I can confirm this bug on my Dell Precision M4800 running: Linux ******** 3.13.0-45-generic #74-Ubuntu SMP Tue Jan 13 19:36:28 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux
The harddisk temperature gets too high that is around 50 degree Centigrades. I bought my laptop recently ( a couple of weeks ago) and installed ubuntu on it. I have looked over the internet at many forums and people are facing similar problem and I think this needs to be taken care of. It has been reported multiple times and confirmed by multiple people: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/394826 -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/399978 Title: Excessive heat versus excessive parkings Status in linux package in Ubuntu: Confirmed Bug description: If laptop's AC adapter is plugged in, the temperature of the hard disk increases very fast, up to close to 60 Celsius degrees, which is maximum, according to Western Digital specifications. and that happens without any apparent reason, I mean while browsing the Internet, reading online an article or writting emails. The number of parkings is almost constant in an hour. If the AC adapter is unplugged and only the battery is providing power, the heat is much lower, but the number of parkings is dramatically increasing, almost 15 in a minute (at each 3 or 4 seconds I can hear a click). I tried ACPI=off but it didn't help, in that case the heat was fast increasing even while running on battery only. I have a laptop Fujitsu Siemens (Esprimo Mobile V6545) with 4 GB RAM (one added by vendor), and Ubuntu 9.04 Jaunty. And for checking the above parameters, I used the commands: sudo hddtemp /dev/sda and respectively sudo smartctl -a /dev/sda | grep Load_Cycle_Count . It is so frustating that I think I can't let that continue anymore and try another OS. Please help. Thanks.
