I have reported at various times on the HP Tablet I bought a few years ago and how it was a disaster: five burned out motherboards in a year as well as three or four Bluetooth units having gone kaput ... they replaced it and I am still using that replacement.
The replacement HP is not that good in that I never feel confident enough to use the tablet features that I bought it for. Moreover, the fan whines and whines almost the whole time the computer is switched on. Well, that was until today.
This morning there was yet another power cut here: annoying and frustrating at the same time. Then I noticed after a while that as the HP was running on battery, I couldn't hear the fan whining and whirring away. Zounds! I have been party to all sorts of discussions with all sorts of people all over the web on how to stop the fan making such a racket. I don't think anyone has suggested unplugging the power cord to stop the whining before.
Once the power came back, I recharged the battery and then when the fan started whining again, I pulled out the power cord and, proof of concept, the fan stopped whining.
The thing now is to find out what it is about the power connection that makes the fan a bit shirty!
