Set up time on Xiaomi RedmiBook 8 Pro: synchronization, manual input and troubleshooting

Incorrectly configured time on Xiaomi RedmiBook 8 Pro can lead to app crashes, file synchronization problems, and even authentication system errors. This is especially critical for enterprise users, where a time difference of a few minutes can block access to email or cloud services. In this article, we will discuss all the ways to adjust time, from automatic synchronization through the Internet. NTP-servers before manual input, taking into account time zones.

Many users find that after a Windows update or a BIOS reset, the clock on a laptop begins to lag behind or show an incorrect time zone, the reasons can be different from a dead CMOS battery to conflicts with an antivirus that blocks access to time servers, we will analyze each scenario in detail and give specific recommendations for fixing problems.

Unlike smartphones, where time is usually synchronized automatically over a mobile network, on RedmiBook laptops, this process depends on the settings of the operating system and hardware components. If you notice that the date or time is lost after each shutdown, this is a direct signal of a malfunction of the RTC (Real-Time Clock) chip, which is powered by a separate battery on the motherboard.

1. Automatic time synchronization through Windows

The easiest and most recommended way is to use the built-in time synchronization feature in Windows 10/11. The system automatically connects to time.windows.com servers and adjusts local time to your time zone. Here's how to configure it:

Open Settings → Time and Language → Date and Time. In the Synchronization block, turn on the switches:

1. Set time automatically – allows the system to receive data from NTP-server.
2. Automatically set time zone – determines your location by geodata or IP.

Is the setting "Set time automatically" activated?

Is the correct time zone manually selected (if the automation is not working)?

Is there internet access (check the connection)?

If you still get lost after turning on these options, try manually running synchronization:

1. Press Win + R, enter w32tm /resync and confirm execution.
2. For forced re-registration of the time service, use the command: w32tm /register

⚠️ Note: If an error occurs after the commands are executed 0x80070005, This means that your account does not have administrator rights.

2 Manual change of date and time

In cases where automatic synchronization is not available (for example, if there is no Internet connection), you can set the time manually.

1. Open the settings → Time and language → Date and time.
2. Turn off the option "Set time automatically".
3. Click "Change" under the "Set date and time manually" block.

In the window that opens, select:

• 📅 Date - enter the current date in the format DD.MM.GYYY.
• ⏰ Time – Set the hours and minutes to the right of a second (important for some financial applications).
• 🌍 Time zone – select your region from the drop-down list (e.g, (UTC+03:00) Moscow, St. Petersburg).

💡

If you travel frequently, add a time zone widget to the taskbar: Settings → Personalization → Taskbar → Enable the clock for multiple time zones.

After manual adjustment, the time will be saved until the next failure, but remember: without synchronization through NTP, the clock will gradually “go away” due to the inaccuracy of the quartz generator in the RTC chip.

3. Checking and replacing the CMOS battery

If time is lost every time you turn off your laptop (not restart!), the problem is a dead CMOS battery (or RTC battery), a little pill on the motherboard that powers a real-time chip when the laptop is offline, with a lifespan of 3 to 5 years, and then needs to be replaced.

To check the status of the battery:

1. Turn off the RedmiBook 8 Pro and disconnect the charger.
2. Turn over the laptop and remove the bottom cover (a cross screwdriver will be required).
3. Find the CR2032 battery (usually located next to the RAM slot).
4. Measure the voltage with a multimeter - it should not be lower than 2.8 V.

To replace:

• 🛠️ Carefully remove the old battery by smacking it with a plastic spatula.
• 🔋 Install a new one. CR2032 (cost ~100-150 rubles), observing polarity (+ upward).
• 🔧 Build a laptop and turn it on – time and settings BIOS They will fall, they will have to be re-configured.

⚠️ Note: After replacing the battery, be sure to check the boot settings in BIOS (keyboard F2 Incorrect settings can lead to a cyclical reboot of the system.

4. time setting via BIOS/UFI

In some cases (for example, after a BIOS reset or firmware update), system time may be lost due to incorrect hardware-level settings.

1. Restart your laptop and go to the BIOS by pressing F2 (or Del, depending on the version).
2. Go to Main or System Time/Date.
3. Set the correct date and time with the +/- keys.
4. Save the changes (F10) and exit.

If the BIOS time is lost immediately after the release, this confirms the malfunction of the CMOS battery (see section 3).

• 🔄 Legacy Support settings – if compatibility with legacy OS is enabled, it can affect the work RTC.
• ⚡ Parameter ACPI Settings – Must be Enabled for proper synchronization with Windows.

5. Solving synchronization problems

If the time on RedmiBook 8 Pro is persistently out of sync, the reasons may be as follows:

To diagnose the time service in Windows:

1. Open the Command Prompt (Administrator).
2. Execute the command: w32tm /query /status
3. Check the lines: Source - the server must be specified (e.g. time.windows.com) Last Successful Sync Time - the date of the last successful synchronization.

💡

If the time service status is Source: Local CMOS Clock, it means that synchronization with external servers is not working.

6. Alternative Time Servers

Windows uses time.windows.com by default, but it can sometimes be overloaded or blocked by the provider. NTP-server:

• 🌍 pool.ntp.org – a global pool of servers with automatic load balancing.
• 🇷🇺 ntp1.stratum2.ru — Russian server (suitable for users with high accuracy requirements).
• 🇺🇸 time.google.com – Google server with minimal latency.

To change the server:

1. Open the Command Prompt (Administrator).
2. Run the command (e.g. for Google): w32tm /config /syncfromflags:manual /manualpeerlist: "time.google.com"
3. Reset the time service: net stop w32time & net start w32time

After changing the server, force the synchronization:

w32tm /resync /force

7.The Impact of Antiviruses and Firewalls

Some antivirus programs (such as Kaspersky Internet Security or Avast) block access to the Internet. NTP-If the time synchronizes normally after the antivirus is disabled, add an exception to the service. w32time.exe.

For Windows Firewall:

1. Open Control Panel → Windows Firewall → Additional settings.
2. Go to the Rules for outbound connection.
3. Find the Windows Time rule (NTP-UDP-Out) and make sure it’s enabled.

⚠️ Attention: If you are using VPN, It can replace your real time zone. VPN Before setting the time or manually specify the correct region.
