|To bring matters up to date.|
1. The Dell OptiPlex 755 Tower to replace the Dell OptiPlex 760 SFF which died has been giving the dreaded 0xc000000e Boot Error when my main USB external drive is attached for imaging the 755. Also, F2 and F12 weren't functioning but solved that by downgrading the BIOS from A22 to A19. Strangely, an older USB external drive works fine.
2. The Samsung Galaxy S mobile phone still gets the "Registration failed (13)" error at times, but usually when away from home. No coverage perhaps? Love the phone though, so will probably live with the slight inconvenience.
3. Finally took my wife's Dell Latitude D820 laptop apart today. Fitted the new CMOS battery I had bought and removed a layer of dust covering most of the length of the internal fins behind the fan. The fan itself was barely dusty. Only time will tell whether this will fix the laptop switching itself off, however, I also added a Desktop Gadget to indicate the core temperatures and also a program to change the fan speed [mainly for testing] and sound an alarm if the CPU gets too hot.
Now to continue with my cleanout of 30 odd years of computer collecting.
