Cmos/Bios Problem (Date & Time Issue)

If you own a Windows Computer (PC) that always loses its time/date/year settings, then read this tutorial to fix the issue. If your PC doesn't keep clock settings after shutdown it, then probably the CMOS battery is dead. The CMOS battery is an internal battery on your motherboard that provides power on the CMOS (Complementary Metal Oxide-Semiconductor) chip. The CMOS chip, also known as "BIOS" chip, is a little amount of memory which stores information about your system configuration.

Windows time is wrong or clock falls behind is an issue faced most in windows 7 and windows 10 operating systems. Even though you try to set the correct time, it will be showing the incorrect one once you restart the PC. Windows clock is located at the bottom right corner of the screen. When you click on them you could normally see the clock along with the calendar.

Time shown on the clock is set either manually or by synchronizing automatically with the internet clock. It has the tendency to go wrong mostly due to hardware errors. When this happens certain web pages may fail to load. Therefore the user has to take immediate measures to make it right.

Fast Solution on Motherboard :

If you set your motherboard configuration with default setting at that time it will be probably displayed at startup on your PC screen like this.

Now enter inter the bios setting by using hot key like F2 or other key which is given instruction on your screen. Now the screen will display like this...

Fix the time by tying from the keyboard on the same format of H:M:S (Hour:Minutes:Second) and to fix for date DD/MM/YY (Date/Month/Year) & use hot Key F10 and Yes. After it will be restart  automatically and solved. 

If not solved please follow these 5 ways 

Method 1. Replace CMOS Battery.

The most commonly reason that your computer loses the Time settings, is a damaged CMOS battery, especially if the date resets to a date like 1/1/2009 and with time 00.00.00.

To find out if the CMOS battery is off, enter BIOS setup and set the current Date, Time and Year. Then "Save and Exit" from BIOS settings and then power off your computer. Disconnect any power source from your computer and remove the battery also, if you own a laptop computer. Leave your PC off for 2-3 hours and then power on it again. If the time settings are wrong then probably the CMOS battery is dead.

To replace the CMOS battery:

1. Turn Off your computer.

2. Open your computer's case.

3. Find out where the CMOS battery sits on motherboard. If you cannot find where the CMOS battery sits on motherboard, then read the motherboard's manual.

  

4. Remove the battery from its place. *

* Note: In many conditions you have to push ahead the CMOS Battery release lever to release the battery first.

5. Replace the battery* with a new one.

* Common types CMOS batteries.

Power On your system and then set the time settings in motherboard if displayed in Startup black screen and after that adjust date & time in control panel.

Method 2. Check CMOS Battery holder contacts.

The rarest cause that your PC loses time, is that the contacts in the battery compartment have become loose or broken. So, take the CMOS battery apart and check the CMOS battery contacts. If the CMOS battery clips are not broken, then may have loosened (may not be making contact). At this case, try to gently pull the contacts out or tighten, depending on the case. Put the battery back and power on your computer.

Method 3. Set your current Time Zone with right real time.

If the Time is displayed on Windows doesn't match the current time, then probably you haven't set your current Time Zone on Windows. The Time Zone is used by Windows to synchronize the Time by using an Internet Time Server. If the time zone is wrong then your computer, after restart, resets the time for the specified time zone

To Set the Time Zone.

1. Right click at in the system clock at the taskbar and select Adjust Date/Time.

2. Set the your current "Time Zone" *

* Note: If you are using Windows 10, then set the "Set time zone automatically" option to OFF.

Method 4. Change Internet Time Server:

Windows can automatically synchronize its settings by connecting to the time servers on the internet. In fact it is the normal recommended way of providing the accurate time. Sometimes due to the problems in the network, Windows can lose its connection to the time servers. Because of this the clock may be displaying the inaccurate time.

Therefore you have to manually sync your computer with the internet time servers to display the accurate time. 

To change the Internet Time Server,

1. Go to the Search Bar

2. Type '' Control Panel ''

3. Select Clock and Region

4. Choose Date and Time

5. Head to the Internet Time tab

6. Press change settings
7. Ensure that the synchronize with an internet time server is selected

8. Choose time.nist.gov in the server

9. Press Update now and OK

Method 5. Check your Computer for Malware.

Another reason that WINDOWS losing the time settings, is a Malware infection. To ensure that your computer is virus/malware free and follow the steps. Please install the Malwarebytes to clean viruses, through https://www.malwarebytes.com.
