Specifically, 5 blinks indicate a General System Board failure. Here are a few steps you can try to troubleshoot the issue: Disconnect all peripherals, such as external hard drives, printers, and USB devices. Then, turn off the laptop, remove the battery and unplug it from the power source.
If the problem is not solved, test with another adapter.
Check the motherboard in terms of connection. You can do this with diode check.
If the device has discrete graphics, convert it to Intel graphics.
