a) Yes... no sound from speakers... I'm pretty amazed about this O_o.
b) Yeah... I have tried to use the 1400 x 1050 resolution with no luck. I am bound to use a lower resolution. I looked carefully and observed that the so called 1400 x 1050 resolution in the initial setup was exactly the same as the XGA. I also checked what was bought and yeah... it's supposed to give a XGA resolution
c) I connected a USB Mouse and it is detected during the bootup . I configure it but can't use it.
