There are cases where the power LED is visible but nothing appears on the screen,
There are also cases where the power LED itself does not turn on and nothing appears on the screen.
First, if you see the power LED but there is no response from the monitor
It could also be a problem with the monitor, the parts connected to the display, the adapter, or the wires.,
It could be a faulty memory.
Memory failures can sometimes be resolved simply by wiping them with an eraser.
If the power LED itself is off and the screen monitor shows no response,
This is a problem with the power adapter cable, or contact issues caused by the laptop's power adapter becoming loose,
It is a problem with the power-related components on the motherboard or the battery built into the laptop.
In the case of laptops, this is also a problem that often occurs in older laptops.
The solution is to replace the relevant part or adapter with a new one.
Batteries are consumables, so their performance deteriorates over time.,
Eventually, even when the power is turned on, the power LED does not light up, and the monitor does not display anything.
In this case, simply connect the laptop's power cable, and if the laptop works normally,
You can immediately identify the cause as a problem with the laptop's built-in battery.
