My Fujitsu lifebook S series' fan stopped working. I left it running for a few hours and i did not switch on the charger. It switched off as it was running on the battery. I putted the setting to Shutdown at critical battery mode. I came back and when i switched on my laptop, There was this thing that told me "Fan Error" and i realised that the fan isn't working. Now i couldn't charge my laptop and i can't turn it on for long because it might overheat. I need serious help.
