Lately my HP 17" laptop model #1008ca after waking up or sitting for a awhile the hard-drive or maybe the fan is running..
its a humming sound that usually occurs when the windows 10 is doing backups or programs running .. but nothing is on.. just my wireless and virus checker from windows 10 security .

HP support was useless wanted me to 'up my warranty' and then send it for repairs .. its only 8 weeks old .. this model is the $800 model not the $249 or 499 model ..

any ideas for troubleshooting ?
