moment, I'm really not sure how to proceed, but any advice is greatly appreciated.
If we could get a Lenovo representative or Service Professional to weigh in on the situation, that'd be ideal. If so many people are having the issue, it should be addressed in a timely fashion.
