How to solve the computer not turning on

Step 1: Check Power Supply

  • Make sure the power cord is securely plugged into both the power outlet and the computer’s power supply unit.
  • Ensure the power outlet is working by plugging in another device.
  • Try a different power cord if available.

Step 2: Inspect Power Button and Connections

  • Verify that the power button on the computer is not stuck or damaged.
  • If using a desktop, check the connection between the power button and the motherboard. Ensure it’s securely connected.

Step 3: Test the Power Supply

  • If you have a desktop PC, you can test the power supply unit (PSU) by using a PSU tester or swapping it with a known working PSU.
  • For laptops, if the battery is removable, try removing it and then plugging in the power cord to see if the laptop powers on.

Step 4: Check Internal Components

  • Open the computer case (if it’s a desktop) and ensure all internal components such as RAM, graphics card, and cables are properly seated.
  • Reseat the RAM sticks and any other removable components.

Step 5: Clear CMOS (BIOS)

  • If the computer has power but fails to boot, clearing the CMOS settings might help. Refer to your motherboard’s manual for instructions on how to do this.

Step 6: Check for Signs of Damage

  • Inspect the motherboard and other components for any signs of physical damage such as burn marks, bulging capacitors, or loose connections.

Step 7: Test with Minimal Hardware

  • Disconnect all non-essential hardware components (such as additional drives, expansion cards) and peripherals.
  • Try booting the computer with only the essential components (CPU, RAM, motherboard, power supply) connected.

How to whitelist particular domains in Office 365

To whitelist a domain in Office 365, users must

  1. Click on the “Admin” drop-down box found on the top of the display
  2. Click on “Exchange” and click the “Mail-Flow” heading
  3. Select “Bypass spam filtering” on the menu after clicking on the plus icon

  5. From the “Apply this rule if” drop-down box, choose “The Sender domain is”
  6. Enter the domain that should be whitelisted. The whole email address should not be included, only the domain such as xyz.com or gmail.com
  7. Click “Ok”
  8. Check the “Stop Processing More Rules” Option and click Save

Along with the whitelist feature, Microsoft offers various other Office 365 spam filter advanced options that allow users to configure and manage their anti-spam settings. These include choices that “increase spam score” if characteristics such as Linked images, Numeric IP addresses, URL to .biz sites, and so on are found in the email. There are also options to mark some emails, such as empty emails or those that have JavaScript as spam.

Some Office 365 spam filter best practices to get the best out of the service include

  • Set-up multi-factor authentication (MFA) on all accounts.
  • Set up Advanced Threat Protection (ATP) for all Office 365 mailboxes.
  • Users must be educated to flag phishing emails to train the system. Suspicious emails should be marked as junk.
  • Add warnings when external emails from outside the organization arrive.
  • To combat phishing, set up rules for blocking or warning about emails that seem to be similar to a user’s domain but are not from it.
  • For enhanced detection, enable the auditing and logging of user activities in all areas possible.
  • Dedicated spam filtering and secure messaging solutions can be implemented for advanced protection.
  • Follow the Principle of Least Privilege.

Office 365 is an excellent cloud-based platform that fulfills all requirements of enterprises. It has several features that make it right for users. For instance, for preventing outbound spam office 365 has built-in filters. Such spam filters in Office 365 should be leveraged to their full extent, and best practices should be followed to ensure that spam emails do not interfere with the operations of an enterprise. Although the Office 365 spam filter is handy, it can block legitimate email communications. Setting up the Office 365 Spam Filter Whitelist is the best solution to allow desired messages to pass through the filter.

How to fix Windows Backup Error 0x8078012D

Windows users have reported seeing an error code 0x8078012D when they attempt to create a backup of the Windows Installation using the Windows Backup Utility. This issue is reported to have occurred in Windows 7, Windows 8, and Windows 10.

Usually, this error may be triggered due to any of the following reasons:

1. Disabled Windows Backup Service

2. Corrupted Storage Sectors

3. System File Corruption

4. Third-party software Conflict

Now that we know the possible causes for the error, let us see the fixes that other affected users have tried to resolve the issue.

Fix 1 – Enable the Windows Backup Service

1. Press Windows key + R to open the Run dialog. Open Services screen by typing services.msc in the Run box. If you are prompted by UAC (User Account Control), click on Yes to grant access.

2. Inside Services, on the right side, scroll through the list of services until you find an entry associated with Windows Backup.

3. Right-click on Windows Backup and select Properties in the context menu.

4. In the Properties screen,  select the General tab and change the Startup type to Automatic, then click on Start to start the service if it is stopped.

5. Apply the changes. Restart the system and repeat the action causing the 0x8078012D error code to check if it is resolved.

Fix 2 – Run a CHKDSK scan

If the above fix did not work, then you need to investigate whether it is an HDD/SSD storage-related problem. A CHKDSK (Check Disk) scan allows to identify malfunctioning logical sectors and replace them.

1. Press Windows key + X to open the WinX menu.

2. Click on Windows PowerShell (Admin) in the menu to launch the PowerShell with administrative privileges. If you see a UAC dialog, click on Yes to continue.

3. In the PowerShell window, type chkdsk X: where X is the drive letter corresponding to the partition of your system hard drive that you want to scan, followed by the parameters you want to perform the scan with, and then press Enter. Running a scan without the parameters will result in only scanning the selected drive and it will not fix the errors found.

The following parameters can be used :

/f - Tells CHKDSK to fix any and all errors that it finds
/r - Tells CHKDSK to locate bad sectors on the drive and try to recover any and all readable information from them
/x - Tells CHKDSK to forcefully dismount the selected drive before scanning it

The final command will look as below:
chkdsk C: /f
or
chkdsk D: /f /x

4. Wait for CHKDSK utility to finish its work. At the time of the scan, you will be able to continuously monitor the utility’s progress.
Fix 3 – Run SFC and DISM scans

System File Checker (SFC) and Deployment Image Servicing and Management (DISM) are two built-in tools that are equipped to fix the most common corruption issues that might trigger the 0x8078012D error with Windows Backup.

SFC is a local tool that doesn’t require an internet connection as it uses the locally stored cache to replace corrupted system files whereas DISM requires an active internet connection as it uses a component of Windows Update to replace corrupted windows file instances downloaded over the Internet.

Click on How to perform SFC and DISM scans to fix the issue. Move to the next fix if this doesn’t resolve your error.

Fix 4 – Disable or uninstall 3rd party security suite

In case you are using a 3rd party security suite or firewall, it’s possible that a false positive is affecting the backup and triggering the error. You can probably avoid the error code while creating a backup by disabling the security suite before opening Windows Backup.

1. Right-click on the tray icon of your 3rd party antivirus and look for an option that allows disabling real-time protection.

2. If disabling was not enough to fix the issue, then uninstall the 3rd party security suite from the Programs and Features menu.

Note:

If you are using Windows Defender, skip this method as there is no evidence that it conflicts with the backup service.

Fix 5 – Restart PC in Clean Boot Mode

If the above fixes did not work, there may be a specific application that is triggering this error. To debug this, click on Clean Boot PC in Windows 10 to boot your system in clean boot mode and determine if a specific application is causing the error.
