Translations:Yes, you can fix your laptop!/58/en
All laptops contain a small backup battery, often (for historical reasons) erroneously called the CMOS battery. This keeps the clock running when neither mains power nor a main battery are present. (Removing this battery will not reset the BIOS settings and BIOS password as sometimes thought. These have been held in flash memory similar to a memory stick in all computers since about the 1990's.)
