What solution are you talking about? I've read your post, but there's nothing mention as a solution. Please, provide more information about the steps you have performed regarding the troubleshooting of the problem with your laptop.
What do you mean by “doesn't turn on”? The lappy doesn't turn on at all or it's just the black display that you see and the HDD and/or the fan are spinning. Please, come back to the topic with more information.
I'm sorry that I didn't mention what I tried to do as a solution
So,I've tried these following step :1) Unplug the power cord --> Remove the battery --> Hold the power button for 60 seconds --> Connect the power supply then try to switch ON the laptop and later..
So the laptop doesn't turn on t all itjust shows the light when I press the power button. My laptop is an Dell inspiron 15 3000 .
Thanks in advance for your help
