Upgraded my i3 330m to i5 560m and there is no display but hard drive and fans works and caps lock blinks…… But again had to switch to i3 and it works fine….. I hv not tried to remove CMOS battery during upgrade to reset the bios, can this step solve the issue
md. shadaab sheikh since it works when your go back to using your i3 330 m and does not work with your i5, your motherboard is having an issue recognizing your processor. Most likely that it is a compatibility issue with your motherboard.
