Well I too got the same problem & unfortunately after the warranty expired. So, Im left without any solutions as I've tried'ém all. It's strange that until now they have no update with solving this problem. Totally frustrated! I used it very rarely & only when I'm outside. And now I'm clueless about the battery charge. However, there is just one solution ie. to wait for any firmware update from Lenovo to solve this. ... weeks or months or forever >.< Good Luck !

I have exactly the same issue. I've tried gouge reset twice, ACPI reinstalls, nothing worked ... it seems like a software issue, but i cant figure out which one. I think its software issue, because yesterday, when i tried to ungplug the AC adapter, my computer was able to run on batter for good 2 and a half hour with high performace switched on ... weird ... can somebody reply ?

I also believe that this is a firmware problem, as similar issues were found for the Thinkpad series:
Unforunately, Lenovo doesn't reply to our messages in a clear way, so I am still wondering whether I should wait for a firmware update or get a new battery, also because the latter will not ensure that the same problem won't appear again in a few months.
Since last time I posted here, things are only going worst. Now the Energy Manager says that the battery is weak and I need to replace it, the battery indicator is stuck at 0% and the battery is not charging. So as a result I can use my 1 year old laptop only on AC.
This situation is getting absurd: there are many customers with apparently the same problem, evidences that similar battery issues affected also the Thinkpad series, and no clear statement from Lenovo.
I think it's time for us to undertake more serious actions than just posting on this forum.

I have exact the same issue!
My warranty is expired, I can't get a free battery replacement from Lenovo, PLEASE LENOVO DO SOMETHING! There is many people with the same Issue or offer a free battery replacement campaign independently if we have an active warranty or not, it is a known issue!
Is very frustating not receive any useful help from you, we love Lenovo trademark but issues like this can make a change in our opinion about the company.

I cant even buy a replacement battery. I opened up the case to get the battery number (L12M4F02) but cant find these for sale anywhere in UK, apart from eBay sellers in the US selling them for suspiciously cheap prices. I'm assuming the lack of stock is because this battery has been discontinued due to the number of complaints. I emailed Lenovo for what alternative batteries would work but they just emailed me boiler plate message to check their product page or buy from a third party if I couldnt find the product I was looking for. Thanks Lenovo!

I am also facing the exact same problem.
On top of this my processor is stuck at 0.77GHz and to rectify that the battery needs to be at 30% to update BIOS .
Def not what was expected such a laptop . Hope to see a working solution soon.
