it's a bad idea to open a thread for multiple problems as it makes solving them more difficult.  I will comment on the green line here.  You need to open another thread for the keyboard issue.

This is almost certainly an indication of failing video hardware -- either the screen or the video chip or both.

You need to connect an external monitor to the laptop.

If the visual artifacts also appear on the monitor, then it is a failing video chip and since those are soldered to the motherboard, they are not replaceable.

If the vistual artifacts do NOT appear on the monitor, then it is a failing laptop screen. While those can be replaced, the cost varies enormously by individual PC model.

For this information, you would need to contact an HP Repair or Service Center.
