How to Enable a Mouse for a Laptop


Although today's small, lightweight laptops allow for ergonomic typing and browsing, many users still prefer a handheld optical mouse for navigation. When you need to make precise movements with your cursor, such as while using image-editing software or drawing a diagram in Paint, the optical mouse is the preferred choice over the built-in touchpad. Whether you are using a wireless optical mouse or a USB mouse, enabling it as your primary navigational tool is easy to do. Verify that the mouse you are thinking of purchasing is compatible with your laptop model. Browse the mouse manufacturer's website or read the packaging to ensure that it will function with your computer. Plug the mouse's USB cable into the matching port on the side of your laptop. Restart your computer while the mouse is connected. Once the system has rebooted, the New Hardware Wizard will run and install the driver required for proper functioning of the mouse. Move your mouse a few times to confirm that the cursor responds. You may now use your optical mouse as well as your computer's touchpad for navigation. Install the required batteries in the wireless mouse. On most models, you can lift the top panel on the mouse to expose the battery compartment. AA batteries are typically used to power wireless mice. Plug the USB receiver bundled with the mouse into the port on the side of your computer. Press and hold the small button on the underside of the mouse and the button on the USB receiver simultaneously. Continue holding the buttons down until the tracking light on the underside of the mouse illuminates. Turn the mouse over and begin moving it to ensure that the cursor tracks properly.

Brush-furred mouse
The brush-furred mice, genus Lophuromys are a group of rodents found in sub-Saharan Africa. They are members of the subfamily Deomyinae, a group only identifiable through molecular analysis. Lophuromys is also known as the brush-furred rats, harsh-furred rats or coarse-haired mice.

In mouse oocytes
In many animal cells, centrioles and spindles keep nuclei centered within a cell for mitotic, meiotic, and other processes. Without such a centering mechanism, disease and death can result. While mouse oocytes do have centrioles, they play no role in nucleus positioning, yet, the nucleus of the oocyte maintains a central position. This is a result of cytoplasmic streaming. Microfilaments, independent of microtubules and myosin 2, form a mesh network throughout the cell. Nuclei, positioned in non-centered cell locations, have been demonstrated to migrate distances greater than 25 microns to the cell center. They will do this without going off course by more than 6 microns when the network is present. This network of microfilaments has organelles bound to it by the myosin Vb molecule. Cytoplasmic fluid is entrained by the motion of these organelles, however, no pattern of directionality is associated with the movement of the cytoplasm. In fact, the motion has been demonstrated to fulfill Brownian motion characteristics. For this reason, there is some debate as to whether this should be called cytoplasmic streaming. Nonetheless, directional movement of organelles does result from this situation. Since the cytoplasm fills the cell, it is geometrically arranged into the shape of a sphere. As the radius of a sphere increases, surface area increases. Further, the motion in any given direction is proportional to the surface area. So thinking of the cell as a series of concentric spheres, it is clear that spheres with larger radii produce a greater amount of movement than spheres with smaller radii. Thus, the movement toward the center is greater than the movement away from the center, and net movement pushing the nucleus towards a central cellular location exists. In other words, the random motion of the cytoplasmic particles create a net force toward the center of the cell. Additionally, the increased motion with the cytoplasm reduces cytoplasmic viscosity allowing the nucleus to move more easily within the cell. These two factors of the cytoplasmic streaming center the nucleus in the oocyte cell.

What is the BEST way to catch an elusive crafty mouse?
How to catch a crafty mouse? With gift certificates to a fabric store, of course. No, wait, that's what works for me. Here is a way that is both humane and involves that great passion of mice: peanut butter. The down side is that it requires a fair bit of patience and sitting still. Empty and clean out a tall-ish kitchen trash can, lay it on its side with a piece of paper smeared with peanut butter. You sit next to it, keeping very still and quiet. When the mouse comes to check out the peanut butter, you quickly tip the trash can back to an upright position. This traps the mouse at the bottom, and you can take it outside for a release into the wild

Hello everyone, I am Teacher Lin, and we meet again.



As for the Dujia brand, I have always liked their Fusion the most. The only shortcoming is that it does not have a backlight. However, as a classic 68-key arrangement, there is no problem in using it, and it is suitable for home use. The space occupied by the desktop is also very small, yes this is what I want.



Not long ago, Durga newly released the new Hi Keys keyboard. Compared with the Durga Fusion I am using now, it adds an F key area, cancels the wired setting, and adopts a dual wireless Bluetooth + 2.4G design. In order to make up for Fusion's regret, Hi keys also added a white backlight.



For some things such as full key without impact, adjustable support feet, 360-day long battery life, it is fully reflected in Hi Keys, and the classic plated switch is used in appearance. The biggest change is actually the keyboard, Hi Keys The keycaps of Keys adopt a newly designed square and round keyboard. For students who are used to OEM keycaps, it will take some time to get used to the feel of this keyboard.




Dujia Hi Keys wireless dual-mode keyboard adopts the classic 84 arrangement, retains the complete F key area, and also retains the direction keys. The main reason why I have not used the 61 arrangement is the lack of direction keys, so this keyboard is in The function is similar to the 87 arrangement, and the keypad part is relatively complete, which is suitable for the needs of most students.



In addition to a keyboard, there is also a white data cable in the package. The configuration is simple, but at least a shaft puller is provided, which is more convenient for DIY replacement keycaps behind me.



Durga Hi Keys retains a one-stage foot support, which is convenient for many students to adjust the height of the keyboard when using it. Although it is not a two-stage foot support, it is still sufficient.



The 2.4G receiver of Duga Hi Keys adopts a hidden design and is placed on the back of the keyboard. At the same time, it adopts a storage compartment design with magnetic suction. If you use Bluetooth, you can directly ignore the receiver.



The switch button of Dujia Hi Keys adopts a toggle design. After it is turned on, the toggle switch has a backlight display, which looks very interesting and interesting.



The wireless switch of Durga Hi Keys is designed in the style of a knob, which supports 2.4G, Bluetooth 1, and Bluetooth 2. Durga Hi Keys supports a maximum of three wireless devices. If you have a desktop, notebook, or tablet, it can be a perfect match.




Duga Hi Keys does not adopt the mainstream RGB backlight design, but a monochromatic white backlight design, but the backlight still has 8 lighting effects, which can also be turned off.



There are two types of switches for Duga Hi Keys, which are the paragraph tea switch and the mute red switch. Since typing is the main requirement for me, the choice of the red switch is also determined by my own habits. Those who are used to the paragraph feel can choose tea. axis.




I think the biggest change of Dujia Hi Keys this time should be regarded as the keycap. The keycap of Dujia Hi Keys adopts a newly designed rounded square keycap. The keycaps you are used to are also very convenient.




Durga Hi Keys provides two color schemes: dark blue and silver white, and silver white is more clean and tidy. The designer has added a lot of careful thought to the font design of Durga Hi Keys. The ESC button, the space bar and the two characters FJ of Dujia Hi Keys have been embellished with some contrasting colors, which makes the keyboard look a lot more fun.



The overall design of Dujia Hi Keys is not a square design, and the edges are designed with radians, so the overall feeling is more round. Probably fat people are cuter, and the appearance design of Dujia Hi Keys is also very cute.



Most of the time, the biggest trouble we have when using wireless keyboards is the battery life. We don’t know when the battery will run out. Wouldn’t it be very distressing if it doesn’t support wireless, and Dujia Hi Keys further reduces power consumption while ensuring the stable use of the keyboard, comprehensively The battery life is improved, and it supports 360 days of battery life when the backlight is turned off. You don’t have to worry about proper daily use, and you can use it while charging.



According to the official data, it can last for 360 days with the lights off in Bluetooth mode and 200 days in 2.4G mode with the ambient lights off. Is it very powerful.




Although the backlight of Durga Hi Keys is slightly monotonous in white, the effect is still good. Use the built-in shortcut keys to easily switch the backlight display effect and brightness, and the lighting effect speed of the ambient light can also be adjusted.



This is my current desktop configuration, isn't it cool, the keyboard with white backlight is indeed a lot of value-added. The design of the silent red switch is also suitable for me to code at home at night, and it will not delay my family's rest.



With more and more customized keyboards, many brands are struggling with DIY, and some brands such as ZOMO are unique in customization, and many well-known IPs have also captured a lot of keyboard hobbies. heart of the reader. me too. The spirit of migrant workers. You know my thoughts best.



The sad frog expression of the MUR cat released by ZOMO perfectly interprets the mood of going to and from work every day. The Sad Frog is another addition to the series of weird keycaps. This series includes four keycaps: Strange Cat, Sad Frog, F5 Cracked, and Phone Bug.



Changing a keycap can change a mood, making your keyboard unique, and life and work are not just fun. Although the epidemic has dissipated, we need to be careful to protect ourselves. Take no harm.



My feeling about the keycaps is that if you are a little tired of a keyboard, or this is a plain white or black keyboard, then you can choose a set of keycaps you like in your bag, and you can make the keyboard a With a perfect transformation, the ugly duckling may turn into a white swan.




The original keycaps of Dujia Hi Keys are actually quite good, and the elegant feeling is still very attractive. I happen to have a set of ZOMO trap One Piece keycaps on hand, and I am going to change them to see what it feels like.




ZOMO fingertip cultural creation One Piece keycaps are designed with PBT technology, and the processing technology adopts two-color injection molding and thermal sublimation technology. 147 keys are perfectly suitable for the needs of 104, 108, 98, 87, 68 and other arrangements, and can basically be made large. A full set of needs.




Replacing keycaps is a relatively delicate task. The original keycaps need to be removed and replaced with new ones. It is recommended to store the replaced keycaps in a storage box.




If you are a One Piece fan, then you naturally know that "One day, I will gather a group of partners who will not lose to anyone, and find the world's number one treasure, and I will become One Piece." The dream of young people.





The ZOMO Fingertip One Piece keycap adopts a brand-new mold, and the side and front adopt a fully transparent design. The multi-color design creates different light effects, and the light can only leak from the front and side.





From the side and front of the keyboard, you can clearly see the shaft body of the keyboard. This is also the place where light is transmitted. After the lighting system is turned on, the entire keyboard will not be too dazzling.







In fact, the ZOMO Fingertip One Piece keycap has concentrated the advantages of the jelly keycap and the fully transparent keycap in the early years. It uses PBT material as the top design of the keycap, which combines the advantages of the two keycaps.



In fact, whether it is a keyboard, keycap, or shaft, you must choose a product you like to accompany you. If you don’t like the appearance, you can change a keycap to change your mood. If you get tired, change it back. Change it often. Always new.



It’s like Mr. Lin’s desktop is always changing, but it’s the ageless heart that has changed. I often comfort myself that being interested in new things is my youthful attitude, and I will share my encouragement with all of you.

Sometimes I use an ipad for office work, and typing by hand is easy to make mistakes, and the speed is also very slow, so I want to buy a Bluetooth keyboard that can be used with the ipad. Seeing that many people recommend Logitech's K580, I am very excited!


First of all, its appearance is very small, even if it is put in a schoolbag and taken out, there is no problem at all. There are white, pink, and black colors to choose from, and the texture is also very good. It's just that the mouse is a little small, but it's not a big problem for girls to use it.



It is a square button, which is the same as our usual computer buttons, so that it can accept the touch feeling faster when typing, and the size of a single button is similar to that of a computer keyboard. Don't worry about it being too small, it is not easy to type. And the size is very thin, so it will not be particularly heavy to hold.



Many people say that Bluetooth keyboards have the problem of delayed typing. This one has little impact, it can be said that there is almost no, so it is also handy to use. The K580 is slightly larger than the K380. I like to type faster, so it would be more appropriate to choose K580.


There is also a mobile phone stand design, which is convenient for typing while looking at the mobile phone. I really understand our mentality of playing mobile phones. The multi-screen switching keys are arranged, which is very friendly to those who play games. It is not too convenient to use the numeric keypad to type numbers for fat loss. In general, this is a good value for money Bluetooth keyboard, and there is a USB excuse to connect to the computer, which is simply a treasure.

When you enter the four words "mechanical keyboard" on a question-and-answer platform, you will find a lot of related recommendations about this product. Mechanical keyboards are no longer synonymous with "expensive" a few years ago, but have stepped into At the 100-yuan level, is a 100-yuan mechanical keyboard really easy to use? How much budget is suitable for a mechanical keyboard? I have experienced a lot recently. Here are some of my views on mechanical keyboards, as well as the Duga K620W currently in use. feel.



I don't know how much of your computer is allocated to the keyboard and mouse, maybe less than 5%. Everyone would rather spend more money on graphics cards, motherboards, monitors, etc., and then spend tens of hundreds of dollars. A thin film keyboard, I used to do the same, because you asked me to spend five or six hundred to buy a mechanical keyboard, I thought it was not worth it, until after entering the society, I bought a green axis mechanical keyboard for more than five hundred, I didn’t realize that the real feel experience is not at the same level. This keyboard has been with me for seven years. Because it is wired, I have been looking for a more suitable wireless Bluetooth keyboard recently.



The keyboard is actually the same as a mobile phone. I would rather spend five or six thousand to buy a mobile phone and use it for two or three years than to change to a one or two thousand mobile phones every year, because the experience is different and the preservation of value is different. of. The same is true for mechanical keyboards. A one-step keyboard may give you a completely different feeling. When configuring a computer, you can use about 10% of your budget to buy a keyboard and mouse, so that you can get a good experience.



If you don't know how to choose a mechanical keyboard, I think you don't go to see the recommendation, but to actually experience it, go to a physical store to touch and try it out to find the one that suits you. I used to use the green axis to type. I think the paragraph feeling of the green axis gives people a pleasant feeling. Every sound of the sound proves my sense of accomplishment in coding. Later, when I came into contact with the red axis, I found that the red axis seems to be more It is suitable for typing, and the feeling brought by the customized Kaihua red switch is straight up and down, which is also the basic feature of the linear switch, and the trigger is relatively light, so the typing speed is accelerated.




Why do I say Duga K620W is the ceiling of domestic mechanical keyboards? What I am most afraid of for all charging products is battery life. Whether it is toothbrushes, earphones, stereos, keyboards, or mice, once charging issues are involved, these commonly used products are just right for you. It is the most frustrating when it needs to be used but there is no power, especially the keyboard, a product that I use every day, the longer the battery life, the better the experience for me. So I really like the 360-day long battery life of Dujia K620W.




In addition, it is not difficult to find that the products launched by Dujia in the past two years are very good in terms of appearance and hand experience. As a representative of domestic mechanical keyboards, its design details and the choice of shafts have brought consumers a lot of attention. All extreme experiences. From the appearance point of view, the Dujia K620w white light version still adopts a very classic double-layered design, which will not be overly exaggerated, but it does not lose its temperament and experience. The three colors of white, dark blue, and blue-gray have a very good texture when superimposed, and the functional divisions are clear at a glance. Not only is it convenient to operate, but it is also very good in terms of visual perception.




Durga K620W reduces the width of the top and wraps it with black material to further enhance the texture. At the bottom of the keyboard, there are no bells and whistles either. That is, the anti-slip pads at the four corners and the two-stage corner braces are not only non-slip but also convenient for users to adjust the overall height of the keyboard. The 2.4G signal transmitter storage compartment of the K620W is placed next to the corner brace on the right side, and the transmitter body can be seen as long as the storage cover is opened.



On the top left side of the fuselage, we can see a power switch and a USB Type-C data interface. In terms of connection methods, Dujia K620W supports three connection solutions: wired, wireless 2.4G and Bluetooth 5.0.



What kind of keyboard is easy to use? Don't look at the so-called ergonomically designed odd-shaped keyboards. The real and easy-to-use keyboards are actually traditional layouts. The traditional square design requires the fingertips to be placed on the keyboard for complete contact, and the concave surface is better. fit rather than other styles designed for good looks. In addition, the height of the keycap is designed according to R1~R4 or R5 to make the gradient more natural, so that you will feel comfortable when you put your hand on it, and the accidental touch will be greatly reduced. A good mechanical keyboard should look like a curved surface from the side, and Duga K620W basically meets the requirements.



I don’t like fancy things very much, so some mechanical keyboards with backlights have RGB lighting effects. In my opinion, it is the light pollution of marquees. Instead, the white backlight of Dujia is just right in my opinion, although There is only one color, but there are multiple modes: constant light mode, rotation mode, wave mode, breathing mode, starry mode, response mode, laser mode, ripple mode, etc.





Going back to the matching of the shaft body, Dujia K620W uses Kaihua’s customized red shaft, with a trigger stroke of 2.0±0.5mm and a trigger pressure of 45±10gf, and a full stroke of 4.0mm max, so the overall feeling is obviously better than mine when using it. The green switch in the hand is easier to trigger, and the Durga K620W adds silicone pads, sound-absorbing cotton, etc. to the structure, plus a thick base, so it won't feel empty during the knocking process when using it.




It supports wired, wireless 2.4G and Bluetooth 5.0. In the case of wireless, it supports three groups of devices to be connected at the same time. Switching between different devices can be operated directly by combining hotkeys. And it supports both win/OS systems, which is friendly to Apple users.



Game lovers know that the setting of keyboard shortcuts is more conducive to the development of games to a certain extent. For Durga K620W, there is still room for playability. With DURGOD Zeus Engine driver software, And all modes support full key no punch technology, macro key function and onboard storage function.




Dujia should be the first echelon of domestic mechanical keyboards. In short, from the few keyboards I have used recently, Dujia K620W is definitely my heart in terms of feel, appearance, keyboard texture and functionality. Well, especially the long battery life, which is really good for a lazy person like me. Personally, I suggest that when buying a mechanical keyboard, first determine what you are mainly using it for, and then confirm the choice of the switch body accordingly. As for the brand, you really don’t need to consider those products that cost more than a hundred yuan. Look for the big names and invest a little more budget. You get what you pay for.
