Hi there! Are you sure this is Linux/Ubuntu related? The Dell Vostro 3700's cooling system is basically broken. Over time dust accumulates on the fan protection cover, preventing hot air from escaping. Applying the latest bios updates helps some but it basically just increases the fan's activity. Hiding the actual problem behind more noise. Unfortunately this will not work forever and eventually the fan will need to be cleaned. The only solution to this problem (since the Vostro 3700 is out-of-warranty) is to manually untie all the screws on the lower part of the laptop until the cover comes off. Then you have to untie all screws on the motherboard and flip it around. Then use a tiny screwdriver to open the case of the cooler and vacuum the inside. Put the entire thing together again afterwards. You'll notice right after starting your laptop that the cooling sound is much less dull (Is this the right word?) than before.
A step-by-step reference is given here: http://support.dell.com/support/edocs/systems/vos3700/en/SM/Heatsink.htm just follow _all_ the guides linked to up to step 12. Now, instead of disconnecting the heat sink, open up the fan and clean it. Then do everything in reverse to re-assemble your laptop. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/689571 Title: cpu runs very hot even when idle To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/689571/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
