Help - Repeatable X200T USB, Sleep and Lock/Restart/Shutdown crashes

2010-08-20, 13:23 PM

Hi all,

Over the past few months I've been using an X200 Tablet with Windows 7.  Since I've had it I've noticed problems with it not 'sleeping' properly and the ability to Lock, Restart or Shutdown the computer going missing.


I’ve done some troubleshooting and narrowed down a scenario where I can repeat the problem 100% of the time. 


-       Setup computer with USB device (a keyboard and mouse will do)

-       Boot and logon

-       <test to see if locking works, and unlock – it works>

-       Sleep the computer

-       Wake the computer

-       <test to see if locking works, and unlock – it works>

-       Unplug any of the USB devices


At this point the computer can’t be locked, and if you send it to sleep it will essentially crash meaning you have to do a hard shutdown (or as has happened a few times, wait for the battery to run out in your laptop bag...).  I’ve tried different USB ports on the computer and different mice.  I've updated the BIOS and all the drivers, I've even rebuilt it from the Windows DVD. 


Is something anyone else has experianced?  If you have a X200 tablet does the same thing happen to you?

USB-C: Just cos it fits don't mean it works.
I don't work for Lenovo. I'm a crazy volunteer!

Out of the blue, I happened to install this Microsoft hotfix (http://support.microsoft.com/kb/976755), and today was the first day that, upon docking, I was able to lock my laptop, and I assume it will go to sleep at the end of the day when I take it home.


In checking this forum, I see that this fix was suggested here some time ago:



Hope this helps.
