In 2012 I was given a 2009 Toshiba laptop by a friend who bought a newer laptop. My laptop is a Toshiba Satellite L455-S5975 with an Intel Celeron 900 processor with 2GB DDR2 RAM, 250GB HDD, 32-bit. It's been great, and I've been pleasantly surprised that it has lasted so long. But this year it has been slowing down. The signs of dying out are noticeable, and it's not the battery, as I have put in a new one (we non-techies can do this ourselves) and had it checked. So I decided to get a new processor. The processor is no longer being made, and none exist anywhere that I know of, so I can't buy a new one. Thus, 2 questions: (1) Is there a current processor that can be installed as a successful substitute? (2) Someone told me it would speed up if I added some memory, but the part he found on Amazon does not say it works with my laptop. Will it? The description on Amazon says "Kingston Technology 2GB DDR2 800MHZ SODIMM Memory for select Toshiba Laptops (KTT800D2/2G)". I would appreciate your input so I know whether to buy it and pay to have it installed.
