You can't. The RTC is a hardware device, and it's not reset when you reset the microcontroller. You can only reset the RTC by removing the battery or by using the reset pin on the RTC chip. But if you still want to preserve the RTC, you can use the RTC memory to store the current time, and then restore it after the reset. For example: Step 1: Reset The RTC. If the RTC has lost its timekeeping data, you may need to reset it. This can usually be done by setting the RTC’s time counter to a known value, such as the current time. RTC Reset Procedure. To reset the RTC, follow these steps: Connect to the device’s console or terminal.

FAQ How to Reset Embedded Controller (EC Reset), Real-Time Clock (RTC), and Hard Reset Applicable Products: Notebook, All-in-One PC, Gaming HandheldIf you are experiencing hardware or power-related issues with your laptop, All-in-One PC, or Gaming handheld, such as battery, keyboard, touchpad, or system startup problems, performing an EC reset (hard reset) and Real-Time Clock (RTC) reset might be one of the methods to resolve the issues. The EC is a chip on the motherboard that controls various hardware components and power management functions of the system. However, executing an EC reset (hard reset) and RTC reset can restore the hardware in your deviceto its default state. In this article, we will guide you on how to perform an EC reset (hard reset) and RTC reset.Here are the basic steps for an EC reset and RTC reset:Remove all external devicesTo avoid any possible interference, remove all external devices such as external hard drives, printers, memory cards, external ODD (if your computer is with internal ODD, remove CD/DVDs), and dongles, etc.Turn off the deviceMake sure you have saved all open files and then turn off the device.Connect the power adapterConnect the power adapter to the device.Press and hold the power button (Different models may have either a 20-second or 40-second press design)During the EC reset and RTC reset process, you need to press and hold the power button for 40 seconds. Make sure you have removed all external devices and connected the power adapter, and then press and hold the power button

Removing the RTC battery impacts the following: Real clock time gets reset to default value. CMOS setting of the server is lost. You should reset the system setting after replacing the RTC battery. The real-time clock (RTC) battery retains system settings when the server is disconnected from power. The battery type is CR2032. Cisco supports the industry-standard CR2032 battery, which can be purchased from most electronic stores. Procedure Step 1 Remove the RTC battery: Shut down and remove power from the server as described in Shutting Down and Removing Power From the Server. Slide the server out the front of the rack far enough so that you can remove the top cover. You might have to detach cables from the rear panel to provide clearance. Caution If you cannot safely view and access the component, remove the server from the rack. Remove the top cover from the server as described in Removing the Server Top Cover. Locate the RTC battery. The vertical socket is directly in front of PCIe riser 2. Remove the battery from the socket on the motherboard. Gently pry the securing clip on one side open to provide clearance, then lift straight up on the battery. Step 2 Install a new RTC battery: Insert the battery into its holder and press down until it clicks in place under the clip. Note The flat, positive side of the battery marked “3V+” should face left as you face the server front. Replace the top cover to the server. Replace the server in the rack, replace cables, and then fully power on the server by pressing the Power button. Figure 27.

A blue "Automatic Repair" or "Recovery" screen.However, if the screen remains stuck on the black screen with "Preparing Automatic Repair" for an extended period, you can try the following solutions:Solution 1: Remove External Devices and RestartTurn off the device. Press and hold the power button until the power light goes off to shut down the device.Remove all external devices, including the keyboard, mouse, external hard drive, printer, memory cards, CDs in the optical drive, and any adapter cards in card readers. Sometimes, external devices can prevent your device from entering the repair screen.Note: Also, disconnect all external displays. If it's a desktop computer, start with one external display to verify that your computer can boot and display properly.After removing the connected devices, power on the device and check if this resolves your issue. If not, proceed to the next solution.Solution 2: Force Shutdown and Perform CMOS ResetAttempt a force shutdown. Press and hold the power button until the power light goes off to shut down the device.Perform an Embedded Controller (EC Reset) or Real-Time Clock (RTC) reset to restore the hardware in your device to its default state. You can refer to the following articles to understand how to clear it:For Notebook/All-in-One PC/Gaming Handheld: How to Reset Embedded Controller (EC Reset), Real-Time Clock (RTC), and Hard ResetFor Desktop: How to clear CMOS If your device can boot into Windows after the restart, make sure to update the BIOS, Windows updates, and drivers to their latest versions to prevent future issues..
