1- it shows that the " base system device " is missing... i have no idea what does that mean !!
2- the "Fn" is not working properly, I can't change the brightness of the screen or the volume or another important functionlaities like the page up & down keys !!
3- I can't scroll on the mouse touching pad
4- I can't use the buttons which are at the front edge of the laptop to control multimedia stuff and to eject the CD-ROM !!!
