The errors that are caused by the BIOS of your computer can get annoying as they can be hard to fix for they are really dangerous and won’t be resolved by simple fixes. This is because of the fact that these kinds of errors do not even allow you to load your operating system as it throws the error even before you can access your computer. One of these errors is the “Error 0199: System Security – Security password retry count exceeded”. Fixing this error can be quite tricky but you need not worry for you will be guided in doing so. Simply follow the given instructions below.

Option 1 – Try to update the BIOS

Updating the BIOS can help you fix the “Error 0199, Security password retry count exceeded” error but as you know, BIOS is a sensitive part of a computer. Even though it is a software component, the functioning of the hardware depends on it largely. Thus, you must be careful when modifying something in the BIOS. So if you don’t know much about it, it’s best if you skip on this option and try the other ones instead. However, if you are well-versed in navigating the BIOS, then follow the steps below.

• Tap the Win + R keys to open the Run dialog box.
• Next, type “msinfo32” in the field and press Enter to open System Information.
• From there, you should find a search field on the bottom where you have to search for the BIOS version and then press Enter.

If your Windows 10 computer or laptop keeps on going to sleep randomly even when you’re using it, read on as this post will walk you through the process of resolving the problem. There are a number of users who reported about how their Windows 10 computers would automatically go into Sleep Mode. One particular user claimed that when he installed a fresh Windows 10 version he began experiencing the same problem. It turns out that the screen goes to sleep but what’s odd is that the power lights and the keyboard are still working. The computer is also warm to touch which shouldn’t be the case when it is in sleep mode. And when some users tried checking the event log, it showed them that the computer didn’t actually go into sleep mode but it shut down instead. To fix this issue, here are some possible fixes that could hopefully work.

Option 1 – Edit the Power Plan settings using Control Panel

• Click the Cortana button and type “control panel” in the field and select the appropriate result to open Control Panel.
• After opening Control Panel, click on the Power Options.
• From there, select the “Edit Plan Settings” option and make sure that the option to “Put the computer to sleep” is set to Never.

Option 2 – Edit the Power Options using Settings

• Tap the Windows key + I to open the Settings app.
• After that, select Settings and go to the Power & sleep section.
• Next, set the system to “Never” when the device is running on battery power or plugged in.
• Now restart your computer to make sure that everything is working properly.

Option 3 – Try running the Power Troubleshooter

Another option that could help resolve the problem is the Power Troubleshooter. This built-in troubleshooter in Windows can help you get things up and running again.

Option 4 – Troubleshoot Sleep Mode issue in a Clean Boot State

The issue with Sleep Mode might be caused by some third-party programs installed on your computer. This program might be the one that puts your computer to sleep and so to isolate this possibility, you have to put your PC in a Clean Boot State using the steps below.

• Log onto your PC as an administrator.
• Type in MSConfig in the Start Search to open the System Configuration utility.
• From there, go to the General tab and click “Selective startup”.
• Clear the “Load Startup items” check box and make sure that the “Load System Services” and “Use Original boot configuration” options are checked.
• Next, click the Services tab and select the “Hide All Microsoft Services” check box.
• Click Disable all.
• Click on Apply/OK and restart your PC. (This will put your PC into a Clean Boot State. And configure Windows to use the usual startup, just simply undo the changes.)
• After that, try to install the Windows Updates or upgrade again.

Option 5 – Try checking the Sleep Advanced Settings

• Click on the Windows key and type “control panel” in the field and select the related search result.
• Next, select the Security and Maintenance option and click on the Power Options.
• After that, you have to select the Change Plan Settings but keep in mind that this option is barely readable so you need to read each option carefully.

Option 6 – Try installing v9 or 10 of the MEI or Intel Management Engine Interface

Note that this option only applies to users who are using an HP laptop. And if your motherboard does not support Hybrid Sleep, you might have to downgrade the Intel MEI to version 9 or 10. To install v9 or v10, you need to go to the HP Drivers & Downloads page and look for the MEI driver version 9 from the website’s Driver Chipset section. Once you’ve downloaded the driver, install it and if a dialog box warning pops up, simply ignore it and proceed.

Option 7 – Update the device drivers

• Reboot your computer into Safe Mode with networking support.
• Tap the Win + R keys on your keyboard to open the Run dialog box.
• After that, type “devmgmt.msc” in the field and hit Enter or click OK to open the Device Manager.

In case you don’t know, the Windows Registry contains a System Hive which is a core part of Windows. The Windows operating system store various settings, options, and configurations. And if you encounter a Device Manager Error 49 for a device then it means that the system hive has exceeded its size limit. Worry not for this post will provide you with possible solutions that can help you in fixing error code 49. You will see the following error message when you encounter error code 49:

“Windows cannot start new hardware devices because the system hive is too large (exceeds the Registry Size Limit), (Code 49)”

There are instances when it may so happen that the device or devices are no longer attached to the computer but they are still listed in the system hive of the registry. For instance, if you were removing hardware and application for years but they weren’t removed from the registry then the size of the system hive keeps on growing until it hits the maximum limit. As you know, making changes in the registry manually, no matter how knowledgeable you are on such things is not sage since the registry is not only important but also complex. In addition, the System Hive is also a permanent part of the Registry associated with a set of files that contain information related to the configuration of the computer on which the OS is installed. To resolve this error, you must remove or uninstall any hardware devices that are no longer in the system. In fact, the Device Manager hides them by default so you need to enable hidden or non-present devices. Follow the instructions given below to set the Devices Manager to display devices that are no longer connected to the computer. Step 1: Tap the Win + R keys to open the Run dialog box. Step 2: After that type in “cmd” and hit Enter to open the Command Prompt. Step 3: Type “set devmgr_show_nonpresent_devices=1” in the Command Prompt and hit Enter to enable the hidden devices option. Step 4: After that, exit Command Prompt and tap Win + X + M to open the Devices Manager. Step 5: After opening the Devices Manager, click on View and then select the “Show hidden devices” option. This will show you all the devices that are not connected to the computer but are still mentioned. Step 6: Next, select a non-present device and click Uninstall from the Driver tab. Step 7: After that, repeat what you’ve done on step 5 for any other device that you no longer use. Step 8: Restart your computer. You can check the device Properties dialog box in the Device Manager after you’re done removing all the useless devices, to check if the error is now fixed or not. Moreover, you can also try running the Hardware and Devices Troubleshooter as it can also help resolve hardware-related problems. To use it, refer to the steps below.

• The first thing you need to do is click on Start and then on the gear-like icon to pull up the window for Settings.
• After opening Settings, look for the Update and Security option and select it.
• From there, go to the Troubleshoot option located on the left-hand side of the list.
• Next, select Hardware and Devices from the list and open the Troubleshooter and run it. Once it is doing its job, wait for it to complete the process and then restart the system.
• After the system restarts, check if the problem’s now fixed. If not, refer to the next option given below.

Privacy is a hot topic lately in all circles so naturally themes like private or incognito browsing pop up immediately as discussion topics. Naturally, when discussing private or incognito browsing it is very important to understand what exactly private or incognito browsing is, what does it do and how it works in order to shed some light on is it really private and safe as we are told. So, when you browse the internet normally websites have tendencies to save your browsing data, save cookies, remember passwords, etc in order to provide you with a better surfing experience next time you visit that same site. Private or incognito browsing treats you as a completely new user which is the first time visiting a given website. It clears all your data, including your browsing history, cookies, etc., on exiting. Every website you visit in private or incognito mode treats you as a new visitor, even if you have visited it before in incognito mode. And basically, that's it. So is it really private? No, it is just a non-remembering mode of internet browsing where after your browsing session history and other data is cleared from the browser, but while you are on the internet you are pretty visible to all like any other normal user. There are a lot of misconceptions and wrong thinking about browsing the internet in this mode so let's take a look at some typical ones.

1. The government and other companies can not track me

   Many people think that the Government cannot trace their identity when they surf privately. This is only a myth. There are many ways by which the Government can reach you if you do something illegal. When you surf online, you are connected with an ISP of your area, which helps the officials track your location.

2. Virus and other malware can not infect me while in private or incognito mode

   Many people think that private mode protects them from virus and malware attacks. It is not true because malware and viruses can enter your PC through a software download, phishing email, etc. To protect your PC from virus and malware attacks, you should have good security software.

3. My IP address is hidden when I am in incognito or private browsing mode

   This is not 100% true. If you search “What is my IP” in incognito and standard mode, you will get the same results. This means that websites can view your IP address in private mode also. Using a VPN would be a good option if you want to hide your IP.

4. I can not be tracked via ads

   Since cookies are deleted after exiting private browsing, many people think that ads cannot track them. When you surf in incognito mode, the browser saves cookies in a temporary mode, allowing ads to track you during your entire private browsing session.

5. I am not visible when I am in incognito or private

   You may think if you sign in to your Gmail or other social media accounts in private mode, no one will see you online. This is not true. It does not matter whether you have signed into your account in normal mode or incognito mode; others can always spot you online.

In your regular browsing mode, you may have some addons, extensions, themes, etc installed and you can use them. They may track your activities. The data is deleted when you exit the browser. When you use the private browsing mode, the browser is loaded in its original form, typically without the installed addons, extension, themes, etc. The data gets deleted when you exit the browser. This mode doesn’t save data to disk but keeps it in memory during the current session. If you are really concerned about your privacy we have articles about using DuckDuckGo and deep web where you can be sure that your browsing sessions are encrypted.
