Hey guys,

I have mountain lion installed on my msi laptop. All is working fine, except two things.

1. When i unplug the charger, all functionality freezes and I get a message that I will need to shut off the computer holding the power button and I cannot do anything until u turn off the computer and restart it again. I guess this is something related to dsdt, but not sure.

2. The laptop doesn't go to the sleep mode by clicking the power button as I have set it up. If I put it on sleep manually through the control panel, It never wakes up until I turn off the computer completely.

Could you please help or advise what to do ?
