Power Management Modes
In win2000 example (other systems and win2000 are similar) in the control panel there is a "Power Options" (as shown in Figure 1), open the "Power Options" appears "Power Options Properties" window (shown in Figure 2), You can see the "Power Schemes" tab within the "Power Configuration" option, the "home / office type", "Portable / Laptop", "demonstration", "Always On", "Minimal Power Management" "Max HP Pavilion dv1600 Battery" and other projects. When you select a different power configuration item, the bottom will display a different power settings. To "turn off the monitor / Average Power / 10 minutes", it represents is the "general power supply connected to the situation, do not touch the keyboard or mouse will turn off the monitor after 10 minutes of power," so we can achieve the purpose of saving . For example, when you use the computer, suddenly received a customer's phone chat after 10 minutes, the computer will automatically turn off the monitor power, until you touch the computer again, it will open again.
You can also choose different time settings, save one called "best node" power settings, all the options are set at one minute without touching the computer, then turn off the monitor to enter the "System Standby" mode, so that a certain is the most power. If you still do not understand the above description, as long as careful about "turn off the monitor," "Turn off hard disks", "System Standby", "System hibernates" the length of time, you can appreciate the differences it.
The so-called "System Standby That is, when the computer after a period of stagnation, the system will store the current working-memory and peripheral (monitors, hard drives, etc.) the power off, but the power is still turned on (power indicator is still lit ), as long as you touch the mouse or keyboard, the computer will revert to your original working state. As for the "System hibernates" sucked in-memory data stored on the hard disk, and the computer is off (power indicator is off), At this point as long as the re-press the key to open the computer will revert to your original working state. WindowsXP default value is not open "system sleep" mode, you must have the "Power Options Properties" window under the open "sleep" tab and "Enable Hibernation" check box is ticked, this way, you can in the "Power Schemes" tab to see "System hibernates" setting. want a quick look at the current remaining HP Pavilion dv1400 Battery usage, in addition to the console Open the "Power Options Properties" window inspect the battery meter, "but you have to do in the" Power Options Properties "window of the" Advanced "tab click the" Auto Show icon on the taskbar ", you can work out through the battery (or power cord) icon, relaxed look to the power remaining in the battery.
Accurate estimation of the available time
Observation time you do not know the HP Pavilion dv1200 Battery usage time much longer? Then you can click the battery icon in the Windows taskbar for this information, but it only shows the percentage of battery power remaining. Bgauge 1.01 (this program can be obtained free of charge from) is a very handy little utility. They are able to track the battery under Windows 9x/NT/2000/xp usage, record the way you work, and according to the current battery charge status more accurately estimate the remaining time available. There is also a Ming Xiao current stock of laptop power method: actually very simple! Laptop running Windows, the taskbar will appear on a kind of small battery icon, the mouse pointer moves over it, it will show the current battery residual quantity. As long as the mouse pointer over the battery icon, and you can know how much power left. The battery icon with the mouse on the point of two, there will be power meter, you can more clearly see the current battery situation.
But when the HP Pavilion DV1000 Battery after a certain age, Windows shows the percentage of battery power will be inaccurate, and even some new batteries or when this will happen, the battery to 0% can also use half an hour or one hour, or the electricity and 30 % on the automatic shutdown of the uncommon instances, this is because the Windows power management design is not compatible with all batteries due. Especially in the secondary laptop battery is more likely to have this problem. This does not mean that the battery problem, it is better to own or PCMark2002 with Battery Mark test to determine the actual time (need to turn off all power-saving options to avoid Windows wiseacre intervention).
HP G71t Battery saving hardware articles
Laptop power consumption of various hardware to make a simple descending sort is: "LCD, optical drive, hard disk, CPU and memory, other (interface, the external equipment, etc.)."
Have to mention here is the display. Entirely from the brightness of the LCD panel placed in the rear of the back lamp, so one can imagine, the level of brightness of the lamp power consumption is brought definitely not the same. So if you are using HP G71 Battery power, to the extent permitted in the visual, as much as possible to reduce the display brightness can save some energy. The all-black background with respect to those fancy background do reduce the consumption of the system, but this is minimal energy savings, but also brought about not an LCD, because no matter what the background, the LCD brightness there is no change in terms of. Therefore, we recommend you leave the computer when you can select the LCD off, or use the hibernate feature, or even shut down your computer.
Meanwhile on the issue in the memory than DDR SDRAM power, because DDR memory voltage is 2.5v, while the ordinary SDRAM memory is 3.3v. It is recommended that you buy a machine to pick the best attention to DDR memory!
After the above operation, the HP G70 Battery usage time can probably be extended in terms of a relatively long time ago, sounds like the role that optimization is not so obvious, but do not underestimate the time available, it is perhaps the most critical moments become important computer data straw. Protect the battery is not equal everywhere worried or without the battery, as long as the attention to the temperature of the environment, pay attention to the correct way to charge and discharge, pay attention to proper storage, proper use of power adapter, etc., at a reasonable operating under the premise can boldly use !
