Re: ApUsbPnp hanging at shutdown

Actually, it MAY be the problem with a device being shutdown to save power,
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?

OK, I did a clean install of Windows XP on my Fujitsu N6010. I
installed 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".

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:
