How old is this laptop and when was the last time you blew out the heat sinks of dust? I saw one link saying May 25 of 2011 for its release, so it could be over a year old and if its never been cleaned this could be the problem. if you don’t know how, please ask more questions.
After you have taken a look a the dust issue, which is a problem on older probooks would you give us a the full hardware spec of the laptop.
I have a probook 4520s i3 cpu, no heat issue with that intel core on opensuse. I have had issue with ATI gpu’s generating to much heat on other hp laptops however, the good news is there is a simple fix for that.
In stalling this driver should allow you to get the heat under control.
The fix for the second issue involves installing the “ATI Proprietary Driver” which can be less than fun to put it mildly. If there is any way around this I would love to hear about it, the open source driver is working beautifully in 12.2 and I would love to use it exclusively. This said while searching for a fix for the sleep and hibernation issue I found this solution to the problems with installing the proprietary driver.
ATIupgrade is a script that helps automate the selection and installation of the proprietary driver. The automation of the driver revision number selection process is probably the best part of this script. Why? because selecting the right revision of the driver for your hardware is probably the most important part of the hole install process as far as Linux is concerned. Get it wrong and terminal login better be your preferred user environment.
That said download the atiupgrade rpm install it and follow the instruction on the webpage linked above. Once you have installed you can sleep, hibernate, and adjust your screen resolution to 1360x768 fixing the first issue as well.
Just to be clear using the open source driver when possible is easier, this stems from the proprietary drivers tenancy to break after a kernel update.
Did you find a solution to the heating problem? Was it a cleaning issue or the manufacturer issue (AMD)? I have a probook 4330s with i3-2310m + intel hd 3000. No heating problems at all in that one. I am thinking of upgrading to either HP probook 6460b (AMD A8-4500m 1.9Ghz) or HP probook 645 G1 (AMD A8-4500m 1.9Ghz). Both have the same processor, but the newer one (645 G1) is thinner. Any experience of whcih one stays cooler in the base?
I have the same problem with my laptop,it overheats and then shuts down. Imho Leap has nothing to do with that but mostly your usage. Place you laptop only on solid surfaces such as desks etc and not on your bed or overlapping materials. To keep track of your temperature:
