Hibernate your PC !Reduce the total power consumption of your PC by closing or hibernating it. Your PC goes to S5 state, where everything is copied to special file from the memory and the power is shut down. When you want to start again, you just press Power on. The PC starts and loads everything to the state it was before hibernation.One good method is to make PC hibernate automatically at a prescheduled time. You can possibly find many programs to be used for this, but here is one: SHUTDOWN.EXE (Original site of Andrej Budja at 21.06.2004) Here is how: -download SHUTDOWN.EXE (This is a copy in my server). You can check and change the parameters selecting Start + Control Panel + Scheduled Tasks. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||

Enable the Power Management feature for your monitor (see below on how to get instructions). 4. If you buy a new computer, consider a laptop. Laptops use only 1/4 the energy of a desktop*. 5. If you buy a new monitor, consider a flat screen. They use only 1/3 the energy*. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||
InformationweekMost PCs today support six distinct power modes, or "sleep states," commonly defined as S0 through S5. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||

One of the most common problems with Windows is its abysmal support for
APM (Advanced Power Management). Either Windows won't go into power saving mode
when you want it to, or it insists on putting your system in "standby"
mode even when all power management options are disabled. Either way, it isn't
fun. * Windows 95 has minimal support, and therefore doesn't pose much of a
problem. Regardless of your OS, you should check your system BIOS to see if APM is properly enabled and configured: * Enter your computer's BIOS setup (press DEL or ESC or something like that
just after turning on your system, and your computer is counting through your
memory). Contact your computer's manufacuter or refer to your computer's
documentation
for details specific to your computer. Then, set your power-saving preferences in Windows: * Double-click the Power Management icon (called Power or Power Options in
some versions of Windows) in Control Panel. If it isn't there, your computer
isn't
properly set up - see above. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Informit However, APM has a major limitation in that it focuses on the system board and device access information when determining whether to power down devices. The BIOS might know that a PC Card device is present, but it has no way of determining if the card is actually being used. If the hard disk is being used, the BIOS has no way of determining if it is being used by a program or if the operating system is just using it as a page file for virtual memory. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Lawrence Berkeley National Laboratory"As of early 1996, the EPA estimates that upwards of 70% of all new PCs and
nearly 100% of all PC monitors sold have power management capability." "Power management can only save energy if it is enabled and working properly." " the monitor usually consumes at least twice as much electricity as the CPU" "Power-management does not reduce the performance of a computer, but simply adds features to reduce their power consumption when not in use. These energy-efficient machines save money on electricity bills and reduce pollution from power plants." | ||||||||||||||||||||||||||||||||||||||||||||||||||||||
