Battery charge + wi-fi, what's the problem?

Question

laptops

Notebook Lenovo Z510, serves a little over a year. A few months ago, the battery began to discharge "to zero", the charge does not hold well, when disconnected from the network, it is cut down after a minute or two. And a message from some pre-installed Lenovo program, they say, replace the battery. I thought: "That's it, coffin-coffin-cemetery." But I didn’t buy a new one, it works fine from the network and without any complaints.
And it would have dragged on, but ... Once I left the city and found myself without wi-fi. And what do you think? My Lenovo began to charge, keep the battery charged (although several months have passed, a Li-Ion battery in a discharged state is very likely to die). I charged for several hours, left it in sleep mode for the night - in the morning I was completely alive, minus a few% of the charge ...
When wi-fi is connected with a full battery, it is now working in normal mode. (Now it has been standing for at least 30 minutes)
From additional information: after 2-3 months. After the purchase, the Internet fell off via cable (I found it by accident), firewood flew to wireless several times, reinstallation helped.
I read the forums, they say that the battery really often dies, but still, as it turned out, mine did not die.
In the settings of Windows power plans there is a tab "Wireless network adapter settings", and inside "power saving mode". Could it be her issue?
Who has any thoughts? What to do and who is to blame?

Answer 1

Lenovo did not have any specific problems with the battery during Wi-Fi operation. I can assume that the bad contact between the battery and the MP has arisen and disappeared. Use while it works. If it starts up again, pull the battery a couple of times. Good luck.
