The motherboard time is not allowed to do

The reason for the motherboard time is not allowed and resolved:

⒈ computer time is not allowed for roughly 2 reasons, one is the computer virus, computer time by malicious software modification caused some software is not available.

⒉) There is a problem with the CMOS battery failure on the computer motherboard.

Careful friends have found that, even if the computer is turned off, inside the time will not be chaotic, until the next boot time is still accurate. So why is this? In fact, the reason is very simple, mainly the computer motherboard has a smos battery, its main function is to keep the computer internal clock power and to save the installed motherboard BIOS information, the motherboard on the CMOS battery as shown in the following figure:

Computer time is not allowed to solve the solution:

The above for you to introduce the time is not allowed, the wrong reason, then the time is not allowed or wrong solution is very simple. Mainly in the following 3 areas to solve.

1 The first rejection of virus interference, resulting in time damage

We can use the current mainstream antivirus 360 antivirus to the computer for a comprehensive scan, to see whether the computer virus, computer time is malicious changes, if there is anti-virus, we will correct the time back to solve the problem.

2 the computer motherboard in the CMOS battery aging, resulting in low internal storage computer

The CMOS battery on the motherboard is a rechargeable battery, but if the computer is used for many years, resulting in aging of the battery, can not store too much electricity, so the storage power after shutdown is very easy to run out, resulting in the wrong time.

The solution to this problem is mainly 2, preferably a new battery, the best replacement. But you can also do this, after the computer shutdown, do not unplug the power plug on the host, can also solve such problems, because the computer and power connected, the computer will always have standby voltage inside the motherboard internal clock to use, but this situation is susceptible to thunder, may damage the computer, so it is recommended to replace a battery.

Secondly:

First of all need to consider two aspects of the problem, the first is if your computer has been used for several years, the computer time to return to the next boot time and back, then you can consider the motherboard on the battery is dead, to determine the battery has no electricity method as follows.

2 first set the computer wrong time back, and then restart the computer, in the process of restart has been pressed delete can enter the BIOS settings, select Standardcomsfeatures, you can see the system time, if it is not correct, and then through the arrow keys selected time options and set, Then press F10 to save the exit. There are two kinds of judgments, if the time in the BIOS is not correct, then the battery reason. If the time is correct, then save to quit the startup computer is not correct, that is tampered with, tamper with the solution below are introduced.

3 can also be other computer batteries and this switch, if the time is not allowed, then it is not a battery problem.
