A CMOS battery--short for complementary metal oxide semiconductor--is necessary to retain your computer's hardware settings. Symptoms of a dying CMOS battery include system warnings, lost time settings, and sometimes even unexpected shutdowns. Once you've recognized the symptoms, you can check the battery itself.
A non-governmental organization (NGO) is a citizen-based association that operates independently of government, usually to deliver resources or serve some social or political purpose.
NGOs are difficult to define, and the term 'NGO' is not always used consistently. In some countries the term NGO is applied to an organization that in another country would be called an NPO (nonprofit organization), and vice versa.
