I upgraded the RAM in my laptop and now when I attempt to power on, it won't boot. The power led comes on and the optical drive led comes on but not the HD led. It will spin a CD but won't boot from it. I put the old RAM back in and it does the same thing.
Also, I changed the little round internal battery as the clock had been resetting every time it was turned off. Maybe I messed up the bios when I took the battery out?
It was working fine before I messed with it. It's about six years old with an Intel Centrino cpu and running XP. Any thoughts?
