Safe Mode Logon Password Keying Problem


D

Dick K

I'd be grateful for some help with a problem which
has developed on my desktop system which runs XP MCE
2005 with all critical updates and has a cordless
keyboard and mouse from Logitech. Unfortunately I
don't know when the problem first occurred so I
can't associate it with any particular circumstance.

When attempting to logon to a password protected
account in safe mode via either the welcome screen
or the classic logon prompt the cursor duly appears
but key depressions have no effect when an attempt
is made to enter the password. The mouse works
normally. If the password is removed from the
account to be accessed a safe mode logon proceeds
normally, though of course no password needs to be
keyed. Having logged on successfully the keyboard
functions normally within safe mode. There are no
keyboard or logon problems in normal mode.

Nothing apparently relevant appears in the event
logs and device manager shows no problems in normal
or safe mode. msinfo32 lists one problem device,
a PS/2 keyboard, but under error code correctly
states that the device is not present or has no
drivers installed. Device manager doesn't list a
PS/2 keyboard.

Look here (at the answers too, and especially the answer at the bottom):

Thanks for the response. Until recently I have
been able to logon in safe mode by entering the
password via the Logitech USB wireless keyboard
in the normal way, so the set-up was correct.
Now keying the password, or indeed pressing any
keys at the logon prompt produces no visible or
other effect. Something must have changed to
create the problem. F8 still gives me the
option to select safe mode so any drivers
must be loaded and working at that point. Also
the keyboard still works normally once I
I have logged on in safe mode. I can only think
that something has gone wrong with winlogon's
password handling in safe mode.

The other suggestions in your link are
workarounds but I already have one of those -
removing the password from the target account
eliminates the password problem because no
password needs to be entered.

I am latching on to the word "recently". If this is a recent issue then
System Restore will fix the problem for you.

True. The problem may be a two or three months old
though, so I may no longer have a suitable restore
point. In that case I could still restore a back-up
image file but I'd prefer to avoid either expedient
if there's a known fix. If the problem is
relatively old updating the system after restoring
it could be something of a chore and would carry
the risk of recreating the problem.

Anyway, thanks for the suggestion.

install the software that came with the keyboard and mouse, most of the
time wireless devices are unable to be used in DOS "safe mode". My
wireless devices can't get me to safe mode, I keep a wired keyboard in
hand. if you have installed the drivers then try to uninstall and
reinstall maybe a small bug that the computer can work out.

Thanks. It's a Logitech 650 Cordless Desktop De Luxe
keyboard/mouse set which connects via USB , uses
Windows drivers and still works in safe mode. The
problem is that in safe mode it simply won't let
me get into a password protected account by keying
the password. If needs be I'll look into the
possibility of driver corruption but I'll need a
PS/2 mouse and keyboard for that.

Why are you using windows drivers for Logitech mouse ?

I think I may have been mistaken here - at least I
never again got the keyboard working in safe mode.
There are no
keyboard or logon problems in normal mode.

Nothing apparently relevant appears in the event
logs and device manager shows no problems in normal
or safe mode.

This go-round device manager showed a keyboard driver
error in safe mode "Windows cannot initialize the
device (Code 37)".
msinfo32 lists one problem device,
a PS/2 keyboard, but under error code correctly
states that the device is not present or has no
drivers installed. Device manager doesn't list a
PS/2 keyboard.

My last round of driver updates upgraded the keyboard
driver from "HID Keyboard Device" to "Logicool HID
Compliant Keyboard (106 keys)". Rolling the driver
back cleared the problem. Humiliatingly obvious
in retrospect.
