hie guys..does anyone know how i can make my laptop work again..

well i can't get it to start ..it keeps on blinking the power light so it wont even go to where it starts to boot..

it's a dell c345.

Most likely a hardware malfunction.
Try taking the battery out, then power on.
If that's not holding it from booting you'll need to troubleshoot the hardware starting from the power supply.
