k_nitin_r 8 Report post Posted May 7, 2012 In laptops, the computer's date and time can be maintained by the regular laptop battery thus eliminating the need for a CMOS battery. The laptop only needs a capacitor for temporarily keeping the state of the clock when the laptop battery is being swapped. There may be cases when the computer's date and time doesn't change after the computer shuts down and the same date and time can be observed when the computer is turned on. This can be associated with a BIOS or motherboard problem rather than a problem with the battery, though it cannot be conclusively determined with a diagnosis that can be applied to all motherboards because vendors build their products differently.

Windows sets synchronization to occur weekly, but if you purchased a computer with Windows XP installed, your computer manufacturer may have set it to occur more often.* An Internet time server updates the date set by your computer as well as the time.* The Update Now button is not available unless the Automatically synchronize with an Internet time server check box is selected.Best regardsVicky Milza Share this post Link to post Share on other sites
