You can read about laptop power profiles in Chapter 35, "Hitting the Road," but I tell you a little about how to drill down into the power management settings here. It's not different - it just works on a desktop PC.
What we have now is effectively what laptop computers have - a power profile that includes battery settings. Well, this service was removed in Windows Vista, and is likewise missing in Windows 7. If the UPS you purchase (or already own) doesn't come with Windows7-specific drivers for shutdown and warning features, contact the vendor for a software update. The message could alert users to save their work and power down their computers, for example. Typical events were such things as running a program or sending out an alert to all users or admins on a server about impending doom. If the UPS signaled that a power irregularity had occurred and power was about to go down, an event or series of events could be triggered. This was a service that monitored a serial port for a warning signal from a UPS. Windows 2000 and XP had a function called Windows 2000 UPS Services. Such units are often called intelligent UPSs. This cable sends signals to your computer to inform it when the battery backup has taken over and tells it to start the shutdown process some units may also broadcast a warning message over the network to other computers. Many (but not all) UPS models feature a serial (COM) or USB cable, which attaches to an appropriate port on your system. As soon as AC power gets flaky, the UPS has to take over within a few milliseconds, at most. A UPS plugs into the wall (and can act as a surge suppressor), and your computer and monitor plug in to outlets on the rear of the UPS.Įlectronic circuitry in the UPS continually monitors AC line voltage should that voltage rise above or dip below predefined limits or fail entirely, the UPS takes over, powering the computer with its built-in battery and cutting off the computer from the AC wall outlet.Īs you might imagine, preventing data loss requires the system's response time to be very fast. You can also buy USB monitor adapters if you prefer.Ī battery backup unit (also called a UPS, which is short for uninterruptible power supply) provides battery power to your system for as long as an hour, which is more than enough time for you to save your data and shut down your system.

If you don't have enough open slots to install all extra adapter(s) needed for multiple monitors, look into quad-link video adapter cards that support four monitors (most modern cards support two these days). "Backing Up the Registry" is covered on p. Managing backups is discussed in the section "The All New Backup and Restore" p.
