Hi all, when I'm working on T60 in Advanced Mini Dock and unplug power adapter, system totaly freeze. Then when I plugin the power back, I get bluescreen:

*** Hardware Malfunction
Call your hardware vendor for support
NMI: Channel Check / IOCHK
*** The system has halted ***

My friend have also the same problem with T60 and MiniDock. I run PC Doctor, he don't find any problem. Have anyone else the same problem ? Is there any solution for this ?

Thanks for any help.

wow, I just tried that and got a hang on a first try and exactly the same bluescreen on the second try using my T60 and Advanced Mini Dock! Very much looking forward to answer if there is a solution to this.

Information for everyone that have the same problem - contact Lenovo service, they will change mainboard, it is a hardware malfunction that is known in some T60 series.

I don't understand the problem. The Advanced dock requires power to operate. It makes sense to me that if you remove power it will fail. Why in gods name would you want to remove power while the TP is docked anyway?

Imagine you are working on important project and power fail (in place where I live it is a normal situation when there is strong storm). Work is lost.. Not everyone want to buy UPS for notebook.
I tryied to unplug power from dock with Z60t and notebook switch to battery with no problem.

I see. Does this only effect T60's?

I have only information about T60, hope this is really extraordinary problem of some T60 series.

maybe someone with a T61 and this dock could try this out and report back to the forum?

I'm typing this on a T61P on an Advanced mini-dock. I just pulled the plug and kept typing on the TP keyboard after I opened up the lid. This is on Linux ... What also might be interesting is to have someone with the T60 minidock problem boot up a knoppix or other Linux live CD to see if the problem still occurs.

I'm waiting for my adv mini-dock to arrive. Once it does, I'll try to find out what happens with the Ubuntu 7.10 live CD. I currently have XP on my new system, but I plan to eventually have a dual boot system.

I have a T60 (2007-FUG) with Advanced Mini Dock. Once there was a power failure and the computer has frozen, maybe bluescreened, not sure, it's quite a some time ago.

Though, since then, I was "reconfiguring" the use of power outlets by devices, had a T60 in the dock running, and disconnected/reconnected it about three times during a short timespan and it always undocked and then redocked properly. Not sure though if a real power outage (which means other connected devices lose power at the same time) wouldn't cause the problem again.

The only thing that has changed since than is I'm using only one USB device, instead of three back then. So you can perhaps try simulating outage without the USB devices connected. Also try powering off bluetooth before doing so.

You got it in one Harry... an "act of God", such as an external mains power failure, will do it!

Given the TP has a battery, I would expect that in the case of power going off at least the Thinkpad would keep running, even if some of the dock function may not.

Cheers,

Just got a T61p with an advanced mini docking station. I decided to change outlets and had pulled the plug on my docking station while the TP was docked and running. Ran across the same exact crash and error. Lenovo suggested trying in safe mode and the same thing happened. They are going to ship me a new docking station but I am not sure this will solve the problem. If it doesn't, I wonder if it's worth going through the hassle of replacing the TP as it is a brand new purchase. Can this problem cause corruption in the future despite not occuring very frequently? Anyone else with a similar experience who found resolution?

Hi everybody, finally Lenovo solved the problem.. After replacing 5 mainboards of my T60 and only one works well with dock unplug, they told me that problem is in docking stations of some production series..

Few days ago they released new bios update (version 2.21), which add new option in bios setting, in Config is now Docking Station option. Here you can enable or disable serial and paralell port on dock (Legacy Devices on Mini-Dock), when you select Disabled, the problem with bluescreen and hang is solved. But for price, that you will have serial and paralell port on dock disabled..

T61 series have no problem with this docking station.

Version 79ETE1WW (2.21)

(New) A new entry added in BIOS Setup that switches serial/parallel ports in a docking station enabling/disabling. A disabling will make a ThinkPad free from hang up when an AC power cable is unplugged mistakenly. Disabling will make those ports unusable

wow.. it's actually there huh

Cool.. we helped contribute there for sure.

Confirmed that with BIOS ver. 2.21 I no longer see a blue screen with a crash.

I do wonder though about those folks who actually use parallel and serial ports in their mini-docks....

Was reading this and decided to unplug my R61 from it's advanced dock, froze right up! Called Lenovo and they confirmed that I should be able to unplug the power from the dock and the TP should have no problem shifting to the battery.

They are sending out a new docking station so we will see how that works.
Also could not dock in sleep mode with out freeze.... we will see if it's the dock and I'll report back.

boatdoc · #18 Post by **boatdoc** » Tue Mar 18, 2008 6:19 am

Ok new dock showed up and the same old problem. Power loss= freeze. Now they want to replace the motherboard. I'm beggining to think Lenovo is headed down the toilet after talking on the phone with tech support today. "no sir we are not aware of any problems with power loss why'll docked"

Mr. Carl Moon and Richard Wilson all though nice and polite, I think your full of it!!!!!!!!!!

Yes I have a T61 which also gives me the Blue Screen of death when docked and experience a power failure. (In South Africa this happens frequently at the moment).

I worked around the problem by using the advice from this forum.

I disabled the Legacy Devices (which are the paralell and serial port ofthe docking station) under the Docking station options in the Bios. This worked fine.

Thanks for the help All !

Same issue with T500 on mini-dock....

bassfreak · #21 Post by **bassfreak** » Thu Apr 23, 2009 11:16 am

Same issue on a T61 with the Advanced Mini-Dock. I will try to disable those ports to see if this still happens.

dcg · #22 Post by **dcg** » Thu Apr 23, 2009 12:24 pm

bassfreak, I tested it on T61p after we finished talking on messenger. Without the "fix" system froze promptly. I went to BIOS to "docking station options" and changed the setting to "disabled". Now I can pull the plug without worries. Lucky me, I don't use the serial and parallel ports. Thx for the tip, i won't be bothered to test it on my other Thinkpads, it's clear it will do its charm
