Time Synch Problems Acer Laptop A315-24PT and Windows 11, version 25H2

It seems that your Acer A315-24PT laptop is having issues synchronizing time, as indicated by the output of the w32tm /query /status command showing that it is not synchronized and referencing the local CMOS clock. Here are some steps you can try to resolve this issue:

1. Check Windows Time Service: Ensure that the Windows Time service is running. You can do this by executing the following commands in an elevated Command Prompt:

      net start w32time
   

2. Force Resynchronization: You can force the time service to resynchronize by running the following commands:

      w32tm /resync /force
   

3. Clear W32Time Registry Values: If the above steps do not work, you may need to clear the W32Time registry values. Run the following commands:

      net stop w32time
      w32tm.exe /unregister
      w32tm.exe /register
      net start w32time
      w32tm.exe /resync /force
   

4. Check NTP Configuration: Ensure that your NTP settings are correct. You can check the current configuration by running:

      w32tm /query /configuration
   

   Make sure that the NTP server is set correctly.
5. Reconnect to the Internet: Sometimes, simply reconnecting to the internet can resolve synchronization issues, especially if the computer needs to access external time servers.
6. Disable Secure Time Seeding: If none of the above methods work, you can try disabling Secure Time Seeding as a last resort. Run the following command:

      reg add HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\Config /v UtilizeSslTimeData /t REG_DWORD /d 0 /f
   

   Then restart your computer and run the resync command again.

After trying these steps, check the synchronization status again using w32tm /query /status. If the problem persists, there may be a deeper issue with your system settings or hardware that may require further investigation.

Hi SacBat,

Welcome to Microsoft Q&A!

I'm sorry to hear that you're having a time sync problem with the newly bought Acer. From your logs, this likely points to configuration issues with the time source or service registration. rather than network connectivity (since UDP 123 works). Here's what you should try:

1 - Perform a clean reset of the Windows Time Service

• Open Command Prompt as Administrator > run these commands one by one:
  • net stop w32time
  • w32tm /unregister
  • sc config w32time start= disabled
• Restart your Acer and open Command Prompt again, now run these:
  • sc config w32time start= auto
  • w32tm /register
  • net start w32time
• Set NTP configuration with the correct flags by entering: w32tm /config /syncfromflags:manual /manualpeerlist:"pool.ntp.org,0x1 time.windows.com,0x1" /reliable:yes /update
• Then force an immediate sync and verify time:
  • w32tm /resync /force
  • w32tm /query /status

2 - If it still shows Local CMOS Clock

• Press Win + R > enter services.msc > find and double-click Windows Time
• In Dependencies tab, ensure Remote Procedure Call (RPC) or similar is Running
• Then press Win + R > enter regedit to open Registry Editor
• Navigate to: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\
• Find (create if needed) and right-click the W32Time folder > Permissions...
• Click Advanced > Set the Owner to TrustedInstaller
• Also give SYSTEM and Administrators Full Control

Disclaimer: Generally, modifying registry subkeys or work group is intended for advanced users, administrators, and IT Professionals. It can help fix some problems, however, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For further protection, first check out How to back up and restore the registry in Windows - Microsoft Support 

3 - Check firmware if the problem still persists

• Enter your Acer BIOS (often by pressing F2 during boot)
• Make sure the system Time & Date is correct, reset if needed.
• Look for and disable Wake on LAN / PCI Power Management if found.
• Save, exit, and boot into Windows. Test the time sync again.

If nothing works, your Acer likely has a firmware bug that requires a BIOS update, or a pre-shipped issue. Try downloading the latest package from Acer's website, as well as consider requesting replacement from the seller. This is the most probable solution for brand-new hardware, especially if you're still under warranty.
