Normally I would not bother, but this time I don't really believe in concidence.
Yesterday morning, I have connected by ssh to my Raspberry Pi B model (the first B model - Raspberry Pi 1 Model B - 512MB) and run one after another (on Raspbian):
sudo apt-get update
sudo apt-get upgrade
That was the first time I have used rpi-update and after it has downloaded about 48 MB file, it run through the upgrade and ask me to restart my raspberry. I have triggered the reboot (I think incorrectly cause couple of minutes earlier I was rebooting couple of Windows systems) by command sudo shutdown -r now.
Raspberry has not boot up after this. Once I have arrived home, I have connected HDMI cable and found that Raspberry is not sending any video (check input on tv). Rebooted Raspberry, happy that it has started, connected by ssh and found that was disconnected after couple of minutes. Wasn't able to connect again (connection refused) so rebooted it again. Again, connected by ssh - found that it kicked me off after couple of minutes once Windows was trying to attach a mapped drive shared from Raspberry Pi. Once I have disconnected and connected my Rasperry Pi again, I found that no lights are on.
Today - I have realised that USB plug has went down. It was quite expensive USB Plug from "kit:" which never caused me an issues for over a year?(5V / 1A, drives connected by a seperate powered USB hubs with no back power going to raspberry Pi).
My question here - was it a total coincidence that I have lost a power plug after rpi-update or is there anything that I don't know about this process? I have already ordered another USB plug 5V this time with 2A, but I was just wondering if this was just a coincidence?
