I’ve previously mentioned briefly about the overheating of my lenovo laptop, and how it frequently just shuts down and will not allow a restart for an hour or so while it cools down. I’ve also mentioned that the last time it shut down, I have had NO video since. The machine sounds like it boots (or goes someway towards doing so), but no display. Nothing.
I’ve FINALLY found the time to book it in for repairs. While on the phone, the lovely gentleman on the other end of the line told me to remove the power cable and battery, then hold down the power button for 20 seconds. Apparently this resets some bits and pieces on the board. After which, upon plugging the power back in I was able to semi-reboot my machine (it froze at the ubuntu splash screen, but I’ll work on that another time).
It is still going in to see if they can stop it from overheating – probably just needs to be opened and vacuumed, but warranty stipulates I cannot do this myself.
So… I didn’t know about the 20 second deal. I thought maybe this could come in handy for someone else with a lenovo that won’t boot. I don’t know which models this works for.
