My device have power but don't boot up
If I connect the AC power to the system it will show full power (fan works - hard drive light is on and giving sound for reading the HDD attached to it)
The problem is it doesn’t complete the process of booting as the fan keeps running, but the light for hard drive is always on (which should turn off in 10 sec before boot) black screen, battery won’t charge.
So its getting power for motherboard but no process is going on (example if I connect a USB drive it shows connection light but won’t read the data)
Any advice will be appreciated and thanks in advance .
