I have bought a DVD reser writer to replace my CDRW DVD Rom Combo. I was told it is a simple in and out op but wonder what prexautions I should take aprt from disconnecting the computer from the mains supply. Advice appreciated.
I have in my mind that there can be residual or static electricity in the computer box that can give a nasty jolt or do other damage. Is that so and how can I avoid? Would powering off for a considerable time bfore opening up be ggod but how long?
