timeout option.
Modem Timeout
Fax modems - whether built-in, or on a PCMCIA card - use a lot of power, even when they're not
in use. For the internal fax modem, we have provided an inactivity timeout that significantly
reduces power-consump_ tion when it powers down the modem. The modem will automatically
restart when your communications software accesses it, so you should use this feature. If you're
like most people, you'll use the fax modem infrequently, so you can increase battery life by
leaving the default setting at "60 seconds." You can change the interval in ten-second
increments. You can disable this feature, but you will barely notice any effect on modem
performance with the option enabled.
You should note that some communications software written in the days before power
management or portable computers were available cannot tolerate timeouts like this. If you have
software with this problem, don't use this feature while you're running the software. Also, if you
use your modem for file transfers - for example, downloading files from a BBS try disabling this
feature if you experience communication problems. If the problem clears up, leave the timeout
disabled.
Audio Timeout
This sets the interval of inactivity after which the optional audio card will enter low-power mode.
The default setting is "02 minutes." You can

change the interval in one-minute increments. You can also disable this feature.
Normally you will want to use this, but you could possibly experience audio problems with some
games and multimedia programs under Windows and DOS. If you have an audio problem while
using a program, try disabling this feature. If the problem clears up, leave this disabled while
you're using that program.
Auto Dim
The default setting for this is "Enabled." When enabled, and the computer is operating on battery
power, at maximum brightness the backlight will be 30% dimmer than its actual maximum
intensity. This has the same effect as reducing the screen brightness using the manual control,
but it does it automatically, and to a fixed degree. The backlight will automatically operate at full
intensity while using AC power with the Auto Dim feature enabled.
CPU Clock Throttle
Clock throttle is a special hardware feature which automatically stops the CPU clock at routine
intervals regardless of system activity. Although it decreases CPU performance by about 10%, it
results in a 10% power saving. If you want the highest performance possible, disable this feature.
If you want to extend battery charge-life, enable it.
