WinXP laptop temp question
Just a general question about laptops. Is it ok for some laptops to have a
port connector (for example) get so hot it's uncomfortable to touch? I have a Dell 830, 2.4 GHz model, where the back Ethernet jack is too hot to leave your finger on for any length of time. The other reported temps by CPUID are good I think (under 40 C), the hottest recorded temp being the NVIDIA NVS 140M video, at 54C. And surprisingly, the laptop fan is pretty quiet. I've just never expected this, but have limited experience with computer temps. TIA. |

Is the laptop battery life shorter than normal ? Or does the Ethernet connector only get hot while the laptop is charging ? Paul |

Paul Ah, I see where you're going; either impending-failing battery (check by running the laptop for a while with the battery removed - does it get warm?), or poor connection at the power socket (these can get _very_ hot before they fail altogether) (check by running on the battery for a bit - does it get warm?). -- J.

Coincentally or not, this is the same laptop that I lost the double USB port in a few days ago (which is located in the same area as the hot spot), and was never able to resurrect (via any device manager uninstalls and reinstalls, etc). That double USB port was apparently damaged at the hardware level, which I still find hard to believe. |

Though don't short anything.) I don't know whether it was hot before, or that could have answered it. :-) I don't have such a thermometer, but I can tell you this much: if you leave your finger inside that metal port for about 5-10 seconds, you will need to pull it out. :-) Paul seemed to be suggesting that might be around 65C. I just looked this up on the Internet, and according to one article, it says 60C (for up to 5 seconds). I'm not sure if anything inside the laptop is supposed to run that hot, but maybe it could (it does have a NVIDIA graphics chip, afterall). Oh, and I did check it out with the battery removed, but got the same result. |

Though don't short anything.) Do you need a thermometer though, if the owner knows how hot it ran new, and it's running a lot hotter now ? If some circuitry in the same area melted, you'd want to have a look inside, to see if the thing could be saved. There are sites that have take-apart guides for a few laptops. You can't always find the exact model you want though. https://www.ifixit.com/Guide/Dell+La...lacement/29140 Paul |

Paul Well, like John was saying, I think it's hot because its near some metallic part of the motherboard that runs a bit hot, and since it's metal, it's just conducting heat from that point (and the neighboring port is also pretty warm). But the whole lower right hand side corner of the laptop is pretty warm. (I don't think the battery life is poor, but I haven't checked it, and these ports or jacks happen to be on the right hand corner of the laptop). 65C is when you can't hold your finger on it for very long (meaning like 5-10 seconds)? I was thinking it would be a lot less than that. |

I've just never expected this, but have limited experience with computer temps. TIA. It's _probably_ OK, but I'd be concerned too. In a similar condition (the part of the case to the left of the tab key a bit hot to the touch on my Toshiba Portégé), I obtained one of the vacuum fans that goes on the side vent and sucks (better than the trays that blow from below, IMO), but then I'm a bit paranoid as my last machine died from overheating. Worth making sure the vents aren't clogged - both inputs (usually underneath) and outputs (usually side, probably near your hot port connector). If you do decide to add a fan tray, two things: firstly, find where the hot spot in your laptop is, and - especially if it's a tray with only one fan in it - make sure it's in the right place (note: it _won't_ be in the middle); and secondly, don't get one with no bottom cover or one with _large_ vents. Why? Because you can't put it on your knee (lap) - the fan stops when it presses on your knee! The side-sucking fans, though I think more effective, make the laptop shape more unwieldy. (And getting the rubbery "lips" that come with them to fit properly over the vents is fiddly.) I have the TecBean one with a temperature readout (currently showing 32). -- J. P. Gilliver.

WinXP laptop temp question
I've got one other question on this (somewhat hot) laptop issue, which I'm
still trying to investigate. If one turns off all extraneous devices in BIOS, does that in any way impact the total power consumption (and thus heat) at the hardware level? I'm just wondering if disabling all the devices not being used in BIOS (and perhaps windows), such as Bluetooth, Serial and Parallel Ports, PC card ports, docking tray, etc, will literally (at the hardware level) turn OFF some IC chips, and thus reduce the overall temps and power consumption. |

In theory, it should disable the chip select, rather than gate off power to the chip. You would have to inspect individual chip datasheets to see what leverage is available in them. Some of the chips will have their own handler module in the BIOS code. And it's easy enough to check. Remove the battery. Connect the power adapter to a Kill-A-Watt meter (P4400). http://www.p3international.com/products/p4400.html Now, under quiescent conditions, turn off the items in question, run the OS, and see if there is any measurable difference to the total laptop power. And the WinXP OS is ideal for this - Windows 10 would swamp out any attempt to do experiments, by driving the power consumption all over the place. When you plug in the network cable on my laptop with Win10 running, the power about doubles. It has a picnic for itself. The CPU, GPU, chipset, DIMMs should draw the most power. A little Firewire controller chip might be a watt when it's busy, or less than that when not doing anything. Ethernet is about a watt. No idea on Wifi. Really old PCs (year 2000) run at almost constant power. There's hardly any savings on those. Newer machines have a larger power swing between quiet and busy. Paul |
