Safe Mode Logon Password Keying Problem
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. -- Dick K |

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. -- Dick K |

Safe Mode Logon Password Keying Problem
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. |

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

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. -- Dick K |

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. -- Dick K |

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. -- Dick K |
