Fix Broadcom BCM20702A0 driver error

In recent times, some Windows 10 users have seen an error code BCM20702A0, when using Bluetooth and they are concerned as to what it is all about. We can say for certain that it has something to do with your Bluetooth driver. The error message in question is:

The drivers for this device are not installed. There are no compatible drivers for this device.

The problem here tends to no longer allow specific Bluetooth components to properly communicate with your Windows 10 operating system. It also affects laptops that do not have native Bluetooth support; therefore, the manufacturer installed a dongle on the inside to deliver the service. This is not the best way to do things because native support is always better. On the other hand, maybe you’re using a Broadcom USB Bluetooth dongle that is acting up, and as such, the error is showing.

Below are solutions provided for this particular error and how to eliminate it.

  1. Run the Bluetooth Troubleshooter

    Press ⊞ WINDOWS to open the menu and select settings
    In settings choose Update & Security
    Go to troubleshoot and on the right panel click on additional troubleshooters
    Click on Bluetooth
    Select Run the troubleshooter, then sit back and allow the tool to do its thing. Once you’ve completed the task, click on Apply this fix if any repairs are needed
    Reboot your computer

  2. Install Broadcom driver from official website

    Windows drivers for Broadcom Bluetooth devices are no longer posted on their website. They should be available through Microsoft’s Windows Update service. If drivers were not downloaded automatically by Windows Update, use Device Manager to refresh the driver from Windows Update.
    However, the Broadcom Bluetooth drivers seem to be available here on the Lenovo website. To fix the BCM20702A0 driver error, you may download and install them.
    After downloading it, right-click on the downloaded item, and select Run as administrator. After installation, restart your computer, then check again if it works.

  3. Remove all Bluetooth drivers and USB controllers

    If previous solutions did not work, go to device manager and remove all Bluetooth devices along with all USB controllers.
    Reboot your computer and Windows will automatically reinstall and set all devices.

Fix “Diskpart failed to clear disk attributes”
If you encounter the “Diskpart failed to clear disk attributes” error when you try to change the read-only state of a storage device using the Diskpart application and the request is denied, worry not for this post will give you a couple of fixes to resolve the problem. As you know, Diskpart is used for resolving read-only storage devices by changing their attribute via the command line. So if it is not able to change the attribute of the storage device, then you will most likely encounter an error such as this one. This kind of error is not uncommon and as long as there are no damaged physical attributes, you can resolve it right away. There are tons of reasons why you’re getting this error while using Diskpart, it could be that the storage device has a physical write-protected switch or the disk is hidden or has bad sectors. It could also be because the storage drive might be in RAW format or that you are running the Diskpart application without admin privileges. Whatever the cause may be, here are some options you can try to fix the problem but before you proceed, make sure that you log on to your PC as an administrator.

Option 1 – Check if there is a physical switch on the storage device

There are some USB devices and SD card readers that have a write-protected physical switch that disables all the writable options on the storage device and so if it is turned on, Diskpart won’t be able to change the disk attribute to writable. To check, simply look for the physical switch on both sides of the device and once you found it, make sure that it is toggled off and then plug the storage device back in then try running Diskpart once again.

Option 2 – Modify the WriteProtected key in the Registry Editor

Before you proceed, you have to create a System Restore Point first.
  • Tap the Win + R keys to open Run and type “Regedit” in the field and hit Enter to open the Registry Editor.
  • Next, navigate to the following path:
HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlStorageDevicePolicies
  • After that, look for the “WriteProtect” registry entry which is located on the left side of the window, and then double click on it.
  • Change its value to “0” and click OK to save the changes made and exit the Registry Editor.

Option 3 – Run CHKDSK to check the drive for errors

When it comes to some issues concerning the hard drive or removable devices, there is a utility in Windows that might help which is called “chkdsk”. This error check utility can help with several issues in the system including the “Diskpart failed to clear disk attributes” error.
  • Tap the Win + S keys to open the Search box.
  • Then type “command prompt” in the field and from the search results that appear, right-click on Command Prompt and select “Run as administrator”.
  • After opening an elevated command prompt, copy and paste the following command and hit Enter:
CHKDSK [volume [[path] filename]] [/F] [/V] [/R] [/X] [/C] [: size]]
Note: In the command given above, “[/F]” will try to fix the system errors while “[/R]” will be the one to fix the bad sectors.
  • Now if you are prompted to run CHKDSK after your reboot your PC, just tap Y and reboot your PC.
  • If CHKDSK is not able to find any errors, tap the Win + E keys and navigate the access window. From there, right-click on the concerned drive and click on Properties.
  • After opening Properties, click on the tab Tools and then click on the “Check” button under the Error-checking section.
  • Wait until the process is completed and then restart your computer.

Option 4 – Clear the attributes on RAW

  • Tap the Win + S keys then type “diskpart” in the field.
  • Click the Diskpart application and if a User Account Control dialog box pops up, click Yes to proceed.
  • After opening an elevated Command Prompt, type in the commands listed below and make sure to tap Enter right after you key in one command after the other.
    • list volume
    • select volume ‘n’ (In this command, you have to replace ‘n’ with the volume number of the drive)
    • format fs=fat32 quick (In this command you also have the flexibility to change the format to ‘ntfs’ or ‘exfat’)
  • After executing the commands given, unplug the removable storage device and wait for a couple of seconds and then plug it back in.
  • Now try any normal write operations and see if the error no longer appears.

Option 5 – Try checking the hardware components

On the other hand, it is also possible that the issue has something to do with a hardware problem and so you need to check the hardware components on your computer to determine that.

KVM switch and its usage

You probably heard about switches for LAN but not a lot of people heard about KVM switches. So what exactly is KVM switch?

KVM switch

If we look at the name, it is a shortcut for Keyboard, Video & Mouse and the original idea was to have multiple computers but one keyboard, mouse, and monitor. These peripherals would be connected to the KVM switch and other computers could all use one set of these on the fly when needed.

The technology behind the switch is a little interesting since it will actively fake signals to other computers that are not using peripherals. Once they are switched to them the transition is smooth and not noticeable. In old days these switches were more important than today since on every mouse or keyboard disconnection you had to reboot the computer, and although today that is not the case CPU will still detect disconnection and on the next connection it will run through the ID of the device and try to use the existing driver and if peripheral was connected in other USB port, it will install the same driver but connect it to the new USB port.

This type of reconnection can slow down work and place unnecessary load on the CPU so that is why KVM will fake connection in order to make switching externals on the computer smooth and in nick of a time.

Modern KVM switch

These days modern KVM switches will offer you more options than just being able to switch between keyboard, mouse, and monitor. Modern switches now offer Lan, audio, and many more various options.

There are also different kinds of switches offering you only one option, like for example just a Video switch that will let you use one monitor on three computers and many more other specialized options.

Software switches

So far we talked about Hardware switches, a real device being able to take peripherals into it and switch computers on the fly. On the other line, we have software switch solutions that will have specific software installed on all computers and have it run at all times, and switching between them will be through specific software.

There are two very good and main advantages of using software solutions instead of a hardware one. First, of course, is the price, since the most popular Synergy is an open-source solution, completely free of charge. The second big advantage is that software switch is not limited to how many computers can you use. Hardware switches tend to go to a large number like 16 but if you have a large cluster of computers over a LAN, let's say 30 then the box solution might be difficult.

On the other hand software solution will switch only keyboard and mouse since each other computer will have to have some screen on it in order to work. Both solutions have their strong advantages and disadvantages and it is up to you to choose one that best suits you.

Conclusion

If you are multitasking with a lot of computers or just need your peripherals from time to time to connect to another machine then the KVM switch is something that you might find the use of. Just be aware that if you go for some cheap switch you might experience some lag on your peripherals, but if that is not a concern you can get hardware one for as low as $50 USD.

New focus sessions in Windows 11
focus sessionWindows and Devices chief Panos Panay has revealed new focus sessions feature that will be in Windows 11 on his Twitter account today. He himself is referring to it as a game-changer especially with Spotify integration.

So what is a focus session?

From the video clip provided on Twitter, we can see that focus session users will be able to choose a specific task from the previously made task list, choose songs that will play in the background while the task is active, and set a timer for the chosen task with breaks. Maybe the best comparison and explanation would be a desktop google calendar task with music, basically, that’s it. A neat and good organizer inside your Windows 11 operating system. I think that this is generally a good idea and for sure it will find its audience.

How to Fix Low Wi-Fi signal strength on Windows 10
If you are experiencing a Low Wi-Fi signal strength on your Windows 10 PC after you’ve updated or reinstalled it, read on as this post will guide you on what you can do to fix the problem. The way devices connect these days has evolved with our cognitive revolution. Various devices use some or other wireless technology to connect with other devices. However, all wireless technology has some kind of limitation when it comes to range and signal strength. From time to time, you might have faced several Wi-Fi issues. Low Wi-Fi signal strength usually happens after you update or reinstall your Windows 10 system. This issue can be identified easily by looking at the signal bars in the Wi-Fi icon or by measuring its strength. Since this problem is wide scope, there are tons of possibilities which is why this post covers the most generic situations that could help most users. Refer to the options given below to fix the low Wi-Fi signal strength of your Windows 10 PC.

Option 1 – Try running the Network Adapter Troubleshooter

If a few days ago the range and signal of the Wi-Fi was perfectly fine before you did an update or reinstall, it is possible that there were some changes made in the configuration as well. In most cases, the latest configuration that came with the update has not aligned the config in your computer or laptop. The easiest and simplest way to fix this is by using the Network Adapter Troubleshooter. How? Follow the steps below.
  • Right-click on the Wi-Fi icon from the system tray to start troubleshooting.
  • After that, select Troubleshoot problems. Note that it might take a while to run it but once it’s finished, it will show you all the problems with the network adapter.
Note: The Network Adapter Troubleshooter will also fix the issues in the background but there might be some issues that will require manual action. And if the troubleshooter wasn’t able to identify and fix the problem for you, proceed to the next given option below.

Option 2 – Try using the Device Manager

If the problem is related to hardware, you need to seek out the help of the Device Manager. To do so, follow the steps below.
  • Pull up the Device Manager.
  • Next, look for your Wi-Fi adapter under the Network Adapters.
  • Once you found it, right-click on it and open Properties.
  • After that, you will see all the actions related to drivers under the driver tab.
  • You can either update or roll back the selected driver or you could also disable and re-enable it to see if the problem’s fixed.
Note: If updating the driver didn’t help, you might have to dig into the advanced settings. From this post on, it can get a bit complicated as there are terms that you might not understand as well as some configuration. To make it easier for you, you can search for your Wi-Fi adapter online and try following the instructions from there. And before you make any further changes to your computer’s settings, make sure that you create a system restore point first.

Option 3 – Try changing the Wi-Fi Roaming Sensitivity

If you want to enhance the Wi-Fi reception as well as the performance on your Windows 10 PC, you might want to change the Wi-Fi Roaming Sensitivity or Aggressiveness. Roaming Sensitivity is the rate at which your computer chooses and switches to the nearest available point of access which offers a better signal. It is based on the strength and quality of the Wi-Fi and not on the distance to the Wi-Fi point.

Option 4 – Try adjusting the Wi-Fi range

The issue could also be caused by the position of your computer with respect to the Wi-Fi router instead of your hardware or drivers. It could be that your physical location might be a factor for the low signal strength of your Wi-Fi so you might want to adjust the Wi-Fi range to fix the problem.

Configure Windows 10 to create Dump Files on Blue Screen of Death
If your Windows PC encounters an error, it will display a Blue Screen of Death or BSOD error which usually comes up for a fraction of second and creates some logs or Dumps Files as what other user prefers to call it and then boots your PC suddenly. This process usually takes place quickly that most users find it hard to get the error code and won’t probably be able to check what really went wrong with their PCs. This is where the dump files come in. They are stored internally in your computer and can only be accessed by an administrator. They are classified into 4 main types and in Windows 10 they are either:
  1. Complete Memory Dump
  2. Kernel Memory Dump
  3. Small Memory Dump (256 KB)
  4. Active Memory Dumps
Dump Files are useful as they could help you in resolving the problem and so you need to configure your Windows 10 PC to create them but first, you need to make a system restore point. This is essential as you are about to modify some system files as well as critical Windows 10 settings. There are two ways you can create Dump files – first is by modifying the settings in the Startup and Recovery and lastly is via the WMIC command line. Refer to the instructions prepared below to be guided on how you can create Dump files after any BSOD error using these options.

Option 1 – via Startup and Recovery

  • Type in “control panel” in the Cortana Search box and then click on Control Panel from the search results to open it.
  • After opening Control Panel, you need to make sure that you view the contents by their Category then click on the header link which is labeled “System and Security” or you could also right-click on the This PC icon and then click on Properties.
  • Next, select the Advanced system settings from the left panel. Once you do, a new and small window will pop up.
  • Under the newly opened window, look for the section called Startup and Recovery and then click on the Settings button.
  • And from the System Failure section, you can choose any option from the drop-down for Write debugging information such as:
    • None – this means that there is no dump file created by Windows
    • Small Memory Dump – this means that Windows will create a Minidump file on BSOD
    • Complete Memory Dump – this means that Windows will create a Complete Memory Dump file on BSOD
    • Automatic Memory Dump – this means that Windows will create an Automatic Memory Dump file on BSOD
    • Active Memory Dump – this means that Windows will create an Active Memory Dump file on BSOD
Note: The complete dump needs a page file that is allowed to be the size of the physical memory installed in your PC with a dedicated 1 MB of space for just the page header.
  • Now once you have selected the most suitable option for you, just click on OK/Apply and then exit.
  • Restart your PC to successfully apply the changes made.

Option 2 – via the WMIC command line

  • The first thing you need to do to create Dump files via the WMIC command line is to tap the Win + X keys combination or simply right-click on the Start button and then select the Command Prompt (Admin) option. You could also type in “cmd” in the Cortana search box and then right-click on Command Prompt from the results and select Run as administrator.
  • After that, type in any of the commands given below depending on your preferences so that your Windows 10 PC will be configured to create Dump Files:
    • No dump file: wmic RECOVEROS set DebugInfoType = 0
    • Small Memory Dump: wmic RECOVEROS set DebugInfoType = 3
    • Kernel Memory Dump: wmic RECOVEROS set DebugInfoType = 2
    • Complete Memory Dump: wmic RECOVEROS set DebugInfoType = 1
    • Automatic Memory Dump: wmic RECOVEROS set DebugInfoType = 7
    • Active Memory Dump: wmic RECOVEROS set DebugInfoType = 1
Note: A complete dump has to have a Page file which is allowed to be the size of the physical memory installed on your PC accompanied by a 1 MB space for just the page header.
  • Now type in “exit” in the Command Prompt to exit it.
  • Restart your PC to apply the changes made successfully.
