    Burn marks from laptop

    While inspecting my beloved body before stepping into the shower a few hours I discovered something terrifying. A few inches above the left knee I noticed dark burn marks. I spend quite sometime with my laptop(or is it a notebook?) in bed and since air vents are located on the left corner I can conclude anything else other than it's my computer which has caused the burn marks.

    Has anyone else here have burn marks on their bodies? What do you recommend me to do, can I return the laptop and get my money back, or a laptop with a C2D CPU instead? With this being said I discourage you all to buy a laptop with an AMD processor.


    My specs:

    dv9074ea
    17 inch
    Turion 64 X2 1.8Ghz
    Vista Home premium
    160GB
    1GB

    Switching to a C2D won't make that much of a difference. I take it you had the exhaust vent pointed directly at your exposed leg? That might be enough to cause first degree burns, maybe. Are you sure it isn't just bruising from the weight of the laptop?

    I could sit my dv9008nr Turion notebook on my lap for hours without incident, wearing jeans at least. I was careful not to block the fan intake and exhaust though.

    Umm..

    Usually when I burn myself, I feel intense heat and pain where I'm getting burned. That's just me though.. However i think that if your laptop burned you, you'd know for sure pretty quickly.. ;)

    Also, I really doubt the temperature of the air from the vents is hot enough to burn a person... the bed you were using it on would catch fire first.

    When I'm in bed I wear shorts or boxers and off course I move the laptop when it start burning really badly, so there hasn't been any protection for my leg. I live in California so I rarely wear jeans when I'm at home

    The heat coming from the exhaust is really hot after a while, especially if I'm multi tasking, running firefox, messenger, media player and doing lots of things at the same time.

    The marks are not bruising from the weight of the laptop because it ain't that heavy and further more it takes some very hard beating to bruise me. The marks are where the exhaust is point at when I'm in my usual surfing-with laptop-in-bed-position.

    It all feels really bad especially since use my laptop allot and I can't keep letting it burn my leg. I'll send HP a mail and see what they have to say about it.

    Dont call HP!

    It's pretty simple... Don't set the laptop on bare skin for any extended period of time because the exhaust will get extremely hot! Especially if you are taxing the processor!

    You're just going to have to find another way to use your laptop in bed, and I surely wouldn't recommend you blocking the exhaust port for any extended time either!

    It's not good for the machine.

    Sounds like it's where the vent was putting out the hot exhaust. Hopefully you're not diabetic 'cause they're less sensitive to heat and cold. I sometimes feel the bottom becoming uncomfortable and move the laptop often and when it's really unbearable I turn it off to cool down and minimize damage or use a usb powered cool pad.

    My CPU temperature is almost always at 80 degrees and peaks at 87 at times. Is that normal?

    87 C?

    I just reapplied TIM to my desktop and was asking the same questions about max heat. I was told that as long as it stayed below 65 C that should be fine. Someone mentioned getting theirs up to 70 for a short period of time, but not recommending doing that.

    I'd say upper 80s is pretty high. What program are you using to measure the temps?

    See what Core Temp says the temperature is. I know that program is accurate, many others don't read these notebooks correctly. 87C would be 188F which seems unlikely.

    It is possible that HP didn't mount the heatsink correctly. They've done that before. If the CPU temp really is 87C then send it back, note the CPU temp and suggest the likely fault. Technically you could remount the heatsink yourself and use Arctic Silver 5 for better-than-factory temps but that's very tricky and would void your warranty (if they notice).

    I would rather not see pictures of this guy's inner thigh burn marks. I think we would have to make this a pay site then ... lol.

    I'm not bull****ting guys. I have burn marks right above my knee. Here is a screen shot I just took to show you guys how hot my computer is during normal surfing. The fan is constantly spinning at high rpms, no matter what I do.

    Whoa, something is definitely wrong. The max core temp threshold on the TL-56 is 95C. That cpu is roasting.

    As was suggested above, it is probably not making proper contact with the heatsink. I would not use it until you rectify this situation, either by making the repair yourself or sending the unit back to HP.

    OK, that's broken. Now that I think about it, the problem is probably not merely a poorly installed heatsink. That wouldn't cause the hot exhaust. It could be a broken voltage regulator module on the motherboard, a broken power brick... send it back to HP and make them figure it out.

    I'm in Orange County at the moment and will be heading back to Sweden on Monday, so I'll contact HP when I'm back home.

    I just took at look at the burn marks again and they don't look pretty, neither do I know if they'll ever disappear completely. Somehow I believe I should be compensated by HP for this because with burn marks on my leg replacing my laptop isn't going to be enough.

    Regardless of product malfunction, I guess Its just hard to believe you wouldnt notice this as its happening, and move your leg right away and avoid the burn. :) *shrug*

    Ok, i now definitely believe that your laptop is seriously messed up temperature-wise (wouldn't the processor melt at that temp???? rofl) but I still dont believve the burn marks.


    lol... The amazing thing about the human body is its ability to heal itself... if you were burnt so bad that you actually think the 'marks' aren't going away.. then you would have gotten a 3rd degree burn, the nerves in your leg near the burn would be fried (you wouldn't feel anything), and you'd be in the hospital emergency room.. ;)

    Hey all, I believe the marks on your leg aren't actually burn marks, but the aftermath of a burn- the medical term is "erythema ab igne." Google it for more info. Does it basically look like a mottled red area that doesn't blanch (turn white like skin color) when you press on it? I have this on my leg from an Acer laptop I bought in August of last year. I got a burn from it right after getting it . . . you'd think you'd noticed getting your leg burned but when the computer is on your leg and the temperature is going up slowly, it's easy not to notice it until your leg is toasted- and none of the other three laptops i've had have ever burned me. The erythema ab igne results from continuing to expose your leg to the heat of the computer. I went out and got a laptop pad after getting burned but still developed this. I thought the marks would go away in time, but it's been almost a year now so I finally went to my PCP. She told me to go to a dermtologist, but there may not be anything that can be done for it. Hope this helps.

    Also, keep the laptop off your lap and use SPF 50 on the area if you're in the sun. According to my PCP, this can turn into skin cancer later on down the line if you continually expose the area to heat. You might want to make an appt with your doc to confirm the diagnosis and treatment needed.

    Wow, that sucks. Laptop usage could eventually lead to skin cancer...

    My core temps, are 31c and 35c respectively. I'd leave my machine off if I were you or you are going to fry the motherboard.

    Think on the bright side, at least it was your thigh and not another body part in your general lap area.
