Review on 8GB (2X4GB) DDR2 SODIMM RAM for Dell Latitude E6400 - PC2-6400 800MHz Memory Upgrade by Logan Goozmer

Works great, went to the internet to find out how, don't forget to hold the power button for a full 5 seconds after turning off the power, battery and cable to fully use all the remaining charge to discharge battery. System so as not to damage sensitive circuitry, and be careful by pressing the two on each memory module, the metal latches on each side, and then pulling out the old memory to install the new memory at the same angles, flat on the bottom and angled at the top, and if you haven't bent anything it works like a charm. Then when you just put the battery back in, just put it back in the terminals, lock it, slide the back, install the screw, without much pressure, it unplugs, plugs in and powers on. Now it works great, faster. Many Thanks.
