this laptop is just too much.... first i had a problem with the BIOS and I still have it and now the weirdest thing happens. After i start-up the comp. it loads the windows and after 1 min the screen dims. At first i thought the screen just went off, but i looked closely and you can barely see the desktop. the period afrter i turn the laptop and the screen dims is between 30 sec to 3 min, it;s not always the same period of time. it's not from the battery beacuse i took it out and has only the AC cord in it. This happened after i took it appart and i assembled back. i double checked the connections but nothing...
