There seems to be a nifty way to power off the Series 9 laptop (pinhole + paperclip) when the laptop goes into panic mode and using the on-off switch for 4s+ no longer works. There does not seem to be an equivalent pinhole on the NP-N150 (JP0PUK) netbook.
Any idea what to do apart from letting it run out of battery? (This is after a kernel panic when trying to upgrade ubuntu).
