I bought my Lenovo laptop new from a shop so as far as I know the battery is legit.
Most times when I turn on my laptop, I get a message from Lenovo informing me that the batter is counterfeit or at least not a Lenovo battery.
When this happens, it only lasts about 1.5 hours. However, on other occasions it can last 3 hours.
This time information is displayed by hovering over the battery icon on the taskbar (Windows 7) and even when the battery has a full charge - i.e. before I've been using it.
I'm doing the same stuff whether it lasts 3 hours or 1 hour - the counterfeit message seems to make a difference.
Any idea what is going on here?
Thanks!
