So tonight I boot up my computer and everything was normal, it was displaying the voltages as it usually does but the "VBAT" voltage was blank/blinking and it just sat there and wouldn't enter windows. I manually restarted the computer and everything was fine and my VBAT read 3.89 and went straight to windows.
Not sure if it matters but it was very cold in my room at that time. Is this something to worry about?
