Description

Technical Field

[0001] This application relates to the field of power-on management technology in the field of ruggedized laptops, for example to a standby method for a laptop computer and a laptop computer. Background Technology

[0002] During the use of ruggedized laptops, laptops typically have a lid-open standby function. This function is usually implemented through a Hall sensor. A magnet is usually placed in the center above the display screen, and the Hall sensor circuit is placed below the keyboard and directly opposite the magnet. When the laptop is not closed, the Hall sensor circuit outputs a high level due to the pull-up resistor. When the laptop is closed, the Hall sensor contacts the magnet, pulling the signal low. The power management chip detects the low signal and puts the laptop into standby mode. However, in actual use and testing, it was found that the Hall sensor would occasionally pull the signal low for a period of time for no apparent reason, causing the laptop to enter standby mode.

[0003] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art.

[0005] This disclosure provides a standby method for a laptop computer, which uses radio frequency signals to enable the computer to enter a standby state, rather than simply using high or low voltage levels, thereby improving the stability of entering the standby state.

Specifically, an RFID card is placed at the end of the laptop's display, and a configuration circuit based on the RFID chip is placed below the laptop keyboard and directly opposite the RFID card. When the laptop is closed, the RFID chip can recognize the information on the RFID card.
