1 Answer

The laptop doesnt start up. cooling fan is brocken. thermal oil is old and almost dry and little

my toshiba sat a 45 fan did not work so I shut down the laptop after 3 min then I opeend the machine I saw that the cooling fan for the heatsink is brocken beause there was a short in the wire (yellow wire) then I tried to on it without fan it did not start I offed it after 30 seconds then put the brocken fan I mean bluged it also did not work. my thermal grease is very little almost dry the heatsink gets very hot when I oned pc for tese 10 seconds. just I see green light or some times the orange light of power blinks.

there is no toshiba service in my city and all others said mother bord might got brocken but they guessed they havent opened it and checked even. laptop doesnt smell bad even this cpu small chip doesnt smell I offed it fast though, so what should I do? if there is brocken fan it wont start? I mean the pc. if there is less oil it would burn the chip in 30 seconds of starting ? but why so if the fan even some times stops working for long time in usual working please tell me if there is something I can do to fix it

Sometimes depending on the version of BIOS there is a thermal shut down feature,If the CPU gets to hot it will shut the entire system down.What you can do is replace the CPU fan and apply more grease in between the heat sink and the CPU chip.If this does not solve your problem then you may have damaged the CPU.the best way to fix this is to replace the motherboard and CPU.Try replacing the fan first because if your computer has the thermal shut down feature then chances are that it protected the motherboard and CPU from any damage.Try the simple things first! GOOD LUCK.
