ApUsbPnp hanging at shutdown
Martin Murray
all the device drivers from Fujitsu and have done every Windows Update.
None of the devices appear to have complaints.
There is a USB mouse attached to the laptop, but both the mouse and the
internal touchpad are enabled and working.
Periodically, and I think this only occurs after the system has been on a
while (and maybe only after the screen blanks after inactivity), things
begin to go wrong.
Graphics begin to get flaky sometimes, the LAN stops working sometimes, or
maybe the Start button brings up a garbled list of options, but there is a
problem. When I press control-alt-delete to bring up TaskManager, I get an
error. If I try to Shutdown from the Start Menu, I am told I don't have
permission to shut it down. But I can press control-alt-delete and to
Shutdown from that menu and then I get a Program Not Responding window
referencing "ApUsbPnP". So, I'm guessing that is at the core of the
problem. I have no idea what the heck that is!
Any help will be appreciated. Thanks in advance.

The few articles I found on "ApUsbPnP" suggest you have a trojan horse.
In general, any device that stops working after hibernation might need this:
Open Device Manager, open the properties on the device, or each of your
USB ports, click the Power tab, and deselect "Allow the computer to turn
off this device to save power".

VERY careful besides. I don't tthink it is a trojan horse.

OK.. But I also suggested a fix for loss of some device usage after
hibernation.
Oh, and there's this.. Adaware won't catch everything. Nor will
Spybot, or any other software. A Trojan horse, in particular, is seldom
caught by anti-spyware software; it's usually caught by antivirus
software. But it's just as usual that, if you are infested, the
infestation disabled your av software, and runs a fictitious, or
incomplete scan so you think you're not infected. You might want to do
an online scan just as a precaution. I hate to keep harping on the
malware "solution" though.. here's the few posts I've found on that file:

suggested. Most are in foreign languages.)

even though the laptop is on wall-juice. I have disabled that feature in
Device Manager as you recommended, and we'll have to wait to see.
I connected a USB hard drive at one point and the system did not see it
until I rebooted, indicating the post may have been asleep.
Where do I find an online malware scanner?

far as I can detect. It is also not because the LAN went to sleep, 'cause I
turned that feature off also. Additionally, I reinstalled the ATI video
drivers.
The problem still occurs. What the heck is ApUsbPnp???

You might do a search for it on the hd. If found, right-click, click
Properties and see if it has any information on the author, etc. What
folder is it found in? That could be a clue..

One other thought; it could be associated with a specific hardware
component, one that plugs into the USB port, possibly a router or modem.

right now either.

Click Start, Run, type REGEDIT, click OK. Press the Home key, press F3,
type the name of the file into the search pane. Click "Find Next", and
see if there's a reference to the file there. Please report back if you
find anything on it.
BTW, this thread also mentions a Fujitsu laptop. It could be one of the
drivers for that manufacturer's devices. In that case, you might try
their support. Also look for updates from Fujitsu.

conversation.
My Fujitsu drivers are all up-to-date. No ApUsbPnP text in the registry.
My Virtual Memory setting was a custom number for some reason, so I've
changed that to automatic. Is there some number I probably should be using?

Why did you reinstall? Were there problems beforehand?

Graphics problems could be caused by the ps, the graphics card, or
the motherboard.
The hd could be the problem; that could cause fonts to be corrupted.

I haven't reviewed the whole thread so if this is a duplicate my apology.
What happens in safe mode? If you start in safe mode and then immediately
logoff does the error occur?
In normal mode if you start the computer, login and immediately logout
without running any programs does the problem occur?
If it doesn't happen in safe mode but happens in normal mode upon a
login/logout, do some clean boot troubleshooting:

Other questions to consider. What happens is you create a new admin level
account? Still occur? A new limited user account - still occur?

Martin,
Sorry to be replying to such an old post, but I'm having the EXACT same
problem you did back in 2007 with your Lifebook N6010. Were you ever
able to resolve the problem?
Personally, I think this may be a hardware problem with the
Motherboards of the N6010. The program that is hanging (apUSBpNp) is, I
believe part of Itunes. I have no information to substantiate this, just
going on instinct. I think the problem comes from disconnecting an Ipod,
shutting down Itunes, then later trying to shut down the computer. Just
a theory anyway.
