點解我開拖把上面個制,未按電腦開關制,部機自己識開(20分)

Need to change BIOS setting in Power OptionsBe very careful to follow the steps below as any mistake will change or even stop your computer from working properlyReason: A line signal off your internet connection turns PC on if Wake up on LAN is enabled in BIOS of your motherboard
Shut down computer then wait 5 minutes and turn it back on.Press the Del key once every second after boot up until a blue screen (BIOS) appears then stop.Use the left/right arrow keys on keyboard to move around the BIOS tabs (pages) and look for Wake up on LAN in Power Options . Sometimes it might be in the Advanced tab. Navigate around those tabs to find it. When found, see if Wake Up On LAN is Enabled. If so, use arrow keys to highlight those words then press either PageUp or PageDown key to Disable it. Now press Esc to quit out of tabs. Press F-10 key then select Save and Exit. BIOS will close and reboot your computer as usual.
Remember: Do this slowly. Always read on screen instructions before making any changes as mistakes can cause serious trouble to your computer. If procedure above fails or BIOS needs no change, unplug your internet/phone line when computer is not in use.

可以在BIOS設定,去BIOS的電源管理選項,
會有Restore AC Power Loss, 如果設定為Enabled,當有電源時就會自動開啓電腦.

請更改為Disabled.

想知更多電腦知識,系統電腦教育中心課程幫到你

可能你電腦上嘅開機制卡住,所以一有電源便會自動開機


建議:用手摸下開機制(有冇凹入去,如有推番出黎就無事)
