Well the first part has been done. Managed to find cheapest supplier of SODIMM memory that is compatible so instead of 2 Gb, it now has 2 banks of 4 Gb SODIMM (8 Gb) - interestingly, when I first installed the RAM it picked up nothing - Removed both modules and inserted just one - picked up instantly - swapped to see that the other was not faulty - picked up instantly - finally put both back in and all good! CMOS battery defunct - got one off e-bay, also installed. Just ordered a 1 TB Crucial 2.5 inch SSD to replace the 160 Gb HDD. Still waiting for that - ordered from Crucial UK - in stock - invoice from Ireland! Part being shipped from the Czech republic - went in transit to Pullheim in Germany, and currently stuck in the Hague in the Netherlands! Giving me time to look at SSD formatting options and whilst looking, stumbled on this great video on YouTube on Data Recovery lies for SSD!
Also fstrim or TRIM in general does not prolong the life of an SSD, it just improves read/write speeds so I shall be disabling TRIM period!
