How to remove the back of a laptop?

i have a dell latitude D360. My speakers on my computer give a crackling sound when played and a friend of mine reckons it mite be a lose connection (i have tried all the software ways of trying to sort it).

How do i get the back of my laptop, i have undone all the screws but cant get the back off and i dont want to force it, im trying to get to the sound card so i can check the connections?

Thanks

 

sorry i meant d630

 

ok so now ive got the back off and had a look around. Im trying to find the sound card, i think i have a lose connection because the sound is crackling. where would i locate this?

 

Hi Deviant,
I've pulled a couple of Laptops apart and would recommend that you Download the Workshop Manual and thoroughly make yourself conversant with the operation and have containers available to put the respective screws/bolts/nuts in and label carefully as quite often they are dedicated lengths/sizes and you can cause severe damage if you fit the wrong screws in the wrong place when reassembling. Most laptop Motherboards have the components inboard and sound systems usually are. I would suggest you look at the wires near your speakers as the wires can get damaged if they are not installed in the correct place. If you need to solder the wires in place make sure you have a low voltage soldering iron and suitable heatsinks to prevent heat transfer which will damage the internals very easily. Voltage spikes can destroy electronic components in nano seconds - so be careful. Naturally ESC's will also damage components. Use a suitable earth wriststrap. Best of luck. Neil.
