Hello, I have the absolute same issue as Asadmujtaba. It is not a OS issue, because I have tested it with both Windows and Linux and the result is the same - when the charger is connected, the touchpad does not work properly if at all. When on battery, however, everything is fine. This happens...

Hi. I'm having a problem with my Dell Inspiron 1720. When it is plug in (with original adapter) touchpad mouse is constantly freezing, plug in mouse is not working, and i hear a buzz in my speakers. When it works on batery everything is ok. Is the problem adapter or something else?

I have been having problems with my XPS L502x I use to play Saint Rows the Third on my laptop it use to play perfectly but now after a year I restored my factory setting now when ever i install any of my old games they start off perfectly but during the game it hangs a lot kindly help me out.

OK,below is a conversation between dell customer service,a supervisor and I.This is pretty much self explanatory for the reason I refuse to buy anything from dell again!!!I suggest if you buy a dell don't expect to get anywhere with customer support or service for any issues that you may have!!!...

I've attached a picture of my $800 paper weight referenced in my post on 4/3/12. She's a beauty and really holds paper down. Doesn't do anything else though.
