Why is time lost on the computer?

There are several reasons why time is wasted on the computer. However, the elimination of such a malfunction in most cases is quite possible for the average user, of course, if you know what to look for.

Independent power supply

Perhaps many will be surprised to learn that there is a battery on the motherboard. Its purpose is to save the user's BIOS settings and support the progress of the built-in electronic clock in the chip in the absence of external power. In fact, this is obvious: the clock can either start, or use some external source of energy. Thus, if time is constantly getting lost on the computer, it's time to change the battery to a new one.

Replacement

Find it on the motherboard will not be difficult: a brilliant disc the size of a five-kopeck coin will be noticed by everyone. All work must be carried out when the power cord of the computer is pulled out of the socket. Gently pulling the upper contact with a small screwdriver, you need to remove the CR 2032 battery. After that, it is useful to clean the contacts in the connector with an eraser, and "walk" through the new battery will not be superfluous. We recommend that you check the voltage of this power supply with a multimeter before installing the replacement - it must be at least 3 volts. After installing a new battery, you will need to re-configure the BIOS (for the input, you should often press the Del button immediately after turning it on). After that, that time is wasted on the computer, you can forget for several years.

Nuances

Although the vast majority of motherboards use a standard battery, some manufacturers went the other way. So, as a power source can act a sufficiently capacious capacitor. In addition, sometimes the battery is enclosed in a single unit, so you can not find it without a thorough inspection of the elements. However, there are no such cards.

Hardware Fault

In rare cases, even after replacing the battery, the user notices that time is wasted on the computer. In this case, it can be recommended to clean the contacts and the battery more thoroughly (at 3 V, even a thin film of fat on the metal can cause a significant voltage drop). Also it is worth making sure that the contacts have not been repaired, and their clamping has not decreased.

Time is wasted on the computer: Windows 7

As we indicated at the beginning of the article, the reasons for the malfunction may be different. For example, many users forget that if time is lost on the computer, it is entirely possible that the operating system and related programs are to blame. For example, if you set the time and date in Windows, they will be saved in the BIOS. From this it follows that if the time zone is set inaccurately and the background synchronization is on, then after each system boot the time on the computer will be set automatically according to the data coming from the server. In this case, any attempts to correct the time through the BIOS of the motherboard will fail insufficiently effective, since after the first boot of the system the clock will go down again. We recommend to disable synchronization altogether. This can be done via Start: Control Panel - Date and time setting - Time on the Internet.
