G555 Windows OS and CPU upgrade

Two part question...


G555 setup as originally purchased. Win7, 32-bit, AMD Athlon M320 duo-core CPU.  In Windows control panel when I look at specifications it tells me that the CPU will run 64-bit OS. If I install Win7 64-bit will I need to change any pin settings on the motherboard, or upgrade BIOS? 


As well,  I've read where the motherboard will handle CPU upgrades. I'm considering going to an AMD Turion II Duo M540. So, same questions as above... board setttings need changing, BIOS upgrade?

Hi there, Hokie-


Thank you for writing in to the Lenovo Forum - happy to have you here today.


Please click here for better understanding. However, no pin settings to be changed on upgrading to win 7 64bit.


Update us how it goes.

Re: G555 Windows OS and CPU upgrade

Thank you.


Can you tell me about the BIOS? (Insyde H20)


When I review the Lenovo drivers and software page, I thought I read where it indicated a BIOS upgrade for 64-bit. Do I need to install that driver first before upgrading to Win7 64-bit, or is that BIOS update pertaining to something else?  I'm always cautious about flashing the system BIOS. 


Also, if I do need to flash the BIOS, I set a password on it when I originally purchased the laptop 7 years ago and can't recall the password. Will it flash OK being password protected, or if not, is there a way to clear the BIOS password? Alternately, I as well have the HDD password protected but I can unlock the HDD. I could have sworn that I set both the BIOS and HDD passwords the same, but obviously not or at some point the BIOS password was changed, but again I can't recall and therfore I can't enter into the BIOS settings. I'd like to be able and clear/reset the BIOS password if at all possible. 


Thanks again for your help.
