Try to power on the laptop without using the power cord, if the laptop doesn’t on, then the battery is dead and you have to power it using the power cord. After powering on the laptop with the help of the power cable, if the laptop doesn’t show any signal, then there might me problem with the power cord, otherwise the power LED will on and the desktop will appear on the screen.
If there is power and still the desktop doesn’t appear on the screen then it may be due to faulty display, hard drive or OS.
Now boot the laptop with a bootable recovery disk using the disk drive, if the display appears in the screen then the problems lies with your hard disk or your OS is corrupted. Try to reinstall the OS, if not possible replace the hard drive from the laptop.
