I'm having a Dell laptop as well and i cant say anything good about the customer support, the only replies or support i got from them was :"Sorry we can't help you, but you can buy a new system at a very low price blabla...".
Anyway thats my experience with the support ( of course this is totally dependant on who is in charge of it in your own country but with me they dont give support at all unlike IBM dozn here. )
