Problem Description:
Hello Dell, i've e-mailed yesterday about the problem wih the DELL studio XPS 1645 witch is very annoying. 6M1E6P561YS2FF1EL . I've already updated the bios to version A07 but throttling is still there. When i play games, the laptop uses most of the time 90 watt witch says 90 watt isn't enough to power this laptop. I hope the problem is already noticed with many laptop the same type as mine. I was asking for a 130 watt adapter please. About the issue:http://tiny.cc/ryWim
