Sub-12-Inch Notebooks from Fujitsu-Siemens Lifebook range


By today's standards all off these look bulky. They are way over 2cm thick, and have wide borders around the actual display. Heck, the 10.6" p7230's footrint is not even smaller than that of most modern 12" notebooks. Somewhat less wide, but higher. The p1510/p1620 are smaller, though. Weighing around 1.2kg/1.1kg they not really light either.
Performance ranges from bad (core2duo) to abysmal (pentium m), even compared to modern Atom processors. Oh, and many (most) modern (even cheap) Netbooks have much better displays, with full HD and IPS.
But then, the cases are very sturdy and well made. The keyboards are really nice to type with. The p1510/p1620 even have Trackpoint (i call that a plus, but ymmw).

Why such dinosaurs in 2k20?


I like the form factor, its more square (less wide but higher) than modern (sub)notebooks. Although it might use up a higher volume of space its often easier to fit into small bags and backpacks.
The Linux support is near perfect, much in contrast to (most) Atom based systems. Those often lack sound or video acceleration or WiFi.
And they are sturdy, have good keyboards. And a design i actually like. The battery is exchangeable. It has VGA, Ethernet and Headphone connectors as well as a docking port (not to mention Cardbus and Firewire). And i can fit an extra battery in the optical drive bay.
And its cheap. And that is important: i don't have to care about it. It can break, get lost or stolen and i don't really have to care.

Linux compatibility


Very good. Everything i tested so far worked flawlessly and out of the box with:
  • Artix Linux (Kernel 4.19.88 LTS) on the p1620
  • Arch Linux 32 (Kernel 4.19.23) on the p7230 (also OpenBSD)
  • SlackWare (Kernel 4.4.202) on the p1510

Suspend to RAM seemed to be stable on all of them, and the power consumption is ok (for what it is).
Not tested so far:
  • CompactFlash Slot on the p1510 Slot with anything but a Flash Card
  • SD Card reader with anything but SD cards. SDHC works fine.
  • Modem
  • Suspend to disk
  • Docking port

Touch Screen on the p1510


Needs to be initialized:
inputattach -fjt /dev/ttyS0

Note that the inputattach version from slackware does not work, i had to compile linuxconsoletools myself.
And it has to be calibrated:
Section "InputClass"
	Identifier   "calibration"
	MatchProduct "Fujitsu Serial Touchscreen"
	Option       "Calibration" "92 4020 110 4009"

I really do not remember how i optained those calibration values. Maybe xinput_calibrator (although its not installed, but eh), or maybe just try and error.

Touch Screen on the p1620


The Panel does not appear until after X is running form some seconds (not the faintest). Thus normal methods of calibration fail. I wrote a little script:
#!/bin/bash

echo -n "Waiting for touch device to appear"
while ! xinput | grep "Touch Panel Pen" &> /dev/null; do
        echo "."
        sleep 1
done
echo

echo "Oh hey! There it is!"

xinput set-prop 16 'Coordinate Transformation Matrix' 1 0 0 0 1 0 0 0 1
xinput set-prop 16 "Coordinate Transformation Matrix" 1.06666660308837890625 0 -.02624994913736979166 0 1.11411996309114024669 -.08534818541953944941 0 0 1

I got the calibration values using xinput_calibrator. Its output is in the wrong format. I found a script somehwre that does the transformation.

Tablet mode


In tablet mode, the screen is ofted used rotated. A handy little tool, x11-touchscreen-calibrator, deals with the necesarry coordinate transformation of the touchscreen. Sadly, its made for capacitive touchscreens, which do not need to be calibrated. Thus, it does a uni transformation, ignoring existing transformations. Here is hacky patch which loads existing transformations at startup. I intend to later polish it up and to a pull request. For now, it works:

Finding HDDs


The p7230 as well as the p1510 use a pretty rare form factor for their HDD: 1.8" in a case similar to PC-Cards. The interface is standard IDE/PATA, but the connector is more similar to a PC-Card. Most 1.8" PATA drives have either a ZIF connector or the more common small 44 pin IDE connector. The original 80GB TOSHIBA MK8007GAH in th p7230 (which mine was missing) is genuine unoptanium. Some older IPods seem to have the same format, and drives are plenty and cheap, ranging from 10GB to 60GB (i do not own one, so i never tested if those work). Later i got two p1510 with drives. One is now in the p7230 and works well there.
The only adapters for this odd Format that i could find where for CompactFlash Cards. Most of those have abysmal writing performance (some expensive ones might do better, but my SanDisk Ultra one did not).
Oh, and to make things worse: the optical drive in the p7230 is PATA, but connected to the chipsets SATA port via a SATA-PATA bridge. In 2019, i could find no PATA/PATA drive bays, only PATA/SATA. But using one of those is slow and buggy. Apparently SATA/PATA/SATA conversion does not work well.
The best i could find where "WD SiliconDrive II" CompactFlash Cards, which have really impressive ratings and are not too expensive. They are out of production and where only made up to 16GB, but used ones where sometimes on eBay for a decent price (at least in 2019, Germany). I got one of those for my p7230, but now use it in the one working p1510.
The p1620 is better in this regard, as it uses 1.8" drives with a much more common ZIF connector. For which, for example, MSATA Adapters are a thing.
