Clock loses time
Question : I've noticed the last few months that when I turn off my Windows 98
computer, my clock loses time. Can you give me an idea what the problem is?
Answer : Although it is not always the culprit, the small battery on your
computer's motherboard may be dying. This power cell, usually called the CMOS
battery (for complementary metal oxide semiconductor), keeps track of the time
for your computer.
When the battery begins to weaken, your computer may start losing time.
Check your manual for information on the battery's type and location; it's
usually possible to replace the CMOS battery yourself, or a computer
technician can do it for you.
Battery issues aside, Windows 98 has also had some timekeeping issues of
its own, as explained at support.microsoft.com/?kbid(EQUAL)189706.
