• Replacing the battery on the motherboard. Battery on the motherboard. Why is it needed?

    Today we’ll look at the topic How to determine if the BIOS battery is dead. Let's begin.

    It's hard to imagine, but running out of one small battery can seriously disrupt your computer's performance. When BIOS battery runs out, the computer begins to crash and glitch, and then stops turning on altogether. To prevent this, it is necessary to notice all the symptoms of a dead battery in time and promptly replace it.

    1. The surest sign that the battery needs to be changed is a constant failure of the time and date in your operating system. This happens because the BIOS is responsible for the time and date on the PC. And if the necessary recharge in the form of a battery is depleted, it ceases to correctly calculate the time and date and resets them to the original parameters the next time it is turned on.
    2. The settings began to change to standard. Even if you have never entered the BIOS settings, you can easily notice this - when you boot your computer, an inscription will begin to appear on the screen containing the phrase “ CMOS checksum error", and a proposal to reconfigure your BIOS.
    3. The computer begins to seriously slow down, restart spontaneously or even turn off for no reason, and stops loading any applications or drivers.
    4. Some computers have a battery sensor on the motherboard. If it starts to sit down, the sensor warns the user about this when the PC is turned on.
    5. The computer stops turning on altogether, that is, it does not respond in any way to pressing the power button.

    Remember that the third and fifth symptoms separately may not relate to a dead BIOS battery. However, it is better to start checking with it.

    Helpful Hint: If you have a multimeter or voltmeter, you can check the voltage on your battery. To do this, remove it from the motherboard, having first disconnected the PC from the power supply, and measure the voltage. If it is much less than 3 V, then it is time to change the battery.

    Where is the battery located and what does it look like?

    The BIOS battery is located on the motherboard, in a special connector. It is round, almost flat, with a diameter of several centimeters. Usually it’s easy to pick it up with something sharp and pull it out.

    Where to buy a BIOS battery

    Such batteries are widely sold in departments with batteries and accumulators, as well as in any computer store. You can ask CR2032 battery or, without bothering too much, a BIOS battery. They will definitely understand you.
    Price for one battery – from 20 to 60 rubles.

    How to replace the battery

    How to change the battery in a wristwatch? Do you need the help of a specialist?

    So where to start? As a rule, people are accustomed to turning to specialists. Of course, this is the simplest option. The craftsmen know very well about wristwatches. However, you can deal with this on your own. The main thing is to know which battery was installed by the manufacturer. By installing exactly the same one, you guarantee the mechanism a long service life. You need to look at the type of battery. The abbreviation SR indicates that the battery is silver-zinc. CR - lithium. These batteries are the most durable. Most often they are used by manufacturers.

    Knowing how to change the battery in your wristwatch yourself, you can avoid installing a cheap alkaline model, designated by the letters LR. Unfortunately, unscrupulous craftsmen sometimes do this. These batteries do not last long. In addition, they weakly hold tension in the mechanism. As a result, the clock starts to lag quite quickly.

    Removing the back cover

    Of course, models with batteries are very convenient. There is no need to start them. But the battery is not an eternal thing. That's why it has to be changed over time. There is absolutely nothing complicated in this procedure.

    So how to change the battery in a wristwatch? It all starts with removing the back cover. It can be pressed or screwed. In the first case, a special recess is provided on the lid. A small screwdriver is inserted there. The lid is carefully lifted and removed. At this moment, the main thing is to hold the watch tightly.

    If there are several recesses in a circle on the back cover, you need to unscrew it. The easiest way to do this is with a caliper. The tool is inserted into two recesses, and the cover, turning counterclockwise, is carefully removed.

    Changing the battery

    The battery is removed using small tweezers, and a new one is inserted in its place. The main thing is that it is of the same design and specification as the old one.

    When installing the battery, do not handle it by hand. It is best to use the same tweezers for this. After installation, you need to check if the clock is running. Only after this the lid returns to its place. In a word, nothing complicated.

    Put the cover in place

    So, the final stage. If the cap is screw-on, it must be screwed using a caliper. Do not forget also that if a gasket was installed in the watch, you need to check whether it has become unusable. Otherwise, it also needs to be replaced. If you can’t find the exact same gasket, you can use a little sealant by applying it to the threaded part.

    The pressed cover is placed back on the watch on a flat surface. It is imperative to ensure that the groove corresponds to the axis of the wheel for changing the position of the arrows. After this, take a small flat object (preferably wooden), place it on the lid and gently press it on top. It should fall into place without any problems.

    Thus, knowing all the nuances of how to change the battery in a wristwatch (Casio, Oreintex or any other company), you can easily cope with this task. And, most importantly, you will do it quickly and correctly.

    Be careful

    It is only important not to forget about accuracy. If you damage the mechanism, you may not be able to “save” your watch. For example, when removing the cover, lift it very carefully. The watch must be firmly fixed, and the instrument must be pressed accurately and firmly. By the way, these measures are also necessary in order not to get hurt.

    When changing batteries, remove and insert them as carefully as possible. Tweezers should not touch important elements. In a word, caution is needed in everything.

    When closing the lid, carefully check the watch for leaks. If, when pressed with your finger, it still does not close, use, for example, a wooden mallet used for crushing berries, potatoes, etc. This way you can press on the entire surface at once. Eventually the matter will be completed.

    However, if you are still not confident in your abilities, you can always easily find a place where you can change the battery in your wristwatch quickly and without problems. Conscientious good craftsmen will definitely be found in every city.

    Instructions

    So, if you notice the first alarming demise of your system battery, don't put it off. We will need tweezers and a Phillips. First of all, turn off the power, disconnect the wires, mice and peripheral devices. Unscrew the two side screws and disconnect the monitor cable from the connector. If you are disassembling a computer for the first time, then carefully look and remember where each of the wires was connected. After this, you can begin opening the system unit.
