 So why this is working this way? Is my dock or laptop failing? I'm not sure how it is related. It is not related to the video screen update, after moving cursors, as problem doesn't happen when using external USB mouse or when playing movies, or updating screen when typing on keyboard. It isn't also bigger current consumption, and this doesn't really happen when jumping from 800MHz to 1.7Ghz, at least I think so.
 Maybe it is power consumption, maybe some cabling is bad?

 I have an X41 Tablet on the way and am very disappointed that the only "Dock" available is more like a glorified port replicator. While I'm sure the X41 Tablet wouldn't ''fit'' on the Dock II, do you think it would be possible to remove the docking port from the plastic and connect it to the X41, or is it a different style connector? I would really appreciate audio jacks and a PCI slot.

		+	Ok. It is me again. It is possible to unplug linux definietly. It is also possible probably to plug it back, but only if kernel was booted with laptop docked in. This is because Linux uses resource assigned as assigned by ACPI / BIOS. If you boot to Linux kernel without being docked, and then try to dock, you will basically have problems with BAR, and kernel will say there is no enough resources, like virtual memory, IO ports, DMA channels or interrupts lines.
		+
		+	As of unpluggin, you need to unmount filesystems, make sure other processes (like smart, hddtemp) doesn't use disks, rmmod modules of controler and cdrom/floppy drive, then power down a particular PCI bus, I do not remember how it is done. And can undock it. In fact it can be scripted, and added as even handler after pressing undock button (and give some success or error sound when it is done, to notify user).
		+
		+	As of pluging things back, you basically need to rescan PCI bus. This is done by echoing something to scan file somewhere under in /proc or /sys/bus/pci. I would need to check. Then modprobing modules. It will however will not work, becasue sure, devices will be detected, but kernel will have problems with some PCI cards, which uses DMA or IOport. However, if you booted with kernel in dock station it may work.
		+
		+	It may be possible to reassign resources, or make kernel aware that we may need to additional resources in the future, which are not present at boot time, and declare its size, to make use them on docking time. I was searching some linux kernel mailing lists, and there was some discussions on it, but nobody had similar problem.

		+
		+	This is really strange but real.
		+
		+	Every time I move a mouse cursor using trackpoint a fan inside Dock II spin up significantly to be quite loud. Spinning stops exactly in a moment I stop touching trackpoint. If I just shake a mouse cursor it start, when I shake it more, or move it around faster, fan also becomes louder. When I have trackpoint point constantly in one direction it is also spinning fast. It stops spinning (became really quite) only when trackpoint is at rest (I can have a finger on it).
		+
		+	I know this behavior of my dock for some time.
		+
		+	When I use keyboard, or press mouse buttons (when when pressing them constantly), no such issue arise.
		+
		+	I just discovered also that using touchpad makes same problem! Even touching it and not moving at all will make fan spin faster. After stopping using touchpad, it takes about 2-3 seconds to make fan quite again. Left button doesn't do anything when pressing or depressing. However pressing right button makes a fan lauder for a moment, then stops, and same happens when depressing (fan is louder for a moment, and then quite, like 2-3 seconds).
		+
		+	So why this is working this way? Is my dock or laptop failing? I'm not sure how it is related. It is not related to the video screen update, after moving cursors, as problem doesn't happen when using external USB mouse or when playing movies, or updating screen when typing on keyboard.

+I have never had a dock with PCI integrated, but as far as I know all you should have to do is umount the filesystems and wait a second or two for the buffers to get flushed. Everything else *should* handle hotplug just fine. Certainly you should not be able to damage the hardware as it was designed as a hotplug solution, as long as it allows you to unplug ;-) Personally I would test it with a HDD without important data first to make sure your not causing corruption.
-I was comparing [[ThinkPad Dock|ThinkPad Dock (aka Dock I)] and [[ThinkPad Dock II]], and essentially they are the same. So what are the actual differences? The both pages mentions few common laptop models (T30, T2x, A2x, X3x). Actullay compatibility-wise, Dock II have same supported ThinkPads as Dock I, and additional T4x and R5x. However this means that all of them have same dock connector, right? And actually T4x and R5x will fit into Dock I? Will it work (unofficially)? I am just speculating. Probably When Dock I was released there was no T4x and R5x laptops on the market yet, and when they were released, specification and compatibility was not reevaluated. However, this just makes me think so what for really new Dock II was introduced? Was some problems of Dock I fixed in this new model?
+You can also write scripts to automatically trigger on dock plug/unplug. Unfortunately the unplug event will be too late as the device will already be unplugged, but the plug event may be handy... I used these udev events to automatically configure external monitors with xrandr.
-So how it is possible that in summary "Negatives: ..., less compatible", when it fact it looks to be more compatible? I think it is more compatible, just some functions will not work in the older models (like DVI, which also doesn't work in other port replicators with old laptop models) . --[[User:Baryluk|Baryluk]] 22:50, 5 September 2011 (CEST)
