• Replacing the battery on the motherboard. Replacing the battery on the motherboard is easy, just remember to recycle it

    Japanese quartz or Swiss mechanics? This question has been haunting the minds of millions of future watch owners for several years. Undoubtedly, with the advent of the Apple Watch and smart wearable devices from third-party developers, sales of classic wristwatches have decreased significantly, as Swiss manufacturers have already reported more than once. Both smart devices and multifunctional quartz are “dependent” on electricity, or more precisely on a small power supply. But if “smart” devices need to be charged almost every day, then a regular battery in a wristwatch lasts for a couple of years. We will tell you in this article how to change the battery in a wristwatch without affecting the functionality of the device.

    Sooner or later, every quartz owner will think about the above question, since in our world nothing lasts forever. Of course, you can go to a watch shop, but it’s much easier to buy a battery in a store and replace it yourself at home. When purchasing, you should not save, as a low-quality battery can damage the watch mechanism. A high-quality power supply, as a rule, ensures the operation of a wristwatch for 2-5 years.

    To replace the power supply in a watch, you must first remove the back cover. Typically, there are several ways to attach the cover to the body. It can be either pressed or tightened using small screws. If there are screws at the edges of the cover, unscrew them using a small clock screwdriver with the appropriate profile. Moreover, when unscrewing, do not rush, because the screws are quite fragile. If there are no screws on the back cover, then find a small recess, pick it up with a screwdriver or knife and pry off the cover.

    However, there are watches with a fastening in the form of a threaded ring. In this case, there are small notches in a circle on the back cover. As a rule, such covers are unscrewed to the left.

    Replacing a watch battery will not cause any difficulties if you use the tools skillfully. After opening the back cover, carefully inspect the internal mechanics, note the location of the battery and its polarity, and then carefully remove the power element using non-metallic tweezers. It is important that the new battery matches the element being replaced in all respects (diameter, thickness, voltage), otherwise the watch may lose its functionality.

    After installing the power supply, make sure the watch is working properly and carefully screw or press in the cover. At the same time, try not to touch the battery with your fingers. If the back of your watch is marked "Water Resistant", be careful not to damage the seal when closing the cover.

    The new generation of quartz uses “End Of Life” technology. The low battery indicator (EOL) is activated when the battery is running low. If on a watch equipped with an EOL system, the second hand stops jumping every second and starts counting down 4 seconds, then this indicates that it is time to change the battery on the watch.

    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.

    • replacing the battery on the motherboard

    On the motherboard, even an inexperienced user can easily find a CR-2032 battery, usually located at the bottom of the board, next to the PCI slots. If yours starts reporting the error CMOS battery failed, and the clock in the operating system constantly gets lost, then it’s time to change the battery.

    You will need

    • - computer system unit;
    • - screwdriver;
    • - vacuum cleaner;
    • - small brush.

    Instructions

    Remove the side cover of the system unit, allowing access to the motherboard. If the inside of your computer is covered in dust, take a brush and vacuum cleaner and carefully clean all the circuit boards. Without this procedure, you cannot begin to replace the battery. It is also worth considering the fact that the computer system unit contains small parts, so you need to carefully clean all the insides.

    If the motherboard is clean, move the cables and wires that are in the way (but do not disconnect them from the motherboard, otherwise you will not remember where they were later) to provide free access to the lower area of ​​the motherboard. The battery is attached to the motherboard using a light latch - carefully bend it with a screwdriver or your finger. The battery will pop out of the socket. Replace it with a new battery. Such batteries can be purchased at any store that sells small

    How to change the battery in a wristwatch Instructions

    Store website

    Battery-powered watches are convenient because they do not need to be wound and quartz watches are more accurate. The question arises, where and how to replace the battery. And replacement in a workshop will be quite expensive, except for our workshop IMchasov M. Savelovskaya, Sushchevsky Val no. 5 building 12, TC Savelovsky mobile, pavilion L150. Study our recommendations and replace the battery in your watch yourself, usually an SR626SW battery. But keep in mind that there are watches where you can open the back cover, but you will have to close it using a press.

    To replace the battery in your watch, the first step is to open the back cover of the watch. The cover can be screwed and pressed. Look carefully: if the cover is pressed in, then there is a recess on the watch case and the cover needs to be lifted either with a screwdriver or a knife. Take a small knife or small screwdriver, insert it into the recess and pry off the lid. The watch must be held firmly, and the pressure must be firmly and carefully so as not to break the watch and injure yourself.




    If the back cover of a wristwatch has special recesses along the case, about six to eight, then it can be unscrewed. Of the tools that a home craftsman might have, a caliper or a small rubber ball is best. Spread it to the width of the marks and tighten the bolt. Insert the caliper into the two recesses and unscrew the cap. You can also open the lid with a small rubber ball. Press the ball against the watch cover and begin to twist and the cover will unscrew. You need to unscrew it to the left.

    Even an inexperienced PC user can cope with replacing the battery on a computer motherboard. There is nothing complicated about this. You just need to follow the instructions and be careful. You also need to choose a battery for your motherboard. they differ in thickness.

    There can be 3 types of batteries in a computer, they differ only in thickness.

    • CR2032 (Is standard. Thickness 3.1 mm);
    • CR2025 (Thickness 2.4mm);
    • CR2016 (Thickness 1.6 mm).

    To find out what kind of battery you have, you need to take it out and look at what is written on it and buy the same one. Of course, you can install another one, but then it will hardly fit into the socket and there is a chance of breaking the holder or it will dangle and can disrupt the operation of the system. Therefore, it is better to install the same one that was installed.

    Finding the battery socket can usually be found on the lower right side of the motherboard. It is difficult not to find batteries, since such elements are no longer on the motherboard. And she looks like this:


    The first thing you need to do is turn off the computer and completely disconnect it from the outlet.

    To remove the battery, take tweezers, scissors, and a screwdriver and pry it off. Be careful not to let the tool jump off and damage the motherboard. Some motherboards have a special foot that, when pressed, will cause the battery to pop out of its socket.


    After replacing the battery, the first time you turn on the computer, your BIOS settings, date and time will be reset. Most likely you will see the following error on your monitor screen: CMOS checksum error — Defaults loaded

    You will be asked to choose whether to go to the BIOS settings or apply the default settings using the F1, F2, DELETE keys. By pressing F1 you will continue working with the default settings.

    To remove the battery from the motherboard, you need to press on a special metal leg that holds the battery in the socket. The battery is removed if you need to reset the BIOS settings or replace it.

    It's hard to imagine, but such a battery can affect the operation of the entire system. When the battery on the motherboard runs out, the computer begins to glitch, slow down, and then may not turn on at all. To avoid this situation, you need to know the signs of a dead battery on the motherboard and replace it as soon as possible.


    1.The most common symptom and the easiest to identify is a time and date failure. The BIOS is responsible for the time and date; it is actually powered by this battery when the computer is turned off. If the battery is low, the time and date are reset, which means the battery needs to be replaced.

    2. The second sign is that when you turn on the computer you see the inscription CMOS checksum error. This means that your BIOS settings have been reset. If you have not done this, then the battery is already running out and needs to be replaced with a new one.

    3. The next sign is that the computer begins to slow down, randomly reboot or turn off.

    4.Some motherboards have a battery charge sensor. If the battery is low, you will hear a squeaking sound when turned on. If previously there were no extraneous sounds when turning on, but recently they appeared, then there is a possibility that the battery is dead.

    5.And the last sign is when the computer does not respond to the power button. This can happen if you ignore the above signs. Another option was that the computer was not turned on for several years, but this option is unlikely.

    It is worth paying attention to points 3 and 5. Such signs may occur for other reasons, but the check should begin with the replacement of the battery.

    What is the battery voltage on the motherboard?

    The battery voltage on the motherboard is 3V. You can check the voltage with a multimeter or voltmeter. To do this, you need to remove the battery from the computer, first turning off and de-energizing the computer. If the voltage is much less than 3V, then such a battery should be replaced.

    In this case, it makes no difference who the battery manufacturer is, they all work the same. They will last from 2 to 5 years. It’s just that some users are calmer and they think that a battery for 500 rubles will work better than one for 50 rubles. But it is in this case that price does not play any role. There's no point in overpaying. On the Internet, prices vary from 30 rubles to 500. Personally, I bought for myself for 30 rubles.


    Probably, any user has paid attention to the fact that even after a sufficiently long disconnection from the network, the computer still retains basic information about the operation of the system, such as time, passwords and much more, and you can even completely unplug the power cord and deprive it of any energy sources, but the information will still be saved. However, few people know that for this effect, a specialized battery for the motherboard is installed in the computer.

    What is she?

    Today, not everyone knows what this device is. At the same time, it is immediately worth noting that, despite the prejudices of people who do not even know what a battery for a laptop or PC is, it is not a battery, but a battery. That is, the device has a certain shelf life, and the energy in it is only enough for a specific period of time, and it cannot be replenished in any way.

    What are they?

    The battery for the motherboard today is specialized manganese-dioxide lithium batteries of several types, which differ in energy capacity and also in height. The marking of the battery you use is a set of parameters, so this question is often asked in various stores if you suddenly want or need to buy a new device. Any battery for the motherboard should have a voltage of 2.75 to 3.3 V.

    Which is better to choose?

    In this case, there is no difference in which manufacturer you will get a battery for a laptop or for a PC, since they practically do not differ in quality, and in any case, the validity period of the purchased device will be from two to five years . However, as in other cases, here the purchase of a more expensive battery from a well-known brand has a calming effect on users, so they often prefer such equipment.

    Why is it needed?

    Unlike a number of modern electronic devices, the computer's date and time settings will not be lost even after the power is completely turned off. The motherboard battery allows the specialized program that is used to control this board to save all the basic data without losing it even if the power supply stops functioning.

    It is worth noting the fact that, among other things, the functionality that such a battery has also includes storing a certain amount of information located in the BIOS chip. It is for this reason that today there are quite often situations on the Internet when this device is simply called a “BIOS battery” (or something like that).

    The purpose of the “BIOS battery” is to maintain the functionality of the computer’s specialized CMOS memory, which, in turn, is used to store the computer’s basic configurations, including BIOS values, as well as the system timer. The volume of this memory is only 256 bytes, so it is difficult to even imagine how little memory is required to maintain its functionality.

    What is BIOS?

    The BIOS itself is a specialized program that is relatively small in scope, but is responsible for the most important settings of any modern computer. By using such a chip, the computer independently determines exactly how it will need to launch the workflow before the operating system is loaded. If the battery suddenly stops working, the system will immediately display a message that will provide complete information regarding the error that occurred when starting the machine, and in such a situation, the computer can only be started by pressing the F1 - Resume button.

    How do you know when you need to change the battery?

    The fact that the battery on the motherboard is dead can be judged by the following signs:

    • Continuously, after the next shutdown of the computer, the time and date are completely lost, or the time begins to lag significantly behind the current one.
    • When we try to open certain web resources, the browser constantly warns us that the certificates of these sites have long expired.
    • The antivirus program you installed constantly complains that it has outdated antivirus databases installed. If the utility is paid, a situation may occur where the license key is lost because it simply hasn’t expired yet.
    • Some programs completely refuse to launch.
    • Various messages are displayed on the screen indicating various errors.

    How to change the battery?

    Changing the battery on the motherboard of a laptop or PC is quite simple:

    • Initially, you need to restart your computer, then hold down the “Delete” key to enter your computer’s BIOS. It is worth noting that it is best to copy all your BIOS settings onto some piece of paper, because after you change the battery, the system settings will be completely reset.
    • Turn off the computer, and then additionally switch it to the “Off” position. switch on the power supply. Only then should the power cord be unplugged from the power outlet. It’s worth noting right away that it’s best not to start the next step right away, but initially wait at least a few minutes.
    • Now you can remove the side cover of your system unit and try to find the battery on the motherboard. It is installed alone and looks like a large silver coin, but to make it easier for you to search, initially try to look in the area of ​​​​the video card or under it.
    • Carefully remove the battery by pulling the latch to the side, then install the device you purchased in its place.
    • We close the side cover of the system unit (do not forget about the screws), and also connect power to it. Don’t forget that, most likely, you also turned off the power using the button on the power supply itself, so the switch should also be set to the “On” position.
    • Turn on the computer and hit the “Delete” key again. After the BIOS opens, you will need to set the current time and date in the settings, as well as all other information in accordance with the entries that you made earlier. After this, it is important to click “Exit&Save Changes” and agree to restart.

    That's it, replacing the battery on the motherboard is complete, you can use the computer again. In the vast majority of cases, such a procedure is required once every 3-5 years of operation of any modern computer.
