Zyxel keenetic 4g instructions for use. It's done like this

One day, every laptop user experiences computer slowdown. The older the computer, the more often it “goes stupid” - this is not surprising. Increasingly complex software increases the system requirements for the computing capabilities of the device.

Laptop slows down, what should I do? Windows 7, like any other operating system also overgrown with errors, “tails” from deleted and reinstalled programs.

Where to start searching? The laptop is very slow, what should I do (Windows 7)? Let's look at some of the most common factors that influence data processing inhibition.

The most important symptom of electronic disease is old age

The diagnosis can sometimes be made independently, without the involvement of specialists. With the left mouse button, turn on “Start”, raise the cursor to the inscription “Computer”, click on the inscription with the right mouse button, lower the cursor to the inscription “properties”, click it. The window that opens in the “System” section will tell us about the main characteristics:

1. Score (numeric value of the Windows Experience Index).
2. Processor (manufacturer, type, name, clock speed of the main processor).
3. Installed memory (RAM) is a random access memory device.
4. System type (64 or 32 bit OC).

Left-click on the inscription “Windows Experience Index”, in the window that opens we read “Evaluate and increase the speed of your computer.” In this section, you can see which indicator has the lowest performance rating. Modern games and video processing products have high hardware requirements for hardware performance.

The performance index listed in the product description must match or be lower than the index of your PC. Otherwise, slowdowns and slowdowns will occur. Sometimes you can increase performance by installing more RAM (RAM), perhaps replacing the processor or video card, if the device design allows it. By replacing the hard drive with a solid-state drive, you can significantly speed up processor data transfer. In another case, you will have to use programs with fewer requirements, or replace the PC as hopelessly outdated.

Tight boundaries of unfavorable disk space

With the left mouse button, turn on “Start”, raise the cursor to the inscription “Computer”, click the inscription with the left mouse button. The disk space will be displayed in the window that opens. Blue color The stripes of the hard drive in use indicate normal capacity. Red color indicates a lack of free space and the need to free up part of the disk for further work.

With one click of the left button, select the desired disk. Then right-click to open the menu, and left-click “Properties”. Click “Disk Cleanup”, then “OK”. If the color of the strip remains red, then you need to delete some of the files or move them manually to another medium. In this case, it may well be cloud storage, another hard drive or other suitable storage medium.

If there is not enough space on the system disk itself, then Windows 7 will slow down very much.

Damage to system files

Going to the “Properties” menu, in the “Tools” tab, turn on “Run check”, then “Run”. Check the boxes - “Automatically correct system and other errors”, “Check and repair damaged sectors”.

Windows 7 will offer to check the system hard drive for failures the next time you start the PC. Enable “Scan Schedule”. The next time you turn on the laptop, the scan will be automatically enabled. The hard drive will be checked for errors.

File defragmentation technique

In the “Properties” menu, the “Defragmentation” tab allows you to use the operating system to place the necessary data on the hard drive in the most convenient way for Windows 7. To minimize the time spent finding the necessary information. In the tab that opens, you will see the status of the hard drive. After analysis, you may see Windows recommendations about the need to defragment. Defragmentation can take quite a long time, so it should be turned on on a schedule.

Page file and visual effects

What to do if your laptop slows down and freezes in Windows 7? To speed up your laptop, you can use the capabilities of the OS. Go to the “Start” - “My Computer” tabs, click “Properties”. The next inscription is “Advanced system parameters”, turn on “Performance”, “Options”. Then “Visual Effects” and “Ensure Best Performance”. With this mode of operation of Windows 7, the appearance of the interface will be significantly simplified; the windows will take on a very primitive appearance. This will relieve the RAM and slightly speed up the laptop.

In the same place, select the “Advanced” tab in the “Virtual Memory” section, go to “Change”, check the “Automatically select paging file size” checkbox or specify the size in accordance with the recommended one at the bottom of the window. The page file allows Windows to reserve part of the hard drive for storing the most frequently used information.

Viruses and Antiviruses

Very often the laptop slows down and freezes due to the presence of viruses. Therefore, you should use antivirus software to prevent periodic virus removal:

• Ad-Aware;
• Avast;
• Avira;
• Bitdefender;
• Comodo;
• Kaspersky;
• Panda;
• Qihoo 360 Total Security;
• Sophos Home;
• ZoneAlarm.

The antiviruses themselves also use resources, so because of them, the laptop may also slow down. Therefore, when choosing an antivirus, you need to take into account its system requirements. If you need to speed up your laptop, you can temporarily disable the antivirus.

Garbage in the registry

Only experienced specialists can professionally clean up the registry. For ordinary users, there are a number of utilities that allow you to do this with minimal risk. For example, "CCleaner". It is freely available on the product manufacturer’s website and you can download a trial version. After downloading and installing this utility, turn it on. The “Analyze” button activates the process of checking temporary and outdated files. “Cleaning” removes them. This operation must be performed several times to ensure complete removal of unnecessary files. It should be noted that CCleaner does not know what is important to you in your browser history and what is not, so when choosing files to delete, carefully review what you are deleting.

The “Register” button switches to the registry check mode. Turn on “Search for problems”. After finishing the search, click “Fix”. Next, the utility will offer to save backup copies of all changes made on your PC, you should agree. If the PC malfunctions after fixing the problems, you can restore the registry using a backup copy.

Programs and components

Sometimes the hard drive is cluttered with unnecessary programs; to remove them, we follow the inscriptions one by one. “Start” - “Control Panel” - “Small Icons” - “Programs and Features” - a list of all installed programs will open. Select unnecessary ones from the list, then delete them.

Autoload

In the search bar, enter “msconfig”, enable the detected utility, select the “Startup” tab in the window, select unnecessary programs in the list that appears and remove the “bird” in front of them. Then "Apply". Autoloading is only necessary to automatically enable the utilities that you really need. Some programs are automatically, independently registered in startup. RAM is constantly loaded, although there is no need for this. Therefore, by prohibiting them from turning on automatically, you will greatly facilitate the operation of the device.

Temperature violation

Causes of emergency temperature regime there may be many. If the main processor or video card overheats, performance will deteriorate significantly. This may have been caused by closed ventilation holes or a malfunction of the main components of the laptop. The AIDA 64 utility will help in identifying violations of the temperature regime of the main elements. Once you have identified the problem, it will be easier to make a decision on how to fix it. A correctly formulated query will help you find several useful answers on the Internet. You should not take at face value everything you find on the vast expanses of the World Wide Web.. Analyze several sources before making a conclusion.

Disabling system services in Windows 7

There are many myths about disabling Windows 7 system services. Often, various sources mention the need to disable unnecessary services to optimize the PC. Opening the “Services” tab, you will find that many services are either disabled or running in manual mode. Even if you disable all unnecessary services, you will not get a noticeable increase in performance. And if you mistakenly disable an important service, your PC may stop working or significantly degrade your experience.

Warning

These recommendations should not be followed by users unfamiliar with such processes. If you doubt your knowledge, contact well-established professionals. For general information, you can go through all the diagnostic points given in the article, make the necessary entries for yourself, without changing anything in the settings without uninstalling programs.

Quite often, computers with Windows 7 begin to slow down. Such a problem may not consist of any internal components at all; it can be solved by resorting to the use of certain methods for restoring the full functionality of the system and increasing its performance. Let's consider a number of basic actions:

• You should clean and defragment your hard drive.
• Remove unnecessary utilities, as well as other system junk.
• Make some visualization settings.
• Optimize the startup list.
• It is necessary to defragment the registry and sort its components.
• Do memory diagnostics.
• Disable Windows services.

1. The computer works slowly, the laptop slows down, what should I do? Windows 7 noticeably loses in its performance.

Any computer contains many outdated system and user files that can affect the speed of a PC or laptop. Defragmentation may also be required to optimize fragments scattered across the disk, which are necessary when reading a file with one or another software package. To achieve maximum efficiency when defragmenting, it is recommended to first clean your computer of all kinds of system debris, among which the following files are common:

• Remains of previously deleted applications.
• Temporary files.
• A variety of outdated shortcuts.

To avoid any problems when manually cleaning your PC, you can use free utilities:

• CCleaner. Represents a software package, created to clean your hard drive and optimize Windows performance.
• Defraggler. It is a fully functional tool for performing high-quality and correct defragmentation.

First of all, you need to open CCleaner and select a tool called cleanup. If the user wishes to leave the authorization intact in in social networks and other sites, you need to go to the cleaning parameters, uncheck the box next to Cookies and click “Analysis”. After the preliminary analysis, you need to press the “Cleaning” button and the application will remove the found garbage automatically.

It is worth noting that by opening the “Service” tab, you can go to the disk analysis item and select not only the system disk, but also all others. It is possible to include any type of file in the analysis, including multimedia.

After completing the above steps, you can launch Defraggler, and the launch should be done with administrator rights. In the complex window, you should select the hard drive required for defragmentation, then by right-clicking, select the “Disk Defragmentation” option in the context menu. To select multiple drives, just hold down the Ctrl button and select them. After automatically analyzing the marked disks, the utility will begin defragmentation. The program allows you to defragment individual files; to do this, you need to open the item with a list of files.

Some users prefer the standard defragmentation tool; to activate it, you need to do the following:

• Enter the Start menu.
• In the search bar parameters, enter the word “Defragmentation”.
• Launch standard remedy from the list of search results.

2. How to properly configure visual effects when Windows 7 is running slowly?

As you know, visual effects can seriously load the video card of a computer or laptop, thereby slowing down the Windows 7 interface. Any parameters related to the visualization and graphical interface of Windows 7 are located in the visual effects manager, you can get to it as follows:

• From the Start menu, select the search bar.
• Search for "Visual Effects".
• In the search results, select “Adjust system presentation and performance” and go to visual effects settings.

There is a more reliable way to open visual effects parameters:

• Go to Start, then Control Panel.
• Open the “System” item and launch the “Advanced Settings” section.
• In the settings window, find “Performance”.
• It is recommended to check the “Ensure maximum performance” option.
• Check the boxes for “Enable desktop composition,” “Use window and button display styles,” “Display thumbnails instead of icons,” and “Smooth out jagged screen fonts.”

3. Features of startup when restoring Windows 7 performance.

Circumstances may develop in such a way that, along with the startup of the Windows system, various software packages will automatically launch, most of which the user simply does not use. Startup settings affect the computer's RAM, so let's look at the basic steps required to remove certain programs from startup:

• Open CCleaner.
• Go to the "Tools" section and select the "Startup" option.
• The window located on the right side of the screen will contain a list of all utilities and applications that start simultaneously with the OS.
• You should select unnecessary programs and disable them, and then remove them from the startup list.

4. Method for defragmenting and cleaning the registry in Windows 7.

Being a large database responsible for storing all kinds of information about computer settings and parameters of software systems, a clogged system registry can lead to a significant decrease in operating speed. Let's look at how to optimize this registry:

• Launch CCleaner with administrator rights.
• Go to the “Registry” tab and press the “Search for Problems” button.
• After finishing the search, click “Fix”. If necessary, the utility offers to save backup copies.
• You should click on fix the noted problems and wait for this process to complete automatically.

Defragmentation of the registry should be done as follows:

• Launch the Defraggler software package.
• Activate the “Defragment system files at startup” feature by checking the box next to the “Always” option.
• After the system restarts, the message “Defragmentation of the Windows 7 registry” will be displayed on the screen.

The duration of the first defragmentation procedure may take some time. All subsequent times, the action will take no more than a few seconds. To disable registry defragmentation, you need to open Defraggler and disable this feature.

5. RAM diagnostics and disabling services in Windows 7.

Checking installed memory modules for the presence of certain failures and problems is performed using a built-in system utility called “Diagnostics of computer RAM problems”, it is launched as follows:

• Open the Start menu.
• In the search for files and programs field, enter “Memory diagnostics”.
• In the search results, select “Diagnostics of computer RAM problems.”
• In the utility window, click on the recommended check option after reboot.
• After the system restarts, the RAM diagnostic screen will appear. You should wait until the diagnostics are completed, which will be followed by Windows rebooting and displaying an interface with the results of the work done.

To speed up the operation of a PC or laptop, you can disable rarely used OS services; to do this, you should follow the steps below:

• Open Start and go to Control Panel.
• You can change the view mode to Small Icons for greater convenience and find an icon called Administration.
• Select the item with services.
• To disable an unnecessary service, select it and double-click the left mouse button on its name.
• After opening the special control panel for the marked service, go to the “Startup Type” menu and select “Manual”, and then click “Stop”.
• The changes are confirmed by pressing the “Ok” key.

Hello.

I get asked questions of this nature quite often (as in the title of the article). I recently received a similar question and decided to write a short note on the blog (by the way, you don’t even need to come up with topics, people themselves suggest what interests them).

In general, an old laptop is quite relative, it’s just that different people mean different things by this word: for some, old is something that was bought six months ago, for others it is a device that is already 10 years old or more. It's quite difficult to give advice without knowing what specific device it is. we're talking about, but I’ll try to give “universal” instructions on how to reduce the number of brakes on an old device. So, …

1) Selection of OS (operating system) and programs

No matter how trivial it may sound, the first thing you should decide on is operating system. Many users don’t even look at the requirements and install Windows 7 instead of Windows XP (even though the laptop has 1 GB of RAM). No, the laptop will work, but there will be slowdowns. I don’t know what the point is - working in a new OS, but with brakes (in my opinion, it’s better in XP, especially since this system is quite reliable and good (still, although many criticize it)).

In general, the message here is simple: see the system requirements of the OS and your device, compare and select best option. I'm not commenting here anymore.

You should also say a few words about the choice of programs. I hope everyone understands that the speed of its execution and the amount of resources it will require depend on the algorithm of the program and the language in which it is written. So, sometimes when solving the same problem, different software works differently, this is especially noticeable on older PCs.

For example, I still saw the times when the much-vaunted WinAmp when playing files ( True, the parameters of the system unit now, for the life of me, I don’t remember) often jammed and “chewed”, despite the fact that nothing else was running. At the same time, the DSS program ( This is a DOS player, now probably no one has heard of it) played calmly, and clearly.

Now I’m not talking about such old hardware, but still. Most often, they want to adapt old laptops for some task (for example, viewing / receiving mail, as some kind of directory, as a small general file exchanger, just as a backup PC).

Therefore, a few tips:

• Antiviruses: I’m not an ardent opponent of antiviruses, but still, why do you need it on an old computer on which everything is already slow? In my opinion, it is better to sometimes check disks and Windows with third-party utilities that do not need to be installed on the system. You can see them in this article:
• Audio and video players: The best way- download 5-10 players and check each one yourself. This way you can quickly determine which one is best to use. You can find my thoughts on this issue here:
• Browsers: in my review article for 2016. I cited several lightweight antiviruses, they can be used quite well (). You can also use the link above, which was given for players;
• I also recommend having on your laptop some set of utilities for cleaning and maintaining Windows OS. I introduced the best of them to readers in this article:

2) Optimizing Windows OS

Have you ever thought that two laptops with the same characteristics, and even with identical software, can work with at different speeds and stability: one will freeze and slow down, and the second will quickly enough open and play videos, music, and programs.

It's all about the OS settings, the "garbage" on the hard drive, in general, the so-called optimization . In general, this point is worthy of a whole huge article, here I will give the main thing that needs to be done and give links (fortunately there are similar articles on optimizing the OS and cleaning it - I have a lot!):

1. Disabling unnecessary services: By default, there are quite a lot of services running that many people don’t even need. For example, Windows auto-update - in many cases this causes slowdowns, just update manually (once a month, say);
2. Setting up the theme, Aero environment- a lot also depends on the chosen topic. The best option- choose a classic theme. Yes, the laptop will look like a Windows 98 PC - but resources will be saved (most people don’t spend most of their time staring at the desktop anyway);
3. Setting up startup: For many people, the computer takes a long time to turn on and starts to slow down immediately after turning it on. Usually, this is due to the fact that Windows startup contains dozens of programs (from torrents with hundreds of files to all kinds of weather forecasts).
4. Disk Defragmenter: from time to time (especially if the file system is FAT 32, which can often be found on older laptops) it is necessary to defragment. Programs for this - great amount, you can do something;
5. Cleaning Windows from “tails” and temporary files: often when you uninstall a program, various files and registry entries remain from it (such unnecessary data is called “tails”). All this needs to be removed from time to time. I provided a link to the utility kits above (the built-in cleaner in Windows, in my opinion, cannot cope with this);
6. Check for viruses and adware: Some types of viruses can also affect performance. You can find out about the best antivirus software in this article: ;
7. Checking the CPU load and which applications are creating it: It happens that the task manager shows CPU usage at 20-30%, but the applications that load it do not! In general, if you are suffering from incomprehensible processor load, then here is what you need to know about it.

3) “Fine” work with drivers

Very often, many people complain about slowdowns in games on old computers and laptops. You can squeeze a little performance out of them, as well as 5-10 FPS (which in some games can be, as they say, a “breath of air”) by fine-tuning the video driver.

In general, this should be done carefully. At the very least, download those drivers that have positive reviews and whose description includes your equipment.

4) Temperature check. Cleaning from dust, replacing thermal paste.

Well, the last thing I wanted to dwell on in such an article is temperature. The fact is that no one ever cleans old laptops (at least those that I have seen), not from dust, nor from small specks, crumbs, etc. “good”.

The new laptop works quickly and smoothly, but over time problems arise with the speed of processing requests. Most often, the reason for poor performance is the actions of the users themselves, so if your laptop is running slowly, reconsider your attitude towards its use.

Common Causes

If the laptop takes a long time to load everything, then the following factors may be causing the problem:

• Excessive system clutter with files and programs.
• Action of viruses.
• The autorun list is crowded.
• A large number of running processes.
• HDD fragmentation.
• Using an economical power supply.
• Cooling system clogged.
• Obsolescence of equipment.

Sooner or later, the system will still start to slow down, but you can keep it in working order for a long time on your own if you properly care for your laptop.

System optimization

If your laptop starts to run slowly, pay attention to how much free space there is on your hard drive. 12-15% of the total volume should remain free on the system partition. You can fill more space, but then “brakes” will arise, because fragments of the file table will begin to be laid out in free sectors of the disk, the search for which will take more time.

Therefore, delete unnecessary files and uninstall unnecessary programs so as not to take up useful space with junk. To uninstall programs, it is recommended to use the Revo Uninstaller utility, which allows you to immediately clean the system of empty folders that remain after removing applications.

Don't forget to destroy temporary files and clean the registry. Use for system optimization free program CCleaner - you can do everything through it necessary actions, from deleting temporary files to cleaning the startup list.

Note: When deleting temporary files through CCleaner, uncheck the boxes of the browsers you use so as not to erase your browsing history and saved passwords.

You can also clean startup using the built-in tools. On Windows 10, the startup list is available in the task manager:

Since you are in the task manager, move to the “Processes” tab and see which programs are loading the system and how much. If there are unnecessary processes (for example, Skype is running, but you are not using it or waiting for messages), end them to reduce the load.

If Windows 7 is loading slowly, follow these steps:

If you leave a minimum of programs, then the laptop's resources will be directed to loading Windows, and not launching third-party software. In addition, if your laptop is slow, be sure to check it for viruses. Use not only the installed antivirus, but also the Dr. cleaning utility. Web Cure It.

Disk Defragmenter

If your laptop has an HDD drive, do not forget to periodically defragment it. During the work process, the data is broken into parts, that is, fragmented. In search of parts of files, the disk head is forced to wander across the entire surface, which ultimately affects the response speed. Disk defragmentation allows you to collect pieces of data in one place.

Attention: if the laptop has an SSD drive, then defragmentation is not necessary and even harmful, because solid-state drives use a different technology than HDDs.

If your disk is more than 10% fragmented, defragment it. To remember to perform this procedure constantly, click “Change settings” and enable scheduled optimization.

Power settings

There are several plans available in the laptop power options. If you haven’t created your own plan, there will be three of them:

• Energy saving.
• Balanced.
• High performance.

The name of the schemes directly indicates their purpose. If you have the energy saving mode set, then good operating speed is out of the question - the laptop will try to consume a minimum of resources. To fix this, you need to install a different power plan.

Try to install a balanced circuit first so that the laptop is sufficiently productive, but does not discharge in half an hour. If a program or the entire system is still running very slowly, set it to High Performance mode.

Cleaning and updating components

If neither system optimization nor even a complete reinstallation of Windows helps, then you should pay attention to the physical condition of the laptop. Perhaps it slows down and freezes because the cooling system is clogged. How to fix it? Disassemble the laptop and clean it from dust, and replace the thermal paste. You can do this yourself by first finding a laptop disassembly diagram, but it’s safer to contact a service center.

We should not forget that “smart” technology quickly becomes obsolete. Therefore, if you are using an old laptop, then do not be surprised that Windows 8 slows down on it, and some programs do not start at all. You can try to update individual components (processor, motherboard, hard drive, RAM), but in the case of a laptop it’s easier to buy a new model.
