Hello!Since this morning my laptop started acting weird.After about 10 minutes it shuts off.I never had any kind of problem with it until today.I thought it might be overheating but I let it idle and it does the same.I thought maybe I should clean the fan but it is not easly accesible and I m not really sure I have the confidence to remove the entire bottom.
I have an Acer Aspire 5742ZG.

It may be that, also it may be a failure in the mainboard.  If you're not confident, then take it to a technical service.

I actually took it off,cleaned the fan and I saw nothing wrong with the wires.Unfortunately I don t own a multimeter to test it but I m curious about something.If it s a problem with the motherboard,what are the possible problems it could have?The pins that connect to the fan or something else?

No. What comes to my mind is that it has a problem with energy. Maybe in the capacitors but I bet a problem where the voltages are below or above normal in an area of the mainboard and it overheats that sector and then shuts down.

 

Have you changed thermal paste? That's something you could try and see before expending money in technical service.

Thank you very much for your response,I think I get the general idea of the problem.As for the termal paste,it wasn t changed.I have this laptop since 2012 and I never opened it until yesterday.
