PACKARD BELL EASYNOTE TN65 - Ho problemi con il raffreddamento del mio laptop.

Se non ci sono problemi che puoi riscontrare visivamente dubito sia un problema hardware. Comunque potresti aiutarci facendo queste cose:
1. Apri un terminale premendo CTRL + ALT + T
2. Inserisci ed esegui questi comandi:
uname -a
lsb_release -a
lshw
lspci

Poi copia tutto e incollalo qui.

Poi potresti installare un software per vedere le temperature, seguendo questo wiki:
http://wiki.ubuntu-it.org/AmministrazioneSistema/LmSensors

Il problema potrebbe essere anche di natura "fisica" nel senso che il portatile potrebbe essere sporco o cose di questo genere. Prova a tenerlo un po' sollevato dal piano di appoggio con dei piedini. L'età che ha potrebbe giocare un ruolo fondamentale in questa situazione, visto che non credo che tu lo abbia mai pulito e con gli anni tendono a riempirsi di schifezze varie.
