    Re: Laptop shuts off by itself, overheating?

    Off subject, but I did figure out while hooked up through hdmi on my big screen, that I can watch movies normally without lag just by lowering screen resolution. Bad part is that the hdmi sound doesnt play and I have to use line in for sound...Good luck on your laptop, and I looked at your blog..nice!

    superbatlife - I have found that changing the audio output option switches my HDMI sound on. It switches off the laptop sound but, hey sound through the HDMI is better than not.

    Hello Danny - been having a look at our small Acer laptop using acpi & sensors - the Celeron 540 cruises along happily for hours at the temperatures you are seeing. Not entirely certain that it is a temperature problem, although it does look that way.

    Anyone else have a view on the temperatures seen?

    i was going to run a memtest on the RAM, but when I tried the laptop had already been on for a while so in the middle of the memtest, it shut off. I just attributed it to overheating again BUT i wonder if it's a bad ram issue if you're saying that the temps i posted aren't that high. Though i don't think i had facebook pioneer trail open when did that test with lmsensors.

    Re: Laptop shuts off by itself, overheating?

    Its seems as though re-doing the thermal paste between the heat sink and the cpu has made a huge impact. I followed this guide for disassembly http://www.youtube.com/watch?v=VGzqoVH8b7g

    The vent for the fan to blow hot air out was completely caked with dust and dirt (on the inside) as well just as they showed in the youtube video. The fan hardly even spins up now, whereas before it would spin really loud probably to make up for the fact that it wasn't venting out the heat from the heat sink. I used Arctic Silver thermal paste.

    I ran sensors again and it showed temps around the same as last time 58 to 62 degrees celsius BUT that was after playing Pioneer Trail for 1 hour and having other videos playing in Youtube. I am guessing that it's fixed now. Whereas when I ran it and posted my results before, that was immediately after turning it on without doing anything else. LOL

    Hope others can get some help out of this thread. Thank to everyone for their help. I love Ubuntu and it's community!

    Just like I was saying, serious overheating problem. The amount of machines I have seen with blocked air ways. It is just like getting a cold, if you can't breath, you heat up. I have even seen one with a melted chocolate bar blocking the fan vents!!!
    I suspect your machine will be fine but, probably has suffered stress on the components due to the amount of time it sounds like you have had the problem.
    If I was you I would still seriously think about getting a laptop cooler. At a few bucks it is really worth it.
    They can be slippy under the laptop depending upon which one you get so you might have to get some sticky rubber feet for the bottom of the laptop as well to stop it sliding.

    Have you tried the audio settings change as I suggested for your HDMI.
    It worked a treat for me and is probably all you need to do as well.
    Good luck again.

    I am not using HDMI out so you must be talking to the other person.
