Hello everyone! Today is my first day in forum! I have a problem with my laptop Acer 5741z. Working normally, but the time came for the prevention of cooling. I do this many times, not only on this laptop. Disassembled the computer, cleaned it, but once you put together does not start. I guess I made a short circuit on the motherboard. What I did so far is as follows. I tested the charger jack. Operate normally. I tested power button board and work fine.
Please direct me to where I can look for problems. I noticed that when i put the power in motherboard chipset starts to heat. And this happens without I start the computer, only put the charger. Motherboard model is la-5892p. Sorry for bad english!
Thanks to all!
Regards
