Have the same problem, as described here http://en.community.dell.com/support-forums/laptop/f/3518/t/19601642?db=5 .
(Whenever it gets switched on, it makes a weird crackling noise. The noise seems to be an issue, because it only happens when the laptop is plugged in AC without battery, or plugged in AC with battery fully charged. As soon as i pull the plug, the noise stops. Or when i close the program that uses the HD radeon graphics.
Description and source of noise : It sounds like a noise that caused by electricity. The closer sound that i found to describe it, is from bicycling when stop doing pedals. (youtube.com/watch?v=ajFdrfOc5As&t=0m3s) The noise probably caused by the GPU Radeon HD 8850m. It comes from somewhere in the middle of laptop when it is plugged in AC and the battery is fully charged. The noise stops when battery is still charging or when its disconnected from power. (Probably because the laptop uses DC then)
Also, the noise starts as soon as i open a program that is set to use the HD radeon card. For example during a game, the sound is continuous and it pauses a bit during loading screens. On Photoshop, it only appears when i draw a line, or paint something and then pauses. So basically, the GPU emits that noise whenever it gets used and is under AC power.
Is there any fix for this issue? Or most importantly, is this going to cause any harm to the GPU or laptop in general?)
Please, please, please help me.
