Hello,

 

As the title says my Lenovo z565 Windows 7 laptop seems to power on (lights work) but the screen stays black. I do not get a windows logo or any cursor. I also notice when I plug in or unplug the power cord the computer beeps which it did not do before. I also tried hooking the laptop into another output device I know works but I still get nothing on the screen.  Any help on this topic would be great! Thanks!

Do you get the Lenovo logo when booting? If not then pull the power and main battery. Hold the power button down for 30 seconds. Replace the power adapter but not the battery and see if you can boot.

 

If nothing pull the hard drive and it may through an error where you can access the BIOS. If that happens it's probably a hard drive failure. If still nothing it may be the power adapter or charging circuit, or some other hardware issue. You can test your power brick with a multimeter if you have one.

 

This person had a similar issue and it was the video processor. The video shows some nice troubleshooting tips.
