How do I know when the computer was turned on in my absence? Damage to the processor socket. How to check if a SATA controller is operating in AHCI mode

If you turn to system administrator and ask the question, what is the weakest link in a computer? - you will get the answer that this is exactly the HDD, because it is practically the only mechanical element of the system that slows down the entire computer. In this regard, many manufacturers were looking for a way out, at least some opportunity to speed it up, also with SSD. The way out became visible when using AHCI.

AHCI disk mode includes several main differences (there are 3 of them), which make it a priority in using all disk drives, except for the outdated IDE. The main features of the mode:

• Hot Plug - allows you to hot swap computer components (disks). Thus, there is no need to turn off and de-energize the PC, you can change HDD, SSD right in the operating mode. This is important for server stations, where disconnection is unacceptable and is simply convenient for everyone who uses multiple disks;
• NCQ - support for "deep" sequence of commands, that is, it is able to set up a more efficient trajectory of movement of the head in mechanical and significantly increases the output in SSD;

• TRIM is primarily applicable to SSDs, as it guarantees a significant increase in speed.

AHCI mode allows you to take advantage of all these benefits, and most likely you have the option to turn it on. If you are using an SSD, then you probably need to enable it to see the proper speed of its operation, applicable to both SATA II and SATA III, except for outdated IDE drives. Therefore, if you are in doubt about which ide or AHCI mode to choose, the latter is definitely an advantage.

How to check if AHCI mode is enabled?

First of all, you need to find out whether it is worth taking further switching, perhaps you already have it active. There are several places that show the information you need: Device Manager and BIOS.

• Click Start, where RMB on "Computer" and click on "Properties";
• Now select "Device Manager";

• Next expand the section "IDE ATA / ATAPI controllers";
• Check for a section titled AHCI.

In the absence of such an item, you can find out that it is inactive. Also consider another option via BIOS (UEFI):

• Go to BIOS by pressing Del or F2 (possibly other keys) when starting the computer;
• You should go to the section called SATA or Storage in different variants until you find SATA Mode / Configuration, where the mode will be shown.

Do not change the connection mode at this stage, as this is fraught with system errors. It is best to enable AHCI mode in BIOS and install software new windows, which guarantees normal processing of the mode, but this is quite radical.

How to enable AHCI mode in Windows 7?

The most relevant and common system in which we will perform actions. It should also be noted that if you are installing a new disk, then you can freely switch the AHCI mode without any consequences. There are also several options for activating AHCI: through the registry and through the utility. A more correct option would be through the registry in order to prepare the system for further changes, the latter method will simply help to solve overdue errors in the computer.

• Press Win + R and enter regedit;
• Follow HKEY_LOCAL_MACHINE \\ SYSTEM \\ CurrentControlSet \\ services \\ msahci;
• Change the Start option to 0;

• Find the lastorV section here;
• Also replace Start with 0.

Now you can enable AHCI mode in BIOS and Windows will correctly detect it by setting required drivers. Alternative way involves changing the mode initially and then simply fixing the error. To do this, use the official Microsoft Fix it utility. After installation, run the check and the failures will be eliminated, you may need to run from safe mode.

How to enable Windows 10 AHCI mode?

In general, the actions are not significantly different, let's consider the differences in editing the registry.

• In the same section, as in Windows 7, you need to change the Start parameters in the iaStorV and storahci folders to 0;
• Expand each of the above sections and go to the StartOverride subsections, where parameter 0, set the value to 0.

We managed to turn on the mode AHCI Windows, but it should be noted that it is better to make the first launch in safe modeto avoid unnecessary problems... During initial power-up, the AHCI operating mode will set required drivers automatically.

It should be noted about the distinctive features, how to enable AHCI mode in Windows XP and other legacy versions.

Despite the fact that XP does not support this mode at all, there are drivers that extend these capabilities, although this is not safe.

You should also think about whether it is worth it, because if the computer is very weak for more modern systems, then the speed gain will be negligible. Also, the AHCI controller mode in Vista is included in the same way as the "seven".

So, the AHCI sata mode is easy to enable, and the system will reward you for your efforts with a speed boost. Usually, there are no problems with changing the controller, but if you encounter them, then just run the Microsoft Fix it utility. AHCI is mandatory for using SSD drive, otherwise you will not be using its full speed.

If you still have questions on the topic "What is AHCI mode and how to configure it?", You can ask them in the comments

Every month mobile operators provide their customers with new opportunities to simplify the use of their number. For this, there are subscriptions to options that may be paid. Content connection is carried out by the client or independently during the campaign by the operator. Therefore, to answer the question of how to find out which service connected to Megafon without the user's consent, you can use short command or a call to a consultant. For convenience, use a personal account.

Sometimes, when the service is connected to a mobile phone, a binding to paid subscription options. Often, customers do not use the content they receive, but the subscription fee is charged every month or day. A paid service could be connected independently under a promotion, and certain time had free features... Therefore, the client can find out about their content subscriptions, for which money has begun to be withdrawn.

To check availability paid services there are several ways on Megaphone. Before this, the client needs to know what the subscriptions linked to his number are aimed at. In Megafon, when viewing connected services, the following content groups are distinguished:

1. Additional features to help make communication easier.
2. Entertaining content.

To check the availability of connected services, use several methods. Usually the client is offered to call on a short three-digit phone number. Otherwise, you can use Megafon's personal account or call a consultant cellular communication.

Methods for checking paid services

How to find out about the connected paid service on Megafon, if it is not possible to use your personal account? Several options are provided for operator users. All methods using the number use the combination * 105 #.

To check the availability of paid services on Megafon, you can use the command that will immediately display on the screen cell phone connected options. To do this, there are 2 ways to enter a digital value:

1. Megafon communication users will need to dial *105*559# .
2. Another combination is the introduction *105*11# .

These methods will allow you to immediately display mobile phone subscriptions. Often, subscribers are connected to the options "Live balance" or "Answering machine". When the client has just purchased a SIM card, these services do not charge a fee for the first 14 days.

USSD command

Megafon provides its customers with the opportunity to use codes to identify balance and other functions. Commands of the USSD format are typed with 2 asterisks, between them there are combinations of numbers. To identify the connected content on your number, you will need to enter * 105 * 11 #. After that, the subscriber receives a response, where the connected options are displayed in the form of a list.

Good to know! If you dial * 105 * 5032 #, then the subscriber will be answered with other services on this number.

SMS

In addition to the command in USSD format, Megafon users can use a message on special number... To find out about paid additional content on the phone, you will need to send an SMS with the text where "info" is written. The number to send the message is a short four-digit code 5051.

After sending the command via SMS, you will receive a response message. It will indicate the availability of paid options. Additionally, information will be provided on how to disable content.

"Service Guide"

Operator Megafon provides users with convenient control of the connected functions. This requires login to personal Area, and turn on the "Service Guide". This helps subscribers to easily handle balances by minutes, messages and Internet traffic.

It is interesting! The service informs users about new promotions and bonuses. All news and novelties on tariff plans will be sent to the number immediately in the form of notifications. The function is convenient when replenishing the balance of a SIM card.

To register in the service, you will need to refer to the official Megafon website for your area. In the required line, you must specify your data, and then you should receive a password. To do this, use the phone to dial the command * 105 * 00 #.

The service provides a one-time password every time you log in. To receive it, you will need to write a message with “00” written and send it to 000105. Otherwise, you can click on the “Get code” link, which redirects the user to the website.

Attention! To find out about the connected subscriptions in the service, you will need to go to the "Options and Services" tab.

Call an online consultant

You can find out about paid options on the Megafon number by calling contact center... To contact the operator, enter 0500 or dial 0500559. The subscriber is immediately connected to the autoinformer, which provides options, among them there will be a number for communicating with a consultant. This method will take time to get a response to the connected options.

Management of paid services

To manage the connected functions on the number will help "Service Guide". The "Options and Services" tab contains all the information on how to disable or enable subscriptions. Otherwise, you can send a message where the text indicates "STOP". The recipient's phone is where the unnecessary information is sent from.

Disable unnecessary functions it is possible through the operator's office, or by calling the company using 0500. At the request of the subscriber, the operator will suspend the activity of unnecessary options. To go to the office you will need to have your passport with you. If necessary, employees can reimburse funds that were debited without the owner's knowledge.

Paid functions of Megafon are able to connect on their own if the subscriber used another service or the client himself. When funds are debited from a cellular account, not everyone likes it. Therefore, users try to disable unnecessary features. To do this, use USSD format commands, messages, personal account and "Service Guide". If the client does not understand this, then it is recommended to contact the operator's office.

VPN connection check

Checking the VPN connection configuration

A necessary step in working with a VPN connection is to check the configuration to ensure that the system can correctly create channels on the network. Follow the steps below to test your VPN connection.

1. On the client, click right click mouse on the Company ABC VPN Connection and select in context menu Connect.
2. Click the Connect button.
3. Click the OK button to accept the credentials. After that, the connection will be created.

You can test the connectivity by pinging the domain controller.company.com. Since the system has passed the health checks, this connection is allowed full access to all "intranet resources. Follow these steps to test connectivity."

1. After the Company ABC VPN Connection is established, select All Programs-Accessories-Command Prompt from the Start menu.
2. Enter the ping company command. com and press the key .
3. A response should appear from the IP address.
4. Select Connect To from the Start menu to open the Connections window.
5. Select the Company ABC VPN Connection and click the Disconnect button.
6. Click the Close button.

NPS provides detailed connection information that was lacking in previous versions Windows. IN Windows Server 2008 R2 finding the root cause of legacy VPN connection problems has become a simple task.

Managing Inoperative VPN Clients

In the above example, everything was smooth and there were no performance issues. But if the client did not pass such a check, then the inoperable elements must be restored. A previously configured health check checks if windows firewall... To test the recovery capabilities, turn off Windows Firewall and reconnect.

1. On the VPN client, select Control Panel from the Start menu.
2. Click on the Security item.
3. Click on Windows Firewall.
4. Click on Change Settings.
5. Set the radio button to Off (Not Recommended) and click the OK button.

Introduction

SSD drives are usually faster than magnetic drives hard drives... Of course, some flash drives have a very mediocre write speed, but in general, it is solid state drives are now setting the pace, overshadowing the evolution of traditional hard drives.

True, SSD drives are not only faster, but also much more expensive than conventional HDDs. Every gigabyte of SSD is expensive. And if there is an option to free up several gigabytes by disabling unnecessary Windows services and features, then this cannot be neglected.

It is also worth noting that there are many individuals on the forums of computer enthusiasts who claim that a few simple Windows optimizations will help increase performance. But is it really so?

In this article, we decided to take a closer look at the most popular SSD tweaks and determine, using a test, how they affect system performance. Basically, we have to answer only two simple questions - is it possible, using certain system tweaks, to free up space on system disk and increase the performance of your computer?

In addition, we are planning to test two different solid state drives to see if the effect depends on specific model SSD, or these tweaks will work for any drive. It is possible that these tweaks are completely useless and there is no way to make an SSD run faster.

We will test nine of the most popular SSD tweaks for the Windows 7 operating system:

1. Disable System Restore.
2. Disable data indexing.
3. Disable paging file.
4. Disable hibernation.
5. Disable prefetching (read ahead).
6. Disable flushing the Windows entries cache.
7. Disable SuperFetch and Windows Search.
8. Disable ClearPageFileAtShutdown and LargeSystemCache.
9. Setting up a power plan.

AHCI Mode and TRIM Command

Before proceeding with subtle system tweaks, you need to make sure that the SATA controller is set to AHCI mode, and the TRIM command is supported by Windows 7. Both of these settings, strictly speaking, cannot be classified as optimizations for SSDs - rather, this is a requirement for the computer configuration that uses a solid state drive.

AHCI (Advanced Host Controller Interface) mode is a specific SATA controller mode that allows hot swapping sATA drives and NCQ (Native Command Queuing) technology. Using NCQ provides higher performance of the disk subsystem.

This is especially true for flash drives where a multi-channel controller is used: an SSD is much better suited to the simultaneous execution of multiple commands. That is why solid-state drives provide maximum performance at high queue depths and the benefits from using NCQ can be quite noticeable.

Do not forget about another important argument in favor of AHCI: only in this mode of controller operation can you use the support of the TRIM command, which is provided by operating system Windows 7. TRIM support is essential for SSD drives as it helps to save high productivity drive over a long period of time.

According to Wikipedia, TRIM - a command that allows the operating system to notify the solid-state drive about which data blocks are no longer used and can be cleared by the drive itself. Using TRIM allows the SSD to reduce the impact garbage collection (garbage collection), which would otherwise result in a decrease in the write speed to the affected sectors. TRIM support provides more stable write speed and reduces wear and tear on free memory cells.

How to check if a SATA controller is operating in AHCI mode

The AHCI mode of the SATA controller can be set in the BIOS or UEFI settings of your motherboard. Most modern motherboards it is installed by default, but make sure it is correct bIOS setup follows exactly before installing Windowsrather than after. If Windows is already installed, you need to check if AHCI mode is enabled:

• In the "Start" menu select "Control Panel".
• On the "View" tab, select the "Small icons" display mode.
• We select "Device Manager".
• In the "Device Manager" we find the branch "IDE ATA / ATAPI controllers", expand it and look for aHCI controllers.
• If the AHCI controller is on the list, then the system operates in AHCI mode.
• If there are no AHCI controllers in the list, then the system is started without AHCI support.

• If Legacy IDE mode is used instead of AHCI, it is recommended to switch to ACHI mode. However, with the OS installed, this will be a little more difficult. More on this in microsoft support article .

How to check if the TRIM command is enabled

If TRIM support is enabled in Windows 7, then the operating system sends appropriate commands to the SSD. Checking if TRIM is working is also pretty simple:

• In the "Start" menu in the search field, enter cmd.
• Right-click on the cmd.exe executable file and select "Run as administrator".
• IN command line enter "fsutil behavior query DisableDeleteNotify" (without quotes).
• If the computer issues DisableDeleteNotify \u003d 0, TRIM support is enabled.
• If DisableDeleteNotify \u003d 1 is displayed, TRIM support is disabled.

Disabling System Restore

Let's move on to describing more subtle system optimizations. The first of these in line is to disable System Restore - built-in Windows systems rollback (recovery) of the system using the principle of "checkpoints".

Disabling System Restore serves two purposes. First, you reduce the number of writes to the SSD, which increases its durability. Today there are different opinions as to whether or not to worry about unnecessary write operations on an SSD. The number of write cycles is the main parameter that tells us about the longevity of the memory cells, on the basis of which solid state drives are created. Some users believe that there is no need to worry: you are unlikely to see the day when your SSD storage cells stop storing data. Other users, on the other hand, do their best to minimize the number of rewrite cycles. There is no definite answer as to which of them is right. But if you don't rely on chance and consider yourself to be someone who does not want to take risks, then disabling System Restore is a good option to reduce the load on memory cells. Let's add that System Restore "checkpoints" are not available for the TRIM command and regular use of this windows functions has the potential to degrade drive performance over time.

The second reason to refuse system recovery is to save free space on the system disk. Checkpoints created by System Restore are stored on the system disk itself and "eat off" expensive disk space on the SSD. However, they do not always provide a full rollback of the system. As a rule, it is safer to have a complete system image created using a specialized utility (Norton Ghost, Acronis True Image). You can "deploy" such an image to disk in a matter of minutes and you will be confident that you will be able to return to the working system. In addition, you do not need to store such an image on the system disk itself - for these purposes, you can use a regular hard drive or an external disk.

How to disable System Restore

• Right-click on the "Computer" icon in the "Start" menu and select "Properties".
• Select the "System Protection" tab.
• Click on the "Configure" button.
• Check the box next to the "Disable system protection" item.

Greetings, dear readers! Quite recently, I received an email from one user. A user asked me this question: employees during my absence from the workplace?

In other words, does the computer keep any kind of log that records the operations performed by the user on the computer.

To answer this question in detail, I decided to write a post on this topic. When you turn on the computer, from this moment the recording of the actions performed at the computer begins. To be more precise, an "event log" is recorded, which indicates the date and time of a specific operation being performed, and also records running processes of the operating system.

How do I know who turned on my computer?

So let's open this event log. Click on "Start" and in the search bar enter - "Event Viewer".

As a result, the main window "Event Viewer" will open, in which we will need to follow the link " Windows logs \u003d\u003e System ".

In the next window, an event window will open, consisting of a table in which, as you can see, the date and time are displayed, as well as the event code, category.

By looking at this table, you can determine when the computer was turned on and off. For example, on September 9, I turned off the computer, and the next turn-on was done by me on September 10. That is, in my absence, no one used a computer.

Like this in a simple way you can determine when your computer was turned on and off. And you dear readers, do you know any other ways to determine if the computer was turned on in your absence? I would be glad to hear in the comments.

That's all for me. Now you will be aware - How to find out when the computer was turned on .

In the next article I will tell you \u003d\u003e
