Dorfl / Fujitsu-Siemens Lifebook P7120

Dorfl is a Fujitsu-Siemens Lifebook P7120 that I got for my consulting work. It is small, and with good battery life, so it is easy to carry to meetings, and on travels. This page describes setting it up with Debian.

General notes

On the whole, I'm happy with the laptop. It is quite small, but not so small that the keyboard is uncomfortable for my big hands. The touchpad is not very good so I tend to use an external mouse when at a desk, which never happened with my previous laptop. The screen is good. It is quite glossy, but this doesn't seem to make reflections from, say, sunlight through windows worse (it still makes the screen unusable, if there is a bad reflection). Battery time is up to about seven hours with two batteries, which is much worse than the advertised eleven hours.

Debian (testing/etch) works well on the laptop.

Driver support status

lspci -n outputs the following:

To get an idea of how well the various devices are supported under Linux, copy and paste the above to Kenshi Muto's device driver check page. At the time of writing this (July 2006), the output looks approximately like the table below (I've shortened it), but of course the status may change, as drivers are developed further. I'm not going to be updating this part of the page very often.

Batteries

I have two batteries. Number 1 is the one that comes with the laptop, number 2 is the optional one I have instead of a DVD drive in the drive bay.

After about six months, the batteries last around 5-6 hours, depending on usage.

Suspend-to-ram uses power. Overnight, during about 9 hours, the battery charge of the second battery went from 100% to 94%.

Checklist

Below is a checklist of the things I want to work in the laptop. It does not cover all of the hardware, or all the stuff the hardware is capapble of, because I have no use for everything. For example, I have no landline, and no dialup account at an ISP, so the modem is useless to me.

"OK" means it works, and I use it. "Bad" means it doesn't work. "Unknown" means I don't know if it works.

I've last checked things on this list on 2006-09-12.
