I've bought E50-80 a bit more than month ago, and something is wrong with battery.
Battery charge % drops suddenly from 20%-30% to 6%.
It looks like battery is damaged.
I am using Windows 10 and have current acpi drivers, and all stuff from lenovo download.
I am really disappointed, it's my first time with lenovo notebook and its really worrying.

Welcome to Lenovo Forums.
Sounds like a defective battery to me but first I l try to investigate to fix the problem.
Go to your power management settings (control panel > power options)
change the default behaviour when you close the lid of the laptop to "shut down" (i'm sure it's set on sleep, or hibernate)
check out what the power button is set to do...it might be set to hibernate or sleep instead of shutting down.
Take your time, go through the advanced menu looking for power settings that indicate this laptop might be hibernating or sleeping rather than powering down.
You could also try a "hard reset" for the PSU:
Note: To perform a hard reset, unplug the AC power adapter and remove the battery, and then press and hold down the Power button for about 6 seconds. This will drain any residual charge in the capacitors and reset the power management controls to their default condition.
Let us know how you get on.
