How To Turn On A Laptop Without Power Button?
When your laptop’s power button becomes unresponsive or broken this forces you to turn on and off the laptop using other methods such as pushing the laptop into sleep mode and then waking it up.
You can also use a Windows operating system shortcut that triggers your computer to wake from sleep mode automatically when you press a specific key combination.
If none of these options works for you try using an external power source such as a battery pack or a universal charger adapter.
When all else fails there is one final way to turn on your laptop without having access to its power button: by removing its BIOS battery.
This will trigger the motherboard to send a signal to the computer’s boot device every time it powers up while replacing the motherboard’s lithium-ion battery.
Note: Removing the motherboard’s BIOS battery will clear your laptop’s BIOS settings which means you will need to reset them after replacing the battery.
You can use an external device such as a USB flash drive or an optical disc to back up important files on your computer before replacing the BIOS battery.
