This combination seemed too much for the vintage netbook. It started scanning for required updates and the battery started to gently dischage as it powered the machine. The Gorse Fox kept an eye on the battery and after about 15 minutes it was down to 95% - excellent.
Then the machine died with an audible click.
The Gorse Fox plugged it in and rebooted. Everything snapped back into life - except the batter which is now sitting there with a red cross through it. Dead. The Gorse Fox remembers how difficult it was to get a replacement last time, and fears that this signals the end of this device as a mobile computer. It may still have a use, but will have to relly on a power cable.
