The notebook will ring twice when it is turned on, and the prompt is as follows! !

Under normal circumstances, there are several long tones, short tones or long and short tones when the system is turned on, which are all system alarms. There should be no five short tones when the notebook is turned on, which makes sense. Personally, it's probably a bios setup problem. When the system restarts, the system can't find any hardware in the machine, so it calls the police or something.
