I bought a 256gb Samsung 240 on Black Friday to replace the Momentus XT I had been running for 2 years. I noticed, however, that the battery life with my SSD is pretty abysmal. I'm getting 2-3 hours MAX, even when the computer is sitting idle. With the Seagate drive, I could at least get ~5hrs or so. Am I missing some fundamental setup step, or doing something wrong? Or am I just expecting too much?
