A Quick Guide to Fixing Error C00D1199

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.
• Now click on the Change advanced power settings button and a new window will appear.
• Then look for the “Sleep” option and expand it to select the Allow hybrid sleep” option. Turn this option off and close all the opened windows.
• Reboot your computer and check if your computer now functions properly. If it still didn’t work, you may have to reverse the changes you’ve made.

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.
• After opening the Device Manager, update all the outdated Device drivers on your computer.
• Next, right-click on all the driver entries that are appropriately labeled, and then click the Update driver option.
• Now restart your PC and check if your computer is now back to normal.

If you are one of the few users who is still burning CDs and DVDs, you might have come across an error that says, “Medium Speed Error” or “Power Calibration Error”. There are several factors that could cause this error but it’s most likely that the CD/DVD burner wasn’t able to determine the Optimum Power Calibration rate properly. So what is Optimum Power Calibration rate? It is a test that runs before the burning process to regulate the optimal laser power needed to complete the job. And if this process malfunctions, obviously, you won’t be able to burn the content on your CD or DVD. There are also cases when the Power Calibration error pops up for some small issues that have nothing to do with the regulation of laser power. Here are some quick fixes you can try to resolve the Power Calibration error when burning a CD or DVD.

Option 1 – Make sure you’re using good quality CD or DVD

A lot of burning issues stem down to the purchase of low CDs or DVDs to make sure that what you are using has good quality for it is not always a good idea to purchase cheap products as cheap products could also mean cheap quality.

Option 2 – Try burning at lower speeds

If you’re certain the problem is not with the CD or DVD you are using then you can try burning again, this time at lower speeds. There are instances when doing things quickly can end in a disaster such as the “Medium Speed Error” or “Power Calibration Error” you’re getting.  To fix the problem, you have to burn at a slower speed and just take the time to wait until the burning process is done.

Option 3 – Try updating your burning software

It’s always a good idea to check if the burning software you’re using requires an update especially if it’s throwing up “Medium Speed Error” or “Power Calibration Error”. Thus, you need to update your burning software right away and then try to burn your CD or DVD once the update has been completed.

Option 4 – Try cleaning the disk drive

You might want to consider cleaning the disk drive using several tools in the market that is designed to clean the disk drive. These tools work on removing dust particles from the lens which helps a lot in the burning quality. Aside from that, it also helps in reducing errors like “Medium Speed Error” or “Power Calibration Error”. So give this option a try as it might time for a disk drive cleanup.

Option 5 – Try to disable the IMAPI

If none of the options given above worked, you might want to disable the IMAPI or Image Mastering Applications Programming Interface. How? Refer to the steps below.

• Open Control Panel by simply clicking the Start button and then typing “control panel” in the field.
• Control Panel should pop up in the search results. Once you found it, click it to open it.
• Next, select System Security > Administrative Tools and then click Services.
• After that, you’ll have to search for the “IMAPI CD-Burning COM Service” option.
• Then right-click on it and select Properties.
• From there, switch the Startup Type from “Enabled” to “Disabled”.
• Now click on Apply and then restart your PC.

If your Microsoft Edge browser and Windows Store apps are now unable to connect to the internet after you have just installed the newly released Windows 10 v1809 October 2018 update, then this post might help.

How does a computer get infected with a browser hijacker?

Browser hijackers can get into a computer by some means or other, for instance via file sharing, downloads, and email also. Many web browser hijackings originate from add-on applications, i.e., toolbars, browser helper objects (BHO), or extensions added to web browsers to give them extra features. A browser hijacker may also come bundled-up with some free application that you inadvertently download and install, compromising your PC security. Common examples of browser hijackers include CoolWebSearch, Conduit, Coupon Server, OneWebSearch, RocketTab, Snap.do, Delta Search, and Searchult.com. Browser hijackers may record user keystrokes to gather potentially valuable information leading to privacy issues, cause instability on systems, drastically disrupt user’s browsing experience, and eventually slow down the computer to a stage where it becomes unusable.

Removal

Some browser hijacking can be simply reversed by discovering and eliminating the corresponding malware software through your control panel. However, many hijackers are really tenacious and need specialized applications to remove them. Also, manual removals demand deep system understanding and thus can be quite a difficult task for novices. Professionals always suggest users eliminate any malicious software including browser hijackers by using an automatic malware removal tool, which is easier, safer, and faster than the manual removal procedure.

As you know, the Mobile Hotspot feature is used to share the internet connection with other devices using Wi-Fi signals. These Wi-Fi signals are later caught by other devices using their Wi-Fi and then the internet connection is shared once they are connected. However, recently, some users reported that their devices weren’t able to see the Wi-Fi network even if their Wi-Fi is on. This kind of problem could be caused by several factors but one of the main ones include the frequency at which the Wi-Fi network is being broadcasted. If you are one of the users who are currently facing this problem, read on as this post will guide you on what you can do if the Mobile Hotspot or Wi-Fi connection does not show up or is not detected on your Windows 10 device. In most cases, there are only two frequencies at which a Wi-Fi network is broadcasted. They are broadcasted either at 2.4 GHz and 5 GHz. The ones that are broadcasted at 5 GHz need specific hardware since it is a newer technology compared to the ones at 2.4 GHz. There are several other pieces of equipment as well as electrical appliances that operate at 2.4 GHz that includes microwaves as well which causes disruption in the signal strength of the Wi-Fi network. Moreover, aside from signal interruption, this issue with the mobile hotspot might also have something to do with the network-related drivers in your computer. Thus, to fix the problem, here are some suggestions you should follow.

Option 1 – Try toggling the Network band or the frequency at which the Wi-Fi network is broadcasted

• First, open the Windows 10 Settings app and then navigate to Network & Internet > Mobile hotspot.
• From there, click on the Edit button located under the Network name, Network password, and Network band.
• After that, set the Network band to be at 2.4 GHz and then click on the Save button.
• Once done, restart the Mobile hotspot in your Windows 10 device as well as the Wi-Fi connection of the device that’s trying to connect to the hotspot.

Option 2 – Try running the Network Adapter Troubleshooter

If the first option didn’t work, you might also want to run the Network Adapter Troubleshooter. You can use it to troubleshoot the problem with the Mobile hotspot, to run it, follow these steps:

• Open the Search bar on your computer and type in “troubleshoot” to open the Troubleshoot settings.
• Next, scroll down and select the “Network Adapter” option from the right pane.
• Then click on the Run Troubleshooter” button.
• After that, your computer will check for any possible errors and will pinpoint the root cause of the problem if possible.

Option 3 – Try updating the Network adapter driver

As mentioned, the problem could also be due to the network-related drivers. So it probably might be the reason why you’re mobile hotspot did not appear or was not detected. That’s why it is recommended that you update the Network adapter driver and to do it, refer to these instructions: Follow the steps below to update your Network Adapter Driver:

• Tap the Win + R keys to launch the Run window and then type in the “MSC” command and hit Enter to open the Device Manager window.
• From there, expand the list of all the network drives and update each one of them.
• Restart your PC and see if it helped in fixing the issue with the mobile hotspot.

Note: If updating the network drivers didn’t help in fixing the problem, you can also try to uninstall the very same drivers and restart your Windows 10 PC. After that, the system itself will reinstall the drivers you just uninstalled. Alternatively, you can also download and install the drivers from the manufacturer’s website directly.

If you encountered an error message saying, “We couldn’t find any drives, To get a storage driver, click Load driver” when you try to install Windows in a VirtualBox machine, then you’ve come to the right place as this post will guide you in fixing this error. This error message is displayed on the screen where you have to choose a partition to install the guest operating system.

To fix the Activation Error Code 0xc03f6506 in Windows 10, use the options provided below as references but before you proceed, make sure that you create a System Restore point first.

Option 1 – Try to use the Registry Editor

If you have already upgraded from Windows 10 Home to Windows 10 Pro and you’re having trouble with its Activation, then you might want to apply some registry tweaks to fix the problem. How? Refer to these steps:

• Tap the Win + R key combination to open the Run dialog box.
• Then type “Regedit” in the field and click OK or tap Enter to open the Registry Editor.
• Next, navigate to this registry key: ComputerHKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersion
• From there, look for a DWORD named “EditionID” and once you found it, double click on it and change its Value data to Windows 10 Professional.
• After that, look for another DWORD named “ProductName” and double click on it to change its Value data to Windows 10 Professional.
• Once you’re done, restart your computer to apply the changes made successfully.

Option 2 – Try to use Command Prompt

If the registry tweaks you applied didn’t fix the Activation error, then you can try using Command Prompt instead. Note that you can use this option in both scenarios pointed out above.

• First, you have to insert a bootable drive of the Windows10 installer.
• Next, tap the Win + X keys and select Command Prompt (Admin) from the menu.
• After opening Command Prompt as admin, navigate to the root location of the bootable drive inside the Command Prompt command line.
• Once you’re already there, type the following command and tap Enter:

setup.exe /auto upgrade /pkey <YOUR WINDOWS 10 PRO EDITION PRODUCT KEY>

After entering the command, check if it was able to fix the Windows Upgrade or Activation error 0xc03f6506. If not, refer to the next given option below.

Option 3 – Try to disable the Network Adapter

Just like the second option, you can also use this option for both the given scenarios above.

• Tap the Win + X keys and select Network Connections from the menu.
• This will open the settings for your network and on the left side panel, click on the “Change adapter settings” link. This will open Control Panel.
• From there, click on the network your computer is connected to, and then right-click on the Network Adapter that you are using and select Disable.
• After disabling the Network Adapter, try to switch to the edition of your copy of Windows 10 again and see if the problem is now fixed and don’t forget to double click on the disabled Network Adapter to get back on the Network.
