Media Bay with half-ejected CDROM drive

Front (note the curve)

Back (shows connector)

Naked CDROM drive. Floppy looks very similar.

Car PSU

Power Supply for car. I was extremely fortunate to see this item on an auction web site. Unfortunately its the older model and does not take a 24 V input (whereas the new one takes 12V-32V input.) This PSU is much less taxing on energy than my former arrangement of a 12V->240V inverter then the normal wall adapter. Full credit to llpwr for the design of this unit.
Zoom of ethernet and modem sockets for Matthias Pfeifer

The gunk you can see on the grey plastic is 5 minute araldite glue. I had a lot of cracking around the screen mounts and my screen was getting floppier by the day. There are only four piddly little screws holding the screen on, and two of them are just into the grey plastic. So thats how I fixed that problem. The hinge cover (above the modem socket) is held on by sellotape.... I didn't want to glue that down permenantly.

Specifications

This is the hardware:

CPU: Intel Pentium III with SpeedStep

RAM: 256 Mb PC100 (maximum)

Video: 4 Mb ATI Rage Mobility P/M 2x AGP device

Motherboard Chipset: Intel PIIX4

HDD: 27 Gb Fujitsu 2.5" IDE (standard was a 10 Gb IBM Travelstar HDD)

10/100 Mbit PCI wired NIC, a 3COM 3C905-TX (Tornado) using the 3c59x module and the cardbus PCMCIA interface

10/100 Mbit PCMCIA wired NIC, an Argosy EN-225, using the pcnet_cs module

11 Mbit 802.11b wireless NIC, a Dlink DWL-660 16 bit card, using orinoco_cs module

22 Mbit 802.11b wireless NIC, a Dlink DWL-650+ cardbus card, using the acx100 module (not part of the linux kernel)

54 Mbit 802.11g wireless NIC, a Dlink DWL-G650 cardbus card, using madwifi module MAD Wifi project

External CDROM (Teac CD-224E, part number 3489D )

External Floppy Drive

Spare Battery

Weight: 1.66 kilograms for the machine and battery, 420 g for the PSU/cable.

This laptop has to be seen to be believed - its massively tiny. When I bought it from an auction house I did a paper cutout the same size, and marked the thickness measurement on top. Then I compared that to my existing laptop (a Toshiba Satellite 4030CDT) The difference was about 3 cm on the width and depth, and the thickness is 26 mm compared to 50ish. That simple statement does not demonstrate the "tinyness" of the Dell. It's positively weenie!

The floppy drive works perfectly, and can be plugged after booting. There is no space in the machine for either drive, so one has to plug them in the rear. The CDROM drive plugs into a special connector with about 45 pins on the rear, while the floppy drive can use either the CDROM plug/cable or a special cable for the parallel port. Just don't access the floppy drive if its not plugged in else you'll get lots of weird messages , and don't attempt to plug the CDROM into the parallel port (even though the plugs fit you'll destroy the CDROM drive.)

The default CDROM drive is a Teac 24 speed, with a weird curvy face plate to fit the front of the larger Dell Latitude series. You can use a conventional laptop CDROM drive but the results will not be astheticly pleasing. I have butchered a 24x CDR/DVD drive into the holder, but I could not get the curved face plate to line up.

The purple keys seem to mostly work without any OS assistace. Strangely, the OS doesn't even see them... xev reports no keypresses when using the purple Fn modifier key. Here's my results...

Key Name	Key	Function	Works?
Suspend	Esc	Suspends laptop?	No response
Blank Screen	F1	Blanks the screen and turns off the backlight.	Works fine - touch a key or the mouse to wake up. This key is not labelled on the keyboard.
Battery	F3	Displays battery stats in top left corner "BAT 55% UNKNOWN AC OFF"	Works - do a "Battery Calibration" in the BIOS to get an estimated time remaining.
Volume Up/Down	F5 and F6	Change volume	Works
Font	F7	?	Does nothing in Linux, X or frame buffer console
LCD/CRT	F8	Toggle screens between Internal, external, and both	Works under windows, but linux ignores this. NEEDS WORK TODO
Pad Lock	F9	Number Pad Lock	Works (nothing to do with security)
Scroll Lock	F10	Stops scrolling	Works (depends on Operating System)
Pause	F11	Pause output	Works (depends on Operating System)
Break	F12	Kinda like Control-C	Works
PrtScrn	Home	Various	Works
SysRq	End	Various	Works
CD Eject	E	Eject CDROM drive	Works fine - if you hot-swap the CDROM drive, you need to run hotswap as root under linux to pick up the new drive without rebooting.
Brightness	Arrow up and down	Adjusts LCD brightness (not external)	Works fine - 12 steps
Home	Pg Up	Start of line	Works
End	Pg Dn	End of line	Works
Numeric Keys	Various	Type lots of numbers	Works - however the skew of the keys arrangement is off-putting.

Not Working Yet

These are the niggles I haven't fixed yet... Always work in progress

FIXED The touchpad works, but I can't tap with it. Win98 taps fine, so its not a hardware issue. I need to play around more with the XF86config file. UPDATE Fixed. Turns out that a debian update just fixed it. BTW installing the debian synaptics driver packaged as xfree86-driver-synaptics totally broke it.
Suspend to disk - needs a 262 Mb partition first on the drive (ie, hda1) and I don't have that. UPDATE I do now - must try it at some stage.
Modem - Bloody winmodem from Lucent. I don't have a dialup account anyway, so can't try this.
Kernel support for Dell Laptops doesn't seem to like this one. I've even tried --force installing the i8k module... but it just complains
```
i8k: unable to get SMM Dell signature
i8k: unable to get SMM BIOS version
```
More to do on this, including looking at the i8k source.
UPDATE try a "modprobe i8k force=1" to ignore checks for a supported system. dmesg says this for mine in kernel 2.6.8.1:
```
Dell laptop SMM driver v1.13 14/05/2002 Massimo Dal Zotto (dz@debian.org)
```
however catting /proc/i8k returns incorrect values...
```
thionite:~> i8kctl 
1.0 (null) ZNXN31S -1 -1 -1 -1 -1 -1 -1
thionite:~> cat /proc/i8k
1.0 A09 ZNXN31S -22 -22 -22 -22 -22 -1 -22
```
FIXED Low Battery and Out-of-power warnings - it just dies. I'm now working on 2.6.11.12 and I simply cannot get any of the cpufreq modules to work. It could be that this Dell is too old. UPDATE I've toged the dsdt table and removed the errors, but the machine still doesn't play nice with acpi. Pressing Fn-F3 shows the estimated battery, but speedstep does not work. This is apparently because the "model name: Pentium III (Coppermine)" line in /proc/cpuinfo shows this CPU is not supported by the linux speedstep code. Bugger! You need a "model name: Intel(R) Pentium(R) III Mobile CPU 1000MHz" type CPU.
UPDATE This arrived from Gordon Farquharson
```
I also have a Latitude L400 running Linux. Your L400 page helped me out
when setting it up. I thought that you may like to know about a possible
resolution to the speedstep-smi issue. Check out:
```
http://bugzilla.kernel.org/show_bug.cgi?id=5553
FIXED I've now upgraded to 2.6.17.6 and things are working better. Mainly SpeedStep works out of the box! Check the dmesg section. I have not needed to install cpufreqd or any other userspace module.
Lid switch just blanks the screen and leaves the laptop running at normal speed. (Kinda good and bad.) It means I can go home with the laptop on.
FIXED xine crashes if the extmod kernel is loaded in XF 4.3.x This is a known bug with ATI video cards... this one is an ATI Rage Mobility P/M AGP 2x card. The fix is to comment out the extmod line in XF86Config-4, at the cost of this message from xine and opera:
```
thionite:/data> xine somefile.avi
This is xine (X11 gui) - a free video player v0.99.1.
(c) 2000-2003 The xine Team.
Xlib:  extension "SHAPE" missing on display ":0.0".
Xlib:  extension "XVideo" missing on display ":0.0".
```
I've since upgraded to xorg 7 and this is all Just Working Now.

Audio

Audio is working - the controller is a Cirrus Logic Crystal 4281 PCI device and uses the snd_cs4281 module, in kernel 2.6 and later.

The speakers are poor and really only suited to bingbong noises... use headphones for any real work. Suprisingly the speakers are hidden - theres no grille at all over them. They are between the battery and the keyboard according to the Dell assembly diagram linked above.

Also, recently I have acquired two port replicators... one for work and one for home. I notice that when the laptop goes onto the base the speakers can make popping and beeping noises until I either mute the sound, or reload the sound modules with a script like this:

rmmod snd_pcm_oss
rmmod snd_cs4281
rmmod snd_rawmidi
rmmod snd_ac97_codec
sleep 1
modprobe snd_ac97_codec
modprobe snd_rawmidi
modprobe snd_cs4281
modprobe snd_pcm_oss
aumix -L

This is irritating, cos theres no way to automate it. No event or signal is generated when the dock is attached or removed.

USB

USB is working fine - one USB 1 port on the left goes fine for me. I've used my USB lamp for nighttime geeking, a USB sony camera, and a four-port card reader.

For some reason linux thinks theres two ports - maybe one is on the port replicator.

Speedstep

I've had good and badness wrt speedstep. A nice fellow named Gordon Farquharson said this for kernel 2.6.16.1 :

I also have a Latitude L400 running Linux. Your L400 page helped me out when setting it up. I thought that you may like to know about a possible resolution to the speedstep-smi issue. Check out:

http://bugzilla.kernel.org/show_bug.cgi?id=5553

Power

APM and ACPI are both functional with this laptop. However I have lots of learning still to do.

The lid switch only turns off the display and the backlight... it doesn't shut the machine off. You can also press Fn-F1 to turn off the monitor.
The suspend key doesn't do anything.

There are no warnings when the battery life drops. All you see is the power charge light go yellow at 10% remaining, then start blinking at 5% remaining. However:

thionite:~> acpi -Vc
     Battery 1: charging, 32%, 00:48:36 until charged
     Thermal 1: ok, 60.0 degrees C
  AC Adapter 1: on-line

Or when discharging acpi returns this:

     Battery 1: discharging, 100%, 02:57:09 remaining

And when the fan is running acpi returns this:

     Thermal 1: active[1], 72.0 degrees C

I'm now running 2.6.11.12 and this behaviour has changed. You can use acpi to turn on or off the fan. I'm not sure what the values represent... more testing required.

thionite:/data# echo -1 > /proc/acpi/fan/FAN0/state
thionite:/data# cat /proc/acpi/fan/FAN0/state
status:                  on

thionite:/data# echo 3 > /proc/acpi/fan/FAN0/state
thionite:/data# cat /proc/acpi/fan/FAN0/state
status:                  off

Value	Resulting fan behaviour
-1	Turn FANx on - no thermal sensing. My CPU dropped to 35.0 degrees C. Fan is fairly quiet.
0	Turns FANx on - Seems the same as -1
1	No response
2	No response
3	Turns FANx off if on. NOTE I don't know if this turns on thermal sensing again.
4	No response

The Thermal information from acpi -Vc has changed too. Note the temperature is only accurate to round numbers.

     Thermal 1: ok, 36.0 degrees C

You can also press Fn-F3 to display some info in the top left corner of the screen.

Swapping batteries confused my machine on an older kernel. It said silly things like this:

thionite:~> cat /proc/acpi/battery/BAT1/alarm

Now it says this:

If anyone has suggestions for extending the battery life (especially raising that "last full capacity" figure I'd really appreciate it. My two batteries were 2622 and 1882 mAh when I got the machine (about four years old) and after a year they're at 1775 and 1423 mAh.

UPDATE I bought a new aftermarket battery for my L400. The "remaining capacity" for my old battery was only 611 mAh. Here are the same files from /proc/acpi/battery/BAT1/

UPDATE Woot! Alex Korchagin is a champion! With his advice I got CPU scaling working. Here's his advice:

Then compile all that stuff and reboot ;)

When you reboot, run "depmod -a" -> this will update modules' dependencies..

To enable speedstep add this line to your system startup script:
    modprobe speedstep-smi smi_port=0xb2 smi_cmd=0x82 smi_sig=1
Your speedstep is now enabled! Check it out with "cpufreq-info" command.

There are special utilites called "governors" which scale your bus speed
automatically. I don't use them.

I have 2 scripts which control speed:
ethereal ~ # cat scripts/full
echo 700000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_setspeed
ethereal ~ # cat scripts/empty
echo 500000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_setspeed

And I use them when I want to. You can use governors if you want..

p.s. don't use throlling (from 0 to 7, you wrote about it), it only slows the
machine and doesn't save any power :(

The cpufreq utils referred to are packaged as cpufreqd and cpufrequtils in debian. cpufreqd deals with governors automatically for you if you want CPU scaling handled that way.

Parts related to this machine

Optional parts include spare batteries and PSU, the Advanced Port Replicator (APR), external floppy drive and CDROM drive, external protective "Media Bay" shell for the floppy drive and CDROM, and any number of USB and PCMCIA devices.

I have now acquired a CDROM drive. You can hot-swap it in windows using standard windows methods, and in linux I have sucessfully used the command hotswap to tell the machine to rescan the IDE bus, where it picks up /dev/hdc fine. However after doing this, the machine will not reboot. Instead it sits at the POST screen and sulks until you power cycle it.

This model is also sold under the name "Gateway Solo 3300"
