[linux-laptop] [newbie] power switch off problem on lap-top

[Jayant Ogale]

hi,
i have installed mandriva 2007 on my sony s4m lap-top.
the os is running smoothly but there seems to be many small problems.
1] even after enabling acpi, when the halt command is given or even with the
log off > switch off computer, log is received up-to system halted and then
nothing happens [i mean power is not switched off]. i have to do it
mannually each time. what is the solution?
2] attached printer and scanner gets detected properly but does not get
installed / configured.
3] modem [HDAUDIO soft V-92] does not get installed.
4] wireless card is detected but does not get installed.
somebody told me that if i installed the system from the freely downlodable
cds or the dvds which we get along with some magazines, many of the so
called commercial drivers are not provided with these cds. But if we
purchase box-pack from the company we get all these drivers with it.
is it true? if yes, what can we do about it?
thanks,
jayant
