If your computer started sounding like a cricket chirping, it usually means something bad has happened. Typically, it means that the battery or the UPS that your computer is using to get its power or to protect it from power surges has a failed battery.
So, if you ever hear your computer chirping like a cricket or your battery chirping like a cricket, that means you need to call in somebody to take a look and test your battery and just make sure that your UPS is still functioning. Perhaps, it needs to be replaced or perhaps it just may need a new battery installed in the UPS.
So, listen if a cricket is chirping in your computer closet and be aware that that does mean something.
Thanks for listening. Have a good day!
