Using the HP Pavilion dv7-3127eg laptop with Debian GNU/Linux

HP Pavilion dv7-3127eg

Yep, so I bought a new laptop recently, my IBM/Lenovo Thinkpad T40p was slowly getting really unbearably sloooow (Celeron 1.5 GHz, 2 GB RAM max). After comparing some models I set out to buy a certain laptop in a local store, which they didn't have in stock, so I spontaneously got another model, the HP Pavilion dv7-3127eg (HP product number VY554EA).

Why this one? Well, the killer feature for me was that it has two SATA disks, hence allows me to run a RAID-1 in my laptop. This allows me to sleep better at night, knowing that the next dying disk will not necessarily lead to data loss (yes, I do still perform regular backups, of course).

Other pros: Much faster than the old notebook, this one is an AMD Turion II Dual-Core Mobile M520 at 2.3 GHz per core, it has 4 GB RAM (8 GB max), and uses an AMD RS780 / SB700 chipset which is supported by the Free-Software / Open-Source BIOS / firmware project coreboot, so this might make the laptop a good coreboot-target on the long run. I'll probably start working on that when I'm willing to open / dissect it or when the warranty expires, whichever happens first.

Anyway, I set up a page at randomprojects.org which contains lots more details about using Linux on this laptop:

Most of the hardware is supported out of the box, though I haven't yet tested everything. There may be issues with suspend-to-disk / suspend-to-RAM, sometimes it seems to hang (may be just a simple config change is needed in /etc/hibernate/disk.cfg).

Cons: Pretty big and heavy (but that's OK, I use it mostly as "semi-mobile desktop replacement"), glossy screen, loud fans (probably due to the two disks).

For reference, here's an lspci of the box:
