How to turn on Wi-Fi on Lenovo laptops

How to enable WI-FI on Lenovo laptops? A topic that I am sure will interest most laptop owners from this manufacturer. I want to emphasize right away that all the information below is for the most part intended for all modern models from Lenovo. But, despite this, Owners of second-hand laptops can also get a lot of useful information in this article.

From the title and the first paragraph, you can easily understand that the article has a narrow focus, that is, specially prepared for users with Lenovo laptops. This is due to one case, when different users brought me three laptops from Lenovo, asking me to see why Wi-Fi does not work.

This, of course, was not in one day, but every other day so for sure. In general, along the way, I found several interesting chips due to which Wi-fi may NOT work on Lenovo or will turn on only after performing certain actions.

Below I present information on how to enable Wi-Fi on Lenovo laptops in various situations, based on my personal experience when working and setting up computers from this manufacturer.

What to do if Wi-Fi does not work on Lenovo laptops

Of course, I understand that there are a lot of situations and reasons due to which the wireless network may NOT work. But, if you are one hundred percent sure that everything is ok with the router, then for sure the cause of the malfunction is hidden, unrelated, in the laptop.

Therefore, I will describe several main points on turning on the network adapter, after completing which you will either get the Internet working, or you will be able to move on based on the data received, for example, started checking the network settings.

Enabling the wireless adapter

The very first thing I recommend doing. This is to check if the network adapter is enabled.

  • Open the “Run” Dialog Box And insert the “ncpa.Cpl” command there, run it by pressing the “Enter” key;
  • Among the appeared network adapters, we find “Wireless Connection” And by clicking on it, we open the context menu;
  • Next, we find the term “Enable” And click on it with the mouse.
  • If instead of “Enable”, “Disable” is displayed, This means the wireless connection is enabled, so you can proceed to the next recommendation.

Checking the installed driver

Mandatory before further configuration, check if you have installed the driver for the Wi-Fi adapter.

  • Again, using “WinR” AND the command “devmgmt.Msc”, it gets to the device manager;
  • We open “Network adapters” from the list of available devices, And we find there the device responsible for Wi-Fi, usually the word “Wireless” is added after its name (In a normal Ethernet connection)
  • If it is displayed with triangles or there is none at all, but some unidentified device is present, then you have obvious problems with the driver, which must be installed.

You can download the driver on the Lenovo website, in the support section. The easiest way to find the required page, I killed the following phrase in a search engine: “Lenovo z50 driver“Substituting, of course, your model instead of the z50.

As for the installation, everything is SIMple and familiar there, we run Setup, wait a few seconds and restart the computer.

Enabling Wi-Fi on Lenovo with the Monitor Cover

In general, it so happened that the two laptops that came to me turned out to be the same model, namely Lenovo z50. The problem was that when the system was booted, the adapter did NOT turn on automatically, but when you pressed the key combination responsible for turning it on, the computer did NOT react in any way.

But, as soon as you close the monitor lid for a few seconds, then after opening the wireless adapter will turn on and start searching for available networks, which is pretty amazing.

In general, this trick worked on both laptops so that I recommend using at least this connection method for a start, for its further configuration.

The aLGorithm is SIMple, we closed the laptop lid, waited a few seconds, and opened it. Voila. the internet works. I know for sure that this option works on many laptop models from Lenovo.

Starting to automatically turn on the wireless adapter

Another option for enabling the adapter is the function keys on the keyboard, in which I mentioned above. Usually they are located on F1. F12 and are displayed in the form of various icons, while they are used only in combination with another “Fn” key.

READ  How to Fix the CPU Speed ​​on a Laptop

Just note right away that in newer models more and more manufacturers are swapping these buttons, as a result of which F1-F12 works only when you press “Fn”, but the functional ones, on the contrary, act as ordinary keys.

As it floated, on turning on the Wi-Fi adapter, I answer F5, F6, F7. In order to make it easier to determine the necessary button, you can look at the icon that is applied to it. These are usually Wi-Fi antennas or an airplane (Mode: airplane). For example, in the z50, I remember exactly that this is the F6 key and an airplane is depicted on it.

In general, after pressing, for example, on “FNF6” Or just “F6”, an icon should appear on the screen confirming that the network adapter has been turned on. Well, if nothing happens, then most likely you do not have the necessary software package installed, which uses these keys.

Installing Lenovo Energy Management

So, if your function keys do not work or only some of them work, then most likely you do not have Lenovo Energy Management installed.

The fact is that Wi-fi just may NOT work for you because the adapter is off, but you can turn it on only using the function keys, which in turn work only after you install this utility.

You can download it at the office. Lenovo website, for any version of Windows. After you install it, I recommend that you restart your computer and try using the adapter power key. If everything is OK, a small menu will appear on the screen, in which you can enable or disable Wi-Fi and bluetooth.

In our case, you need to set the value to the “on” position opposite the wireless network, respectively, by selecting it with the mouse. After that, the adapter should turn on and start looking for available wireless networks. In addition, now you do not have to manually start each time the operating system boots, since it will do this in automatic mode.

Also, if the necessary keys are NOT triggered, it would be advisable to check or even install the driver on the keyboard, downloaded it from the Lenovo support page.

Enabling Wi-Fi on Lenovo with a Button

In addition to the way to turn on the wireless adapter using the keyboard, on some models, there may be a separate special button or switch on the case, which is responsible exclusively for starting Wi-Fi on a laptop.

Usually it is located on one of the side faces of your laptop case or near the power button, special features by which you can recognize it all the same, it most likely displays an icon in the form of small antennas.

Energy saving mode

The power saving mode, which is enabled by default in the properties of the device, can also be a prerequisite for Incorrect operation of the wireless connection or its disconnection altogether. You can remove this function in the settings of the network adapter.

  • Opening “Run”, Copy there “ncpa.Cpl”.
  • Finding a wireless connection using a dialog box calling “properties”.
  • Next, the “Configure” button.
  • Go to the “Power Management” tab.
  • And there we uncheck the box that allows you to turn off the device to save energy.

After, do not forget to restart the laptop and check if something worked out or not.

Is the WI-FI adapter connected to the motherboard

Well, and finally, if nothing helped you, I can recommend checking whether the antennas are connected to the adapter directly on the motherboard itself.

I once had such a case that for some reason wi-fi did not work on a completely new laptop, while the drivers were installed, and the device was turned on. But He did not see more than one network, except for those cases when its distribution was carried out using a smartphone. Ito, he connected to it, but there was still no Internet access.

After trying everything, I decided to check if everything is fine with the connection under the cover by unscrewing it. As it turned out, the antennas were SIMply not connected to the adapter itself, although the laptop was new, there is a chance, of course, that they disappeared, or they SIMply forgot to connect.

In general, after I connected them. Everything fell into place and Wi-Fi started working normally.

Here are some of the things that, in my practice, helped me to turn on Wi-Fi on Lenovo laptops, maybe something will be useful for you. In general, as always, I await your comments and wish you good luck in setting up your computers.

A SIMple method for cleaning a laptop

In the event that NOT more than 1 year has passed since the purchase of the laptop, you can get rid of the dust without disassembling the case. All the user needs is to find an air outlet in the form of a grill, which in most cases is located on one of the sides of the laptop or behind.

To carry out the procedure, you need to resort to the services of a hairdryer or vacuum cleaner in blow mode. If you do not have one of THESE household appliances at hand, then you can get rid of the dust by blowing hard on the grate. The rising cloud of dust will indicate its release. But this method of cleaning will allow you to extend the life of the laptop by no more than 1-2 months, and is absolutely ineffective when cleaning from dust was carried out for a very long time.

The cost of cleaning a laptop from dust

Today the market has a huge number of companies and services that are ready to provide this service to every user. But it is worth remembering that due to the large amount of repair work, cleaning the laptop from dust may not be done as quickly as you would like. In this situation, it is worth doing the work on your own and in addition to time, you will also save money, which would have been spent on paying for the work.

But if you DO NOT want to take risks and think that this work should be performed only by specialists, then you can find a service that will clean your laptop in any city. Average and directly depends on the amount of work and the time for disassembling the device.

How to clean your laptop from dust

Anyone who owns a laptop will sooner or later witness the processor overheating due to the fact that the fan is no longer able to cope with the large volume of dust entering the device. As a result, the efficiency of the laptop is lost, up to and including its failure. If you clean it in a timely manner, you can reduce the temperature of the processor and other laptop components by 15-20 degrees.

Preparatory step and cleaning tools

We strongly recommend that before you start this procedure, refer to the instructions for your laptop, which will help you clearly determine the location of the cooling system. To clean, you will need to stock up on a clean cloth, as well as a Phillips screwdriver and a portable vacuum cleaner. If you do not have such equipment, then you can use a hair dryer or a can of compressed air. In addition, you will need silicone grease or machine oil to process the fan assemblies.

Categories: Computers, Reviews. Regular cleaning of the laptop

Experts recommend cleaning the laptop at intervals of 1-2 times a year. An important factor in how soon the device will need to be cleaned is the location of the cooling system and in a particular brand of laptop. So, for example, Asus, Acer, IBM, Samsung, HP and Lenovo need cleaning once a year, HP and Asus high-level devices. once every 2 years, but Apple products are ready to do without prophylaxis for at least 4 years.

Also, an important factor is the operating conditions. Of course, working with the device on the desktop and where cleaning is regularly carried out will lead to the fact that the cooling system can do without thorough cleaning of dust for a longer period.

Unfavorable factors that lead to an intense intake of dust into the laptop:

  • Owner’s smoking while working with a laptop;
  • The presence of pets in the house;
  • The presence of a transport road near your home or office;
  • Indoor renovations and other factors.

Lenovo Z500 laptop disassembly secrets

Today they asked me to fix the Lenovo Z500 laptop, which was slightly poured with tea (once again we make sure that you do not need to hamster without looking up from the screen). In general, it turned out that the hard drive has gone timeless into a better world. But I want to write NOT about this.

READ  Laptop no internet connection protected

Lenovo Z500 surprised me with its design. It will be rather difficult to disassemble it without breaking anything if you do not know a few tricks. To be honest, I have NOT fiddled with disassembly for a long time. Intrigued? Don’t worry, I’ll tell you everything now.

In terms of upgrade, this laptop is clearly not the best option for beginners, because in order to replace memory or hard drive (as in my case), you will have to disassemble it almost completely.

At first glance, only 5 screws hold the bottom cover of the laptop. No matter how it is! And here’s your first secret. 4 more screws are hidden under the rubber feet. The legs are NOT glued, they can be removed by slightly picking up from one edge (from which one can be seen in the photo). They are NOT completely removable, but remain on the rubber holder.

Don’t be in a hurry to rejoice. The cover is still NOT removable, as it is held by 5 more screws under the keyboard. And here we have the second feature of disassembly, and without knowing which it will be extremely difficult to dismantle the keyboard without damaging the decorative cover.

To remove the keyboard, there are two holes on the back of the laptop (from where the long screws were removed). Through these holes, using a narrow screwdriver or knitting needle, carefully push the keyboard out of the grooves. The upper part of the keyboard will come off and then we finally take it out. Take your time so as not to damage the train.

The keyboard is dismantled without the slightest scratch. It’s time to move on.

We almost opened the lid. there is one more small detail left. We take out the DVD-drive, under which the last 3 small screws are hidden. Congratulations. laptop cover removed!

Further, the disassembly process should NOT cause problems. Everything else, if you have even a little disassembly experience, should be familiar.

I note that the entire current U. and Z-series of Lenovo laptops are disassembled in a SIMilar way.

Symptoms indicating the need to clean the laptop from dust:

Overheating is the main sign that you cannot do without cleaning your laptop. With a large amount of accumulated dust, overheating is observed within a short time after turning on the device. Also, in problems with the operation of the cooling system, the internal fan reports increased noise.

Overheating has an extremely negative effect on the performance of the device, which affects the operation of the operating system and turns into problems with loading applications and programs. It is possible that the laptop will turn itself off spontaneously in order to protect itself.

Dismantling the laptop and clean from dust

Be sure to de-energize the laptop and the equipment connected to it, disconnect. Turn the device over and, by unscrewing the bolts, Remove the back cover. In doing so, try to make sure that the bolts are NOT lost. In most cases, you will NOT have to completely disassemble the laptop. So, the developers of a number of devices Asus, Acer, Rover have provided that access to cooling systems can be obtained by detaching the back cover. But if you are the owner of a Sony, HP and Samsung laptop, then you cannot do without a complete disassembly.

The favorite places for dust settling are the radiator (intercostal slots) and the cooler (blades).

After removing the fan, remove the dust from the blades with a napkin, but you need a vacuum cleaner to clean the radiator. In the fan, you will need to clean the impeller, for which you will have to get it out of the cooler.

Remember that the cleaned shaft needs to be treated with silicone grease or machine oil.

How to brighten the screen on a laptop? Easy and fast

In the process of working in new owners of mobile computers, the following question often arises: how to make the screen on a laptop brighter? If there is a problem with this on a stationary system unit (the monitor is installed separately and it must have buttons for control), then with such devices it is not so SIMple. Within the framework of this article, the most SIMple ways of solving this problem will be given. In most cases, they allow you to achieve the desired result. But if nothing worked, then you need to contact a specialized center for the repair of computers and laptops. Perhaps the answer lies in the fact that some component of the mobile PC has failed and needs to be replaced.

Card drivers

Now let’s figure out how to brighten the screen on a laptop using drivers on the card. Open the control panel for the graphics adapter by double-clicking the right mouse button on the right side of the taskbar on its logo. This could be a black and blue screen for Intel, a green icon for Nvidia, or a red label for AMD. Let us dwell on the first of them, since they can be found most often at the moment. In other manufacturers, the procedure is SIMilar. If we find something, we look at the documentation. After a double click, a menu will open. In it we select “Graphic characteristics”. Next, go to the “Display” section and find the item “Improving the quality of color” in it. A case will appear with a “Brightness” slider. By changing its position, we achieve the desired result. In the event that such a panel is available, then you need to install the driver from the disk, which came with the laptop. Another option where such software can be found is the official website of the graphics adapter manufacturer. In addition, the card drivers allow more flexible configuration of PC parameters. For example, using them you can reduce the resolution of the laptop screen or change its orientation.

Using the keyboard

The brightness of the screen on a laptop is changed by a special key combination. One of them is a functional one, located in the bottom row of keys between Win and Ctrl and the designation Fn is applied to it. It includes additional character layout. Among them, there are necessarily two keys, which bear the designation “sun”. On one of them, the arrow or triangle is turned up, and on the other. down. Accordingly, in the first case, we increase the brightness, and in the second, we decrease it. Now, to change the brightness, do the following. Clamp the function key and, together with it, the second one, on which the “sun” and the arrow (triangle) upwards are SIMultaneously located.

Extreme case

Have all the recommendations outlined earlier been followed, and the screen brightness on the laptop remains unchanged? In this case, you will have to contact the service center. As practice shows, most likely, something broke at the hardware level. This is especially true when the screen goes dark for no apparent reason. That is, nothing was installed, the settings were not adjusted. The reason can be anything: the train is frayed, the contact has moved away, or something else. In any case, finding the cause of the malfunction and fixing it at home is almost impossible. Therefore, you will have to contact the service center for help.

Energy plan

Another way to solve this problem is to change the power consumption. On a stationary computer, such an adjustment does not play such an important role as in this case, because it constantly works from the network. But for a laptop, this is critical. It can run on battery power, and when it goes into this mode, the minimum power plan is activated. One of its components is a decrease in screen brightness. To change the mode, perform the following manipulations. We go to “Start”, here we select “Control Panel”. In it you need to find “Power Supply”. A window with a list of available modes will open. We select a mode in them, which is called “With maximum performance”. After that, the brightness should immediately increase. This is another option for how to brighten the screen on a laptop.

Let’s sum up

This article provides a step-by-step answer on how to brighten the screen on a laptop. First, we use the keyboard shortcut. In most cases, this is a solution to the issue. Then we check for all the drivers on the PC and adjust the settings of this program for the graphics adapter. Another place where the answer to this question may be hiding is in the energy saving plan, which can be changed in the “Control Panel”. If everything is done, but the result is not achieved, then you need to contact the service center for help.
