Question about Dell Inspiron 1521 Laptop
I have a 1 1/2 year old Dell Inspiron 1521, which whistles when the battery is unplugged and I turn the screen brightness up. And when the battery is plugged in the right half of the screen is much darker than the left. As I work on the computer longer the screen gets darker.
You could have a defective screen, either a faulty inverteror a CCFL lamp - follow this to determine the fault.
Defective CCFL backlight, it may have the following symptom:
Connect an external monitor to your laptop and power it up, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight.
Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

There is high possibility that your adapter is stuffed. Dell have built in a recognition circuitry
into the 65w adapters and when that goes, the system will no longer recognize
it as a 65w adapter even though it is still putting out 65w. The system then
shuts off the battery recharge circuit and to make matters worse it won't even
charge the battery when the computer is off. It also
speedsteps the processor down to half its speed so everything runs slower. Only
option is to stick with a slow computer that can't be used on batteries or buy
another ac adapter.
you do not want to pay $80 for a original adapter directly from dell,
there is an alternative choice to get an 3rd party charger, check this
