Vaio overheating to the point of melting

[Sass1278]

Hi,
I have a 4 year old Sony Vaio AW series laptop (M/H31) and lately it has been overheating to the point that HWMonitor shows that cores and GPU is constantly running at 80 or so degrees, and only Chrome and Skype running. When Chrome is off it cools a bit down to 70. There are almost no background ops running as I have disabled everything that could be disabled.

I took the laptop apart to clean it from dust and replace the thermalpaste and found that the plug which connects the wire coming from the DC port has partially melted and is charred. Does anyone have any ideas what might have caused this?

Also as I opened it up and ran benchmarks in order to stress the system to find sources of heat, the GPU stayed below 50 throughout the test. Motherboard chip went high in temperature(ca. 60-70), but not sure how much as no readout on this one. The CPU reached 90 degrees simply by opening the program and stayed there as long as PC Benchmark was open. This was with backplate off, so cooling was superb for the the insides.

Any ideas are welcome as otherwise the laptop is a write off and I don´t have money for new one

Make sure you pull the fan out and actually clean the entry to the heatsinks - the laptops I've pulled open usually have a mat of dust there.

Hey, cheers for the input, I have made sure the dust is gone everywhere

The CPU still goes haywire, I´m currently trying for last hope, format the HDD in hope it´s Windows that goes nuts for some reason.

The melting point is by the plug where DC wire connects to the motherboard. It has 4 prongs, 2 for black wire and 2 for red. The 2 which are for black wire are charred and the plastic plug has melted around it and is overheating contantly. The ones for red wires are perfectly fine, no sign of trouble there. I can ofcourse order new wire, but I doubt that will fix the issue.

Help?

Replace the fans and see if it overheats.

This is very common and most people simply don't care till it is fairly broken so I end up buying them as scrap for as little as $10 a pop. You have to scrub the cooler with a tooth brush and use a bristle brush for scrubbing the fan. Use only the best compound on the market and you won't have thermal issues. As for the DC jack this is also common that people don't push the jack in all the way so the current has to flow through a lot let metal to it gets rather hot. You can replace the jack at a minimal expense.

The DC Jack might of not been grounded well it connects to a metal piece on the laptop(not apart of the motherboard i think) is probably causing the connection to overheat and make everything else all wonky . The DC jack needs to be grounded properly. You need to solder a new DC jack onto the motherboard... you can look it up online by laptop model...Also I know in the past there have been Sony laptop recalls for laptops overheating.

Hey,
thanks for the answers. I already sold the laptop as "spares or repairs" as the amount of faults was going over the top already. Cheers
