wierd sound from my laptop

i get wierd sound when i unplug my laptop from power
the sound is like tq the sound keeps coming randomly about 15 sec.
the sound keep coming even mute the speakers it started to happen after i formatted my laptop.
any help would be appreciated.
sry for my bad english.

 

What does it sound like when you hear the sound? Can you describe it?

 

yeah its like (tok) and it happens randomly.
and i THINK that the sound came from the monitor

 

Could be the famous marble dropping sound from the hdd.

it sounds like a loud "tick" and it is a common sound from hard disk drives. No need to worry about it.

I had a high pitched noise like a constant squeal "EeeEEEeEEEE" coming from my laptop's screen inverter board. Apart from the screen inverter I doubt anything in the screen is capable of making a noise.

 

Which model do you have? And notice when it makes that sound, does your quicktouch mute button go out? If that's the case, let me know, cause I had the same problem right after I reformatted my hdd, and the only way i could fix it is to reinstall the IDT driver.

 

The speakers make a popping noise when power saving is incorrectly managed. The IDT audio driver should stop that from happening once installed. However there can still be issues with the power saving tech therefore I disable both power saving and external amp shutdown in the IDT control panel.

 

That is so weird... what laptop do you have?

 

i have dv2690ee

guys i have something else
after formating
when i installed the quick touch buttons driver
it didnt work properly eg: the mute button doesnt change to red when i touch it
and i dont THINK that the driver was installed properly either .
if it maybe from the quick touch buttons can u tell me where i can download another driver for quick lunch buttons.
and how reinstall the IDT if it necessary
and what is IDT O_*

 

IDT is the sound driver. To stop speaker popping noise go into the IDT control panel, click preferences, general, and disable both power management and amp shutdown.

to install quicktouch software go to http://h10025.www1.hp.com/ewfrf/wc/...&lc=en&cc=us&dlc=en&lang=en&cc=us&submit=Go »
and install "HP QuickTouch Software"

 

i installed the driver but still the mute touch button dont turn red
and can u tell me where to find the IDT control panel

 

IDT control panel is in the lower right tray. Do you have any audio?

 

i dont have this i cosince the first day i bought my laptop
and can u tell me why is my mute button doesnt turn red when i touch it.

 

dv2690ee do not use IDT sound chip, its Conexant HD-Audio SmartAudio 221 Driver.

Install drivers from your support page here

It will fix the mute light problem, but I'm not sure about annoying sound problem.

 

heh, I dunno why I didn't see that his laptop wasn't using IDT after posting that same link.

 

it worked the light is turning red and the sound disappeard
