its usually F2 or Delete button to access the bios, have try that

- Did you tried Control + F2 and Ctrl+F3?

Hook a external keyboard to make sure it is working, if yes! the laptop keyboard will need to be replaced.

I suggest you start diagnosing by using an external monitor, if available.
A VGA monitor.

(It can be a VGA monitor that looks like a small TV, {CRT}, or an LCD flat screen that has a VGA cable attached.
More information on VGA connectors,

http://en.wikipedia.org/wiki/VGA_connector

Laptop off, and VGA monitor off, connect the VGA cable of the monitor to the Left side of the laptop.
(Rear top port)

Turn the monitor on, and then the laptop.
Do you see a display on the external monitor? (VGA monitor)

No?
Press, and hold down on the Fn key (Function Key), and tap once on the F4 key.

A) If BOTH the external monitor screen, and the laptop screen have the same pinkish display, the problem is the graphics chip. (More on graphics chip in a moment)

B) If just the laptop screen is pinkish, and the external monitor graphics are okay, the problem is inside the laptop display.

1) Could be a loose connection of the Display Panel Cable.
{The Display Panel Cable attaches to the motherboard, and the LCD screen in the laptop display}

2) Could be a bad Display Panel Cable.
Possible damage to the Display Panel Cable is the the laptop display was open.

Look for signs of damage to the sheath of the Display Panel cable.
However the damage may not be apparent. The Display Panel Cable could have been stretched.
(Laptop display open when dropped)
The tiny wires inside the Display Panel Cable could have become damaged.

Testing requires that the Display Panel Cable be removed.
A multimeter is used to check continuity of each wire.

{Multimeter function knob is set to Ohms. 1K or 10K if these settings are available.
The Positive probe lead (Red) is touched to a wire at one end of the Display Panel Cable.
The Negative probe lead (Black) is touched to the other end of the wire.

Analog multimeter needle swings up, you have continuity. Don't worry about the Ohm reading at this point. As long as the needle moves.

No movement? Have a helper gently move the Display Panel Cable around.
See if there is continuity shown, or is intermittently shown.
Indicates a break in the wire.
Solution is to replace the Display Panel Cable.

Same with a digital multimeter. No reading, or intermittent reading indicates a broken wire.

Display Cable Kit - HP Part Number 595196-001
I have seen several listings on the internet.

3) Could be a bad LCD screen.

Check the connections.
Check the display panel cable
If this checks out okay suspect the LCD screen.

It doesn't look like you can replace a single key on the keyboard. You would need to replace the keyboard.

This link is for the service manual which explains how to remove the keyboard.
