How to enter the bios to change boot sequence on a lenovo 3000 n500 laptop

it's is locked because it is password protected. if it's not for you, ask the owner for the password.

Even if you enter the BIOS and attempts to remove the HDD password, You will still need to produce the password before you can disable it.

Do any lights come on when you press the power button? If not, did you get all the cables reconnected properly? If lights come on or fans come on when you press the power button, then it sounds like the screen has gone bad. That is the symptoms you are describing.

Clearly it's a hardware issue if your laptop is still in warranty call lenovo thinkline @ 18004267378 because it might be a possible DC-IN port or motherboard problem..Request for service repair.

I do. Open the Lenovo 3000 N500 Notebook PC, and un-stick it.

You need the Service Manual.
Lenovo calls it an HMM.
Hardware Maintenance Manual

Below is the Lenovo Support link for the download page, for the Lenovo 3000 N500's Hardware Maintenance Manual. The Top file listed is the one you want.

Either the site is updating right now, or Lenovo no longer offers this manual. Clicking on the file does no good.

No big deal.

Copy this link, paste it into your address bar, and press the Enter key.
It's a direct link to the HMM file.
