May i know can i install an additional 2GB RAM myself?
Will it void the warranty?
Where to open the case to install the additional ram?

should i buy an add on 2gb ddr2 800 mhz or 667mhz for k40ab?
does it can run at 800mhz?

the maximum ram capacity for the laptop is how much?

but why my everest just now i open shows 800??

o...maybe i see wrong place...
but why the effective clock of my everest shows only 647, not 667?

Added on November 7, 2009, 8:10 ammay i knows why sometimes when i shutdown my computer,just a second before the computer completely close, it make some noice (e.g jiza jiza) like it is going to burn out...
but when i start it again no problem at all...
it is likely comeout from the built in speaker of the notebook...

so, is it the time right for me to update bios to eliminate the problem of k40ab like jiji sound when shut down and screen remains black when back from sleep mode?
does the bios 213 for k40ab still has problem?
do i need to reformat upon the bios is being reflash?

Audio_VIA_WIN7_32_WIN7_64_60017333
is this the sound driver u means?I could only found this sound driver in the asus website..

why sometimes my 40ab cant back from sleep?the screen remains dark...
quite disappointed...sometimes the lappy is also slow like the desktop i used b4 this lappy, it used intel celeron... so slow when multitasking more than 3 light&medium program...
