I have a notebook that went virtually dead after a memory upgrade:
The Toshiba Satellite M45 notebook came with 512MB RAM in one slot and a second empty slot. I attempted to remove the existing 512 and replace it with a 1GB stick and add a matching additional 1GB stick in the second memory slot.
Upon reboot, this resulted in the computer essentially freezing up, emitting a strange sound and displaying a flashing keyboard lighting sequence where the CAPSLOCK key lights up in green, and at the same time, green lights below the F10 and F11 keys turn on and then off. I have a video of the laptop posted on line that shows this phenomenon.
Currently, the computer won’t boot from the Windows XP disk and won’t boot to the bios. I attempted to put the computer back to its original state by uninstalling the new memory and reinstalling the original memory, but the computer started up with the same problems.
The original manufacturers spec sheet and a Belarc system scan done two months ago are attached as pdf files. The exact memory and computer specifications are as follows:
Memory: Initially configured with 512MB DDR SDRAM in one slot with second slot empty.
Attempted to remove existing RAM and add two sticks of 1GB Corsair Value Select RAM DDR-333 (PC-2700) SODIMM Latency 2.5-3-3-7-2T (VS1GSDS333) per the recommendation of the Corsair memory configurator. [http://www.corsair.com/configurator/system_results.aspx?id=55088]
