I bought a Dell Inspiron 9400 in sept of last year. A few months ago I started having problems with it charging, with the usb ports working, the speakers stopped working, and the processor would only run at half speed most the time. I sent it in to dell and just got it back yesterday and it still has the same problems except the speaker works now. What happens is sometimes it just doesn't recognize the charger (which I don't understand because they had the computer and the charger, they should've known there was a problem and fixed it) and it'll start up running at only 1ghz instead of 2. Every once in a while it will go back up to 2 ghz but if that happens it sometimes stays but sometimes drops back down, and it always starts up running at 1ghz. Dell claims to have replaced the mobo and the processor, and they said they were going to check the charger (not sure if they actually did it). So, if I have a new mobo and new processor and still have these issues could something else be the problem? Or, does it just sound like dell is full of crap? Btw, I contacted Dell again and they just told me that I have to use if for a while and then get back to them. But, I don't see how using it is going to miraculously fix the issues.
