Looking inside my laptop, I noticed:

An empty slow with wires

An empty slot with wires

I noticed an empty slow with two wires. I believe those are inteded to install a 3G module. There is a SIM slot behind the battery. Looking at my laptop’s (HP EliteBook 8530w) data sheet, the appropiate 3G module is an HP un2400. It’s available on ebay for US $13.58 + $2.89 shipping. According to google that’s about € 12. For that price i’d say it’s worth a try.

Looking at the datasheets of my other laptop’s (HP EliteBook 8570w) data sheet, the matching 3G Module is HP un2430. This is also available on ebay, but it’s a little more pricy: US $ 53.99 + $2.99 shipping. For that price, I say no thanks!

I mean, I don’t need it at all, but it would be a nice toy to play with. So, I wonder, would the cheaper un2400 also work in the new laptop? According to this thread on the hp forums it might be blocked by the BIOS. Damn, that would be a nasty trick to make people buy the expensive 3G card. I mean, what the fuck? The thing performs the exact same task, why it is 4 times as expensive?

So… I might buy that thing some time, and test it in both laptops. Who knows… but I will also be looking for an optical drive to use in the “upgrade bay” of my 8570w. I mean… a laptop without an optical drive feels kinda incomplete.

As I have mentioned before, my HP EliteBook 8530w has been experiencing overheating problems, which I expected to be related to dust. Undusting this laptop went easier then anticipated.

Step 1: Remove the keyboard screws, located at the bottom

Step 2: Unlock the keyboard locks, located at the top of the keyboard, between esc and f1, f4 and f5, f8 and f9, f12 and scroll lock/

The keyboard looks a little dusty on the back, however, the fan doesn’t look as dusty as expected. Appearances are deceiving.

Step 4: Remove the fan

As you see, there is a thick layer of dust at the air outlet of the fan, even though the fan blades are just a tiny bit dusty.

Now that thick layer of dust is removed, put everything together again in reverse order ;)

Now…. I am running the laptop at full speed (2.8 GHz in stead of 800 MHz) and make it compile stuff, to see if the overheating problem is solved.
