Lenovo Z50-70 turn on only with charger connected

[rikomitsui]

My Lenovo Z50-70 turn on just if is connected with charger. If I try just with the battery it makes a noise nothing else. But when I turn on the laptop with charger it works well also if I disconnect the charger. Zny idea?

How long is it work from fully charged battery?

At least 3 hours!

Have you tried to remove battery and unplug power cord, then press power button for about 15 sec(without battery and charger cord), and then try it again.

Not yet...Im going to try!
