Hello all, my Acer aspire e5-551 with la-b222p motherboard and amd A10 processor has been gradually taking longer and longer for the screen to turn on, to the point where it either has to be switched on and off 10 times, or left on for 30 mins before the screen turns on. In addition to this, the laptop suddenly turns off after about 3 hours use. I put the latter down to it getting hot / thermal cut out as the base is hot when this happens.

I have cleaned out the fan, however it still gets warm. There was a period where there was no thermal paste on the IC which I think has caused this, it has now been replaced but the problems remain. Have I burned out the IC ? Do I need to replace the motherboard? Any advice would be really helpful ( I run by business from this) !

Thanks

Connor
