My HP Pavilion Entertainment PC; SN:CNF730104M with Window Vista Home Premium will not come on. It was left being unused for a couple of months being plugged into the electrical outlet. Now when I turned it on the lights flick on for two seconds and go off. I have tried leaving all cords unplugged for a day and restarting but no sucsess. Can you advise Please. Thanks Robert Bisko

The problem may be because of the graphic driver of your laptop. Do you upgrade your graphic driver?

I believe it can be resolved without purchasing a new laptop.

Windows is a 'funny animal'. Sometimes Windows just looses it. You need to reinstall your audio device Drivers again.

It's Integrated Audio used on the HP Pavilion DV6700T laptop. An audio chip soldered to the motherboard.
Another term used for Integrated Audio is OnBoard Audio.
On the motherBoard.

Chip and Chipset are slang terms for I.C.
Integrated Circuit,

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

(If it wasn't Integrated Audio, it would be a separate audio adapter card. {Sound Card} The audio chip is soldered to an adapter card. The adapter card is removable. This would allow replacing the audio adapter card. Not happening for an HP Pavilion dv6700t laptop)

Drivers are small software programs that allow the Operating System to communicate with the device.
(Windows XP and Windows Vista are two examples of an Operating System. O/S)

There is an HP Pavilion DV6700T Entertainment Notebook PC series, and an HP Pavilion DV6700T SPECIAL EDITION Entertainment Notebook PC series of laptops.

I need to know what Operating System you are using. Do I assume Windows Vista? (Windows Vista Home Premium 32-bit)

Going with Windows Vista, here is the Audio Driver download page for the Pavilion DV6700T notebook, (Laptop),

Doesn't matter what version of Vista it is, this audio file is for all versions of Vista.

On the above page left-click on the + sign to the left of -
Driver- Audio (1)

Now go to the right, and left-click on Download, in the rectangular box.

A small box will come up, Opening sp38899.exe
The name of this file is sp38899.exe

Left-click on Save File.

The file will be saved to, where ever your downloads are set to save to. The file needs to be found, then opened in order to work.

When you see the audio file (sp38899.exe) Double-click on it.
The Windows Installation wizard will lead you through installing.

If you are asked to restart your computer, do so.
If not, restart your computer.

You need to go to your laptop manufacturer's website and download the proper Windows 7 driver for the video card.

Contact HP fast..
The computer is under warranty.
They will fix the issue in free..
But the problem is to fix the issue they would pick up the complete notebook for mail in service..

I'm assuming your running vista Premium - go to control panel - audio - selected properties - recording - mute it to 50% when in operation then apply close and reboot. this should restrict the sensitivity of the inbuilt microphone - if you have upgraded to W7 you will need to upgraded the audio driver package using the vista audio drivers unless there is one on the HP website.

I have the same machine. They no longer give manuals out. You have the HP help center installed in vista home premium if it's the same as mine. You have to go to the website in the hp help aplet, in order to find specific answers. Don't feel bad, my 2 Samsung LCD tv flat panels are the same. No books anymore, it saves them money

I had the same problem called linksys on the phone they walked me through the whole prossess over the phone.

frist you will have to uninstall the windows vista competely .
(the simplest way is to format the drive in which  you have vista installed)
but even after that you might have the vista boot screen left  to remove it download a software 
"vistaboopro"
after instalation
try this site  this one really helped me out  and will ceratinly help u too
