CMOS battery of my computer motherboard dead! what happens ?

From past one week i had hard time configuring my system time and bios settings every time i switched On or reboot the system why? my computer motherboard battery was dead and i had no time to replace it with new one and i never changed it since i bought my computer from past 6 years.

I bet you folks didn't even know your PC had a battery, ever though what keeps your computer time and date up-to-date even if your computer is not turned on or unplugged even for weeks together? below is the video on how to replace your CMOS battery of your computer.



below are few things that kept annoying this week whenever i turned on my system:

1. Bios Setting screen and slow bootup: First of all the computer was going to bios settings whenever i switched on the system, every time i used to select default settings a three keystrokes of annoying process.

2. Change Date and Time: My thunderbird / Outlook and other applications and even some websites was showing security exception and was not loggin in due to expired or invalid certificate error because of date mismatch so every time i used configure date and time

3. Application Freeze: Weridly my firefox was getting freezed for few minutes before it was working again normally and also sometimes internet was not working for a while until i changed the date and time.

But all the above symptoms vanished instantly after replacing the CMOS battery and rebooting the system did you faced any other weird issue due to Dead cmos battery then do share with us
