Hello everybody, I have a problem with my Ideapad, an annoying sound (critical low battery sound) wich is double beep loud sound, start happen when I was installing drivers, I installed the ThinkVantage and the Lenovo Power Management Driver, after that my laptop does that annoying sound every 5 seconds, since I power up the laptop every 5 seconds the laptop beeps and freezes, I bought another battery thinking it would fix the problem but nothing! I bought it because when I unplug the battery and use the laptop just with the AC power everything work perfect! Also when the battery goes exactly 20% or lowest the beeps/freezes goes await! Anybody know about this problem? Thank you in advance!!
Tried updating BIOS, fresh install of windows, discharge the battery, nothing seem to help, the only way the laptop don't do the beeps/freezes is when the battery is unplugged and the AC is connected, and when the battery is below 20% I don't know why!
