While Slackware, and pretty much any Linux distribution, out of box, might be geared for any PC out there, there are some packages not provided by default for laptops you may wish to download, build, and install to help with things like power consumption, fan/heat issues, etc.

Laptop-Mode-Tools is one such package you should get if you run any laptop.

It and various other packages, are found easily at http://www.slackbuilds.org which contains links to build scripts and sources exclusively for Slackware users and admins.

I also recommend if you use an Nvidia or AMD video chip, to download the Proprietary drivers for your chipset and install them. AMD's installer has instructions for Slackware already and Nvidia drivers can be obtained from SlackBuilds website also.

Also, it's just the nature of some laptops to just run hotter than others, especially high-end, gaming, and professional models.

Run 'sensors' and check what part is getting hot?

Does this happen all the time, as in after a clean restart, or is it only after you resume from a suspend? What kernel version are you using?

By default, CPU frequency scaling is turned off if your laptop is plugged in.

To change that, edit /etc/rc.d/rc.modules and change "CPUFREQ=battery" to CPUFREQ=on".

Hi,

Open the laptop and check for dust bunnies in the fan outlet.

On CPU load 100% its normal for laptop to have high temperatures. For example I have one laptop working with 100% load all the time. CPU temperature 75 degrees. And also CPU's that are made for laptops can handle higher temperatures than desktop ones. For example Intel mobile CPU's can handle upt o 102 degrees I think. It is listed in CPU datasheet.

I have the same problem (I opened a new thread and I didn't find this one). I installed laptop-mode-tools and when executing powertop almost everything is in "Good". However, temperature is still the same... 80ºC or so. Will I have to go back to Window$?

No.
Check for dust in the fan area. Also, I use one of these, take a look - Laptop cooling pads

Regards.

Do you have the proprietary video drivers installed? Which hardware is in that machine?

I probably have the propietary drivers installed. I don't really remember. However, I have a graphic card that uses the Optimus sh*tnology, but I chose to only use the Intel GPU, and I made sure at installation time to install them (maybe they're not modprobed [do they have to be even modprobed?]). Regarding my hardware, there you go:

Code:
bash-4.2# lspci 
00:00.0 Host bridge: Intel Corporation 2nd Generation Core Processor Family DRAM Controller (rev 09)
00:01.0 PCI bridge: Intel Corporation Xeon E3-1200/2nd Generation Core Processor Family PCI Express Root Port (rev 09)
00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09)
00:16.0 Communication controller: Intel Corporation 6 Series/C200 Series Chipset Family MEI Controller #1 (rev 04)
00:1a.0 USB controller: Intel Corporation 6 Series/C200 Series Chipset Family USB Enhanced Host Controller #2 (rev 04)
00:1b.0 Audio device: Intel Corporation 6 Series/C200 Series Chipset Family High Definition Audio Controller (rev 04)
00:1c.0 PCI bridge: Intel Corporation 6 Series/C200 Series Chipset Family PCI Express Root Port 1 (rev b4)
00:1c.3 PCI bridge: Intel Corporation 6 Series/C200 Series Chipset Family PCI Express Root Port 4 (rev b4)
00:1d.0 USB controller: Intel Corporation 6 Series/C200 Series Chipset Family USB Enhanced Host Controller #1 (rev 04)
00:1f.0 ISA bridge: Intel Corporation HM65 Express Chipset Family LPC Controller (rev 04)
00:1f.2 SATA controller: Intel Corporation 6 Series/C200 Series Chipset Family 6 port SATA AHCI Controller (rev 04)
00:1f.3 SMBus: Intel Corporation 6 Series/C200 Series Chipset Family SMBus Controller (rev 04)
01:00.0 3D controller: nVidia Corporation GF119 [GeForce GT 520M] (rev a1)
02:00.0 Network controller: Broadcom Corporation BCM4313 802.11b/g/n Wireless LAN Controller (rev 01)
03:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI Express Gigabit Ethernet controller (rev 06)
I was thinking of doing a fresh install again with less pkgs since I installed 99% of the system, and there must be things that I don't really need. Now that I can administer pkgs myself I feel more confident with Slack.

You definitely need the proprietary drivers, most likely it is the Nvidia GPU that heats up your system. Also, have a look into your BIOS/UEFI if you can disable the Nvidia GPU.
Luckily, Nvidia is working on making Optimus usable on Linux, so this will be a solved issue in the future.
