Upon pressing the start button, a sound similar to a short, deep note on a piano is made inside computer and it will not open up.
I must shut down and attempt again a minimum of 3 to 4 times before computer allows self to open.
Ideas??
Thank you

From your description it sounds like something interfering with the fan, like a matted lump of dust and fluff rubbing on the fan vanes. If the fan is actually prevented from spinning at a reasonable speed the firmware will probably detect this and could well decline to start the computer for fear of the processor overheating.
First of all, try poking a pin through the air vents to see if you can dislodge any matted dust then try and suck it out with a vacuum cleaner. However, you will probably need to disassemble the laptop (not that hard) in order to gain full access to the fan.

Hi,
How far does it get into the start sequence,
Lights on, fan running, maker's logo, error messages etc.
Does it do this when connected to the charger?
