Adjust computer startup time

BIOS is the basic input/output system in a computer, which manages communication between computer hardware and software. When the computer starts up, the BIOS is first loaded and run, then hands over control to the operating system.

In the BIOS settings, an interesting function is to set the boot time. The boot time refers to automatically starting the computer at a specified time point. This is useful for users who need to start work at a specific time, such as when at the office or school, and can automatically start their computer a few minutes before arrival.

To set the boot time, we need to enter the computer's BIOS setting interface. Each computer's BIOS setup interface may be slightly different, but the general steps are similar. The following is a general example:

1. Turn on the computer and press the specified key (usually the DEL key, F2 key or ESC key) when booting to enter the BIOS setup interface. Screens displayed during startup usually provide appropriate prompts.
2. After entering the BIOS setup interface, use the arrow keys on the keyboard to move to "Power" or similar options. This option may vary between BIOS versions.
3. In the "Power" options, look for "Power On By RTC Alarm" or similar option. RTC stands for real-time clock, which is used in the BIOS to track time.
4. Enable the "Power On By RTC Alarm" option. In this way, we can set the boot time.
5. After enabling the "Power On By RTC Alarm" option, a new option will usually appear so that we can set the date and time for power on.
6. Use the arrow keys and Enter key to set the date and time to the point in time you want the computer to start automatically.
7. After completing the settings, press Save and Exit (usually the F10 key), and then restart the computer.

From now on, when the set date and time arrives, the computer will automatically start and start your work.

It should be noted that computers of different brands and models may have different BIOS setting interfaces and option names. If the above steps cannot solve the problem, we can refer to the computer user manual or consult relevant technical support.

To summarize, we can easily set the computer boot time through BIOS settings. This feature is very convenient for users who need to automatically start their computer at a specific point in time. Whether in the office, school or other occasions, we can make full use of this feature to make the computer always available to us.
