Laptop gives off a high pitched screech ONLY upon start ups
I've just bought a brand new laptop 3 weeks ago and just recently I've realize that every time i restart/ shutdown and turn on the computer there is a short high pitch screech. The screech occurs where the windows vistas processing bar is running back and fourth during startup. (Sorry i'm not very tech savy so i'm not sure what that page is called.) I am positive that the sound does not emit through the speakers, therefore i guess it could be the fan? Please help, thank you for your assistance!

In Windows 7 ,Try the Power Options in Control Panel. Set to High Performance, select Change Plan settings, set Sleep to never, select Advanced Power settings, scroll through the Advanced Power settings, set Sleep and Hibernate to Never and Power Buttons and Lid to Shut down. Always shut down and unplug the Laptop when not in use to prevent damage due to a power surge and a possible Fire hazard IF the battery malfunctions. Not to mention unnecessary wear on the components.
1. Feedback created by a dry join on a circuit board 2. Feedback from a cooling fan that has malfunctioned 3. Feedback from a microphone that has malfunctioned
I would try disabling or fiddling with the settings on the microphone first, if that's the problem, I recommend you disable it and if you use a microphone regularly, the external alternative is quite a cheap way of replacing it, if its a cooling fan, and you have the knowledge to disassemble the laptop, try disconnecting it for a short time, if the feedback stops when you disconnect the fan, you need only replace the fan, if these two methods don't solve the problem, I would recommend you have a professional look at it for you, dry joins are quite hard to find and require special equipment to fix, and if that's not the issue, the professional should be able to find the problem anyway.
In the situation like this were you have just bought the laptop a week ago i suggest that you take the problem to your buyer. If the laptop is Brand New then it definity shouldn't have this problem but if it is used then you might need to ask your buyer for any problems that the owner before you had.
This is going to be a problem either with the sound card malfunctioning after the machine warms up, or feed back from the speakers due to a wiring issue. Either way, this is a hardware problem, and you shouldn't have this or any problem with the machine, especially with it only being 10 days old. Take it back for an exchange. Demand an exchange and don't let them give you the run around. When you get the new machine, you will see that you shouldn't have any problems with it for years to come. Also, don't let this bother you about Dell machines, they're one of the best machines on the market. Just like everything else, there are a few lemons.
