Microsoft (again)!
Please stop trying to kill my lovely but aged Sony Vaio laptop!
I shut it down a week or so ago, and waited to be sure the little green light had gone off, so it really was off, but no, I fish it out this morning, because I want to connect my Aftershokz headphones to it, and its as flat as a flat thing that has been steamrollered to deth.
The reason becomes evident when I plug in the charger, it had evidently done a Windows update secretly, which meant it wasn't off at all, it was playing with itself. What benefits did I gain, from eventually getting it fired up with this wondrous new update? The bloody bluetooth was dead, that's what. That's a really useful update, killing the bluetooth, but not as bad as its previous habit of killing the wifi (on a laptop that annoyingly doesn't have an ethernet port, and relies totally on wifi). I eventually re-find device manager, which is harder since control panel was forcefully removed from my clutching fingers, and find it claims not to have bluetooth, and it has several "unknown device" entries. Finding the bluetooth drivers for an 8 yr old laptop is sketchy, but I find a hopeful looking one using the desktop, after having to download a utility that will actually tell me the model number of the laptop (I have nothing with its model number on it), and I try to email the driver to myself to pick up on the laptop. No dice, gmail refuses to send .exe files... rummage for USB stick, take it to laptop, and yes, it actually installs, and actually works! Can I have that hour of my life back please, Microsoft?
