Probably the main reason I consider HP Pavilion laptops worth buying is that they can be opened and disassembled very easily. This enables you (or your local computer repair shop) to perform a whole set of maintenance activities and to upgrade most parts without needing to send the laptop to some far HP authorized center. This post contains pictures of all the disassembling process I performed on a friend’s HP Pavilion DV6000 series laptop in order to replace its noisy faulty fan. You may click on each picture to enlarge it.
Benefits of this capability are:

Today I’ve found this page, I have to admit this guy is indeed clever!
Laptop Cooling. It is the strangest thing that all laptops have the same design fault. If operated on the “lap”, the needed cooling will be blocked off, it will overheat, and may eventually abruptly halt. Here’s how I modified mine so the machine would cool properly.

Although you can use K9Copy to extract the audio track from DVD some times is more convenient to use the commanline.
Ripping the sound track of a DVD movie through the terminal can be achieved using transcode and lsdvd commands.

A partire dalla versione ddi Ubuntu Karmic 9.10 il nuovo gestore dell’avvio GRUB2 viene installato di default sulle nuove installazioni (non negli aggiornamenti).
GRUB2 presenta una serie di miglioramenti, tra cui il supporto nativo per una varietà maggiore di filesystem, una configurazione modulare, il supporto per il ripristino automatico delle impostazioni in caso di necessità e, appunto, il più sfizioso: il supporto per immagini di sfondo ad alta definizione.

In Ubuntu Karmic 9.10 the frequency scaling GNOME applet always requires a password in order to allow you to change CPU frequency or governor. This is due to policykit profiles enforcing some more strict security.
Helas these profiles are not editable trough the applet in System -> Administration -> Authorisation.
Fortunately, as always in linux this can be achieved by simply editing a text file:

If you get the following error at login
The panel encountered a problem while loading OAFIID:Glipper
that means your computer if pretty fast and glipper loads too fast. The workaround consists in slowing down glipper starup a few seconds.

If you are used to customize your GNOME desktop environment according to you needs you would probably end with a too much populated “open with” contextual menu. When you right click on some ODT, MP3, AVI or whatever file you could end with several duplicate entries for Okular, Audacious, VLC, Brasero etc. Getting rid of them is pretty easy once you know the reason why they are over there.

There is a very simple command that reinstalls all the distribution packages and reconfigures them automatically. This is particularly helpful when you have done a partial upgrade and eventually have broken the system dependencies tree.
sudo dpkg-reconfigure -phigh -a
since this command would take a lot of time to process (~1 hour) depending on your hardware in case you have a minor dependency problem you can fix it via
sudo apt-get install -f
Code:
sudo dpkg-reconfigure -phigh -a
As I watched, every single package was stopped, reconfigured, and restarted. This process took the better part of an hour and a half, since it was effectively the same as re-installing but using packages that already existed. It finally completed and dumped my back to a command line. I rebooted into recovery mode, selected “try to fix X”, rebooted, and, to my untter amazement, Ubuntu had repaired itself! I was restored to a completely functioning desktop with the upgrade installed!
My point, is, if something gets broken during an upgrade, it looks like there is not too much that this command cannot fix. So, before you give up and reinstall (like I was about to do), give it a shot! It might work for you, too.
