My laptop screen is black after i turn on the power button .
I strongly recommend you to disconnect the battery and the power cable and to hold the power button for 30 seconds. Reconnect the power cable and try again. If there is no change, try with another power cable. In general, there may be a power related issue or a motherboard problem. If the laptop is under warranty, contact the seller and ask for guidance. You may need to have the PC checked by a technician.
