Trouble with battery "communication" in Inspiron 5437

Recently I've restored my laptop to it's fabric settings and had to reinstall the drivers.

After this my battery seems to work quite alone. When I want to restart the laptop, it only turns off (not "sending some signal to turn on again"); when it turn into stand by - like when I close it - doesn't want to "wake up" and I need to *** it off manually.

Since I've reinstalled the drivers right before that happens, it seems like a driver problem for me (that don't understand any of it).

Please, help me.
