Extending the previous post, I have now added on the extra code to cut the sound off when you hibernate, shut down or restart. The complete script is listed below:
Code:
; AutoHotkey Version: 1.0.48.05
; Language: English
; Platform: XP SP3 (Not tested on other systems.)
; Version: 10 Feb 2010
; Author:
;
; Script Function:
; Template script (you can customize this template by editing "ShellNew\Template.ahk" in
your Windows folder)
;
/*
Mute on hibernation, restart or startup
Purpose:
Mute the internal speakers if the computer is sent into hibernation, restart
or a subsequent startup
IBM/Lenovo laptops, e.g. T43, produces a pause with an error message and two beeps
at start up if the IBM hard disc is replaced with a on-IBM hard disc. While the error message
will still be delayed, a BIOS change will set the start to continue after 3 seconds, but it
still beeps. This script is designed to mute the sound at hibernation, etc. and turn it back on
-unless, with hibernation, it had been turned off beforehand.
With a restart, or a subsequent startup, the sound is turned back on.
BE AWARE:
If there is a fult at boot time, IBM laptops give a series of beeps, which can be interpreted
to determine the cause. This script will mask those beeps, although it is likely that an
error message will be displayed. In such circumstances it may be necessary to disable
this script.
Functioning:
The program runs in background, listening for the system´s message to hibernate
the computer. It then mutes the speakers and turns them on again after the
computer woke up.
The mute state is left untouched in case the speakers were not muted by this
program.
The program will use one registry entry to save the mute state.
Requirements:
- Windows XP SP3
- Read and write permission to HKEY_CURRENT_USER registry stem.
- Registry entry HKEY_CURRENT_USER\SessionInformation\MutedforSuspend
- AutoHotKey.exe
- An icon called MuteOnHibernate.ico, for the system tray, or alternatively comment out
the line 'Menu, TRAY, Icon, MuteOnHibernate.ico, 1, 1' below.

I hope that others find this useful.
Note: AutoHotKey allows one to compile the above, as I have done, and locate the .exe file with the system tray icon. A shortcut to the .exe in the startup folder will then cause the script to run from powering up.
