Re: Problem with the screen of a Dell Inspiron 1521
In your caseHi
normally with vertical stripes it can happen due to
1.a bad LCD (small little chip inside LCD and can't manual repair)
2.a loose connection cable
so here what I do is first I try to tap at the back of the LCD and see that the problem goes away or not.If yes then a loose connection.
if no what I would do here ,coz I have a spare LCD I just exchange to test it...if the problem goes away then a BAD LCD.
Incase of verticle line due to bad LCD you can't repair it trust me.All the small IC chips are blended with board and can't really be repair.More quesiton feel free to post here.

It is a posible LCD problem, Might gone defective.
First trouble shooting is to turn off your laptop completele and the remove the battery and the charger and any accesories connected on yur lap top. Then press the power button for 1 minute. It will reset the settings of your laptop to default if you accidentally press the command for the hotkey to turn off the built in monitor and enabled the extended monitor.
If the issue persist it means it is an issue with the LCD and needs to be replaced.
check you drivers for you audio device might need to be uninstalled and reinstalled. to do this right click on my computer (xp) or computer (os higher thank xp) and go to properties click device manager find sound in the list double left click on it find you device right click uninstall, remove driver click on the icon in the top of the device manager that says scan for new hardware changes when you hover the mouse over it reboot and try.
I would always go with an extended warrenty dell pc's usually don't use the best hardware and tend to die in the 2-3 year range. The only reason I would say don't get it is if you are just going to go out and get a new if that one dies anyways.
1. sound driver
2. microphone settings in volume control applet
3. tap test (tap the area around the microphone and see if eg Sound Recorder picks it up)
4. external microphone
If you get to step 4 before you get anything then your problem is one of missing or damaged microphone.
