I apology for being unclear,

2. Laptop-Fred was in my mind a shell variable, call it var_laptop_1 if this is better and this vari2ble would have to store the ip address 192.168.0.10 of the laptop we are trying to identify

3. From the result of nmap in this dhcp configuration the mac address X1:X2:3X:X4:X5:Y6 corresponds to 192.168.0.10

Thank you very much for your help,
freddie50

NAME
/usr/sbin/laptop_mode - apply laptop mode settings SYNOPSIS
/usr/sbin/laptop_mode [ cmd ] [ force ] DESCRIPTION
This manual page documents briefly the /usr/sbin/laptop_mode command. laptop_mode is a program that applies the settings given in the /etc/laptop-mode/laptop-mode.conf configuration file. The primary use is to control the laptop mode feature included in Linux kernels with versions 2.6.6 and higher, and 2.4.23 and higher. This feature increases battery life by letting your hard drive spin down. This is achieved by grouping disk write activity into "chunks" that are spaced at larger intervals than they normally would be. In addition to sup- porting the Linux kernel's laptop mode feature, /usr/sbin/laptop_mode also supports various power saving modules which are configured through configuration files in the /etc/laptop-mode/conf.d directory. It is not recommended to call /usr/sbin/laptop_mode directly to start or stop laptop mode, except in hardware event handlers. To apply new configuration settings from laptop-mode.conf, call the laptop-mode service init script with the reload parameter. COMMANDS
Specify force as the second parameter to force laptop_mode to re-apply a state even if the computer is already in that state. These are the values that are allowed for cmd : auto Enable or disable laptop mode based on the current power state. Note that this will not do anything if the laptop-mode service has not been started! status Display a status report about everything that laptop_mode affects. SEE ALSO
