Yes. My original CPU (RM-74) died some days ago. I have problems finding the exact CPU but I found the RM-70 at a good price. I asked official service to sell me the RM-74 but they told me that they do not sell individual parts, this lap is no more under warranty and they charge me for servicing it. As I feel capable to do the replacement myself I'm started to look for a compatible CPU and the RM-70 was the one I found. I work with this lap and need it now, I can take my time to find a better CPU latter.
