    The fan is controlled by the BIOS, and I am pretty sure that there is no option to adjust it there. If the fan is no longer running, was it the exact same type of fan or was it an after market upgraded fan that might require more power? Does it run at all when you have the charging adapter plugged in or not at all, by chance?

    Hi it's was the fan below, it runs but does not increase speed when the laptop heats up. I restored laptop and updated all inc bios just to be sure, but no effect.

    daniele2015,

     

    Unfortunately there is no way to increase the fan speed in the BIOS, but the fan not speeding up or slowing down is another issue. I am uncertain if it is because it is not the exact same fan that shipped on the unit and has different power requirements.
